The Cause

The exact cause of Arthrogryposis cannot be identified in most cases.
However, any progress which limits movement during development of the foetus in the womb may lead to congenital contractures. Potential causes of limited movement in the womb are abnormal muscle or nerve function, abnormal tissue around the joints or limitation of the space within the womb. The earlier any one of these processes occurs, the more severe the contractures will be. More than one of these factors may be operating in any individual child.
In the classical form of Arthrogryposis ( Arthrogryposis Multiplex Congenita ) no specific cause has been identified.

Treatment

The aim of treatment for children with Arthrogryposis is to help the child gain the maximum function and independence possible. Treatment should start early to ensure maximum use of any muscle activity that is present. In spite of the marked weakness of the limbs, with experienced management, most children achieve a remarkable degree of both mobility and independence, and will attend normal schools.
