The classification consists of four major groupings, based on the number of displaced parts. Radiographic F2 facet fracture with potential for instability (either superior or inferior facets). Lunate dislocations are an uncommon traumatic wrist injury that require prompt management and surgical repair. The Neer classification of proximal humeral fractures is probably the most frequently used system along with the AO classification of proximal humeral fractures. The Weber ankle fracture classification (or Danis-Weber classification) is a simple system for classification of lateral malleolar fractures, relating to the level of the fracture in relation to the ankle joint, specifically the distal tibiofibular syndesmosis. To provide users with a more streamlined, concise, and clinically relevant tool, changes to terminology and typography were made, a review of the codes with regards to frequency and applicability was conducted, paired bones (radius/ulna and tibia/fibula) are now coded individually, all fracture illustrations were newly produced, and a list of universal modifiers and qualifications was introduced.
