Management of Neglected Peroneal Tendon Dislocation of Iatrogenic Etiology: A Case Report

INTRODUCTION: Neglected peroneal tendon dislocation with iatrogenic etiology has been rarely reported in the literature and its management has not been fully understood to date. CASE REPORT: We present a case of a 25-year-old male who presented with pain over the posterolateral aspect of his left ankle which was diagnosed to be a case of neglected peroneal tendon dislocation of iatrogenic etiology. Peroneal groove deepening with superior retinaculum repair was done in the patient along with loose body removal and osteophyte excision. Subsequent fibrosis augmented with the deepening of the groove maintained peroneal tendon position in the retromalleolar groove. On post-operative follow-up, the patient was completely satisfied with relief of pain and no complications. He also regained full range of motion and could walk without support. CONCLUSION: Surgical intervention of fibular groove deepening with superior peroneal retinaculum reconstruction results in an excellent outcome for neglected peroneal tendon dislocation.
