Unstable Ankle Fracture Fixation Using Locked Fibular Intramedullary Nail in High-Risk Patients.

Open reduction internal fixation is the gold standard for unstable ankle fracture fixation; however, complications in patients with multiple medical comorbidities are common. Intramedullary nail fixation of the fibula can help to mitigate these difficulties. A retrospective chart review was performed on all patients who underwent fixation for unstable ankle fracture between January 2015 and March 2016 at our level I trauma center. Comorbidities in the patient sample included were one or several of diabetes, renal disease, hypertension, advanced age with osteoporosis, hemorrhagic blisters, and alcoholism. The primary outcomes studied were wound complications, infections, and hardware failure or failure of fixation. Eighteen patients with a mean age of 61 years underwent fibular intramedullary nail fixation, all of whom were considered at high risk for postoperative complications. Patients presented with Weber B or C fracture patterns. All patients had syndesmotic fixation through the nail by one or two 3.5-mm tricortical screws. A medial malleolus was added if needed for stability. The average follow-up time was 291.1 (range 9 to 14 months) days. The prescribed range of time to weightbearing was 2 to 6 weeks. All patients maintained reduction of the fracture and had no wound complications. No syndesmotic screws broke postoperatively, although most patients to failed comply with the postoperative non-weightbearing restrictions. Intramedullary nailing of the fibula with syndesmotic intranail fixation is minimally invasive, quick, and provides adequate fixation strength. It offers a viable treatment option for patients at high risk for complications or who are suspected to have difficulty with follow-up or compliance. Published by Elsevier Inc.
