1 The different acquisition methods and investigative modalities, as well as limitations associated with cadaver studies and technical aspects of imaging studies, may explain some of the discrepancies among wrist kinematic theories and descriptions [49]. wrist ligaments, wrist injuries, wrist ligament anatomy, diagnostic modalities. sharing sensitive information, make sure youre on a federal 4 62. Inclusion in an NLM database does not imply endorsement of, or agreement with, The extrinsic wrist ligaments are illustrated as labeled. 53 -> forearm supination -> wrist ex. Schmid M R, Schertler T, Pfirrmann C W et al. Innervation to the wrist is delivered by branches of three nerves: The scaphoid bone of the hand is the most commonly fractured carpal bone typically by falling on an oustretched hand (FOOSH). Pulos N., Bozentka D.J. On the posterior side are three primary wrist extensor muscles: the extensor carpi radialis longus (ECRL), extensor carpi radialis brevis (ECRB), and extensor carpi ulnaris (ECU) (Table 3). Lu C, Wang P, Zhang L, Dong J, Zhang H, Yang L, Wang X, Xiong H. Orthop Surg. 21 Youm Y., McMurthy R.Y., Flatt A.E., Gillespie T.E. The RSC ligament is the most superficial and radial of the extrinsic palmar ligaments. The abduction is produced by the FCR, ECRL, and ECRB. The proximal row consists of the scaphoid, lunate, triquetrum, and pisiform. Although a recent systematic review found arthroscopic and open approaches to result in comparable outcomes, the study emphasized the need for further prospective studies comparing surgical approaches. Manal K., Lu X., Nieuwenhuis M.K., Helders P.J.M., Buchanan T.S. Clipboard, Search History, and several other advanced features are temporarily unavailable. Unglaub F, Wolf M B, Thome M A, Germann G, Sauerbier M, Reiter A. 44, Several imaging modalities have been used to evaluate TFCC injuries with varying degrees of success. However, these tests have variable efficacies, with the ballottement test having only a 64% sensitivity and 44% specificity, thus additional diagnostic modalities should be employed. Access over 1700 multiple choice questions. 46 A unifying model of the wrist biomechanics and functional carpal kinematics, respectively, remains elusively [6]. The https:// ensures that you are connecting to the He divided the carpus under a functional aspect: the carpus so defined is divisible into three masses: the navicular (scaphoid) bone; the lunate and triquetral bones together; and a distal mass formed of the hamate, capitate, and trapezoid (lesser multangular) conjointly. Trehan S K, Wall L B, Calfee R P et al. Eschweiler J., Stromps J.-P., Fischer M., Schick F., Rath B., Pallua N., Radermacher K. Development of a biomechanical model of the wrist joint for patient-specific model guided surgical therapy planning: Part 1. The DCR are rigidly bound to one another via stout ligaments, and the motion between them can be considered negligible [9]. Bateni CP, Bartolotta RJ, Richardson ML, Mulcahy H, Allan CH. The lunate is forced anteriorly, and compresses the carpal tunnel, causing the symptoms of carpal tunnel syndrome. They are interposed between the forearm (radius and ulna) and the five metacarpal bones (Figure 1). 51 Bookshelf This site needs JavaScript to work properly. The wrist joint is a diarthrodial joint and is built up of eight unique carpal bones. 87 There is one primary dorsal extrinsic ligamentthe dorsal radiocarpal (DRC) ligament. Iwasaki N., Genda E., Minami A., Kaneda K., Chao E.Y. In detail, the ring model describes the motion behavior such as the following: movement by one row is in the opposite direction from that by the other [52]. Typically, flexion of the scaphoid causes palmar flexion of the lunate via the SLL connection. 8A The motion of the wrist joint is initiated by the muscles of the forearm, and strong and short ligaments ensure the stability of the wrist. To understand and treat wrist injuries and degenerative changes, it is essential to understand the carpal biomechanics [3,4,5]. 46 The central point of this concept is the observation that RUD and FE occur reciprocally between the radiocarpal and midcarpal joints [10,52]. The lunate contact area averaged 55.7 mm2 in flexion and neutral position and increased to 78.6 mm2 in extension [67]. Rohde R.S., Crisco J.J., Wolfe S.W. The site is secure. Patients with a missed scaphoid fracture are likely to develop osteoarthritis of the wrist in later life. reported on carpal kinematics during simulated active and passive cadaveric wrist motion using an optical tracking system [45].

