title: Posterior tibial tendon rupture.
abstract: A patient initially presented with pain in the instep and medial malleolar area swelling after an eversion injury. The pain was described as "fiery" and failed to resolve with conservative measures. Ankle and foot radiographs were normal. The patient returned several weeks later with complaints of continued pain and of disturbed gait, the latter due to unilateral flatfoot and a sensation of loss of control of the involved foot. At surgery an incompetent posterior tibial tendon was found and repaired.
