title: Anatomy of second muscular layer of the foot: considerations for tendon selection in transfer for Achilles and posterior tibial tendon reconstruction.
abstract: Controversy exists regarding tendon choice to substitute for a ruptured posterior tibial tendon. A similar debate about late Achilles tendon reconstruction also persists. To establish priorities and aid the surgeon's decision-making process, we studied 85 en bloc dissections of the second muscular layer of the sole. Muscular and tendinous interconnections were evaluated. Location and minimal donor deficit following harvest of the flexor digitorum longus make it the transfer of choice for posterior tibial tendon reconstruction. We suggest that relative strength, anatomic location, and available length of tendon make the flexor hallucis longus the superior choice for late Achilles tendon reconstruction.