Acta Chir Orthop Traumatol Cech. Lee D J, Elfar J C. Carpal ligament injuries, pathomechanics, and classification. Thus, the authors present this review detailing anatomical considerations, functional implications, common injuries, evidence-based diagnostic modalities, and surgical management of the most clinically relevant wrist ligament injuries. 2021 Aug;50(8):1605-1616. doi: 10.1007/s00256-020-03701-8. There exists still a controversy about the existence of a center of rotation of the wrist. The centers of the contact areas change location with changes in wrist position as do the areas of contact [2]. Furthermore, rupture or attenuation of the LRL and SRL ligaments may occur with scapholunate injury. In vivo analysis of carpal kinematics and comparative review of the literature. They include extrinsic and intrinsic ligaments where the extrinsic ligaments connect the carpal bones to the radius or metacarpals and include volar and dorsal ligaments. 2 Ritt M J, Bishop A T, Berger R A, Linscheid R L, Berglund L J, An K N. Lunotriquetral ligament properties: a comparison of three anatomic subregions. 2 articles feature images from this case 8 public playlists include this case Promoted articles (advertising) 16. It is actually a collection of multiple bones and joints. 10A Arthroscopic debridement to treat Palmer type 1A injuries has been found to be widely successful, except in the setting of positive ulnar variance, where the failure rate has been found to be as high as 30%. Their analysis showed that most of the joint surfaces of the lunocapitate and triquetrohamate joints are also part of the midcarpal ovoid. Genda E., Horii E. Theoretical stress analysis in wrist joint--neutral position and functional position. 2019 Aug;44(8):641-648. doi: 10.1016/j.jhsa.2019.03.003. Although rarely reported in the literature, ulnolunate injury can cause chronic wrist pain, locking and pain with grip, and be difficult to diagnose, requiring arthroscopic examination for confirmation. Findings are apparent in the background of severe inflammatory arthropathy, noting multicompartmental synovitis/pannus, diffuse cartilage loss, and erosive change. Early proximal row carpectomy after severe carpal trauma. Dart-throwers arc is one of the widely used wrist motion during daily activities [14]. The scaphoid bone of the hand is the most commonly fractured carpal bone - typically by falling on an oustretched hand (FOOSH). Disclaimer. ). Similarly, in chronic scapholunate dissociation with irreparable scapholunate ligament, a ligamentoplasty with a free palmaris longus graft was used to reconstruct scapholunate and DIC, resulting in improvement in pain and decrease in scapholunate angle. Moritomo et al. The dorsal radiocarpal ligament is a large extrinsic intracapsular dorsal radiocarpal ligament and one of the main dorsal stabilizers of the wrist 1-3. and transmitted securely. Limitations of MR imaging in the diagnosis of peripheral tears of the triangular fibrocartilage of the wrist. Scapholunate interosseous ligament tears: diagnostic performance of 1.5T, 3T MRI, and MR arthrography-A systematic review and Meta-analysis. The therapeutic (surgical) restoration of the balance between the loadbearing capacity and the actual stress on a joint is the prerequisite for a lifelong and trouble-free function of a joint. The DIC, which acts as a primary dorsal stabilizer of the scaphoid during wrist motion, works with the DRC to provide scaphoid and lunate stability. Fig 3 Radiograph of a scaphoid fracture. Treiser M D, Crawford K, Iorio M L. TFCC injuries: meta-analysis and comparison of diagnostic imaging modalities. Therefore, the PCR bones accommodate wrist RUD by palmarflexing and dorsiflexing, respectively [2,44]. Shin A Y, Battaglia M J, Bishop A T. Lunotriquetral instability: diagnosis and treatment. progress is being made and new data are accrued. 89. The extrinsic wrist ligaments include the dorsal intercarpal (DIC) ligament, dorsal radiocarpal (DRC) ligament, radioscaphocapitate (RSC) ligament, long radiolunate (LRL) ligament, short radiolunate (SRL) ligament, ulnolunate, and ulnocapitate ligament [15]. 3 J Bone Joint Surg Am. The PCR can be described as an intercalated segment [9]. The anatomy of the ligaments of the wrist and distal radioulnar joints. Future research could focus on the integration of material properties, kinematics, and kinetics. 29 Scaphoid pressure averaged 1.4 MPa and lunate pressure averaged 1.3 MPa and they did not significantly change between wrist positions [67]. They can be divided into palmar, dorsal, radiocarpal, and ulnocarpal. From a functional standpoint, carpal motion varies within each row, particularly within the PCR [2]. Kovachevich R, Elhassan B T. Arthroscopic and open repair of the TFCC. -> finger ex. The Classic: Injuries of the Wrist: A Radiological Study. Shahabpour M, Abid W, Van Overstraeten L, De Maeseneer M. J Belg Soc Radiol. ). Most of the carpal bones are directly attached to their neighboring bones through interosseous ligaments. TFCC injury can be classified using the Palmer classification ( The goal must be a patient specific and individualized approach to treat carpal injuries.

