Stenosing Peroneus Brevis Tendinitis Caused by Peroneus Quartus Tendon / 대한정형외과학회잡지

ABSTRACT

Peroneus quartus tendon is one of a group of accessory peroneal tendons present in humans. Associated pathologies include an attritional tear in the peroneus tendon, stenosing tendinitis, and peroneal tendon subluxation or dislocation. A 22-year old female patient, who presented suffering with lateral ankle pain and instability after ankle sprain, visited this hospital. The physical examination and MRI indicated a longitudinal tear of peroneus brevis tendon or chronic stenosing tendinitis caused by peroneus quartus tendon. Tenosynovectomy and an excision of the peroneus quartus tendon were performed. Satisfactory results were obtained at the 1 year follow-up after surgery. Orthopedic surgeons should consider the possible presence of the peroneus quartus tendon in a differential diagnosis of chronic lateral ankle pain.
