A case of stenosing peroneal tendovaginitis.

At the foot and ankle, stenosing peroneal tendovaginitis has only rarely been described in literature. The superior and inferior peroneal retinacula, however, may cause symptoms of stenosis similar to other tendons in the foot and the hand. A case of a forty-three year-old woman is presented, where posttraumatic stenosing peroneal tendovaginitis caused sudden pain on supination of the foot. Nodular tendon swelling was present on a preoperative CT-scan. The condition was treated successfully by transsection of the peroneal retinacula.
