Focal bone lysis and periosteal reaction typical of osteomyelitis were not appreciated. Clipboard, Search History, and several other advanced features are temporarily unavailable. The Sanders classification system is used to assess intraarticular calcaneal fractures, which are those involving the posterior facet of the calcaneus. CT shows a fracture of the posterior calcaneal tuberosity with avulsion of the Achilles tendon insertion, extraarticular and without involvement of the posterior subtalar joint. Heterogeneous echogenicity of the distal achilles tendon and tendinosis / partial tearing of the distal achilles tendon are seen near the calcaneal attachment. For a full list of available versions, see the Directory of published versions . Radiographics. If it is not reduced accurately, weakness from Achilles tendon dysfunction will occur.

Even if there's an initial obvious fracture, evaluate: On lateral radiographs, two angles are helpful in indicating a calcaneal fracture even when the fracture is not clearly visible: Bohler's angle is normally 25 to 40. Fractures of the tu-berosity are either from an avulsion or shear-compression mechanism of injury, with the latter constituting most fractures. Primary fracture line is through the posterior facet (uncommonly it can be anterior or middle) Three- a) sustentacular fragment (constant) Complete avulsion fracture of the calcaneal tuberosity with very thin osseous fragment resulting in proximal retraction of the achilles tendon from calcaneal attachment.
