Endoscopic Treatment of Intrasheath Peroneal Tendon Subluxation

Abstract EN

Intrasheath subluxation of the peroneal tendons within the peroneal groove is an uncommon problem.

Open exploration combined with a peroneal groove-deepening procedure and retinacular reefing is the recommended treatment.

This extensive lateral approach needs incision of the intact superior peroneal retinaculum and repair afterwards.

We treated three patients with a painful intrasheath subluxation using an endoscopic approach.

During this tendoscopy both tendons were inspected.

The distal muscle fibers of the peroneus brevis tendon were resected in two patients.

A partial tear was debrided in the third patient.

All patients had a good result.

No wound-healing problems or other complications occurred.

Early return to work and sports was possible.

An endoscopic approach was successful in treatment of an intrasheath subluxation of the peroneal tendons.
