Description
Chronic rupture of both tendons of the peroneus longus and brevis is rare. Thus, it is difficult to diagnose and often overlooked. Since the peroneal tendons are the primary evertors of the foot and function as lateral ankle stabilizers, their rupture results in ankle sprain. We present a case with dynamic supination deformity during ambulation and hindfoot varus induced by chronic rupture of both tendons of the peroneus longus and brevis. We treated the patient with split anterior tibial tendon transfer and Dwyer calcaneal osteotomy. The dynamic supination deformity during ambulation and the hindfoot varus were improved, but a dorsal bunion remained, which was suggestive of residual dysfunction of the tendon of the peroneus longus.
