Osteochondral fracture of the talofibular joint.
Many accounts have been written concerning osteochondral fracture of the ankle joint. However, many of these pertain only to the talus. The author discusses an osteochondral fracture of the fibular articulating surface of the ankle joint. The etiology of the osteochondral fracture, previously undescribed, is postulated to arise from a plantarflexed inverted foot that undergoes axial rotation. The talus, therefore, fractures the fibular articulating surface. These fractures may be difficult to diagnose and require special radiographic views, such as computed tomography scans or tomograms, to help differentiate the diagnosis. In some cases, ankle arthrography may be helpful in identifying the fracture.