Ultrasonographic evaluation of normal extrinsic and intrinsic carpal ligaments: preliminary experience. Triangular fibrocartilage complex (TFCC). The wrist is a complex joint that allows movement of the hand in multiple directions relative to the forearm [2]. Sato R, Hibino N, Hamada Y, Sairyo K. Ulnolunate Ligament Avulsion Fracture of the Lunate: A Case Report. 8/17/2020. Study of operative approaches in a largely subacute or chronic patient population revealed that the probability of remaining complication free after 5 years was 68.6% for reconstruction, 13.5% for repair, and less than 1% for arthrodesis with significantly higher subjective indicators of pain relief and satisfaction in those receiving reconstruction or repair. Intrinsic ligaments that connect the carpal bones to each other. and transmitted securely. Laulan J., Marteau E., Bacle G. Wrist osteoarthritis. This includes that different regions of the ligaments differentially strained depending on the direction of the motion [6,26]. The closer packing of the proximal row is brought about by a two-stage process. Table2 0.0 (0) Login. ; project administration, J.E., F.M. Any reconstructive effort to restore scapholunate stability must reestablish radiolunate stability (the foundation) or else it will fail. Emphasis is placed on elucidating reported diagnostic accuracies and treatment outcomes to encourage evidence-based practice. Extrinsic ligaments that connect the carpal bones to the long bones of the forearm (radius and ulna) or the bones between the wrist and finger bones (metacarpals). The FE column includes the lunate, the capitate, and the hamate; the lateral column, or mobile column, includes the scaphoid, the trapezium, and the trapezoid; and medial column, or rotation column, consists of the triquetrum and pisiform [10,22,49]. The wrist relies on the unique bone morphology, their unique interaction with neighboring bones, and their extrinsic and intrinsic ligaments [15]. Each of them with a separate motion axis yet is interdependent on the position of adjacent carpal components and the carpal alignment with the distal radius [40,41]. Taneja et al. The motion is supported by the flexor digitorum superficialis muscle. The flexion is mainly produced by the PL, FCU, and FCR. Perhaps we should modify Navarros interpretation, because the pisiform does not actually participate in carpal motion and the trapezium and trapezoid are an integral part of the distal carpal row [22]. The RUD occur by rotation of the scaphoid laterally and the triquetrum medially [10]. 27 ). MacConaill published in 1941, based on his investigations at one human preparation, his theory about the working of the carpus as a unitary structure [54]. Extrinsic ligaments include several volar radiocarpal ligaments, volar ulnocarpal ligaments, and dorsal ligaments. There exist further functions of the ligaments, e.g., proprioceptive interactions [27].

The extrinsic ligaments of the wrist are defined by their attachments to the forearm, retinacula, and tendon sheaths in contrast to intrinsic wrist ligaments which only attach to carpal bones. The three-dimensional rotational behaviors of the carpal bones. Palmer 1B lesions can be repaired through open or arthroscopic means, with the latter approach having a variety of reported techniques including inside-out, outside-in, and all-inside. If an operative approach is indicated, a variety of options are available and the best one should be chosen based on injury severity and chronicity, with the goal of optimizing functional outcomes. The extrinsic ligamentous apparatus (Table 1) courses between the carpal bones and the radius or the metacarpals. 4 2 This condition typically requires concurrent injury of secondary supporting ligaments including dorsal radiocarpal, dorsal intercarpal, or ulnar arcuate ligaments; however, it can result from sprain of the LTL. The DCR bones behave as a unit that is moved by off-center forces. Bajuri M., Abdul Kadir M.R., Amin I.M., Ochsner A. Biomechanical analysis of rheumatoid arthritis of the wrist joint. Two ulnar-sided volar extrinsic wrist ligaments, the volar ulnolunate and volar ulnotriquetral ligaments, originate from the volar radioulnar ligament and insert on the lunate and triquetral bones, respectively (Figure 10). Furthermore, axial traction may increase the rate of detection of a TFCC tear. This unit also includes the metacarpals because of the interlocking of the articular surfaces and the dense ligamentous connections between the bones of the DCR and the bases of the metacarpals. Smith D K. Volar carpal ligaments of the wrist: normal appearance on multiplanar reconstructions of three-dimensional Fourier transform MR imaging. Thejoint capsuleof the wrist joint attaches to the radius, ulna and the proximal row of the carpal bones. Moreover, there exists clinical experience concerning ligament reconstruction and the performance of, e.g., partial carpal arthrodesis of wrist bones that still show unpredictable results. The ligaments contained in the UCLC play a controversial role in the stability of the ulnocarpal joint. Hyatt B T, Rhee P C. Longitudinal split tears of the ulnotriquetral ligament.

An official website of the United States government. The extrinsic carpal ligaments connect the forearm to the carpus and are contained inside the joint. The mobile column is limited to the scaphoid and the rotation column to the triquetrum. Majors B.J., Wayne J.S. Ligament injuries are called sprains. Treatment of SLL tears, according to the widely cited algorithm by Garcia-Elias et al, can be guided based on six parameters including whether the dorsal SLL is intact, if there is sufficient tissue to repair a dorsal SLL, if there is normal scaphoid alignment, if carpal malalignment is reducible, the lunate position, and if cartilage at radiocarpal and midcarpal joints are normal. The ligaments of the wrist. The site is secure. Broadly, these ligaments may be divided into volar and dorsal ligaments. Pederzini L, Luchetti R, Soragni O et al.

