Posterior tibial tendon rupture


One of the most common causes for a flat foot in the adult.

Along with other supportive ligaments, is responsible for maintaining the arch of the foot.

Passes behind the ankle and winds around the medial malleolus.

Individuals prone to developing a rupture include women who are overweight and people who have a flat foot that has been present since early adulthood or even childhood.

In these situations the tendon may be prone to stretch out and tear losing its supportive function, with pain and inward rolling and the deveopment of a flat foot.

As the tendon tears, its supportive function is lost and his causes pain as the foot begins to roll inward and get flat.

With flattening of the foot, other supporting ligaments stretch, tear with increasing flatness of the foot.

Pain, is associated with inflammation of the tendon and develops on the inside of the foot, just behind the ankle.

Treatment of this condition begins with support of the foot with shoe modifications, orthotic arch support and a brace that is custom molded to the ankle.

Surgical treatment for the adult’s flat foot deformity is divided into three types: 1) tendons are repaired or transf2242ed 2) bones are cut or realigned and 3) joints are fused together.

It is not possible to repair the torn posterior tibial tendon, since it will quickly stretch out and tear again.

The tendon transfer uses a tendon from behind the back of the ankle, but which is not a critical tendon.

The tendon transfer is combined with a calcaneal osteotomy.
