Achilles tendon contracture is a shortening of the Achilles tendon (tendon calcaneus or heel cord), which causes foot pain and strain, with limited ankle dorsiflexion. Achilles tendon contracture may reflect a congenital structural anomaly or a muscular reaction to chronic poor posture, especially in women who wear high-heeled shoes and joggers who land on the balls of their feet instead of their heels. Tenotomy allows further stretching by cutting the tendon. After surgery, a short leg cast maintains the foot in 90-degree dorsiflexion for 6 weeks.