Intracarpal soft-tissue lesions associated with an intra-articular fracture of the distal end of the radius. Carpal bone size and scaling in men versus in women. The first stage of dorsiflexion is, then, one in which the clamp is set up, or constituted, by fixing the navicular, the fixed jaw of the vice, to the distal row, which acts mechanically as the base of the vice. Using these parameters, the severity of injury can then be translated into an appropriate operative approach that ranges from K-wire fixation with or without dorsal capsulodesis for a partial SLL injury to a motion-preserving procedure that relieves pain, such as a proximal row carpectomy or limited wrist arthrodesis, in cases of SLAC. In the row-column theory FE occur through the central column [10]. Yuan B J, Dennison D G, Elhassan B T, Kakar S. Outcomes after radiocarpal dislocation: a retrospective review. The major axis of this structure runs in a radiopalmar to an ulnodorsal direction (Figure 7A). The human wrist is a complex arrangement of bones and ligaments and functions to position the hand and transfer forces between the hand and forearm. The TFCC originates from the ulnar aspect of the distal radius and inserts proximally into the base of the ulnar styloid and distally onto the hamate, triquetrum, and base of the fifth metacarpal ( Patterson R.M., Williams L., Andersen C.R., Koh S., Viegas S.F.

Boer B C, Vestering M, van Raak S M, van Kooten E O, Huis In t Veld R, Vochteloo A JH. The idea of this division is the separation of the scaphoid (navicular) from the other bones of the PCR: it is based upon the observed fact that this bone moves at times with the proximal and at times with the distal row [54]. Unable to load your collection due to an error, Unable to load your delegates due to an error. Kijima Y., Viegas S.F. Treatment can initially involve conservative measures, including observation along with strengthening of the secondary stabilizers and radioulnar straps. The ulnotriquetral ligament is often injured through a single traumatic event, causing longitudinal splitting in the ligament due to weakness in the ligaments longitudinal direction from vascular perforations, as well as differing vectors of force transmission due to its split origins in the triangular fibrocartilage complex (TFCC) and the ulnar styloid. They are dedicated solely to the wrist and include on the anterior side the flexor carpi radialis (FCR), flexor carpi ulnaris (FCU), and the palmaris longus (PL). 2 Scapholunate Ligament Partial Tears; Tear Localization, Extrinsic Ligament Injury Association and Conservative Treatment Responses Prior to Instability: Cross-Sectional Study. the contents by NLM or the National Institutes of Health.

The extrinsic palmar RC ligaments are the most important stabilizers of wrist motion [44][45][46][47]. 37. The bones of the wrist are rigidly attached to each other by a series of ligaments resulting in limited movement between the bones [9]. The 3D configuration of a line connecting the centers of the joint surfaces of the midcarpal joint can be schematized as a letter C entwining a midcarpal ovoid (Figure 7). It is the result of complex interaction between bony structures and the intrinsic and extrinsic ligaments of the wrist .. Traumatic and degenerative lesions of the intrinsic carpal ligaments have been well characterized with several imaging modalities, including ultrasound, computed tomography (CT . Ultrasound allows for rapid, cost-effective, non-invasive and dynamic evaluation of the wrist, and may represent a valuable diagnostic tool.

Figs. and it extends from the palmar portion of the ulnar fovea to the capitate to join with fibers from the RSC ligament on the radial side to create the arcuate ligament, which is shaped like an inverted V. This can occur by falling on a dorsiflexed wrist. Slutsky D J. Arthroscopic dorsal radiocarpal ligament repair. In the second stage, the hamate acts as a screw to pin the lunate against the fixed jaw, and to hold it there for so long as dorsiflexion is maintained [54] (Figure 8B). In this review, the role of the radial-sided and ulnar-sided extrinsic and intrinsic ligaments is described, as well as their advanced imaging using magnetic resonance arthrography (MRA) and contrast-enhanced magnetic resonance imaging (MRI) with three-dimensional (3D) scapholunate complex sequences and thin slices.

Multiple explanations for intercarpal motion have been suggested, however the mechanisms for the degree and direction of motion of each carpal bone, that make up the two carpal rows, during motion in each of the planes, remain controversial [9,49]. Bones of the wrist from dorsal. It is comprised of dorsal, palmar, and proximal components, with the dorsal component being the thickest of the three and the most important stabilizer. ; writingreview and editing, J.E., J.L., V.Q., B.R., A.B., F.H. The TFCC is located on the medial part of the wrist between the lunate, triquetrum, and ulnar head. Patients with positive ulnar variance have an increased likelihood of developing TFCC lesions as demonstrated by increased numbers of apoptotic cells as compared with ulna neutral. In case of global wrist RUD, the PCR bones demonstrate a unique motion behaviour that is best described as reciprocal [2,43]. government site. 8600 Rockville Pike There was no significant difference in scaphoid and lunate pressure in all positions [67].

