Surgical Correction of Rigid Equinovarus Contracture Utilizing Extensive Soft Tissue Release.

Although deforming contractures of the lower extremities after acute cerebrovascular events are well documented in the literature, there is limited literature regarding specific surgical considerations for the correction of these deformities, which are nonosseus in nature. The equinovarus foot, regardless of its origin, is a challenging pathologic condition for the foot and ankle surgeon. It is critical to have a firm understanding of the cause and symptoms behind an equinovarus deformity before treatment.

Posterior Tibial Tendon Transfer.

When performed correctly with the right patient population, a tibialis posterior muscle/tendon transfer is an effective procedure. Many different methods have been established for fixating the tendon, each of which has its' own indications. Passing through the interosseous membrane is the preferred and recommended method and should be used unless this is not possible.

Principles and Biomechanical Considerations of Tendon Transfers.

Whether performed as a primary procedure or used to augment and support osseous reconstruction, tendon transfers are a key skill for the foot and ankle surgeon. Understanding the biomechanics preoperative and postoperatively is essential in performing appropriate procedures and in supporting patients through the rehabilitation process. Often the complexity of tendon transfer surgery is lost because it is deemed a soft tissue procedure and in theory should be less complex than osseous procedures.
