Which classification is used to describe talus injuries, especially talar neck fractures?

• A. AO/OTA
• B. Weber
• C. Salter-Harris
• D. Hawkins

Answer: (C)

Classification systems for talus injuries focus on how the fracture affects joint alignment and blood supply. For talar neck fractures, the Hawkins scheme is the standard because it ties the pattern of fracture and dislocation to prognosis and management. It ranges from a nondisplaced neck fracture to progressively more severe displacements with subtalar and then tibiotalar dislocations, and in the most advanced form, involvement of the talonavicular joint. The risk of avascular necrosis increases with higher Hawkins grades, which makes this classification clinically meaningful for treatment decisions. Salter-Harris, by contrast, describes physeal (growth plate) fracture patterns in skeletally immature bones. It’s used when a pediatric fracture involves the growth plate, not to describe the typical talar neck fracture pattern. In pediatric cases where the physis is involved, a Salter-Harris designation may be applied to reflect physeal injury, but it isn’t the primary system for describing talar neck fractures. Other classifications like AO/OTA or Weber address different bones or contexts and aren’t specifically tailored to talus neck injuries.