The management of dorsal radiocarpal ligament tears. Different researchers worked on this topic, e.g. Imaging key wrist ligaments: what the surgeon needs the radiologist to know. Slutsky D J. Injury to the LRL often occurs concurrently with other ligamentous injuries in severe, high-energy radiocarpal dislocations. The SLL is a C-shaped ligament connecting all but the distal articular surfaces of the scaphoid and lunate ( Acute and isolated LTL injury is uncommon, but can occur through a fall on an outstretched, pronated, and extended hand that is in radial deviation. The wrist ligaments have the responsibility of balancing the constraints to ensure the maintain stability while at the same time, allowing the generous ROM [27]. The peak loads across the wrist are quite low compared with those of other joints, ranging from 1.4 MPa (1 MPa = 1 N/mm2) to 31.4 MPa [2]. Berger R.A. The complex arrangement of the wrist's intrinsic and extrinsic ligaments and their biomechanics are challenging for the surgeon to diagnose the wrist pathology despite clinical examination. All authors have read and agreed to the published version of the manuscript. At the time the article was last revised Craig Hacking had no recorded disclosures. It is built up of a triangular fibrocartilage articular disc, in addition to the ulnomeniscal homologue, ulnar collateral ligament, dorsal and palmar radio-ulnar ligaments, the base of the extensor carpi ulnaris sheath, and the ulnolunate and ulnotriquetral parts of the palmar ulnocarpal ligament. There exists no ligamentous connections between the lunate and capitate. The different descriptions, classifications, and nomenclatures increase the complexity of understanding this region [17]. They are discussed above in further detail.

An essential property of a biomechanical wrist model is the possibility of evaluating the influence of, e.g., geometric parameters. Regarding the complex clinical problems, however, a valid biomechanical wrist joint model would be necessary as assistance, to improve the success of systematized therapies based on computeraided modelbased planning and intervention. The intrinsic and extrinsic wrist ligaments play a vital role in the stability of the wrist joint. Daunt N, Couzens GB, Cutbush K, Green J, Ross M. Skeletal Radiol. Gilford et al. 14 The dorsal radioulnar ligament (DRUL), like its volar counterpart, spans the distal radius and ulna, stabilizing the DRUJ together with the distal interosseous membrane.

