HIGH-RESOLUTION US OF NONTRAUMATIC RECURRENT DISLOCATION OF THE PERONEAL TENDONS - A CASE-REPORT

We report the case of a young girl with recurrent sharp pain in the ou ter aspect of the ankle. She had no previous trauma. High-resolution U S (HRUS) showed a complete intermittent dislocation of the peroneal te ndons. Post-traumatic chronic peroneal instability is quite common, wh ereas complete dislocation is rare. HRUS is an important adjunct to cl inical examination and radiographic evaluation of patients with muscul oskeletal disorders of the foot and ankle [1]. This paper reports its value in non-traumatic recurrent dislocation of the peroneal tendons.
