Addressing stage II posterior tibial tendon dysfunction: biomechanically repairing the osseous structures without the need of performing the flexor digitorum longus transfer

Abstract

The clinical presentation of adult flatfoot can range from a flexible deformity with normal joint integrity to a rigid, arthritic flat foot. Debate still exists regarding the surgical management of stage II deformities, especially in the presence of medial column instability. This article reviews and discusses various surgical options for the correction of stage II flatfoot reconstructive procedures. The authors discuss their opinion that is not always necessary to transfer the flexor digitorum longus tendon to provide relief and stability in this patient population. The anatomy, diagnosis, and current treatments of flexible flatfoot deformity are discussed.