The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The wrist is by far the most differentiated section of the musculoskeletal system. Bethesda, MD 20894, Web Policies For that, biomechanical modeling could be a possible approach. Visualization of these structures can be achieved by using high-frequency linear transducers. Wrist ligaments are best assessed with dedicated wrist MRI. Lee R K, Griffith J F, Ng A W, Nung R C, Yeung D K. Wrist traction during MR arthrography improves detection of triangular fibrocartilage complex and intrinsic ligament tears and visibility of articular cartilage. It is important to understand the basic science, and furthermore, the clinical relevance of functional kinematics of the wrist jointdefined as those motions that are necessary to carry out high-demand activities of daily living [6]. Moritomo et al. ). The Colles fracture is the most commonfractureinvolving the wrist, caused by falling onto an outstretched hand. Advances in the Biomechanics of the Hand and Wrist. Muscles of the forearm especially for wrist motion. The PCR is described and acts as an intercalated segment between the radius and the DCR [9,10,11,12]. Lans J, Lasa A, Chen N C, Jupiter J B. Login. There is gross instability with manipulation. 28 Rainbow M.J., Wolff A.L., Crisco J.J., Wolfe S.W. ; methodology, J.E., J.L., V.Q., B.R., A.B., F.H. To understand and treat wrist pathologies, it is essential to understand the carpal biomechanics, including the function of the soft tissue, e.g., ligaments [3,4,5]. The RUD Movement from a palmar view (modified after [35]). Tay S C, Tomita K, Berger R A. Epub 2021 Jan 21. The scaphoid shift or Watsons test can be used to assess for scaphoid instability: the examiners thumb pressed against the scaphoid tubercle, while the patients wrist is moved from ulnar deviation and slight extension to radial deviation and slight flexion. Dynamic instability is apparent on radiographs, with these signs only visualized upon stress of the wrist with a closed fist or clenched pencil, and a normal appearance of radiographs at rest. described the socalled ring model of the carpus, with two mobile links [52] (Figure 5D). The primary palmar radiocarpal extrinsic ligaments are: radioscaphocapitate (RSC), long radiolunate (LRL), and short radiolunate (SRL) ligaments. 8600 Rockville Pike Additionally, triquetrum-lunate malalignment and alteration of the scapholunate angle may also be visualized in the event of LT dissociation with VISI deformity ( Before Most of the midcarpal joint surfaces are contained within a midcarpal ovoid; the carpal bones might be moving within this volume, but they still have distinct motions relative to each other within it [30]. ) Coronal short tau inversion recovery (STIR) image. 33 Accessibility 34 Arthroscopy remains the gold standard due to the ability to directly observe LTL tears and apply the Geissler Arthroscopic Grading System ( The wrist is not a single joint, but a complex of 20 joints with different levels of mobility, which are held together by a complex of ligaments. DRC ligament injuries are challenging to identify with standard arthrography and are best viewed on coronal T1- or T2-weighted MRI images. Fig. Check for errors and try again. The extrinsic wrist ligaments include the dorsal intercarpal (DIC) ligament, dorsal radiocarpal (DRC) ligament, radioscaphocapitate (RSC) ligament, long radiolunate (LRL) ligament, short radiolunate (SRL) ligament, ulnolunate, and ulnocapitate ligament . Braun H, Kenn W, Schneider S, Graf M, Sandstede J, Hahn D. Rofo. 64 The bones of the DCR are tightly bound to each other via strong ligaments, and they creating essentially a single functional unit [4,9]. 85. 19 Introduction. Both ligaments were found to have a high concentration of mechanoreceptors and nerve endings providing proprioceptive feedback. [15]. Due to the mobility of the PCR, the focus will be on the ligaments connecting the bones of the PCR. Fig. A The Ovoid/Cshape theory; (A) L = lunate, and Tq = triquetrum, schematic of the dorsodistal view of the midcarpal ovoid with which the scaphotrapeziotrapezoid (STT) joint is in contact; (B) S = scaphoid, separated view of the Ovoid; (C) Ovoid in 3D (modified after [50]). Mayfield J.K., Johnson R.P., Kilcoyne R.F. They described that there were no significant differences in carpal bone motion (FE and RUD) when the wrist was moved actively via the extensor and flexor tendons or passively, with a constant force applied to the tendons [45]. They can be divided into palmar, dorsal, radiocarpal, and ulnocarpal. Incongruency or step-off of carpal alignment as seen from both radiocarpal and midcarpal space. The latter is apparent with the presence of the Terry Thomas sign, disruption of carpal Gilula arcs (normal carpal alignment as viewed on PA radiographs), and the scaphoid ring sign (cortical ring appearance due to abnormal scaphoid volar flexion) with the wrist at rest ( The columnar carpus is demonstrated in Figure 5B. https://creativecommons.org/licenses/by/4.0/.

Distal end of the radius and the articular disk. ). The wrist joint is formed by an articulation between: Together, the carpal bones form a convex surface, which fits into the concave shape of the radius and articular disk. van Kooten EO, Coster E, Segers M J, Ritt M J. Make the changes yourself here! Interosseous ligament tears of the wrist: comparison of multi-detector row CT arthrography and MR imaging. Despite this, the wrist remains surprisingly stable even with multidirectional external forces. Avulsion fractures of the radial styloid contain the origin of the RSC ligament, which are treated with anatomical reduction and fixation.

The wrist is similar to a link mechanism in which the radius, the PCR, and the DCR comprise the individual links [52] (Figure 6A). Some of these ligaments are more prone to injury than . ; visualization, J.E. 2 Attenuation or hemorrhage of interosseous ligament as seen from radiocarpal space. Lee R K, Ng A W, Tong C S et al. In this article, we shall look at the anatomy of the wrist joint - its structure, neurovasculature and clinical correlations. Wrist anatomy and biomechanics. [54] (Figure 8A). In general, there is appreciable motion between the radius and the PCR, less motion between the PCR and DCR, and no motion between the DCR and the metacarpals [20]. However, the anatomical complexity of ligamentous structures of the wrist can complicate the diagnosis and treatment of these injuries. 35 The remaining 20% bears the ulnocarpal joint [2]. Ultrasonography is a promising imaging modality for injury detection in these ligaments, with the exception of the RSL ligament.

( Wrist motion is a complicated interaction of seven carpal bones excluding the pisiform which is a sesamoid bone and the forearm. 80 Would you like email updates of new search results? ). The lunate shows the least range of motion (ROM), followed by the triquetrum and scaphoid. Kamal R.N., Starr A., Akelman E. Carpal Kinematics and Kinetics. If one exists it will be found in the head of the capitate, for both FE and RUD [3,36,37,38,39]. In case of the third metacarpal flexes or extends, the DRC moves similarly [2]. The scaphoid is at particular risk of avascular necrosis after fracture because of its so-called retrograde blood supply which enters at its distal end. 22 This category only includes cookies that ensures basic functionalities and security features of the website. 54 Radiographs, CT scans and MRI are a few modalities that diagnose wrist pathologies efficiently. The extrinsic and intrinsic ligaments of the wrist are clearly demonstrated with this technique. Palmer A K. Triangular fibrocartilage complex lesions: a classification.

