Superior peroneal retinaculoplasty: a surgical technique for peroneal subluxation.

Abstract

A modification of a soft tissue reconstruction procedure for treatment of peroneal tendon subluxation and dislocation is presented. The procedure is based on creating one periosteal flap from the posterior fibula in the region of the peroneal groove. The flap is used to reinforce the superior peroneal retinaculum and prevent anterior displacement of the tendons. This reconstructive procedure has several advantages over existing procedures. The major advantage is that it recreates the normal anatomy of the superior peroneal retinaculum with little disturbance of the surrounding tissues. In addition, the procedure is simple and can be done relatively quickly for patients with acute and chronic subluxation and/or dislocation. Finally, because metallic hardware (such as screws or suture anchors) is not used, artifacts are minimized on magnetic resonance imaging scans.
