Ligament reconstruction with allograft of the peroneal retinaculum for repair of congenital dislocation of the peroneal tendons: description of a surgical technique

Abstract

Introduction: We describe here the rationale of a new surgical technique to repair congenital peroneal tendons dislocation or subluxation. Surgical findings showed that there is a poor development of peroneal tendons groove on the posterior aspect of the fibula as well as a lowered and distally placed peroneal miotendinous union.

Methods: The new surgical technique described here uses a bone-tendon-bone patellar allograft locked by bio-tenodesis screw at the calcaneus to reproduce the mechanical barrier that superior peroneal retinaculum offers to peroneal tendons.

Results: The procedure has initially proved a complete relief of pain, without any further dislocation of peroneal tendons in four patients. The surgery last less than an hour, the patients recovered a functional walking pattern 8 weeks after the procedure. Patients were able to run or dance 12 weeks after the procedure. No skin complications were seen in these initial four patients and a surgical removal of the bio-tenodesis screw was not necessary.

Discussion: We recommend the use of this new surgical technique as it is secure for the treatment of congenital peroneal tendons dislocation or subluxation.
