Reconstruction of a missing or insufficient distal fibula in the setting of a total ankle replacement: The Milanese technique.

BACKGROUND: The presence of an intact distal fibula is reported as a prerequisite when considering total ankle replacement and its lack is usually considered a contraindication. The purpose of the study was to describe the results of a surgical technique to reconstruct the distal fibula (Milanese fibular reconstruction technique) in the setting of a total ankle replacement and insufficient fibula. METHODS: Retrospective analysis of 15 patients (15 ankles) who underwent rotational fibular reconstruction technique with minimum follow-up of 24 months. Patients were evaluated preoperatively and at the last follow-up with AOFAS Ankle and Hindfoot score, VAS pain scale, SF-12 and range of motion. Standard weightbearing radiographs were used for radiographic assessment. RESULTS: The average of all clinical scores significantly improved (P<.001). The average radiographic parameters showed a neutral alignment. No cases of reabsorption of the new lateral malleolus were observed even in cases with complications that accounted for 2 superficial wound infection and 2 deep infections. CONCLUSIONS: The Milanese fibular reconstruction technique can successfully reestablish a lateral strut and in the setting of an ankle prosthesis in patients with an insufficient fibula.
