Recurrent dislocation of the peroneal tendon.

Abstract

Recurrent dislocation of the peroneal tendons is an important, although infrequent, cause of disability of the ankle. We used a simple procedure that corrects the basic deformity of a shallow peroneal groove, without the use of metallic fixation or transfer of a tendon or ligament. The groove for the tendons is deepened by removal of some inner fibular substance, while the smooth tenosynovial channel is maintained as an intact periosteal flap on the fibula. The technique was used successfully in ten cases.
