The role of the posterior tibial muscle in producing foot deformities has been stressed in the literature. The importance of releasing the posterior tibial tendon in correcting an equinovarus deformity has been well recognized. A review of the literature, however, reveals that transplantation of the posterior tibial tendon through the interosseous space is not a well known operative procedure.
Transplantation of the posterior tibial muscle and tendon through the interosseous space is a valuable operative procedure and can be relied upon to restore active dorsiflexion of the foot. The operation is applicable to a wide variety of conditions in which the posterior tibial muscle has good power and there is a need for an additional dorsiflexor of the foot.