The DCR bones act as a functional unit. Furthermore, in this theory, the scaphoid and the triquetrum are considered independent parts of a complex carpal mechanism [22]. The PCR bones flex during global wrist flexion and extend during global wrist extension. 81 Fig. Reference article, Radiopaedia.org (Accessed on 04 Jun 2023) https://doi.org/10.53347/rID-65959. The radiocarpal joint is a synovial joint formed between the radius, its articular disc and three proximal carpal bones; the scaphoid, lunate and triquetral bones. Wrist bone motion is complex and occurs in three dimensions. believe that a PCR/ DCR row model fits the kinematic data better than the column theory of wrist motion [41]. 77.

Unable to process the form. In the human wrist, a much more pronounced difference was seen possibly reflecting differences between species or different functional requirements of the wrist ligaments (Logan et al, 1986; Mayfield and Williams, 1979). Federal government websites often end in .gov or .mil. 24 Fig. 10 Force transmission through the distal ulna: Effect of ulnar variance, lunate fossa angulation, and radial and palmar tilt of the distal radius. Moojen T.M., Snel J.G., Ritt M.J.P.F., Kauer J.M.G., Venema H.W., Bos K.E. The wrist joint (also known as the radiocarpal joint) is an articulation between the radius and the carpal bones of the hand. There are four main ligaments located at the wrist joint: Fig 2 Palmar view of the ligaments of the wrist joint. The wrist is generally described as a joint with motion between the eight individual carpal bones and between the proximal and distal rows. Scapholunate instability: Current concepts in diagnosis and management. The most clinically relevant interosseous ligaments are the scapholunate ligament (SLL) and lunotriquetral ligament (LTL). Additionally, there is a paucity of literature providing a concise yet thorough review that addresses the scope of clinically relevant wrist ligament injuries with evidence-based discussion of current diagnostic and treatment modalities. The lunate can also undergo avascular necrosis, so immediate clinicalattention to the fracture is needed. Unauthorized use of these marks is strictly prohibited. FOIA Separating the RSC and LRL ligaments is the interligamentous sulcus (space of Poirier), representing a weak spot through which perilunate dislocations occur. 39 The simulation and planning tools are used for optimizing, e.g., to decrease the resulting joint loading, to prevent the progression of pathologic changes to the wrist (e.g., osteoarthritic changes), and to increase the longevity of an endoprosthesis. Following proximal row carpectomy (PRC), the RSC ligament serves as the primary stabilizer of the wrist and must be preserved to prevent ulnar translation. The DRUL is further described as part of the TFCC below. In vivo kinematic behavior of the radio-capitate joint during wrist flexion-extension and radio-ulnar deviation. Since its description in 1981, the TFCC has been frequently imaged and treated in the context of wrist injury. 30 No incongruency of carpal alignment in midcarpal space.

Diagnosis and treatment of acute lunotriquetral ligament injuries. This manifests clinically as paraesthesia in the sensory distribution of the median nerve and weakness of thenar muscles. The carpus is supported by a ligamentous system that prevents unidirectional migration of the carpal segment [24]. Fig. 8B 12 52 This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. The extrinsic wrist ligaments are part of a confluence of wrist ligaments. Bawa P., Chalmers G.R., Jones K.E., Sgaard K., Walsh M.L. The volar group includes the radioscaphocapitate (RSC), radioscapholunate (RSL, also known as the ligament of Testut) and short and long radiolunate (SRL, LRL) ligaments. Different articles about the anatomy and function of the carpal ligaments have been published (e.g., [2,12,18,19,20,21,22,23]), recent detailed information has further elucidated the ligamentous wrist anatomy [4]. National Library of Medicine An acute wrist sprain is an injury to a ligament often due to an acute traumatic event or chronic repetitive movements. A proper understanding of the anatomy and biomechanics is essential for effective treatment, whether conservative or surgical; this applies to the wrist no less than to other parts of the human body. While arthroscopy remains the gold standard for SLL detection, particularly due to its utility in enabling visualization of SLL dynamic instability and application of the Geissler Arthroscopic Grading System ( Terminology The dorsal radiocarpal ligament is also known as 'dorsal radiolunotriquetral ligament', or 'dorsal radiotriquetral ligament'. CT arthrogram has been explored as an alternative diagnostic modality, with a recent meta-analysis suggesting that its sensitivity and specificity are statistically equivalent to that of MR arthrogram. 2022 Nov;14(11):2947-2954. doi: 10.1111/os.13428. Slutsky D J. In the literature, the wrist joint ligaments are quite variably described. 2023;90(1):22-28. This includes information that is important to understand physiological wrist kinematics, respectively, and applies them to a review of wrist joint biomechanics and load transfer. Proximal row of the carpal bones (except the pisiform).

