Management of calcaneal tuberosity fractures.

Fractures of the calcaneal tuberosity are relatively uncommon and are seen most frequently in elderly and diabetic patients. These injuries are typically avulsion fractures caused by concentric contraction of the gastrocnemius-soleus muscle complex. Displacement of these fractures can compromise the skin over the posterior aspect of the heel; therefore, early recognition and management are imperative. Surgical management of calcaneal tuberosity fractures requires reduction and stable fixation of the displaced fragment. When the patient has preexisting tightness of the gastrocnemius-soleus complex, successful management must also address this pathology to improve outcome.
