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.
跟骨结节骨折较为少见，多见于老年和糖尿病患者。这些损伤通常是由腓肠肌-比目鱼肌复合体同心收缩引起的撕脱性骨折。这些骨折的移位可能会使跟骨后表面的皮肤受损；因此，早期识别和处理至关重要。跟骨结节骨折的手术治疗需要复位和稳定固定移位的骨折块。当患者存在腓肠肌-比目鱼肌复合体的固有紧张时，成功的治疗还必须解决这一病理问题，以改善预后。
