Diagnosis and Treatment of Neuropathic Ankle Fractures

Abstract

• » Standard 3-view ankle radiographs are the first-line imaging modality for suspected neuropathic ankle fractures. Computed tomography is helpful to evaluate for concomitant osseous changes and soft-tissue infection.
• » Nonoperative management may be considered for low-demand, elderly, or comorbid patients for whom surgery and anesthesia are contraindicated. However, the presence of comorbidities alone should not necessarily preclude operative intervention. Given the overall poor results of nonoperative treatment in the neuropathic ankle fracture population, operative intervention may in fact be less risky to the patient.
• » The authors have 2 preferred treatment techniques. For cases in which the vascular supply and bone stock are adequate, open reduction and internal fixation (ORIF) with locking fixation for the fibula, a medial buttress/hook plate with lag screws for the medial malleolus, multiple syndesmotic screws for additional fixation even in the absence of a syndesmotic injury, and temporary transfixation Steinmann pins from the calcaneus into the tibia are used. For cases in which there is a concern for wound healing or previously failed ORIF, minimally invasive surgical tibiotalocalcaneal arthrodesis with a retrograde locked intramedullary nail is used.
