This tendon transfer is only used if the extensor carpi ulnaris appears to be functional enough. Thumb surgery
The soft tissue envelope in congenital contractual conditions such as clasped or arthrogrypotic thumbs is often deficient in two planes, the thumb-index web and the flexor aspect of the thumb. There is often an appearance of increased skin at the base of the index finger that is part of the deformity. This tissue can be used to resurface the thumb-index web after a comprehensive release of all the tight structures to allow for a larger range of motion of the thumb. This technique is called the index rotation flap.The flap is taken from the radial side of the index finger. It is proximally based at the distal edge of the thumb-index web. The flap is made as wide as possible, but still small enough to close with the excessive skin on the palmar side of the index finger. The flap is rotated around the tightest part of the thumb to the metacarpophalangeal joint of the thumb, allowing for a larger range of motion. Foot surgeries
Generally, foot surgery is usually reserved for patients with a walking or ambulatory potential. Foot surgery may also be indicated to assist brace and orthosis fitting and hence promote supported standing. The most common foot deformity in arthrogryposis is club feet or talipes equinovarus. In the early years of life the serial casting according to the Ponseti method usually yields good results.