Moojen T.M., Snel J.G., Ritt M.J.P.F., Venema H.W., Kauer J.M.G., Bos K.E. ; data curation, J.E., F.M. The simulation of such a complex joint system is challenging, complex, and thus has received little attention [1,7,8]. The extrinsic and intrinsic ligaments of the wrist are clearly demonstrated with this technique. The nearly rigid ligamentous connection of the DCR to the basis of the metacarpal bones allows considering the DCR functionally as part of a unit that moves in response to the muscle forces of the forearm [9]. Given that the sensitivity and specificity are reported as 69% and 66%, respectively, additional diagnostic modalities should be employed. 10A Since both the ulnolunate and ulnotriquetral ligaments originate from a ligament, injury or disease affecting the palmar radioulnar ligament will also result in ulnocarpal instability. Accuracy of magnetic resonance imaging of the wrist for clinically important lesions of the major interosseous ligaments and triangular fibrocartilage complex; correlation with radiocarpal arthroscopy. Tang C QY, Lai S WH, Leow G, Tay S C. Patient-reported outcome following ulnotriquetral ligament split tear repair. However, since patients usually present several months after an injury, it is not clear how to distinguish traumatic and degenerative lesions on physical examination.

The wrist joint is a highly mobile joint to allow the hand to move in several directions. Revisions: 31. Incongruency or step-off of carpal space. ) Axial proton density (PD)-weighted image. Horii E, Garcia-Elias M, An K N et al. 50 Using pressuresensitive film to define the contact area between bones in the wrist and radius, three distinct regions of contact have been identified in the radiocarpal joint: radioscaphoid, radio-lunate, and ulnolunate [2]. Berger R.A., Crowninshield R.D., Flatt A.E. Summary of the different models and theories. Overview The wrist is a complex joint that bridges the hand to the forearm. The motion of the hand to the forearm can be described via two DOF rather than the usual six DOF that have been described for the traditional kinematic analysis [32,34]. 7 Physical examination can reveal swelling and tenderness to palpation in the anatomical snuffbox and around the dorsal radiocarpal joint. Their motion behavior depends on the response of the musculotendinous forces of the forearm [9]. By Gilo1969 (Own work) [CC-BY-SA-3.0], via Wikimedia Commons, Adapted from work by Iiibalesiii [CC BY-SA 4.0], [caption id="attachment_6512" align="aligncenter" width="507"], [caption id="attachment_6513" align="aligncenter" width="700"], [caption id="attachment_10418" align="aligncenter" width="313"], [caption id="attachment_69968" align="aligncenter" width="679"]. The PCR bones come along with a unique motion pattern. Intracarpal soft-tissue lesions associated with an intra-articular fracture of the distal end of the radius. 82 This ligamentous and cartilaginous connection between the distal radius and ulna comprises multiple structures including the triangular fibrocartilage (also known as the articular disc), the DRUL and volar radioulnar ligament, and the sheath of extensor carpi ulnaris, which has questionable contribution to the TFCC. Instead, the ulna articulates with the radius just proximal to the wrist at the distal radioulnar joint. The wrist is vulnerable to axial forces and deforming vectors due to its structure and the large range of motion. Personalized modeling, biomechanical simulation, and load analysis of implants, and their boundary conditions have been advocated. Intrinsic ligament injury was present in 60%. Jakubowitz E., Kaszap B., Zhang H., Mack M., Kiggen K., Jahnke A., Daecke W. Kontaktkrfte im Radiokarpalgelenk in Abhngigkeit zur Handgelenksstellung. FE movements (sagittal plane) are evenly distributed between the radiocarpal and midcarpal joints (Figure 3). Intrinsic carpal ligaments, the tiny ligaments between the carpal bones, are short ligaments that provide stability but are easily damaged with excessive force or twisting due to their small size. The Anatomy and Basic Biomechanics of the Wrist joint. The load across the midcarpal joint is distributed at 31% through the scaphotrapeziumtrapezoid joint, 19% through the scapho-capitate joint, 29% through the lunocapitate joint, and 21% through the triquetrohamate joint [2]. The palmar extrinsic ligaments extending from the ulna exist as an ulnocarpal ligamentous complex (UCLC), containing the ulnocapitate, ulnotriquetral, and ulnolunate ligaments ( 72 Comment on Eschweiler et al. There are 20 individual ligaments of the wrist connecting the eight carpal bones to each other as well as to the forearm and the hand. The result of Taleisniks anatomy sections (17 human preparations) was a modification of the model theory of Navarro (Navarro, 1921) (Figure 5C) [22]. The ulnocapitate ligament is the most superficial, 61 The range of operative interventions includes LT arthrodesis, ligament reconstruction using a distal extensor carpi ulnaris tendon graft, and ligament repair. 4 Careers. Carpal stability depends on the integrity of both intra-articular and intracapsular carpal ligaments. ) Coronal PD-weighted image. 1 Arthroscopic repair has yielded good results in DRC ligament injuries.
