v4.1 Fusion X
Sanders classification: based on CT coronal posterior facet fractures. Essex-Lopresti: tongue vs joint depression patterns. Operative indications: displacement >2 mm, malalignment, large fragment involvement. ORIF via extensile lateral or sinus tarsi approach; primary subtalar fusion in severe comminution. Complications: wound breakdown, infection, subtalar arthritis.
