## Overview Fractures of the sustentaculum tali (the medial shelf of the calcaneus that supports the deep digital flexor tendon) cause lameness and swelling on the medial hock. They can damage the tendon sheath and lead to chronic tenosynovitis. Diagnosis is by radiographs or computed tomography. ## Causes Trauma. ## Diagnosis Radiographs, often with special views or computed tomography. ## Treatment Surgical removal of fragments or stabilization when possible. Conservative management for non-displaced fractures. Prognosis is guarded because of tendon-sheath involvement. ## Recovery and Prognosis Guarded. ## Prevention Trauma avoidance.
