Physeal fracture Salter III fracture 2025-05-03T09:32:30Z A type of physeal (Salter-Harris) fracture in which the fracture is intra-articular and extends from the physis into the epiphysis. Type III Salter-Harris fracture If the fracture extends the complete length of the physis, this type of fracture may form two epiphyseal segments. Since the epiphysis is involved, damage to the articular cartilage may occur. One example is a Tillaux fracture of the ankle, which is a fracture of the anterolateral aspect of the growth plate and epiphysis.
