Endoscopic fibular groove deepening for stabilisation of recurrent peroneal tendons instability in a patient with open physes

摘要

This is a report of a rare case of recurrent traumatic peroneal tendon dislocation in a patient with open physes. Through fibular tendon endoscopy, an intramuscular needle was introduced under direct visualisation and implanted inferiorly to the growth plate while reclining the tendons posteriorly. A fibular groove deepening was performed in order to stabilize the tendons. The patient was able to return to full activity after 3 months. MRI taken 12 months after surgery showed neither signs of recurrence of the lesion nor growth plate disturbance. This is a first case report of peroneal tendons stabilisation by tendoscopic retro-malleolar groove deepening in a child.
