Combined rupture of the anterior tibial and posterior tibial tendons: a new clinical entity.

Two patients with combined rupture of the anterior tibial tendon and posterior tibial tendon are described. Both were elderly women with a gradually progressive valgus deformity of the ankle/hindfoot and severe pain. Arthrodesis procedures were performed in both patients; however, postoperative complications prevented significant clinical improvement. This combined tendon rupture is presented to document a new clinical entity.
