Interference screw fixation and short harvest using flexor digitorum longus (FDL) transfer for posterior tibial tendon dysfunction: a technique.

Posterior tibial tendon dysfunction is a common clinical entity treated by foot and ankle specialists, and numerous surgical treatments are available to the modern foot and ankle surgeon. Fixation methods are constantly evolving as new products are developed and new uses for existing products are attempted. Interference screw fixation is the gold standard fixation for tendon autograft and allograft in orthopedic sports medicine. The technique that we describe in this article uses a less extensive harvest of the flexor digitorum longus tendon and a sound fixation method using an interference screw positioned in the tarsal navicular.
