Detailed Description

Radial club hand is a deficiency along the radial side of the extremity. Although considerable forearm and hand anomalies are the classic findings, proximal deficiencies also can occur throughout the arm and shoulder girdle. The elbow abnormalities can include deficiences of the olecranon, capitellum, coronoid fossa, and medial epicondyle.

In 1733, Petit first described radial club hand in an autopsy of a neonate with bilateral club hands and absent radii.

Initial surgical treatment of radial club hand involved an ulnar osteotomy to correct the bow, along with splitting of the distal ulna for insertion of the carpus. Reconstruction of the radius with a bone graft to support the carpus was reported in the 1920s, and non-vascularized epiphyseal transfer was reported in 1945. Results of these procedures were disappointing. They had multiple causes of failure, including disruption of the ulnar growth plate and subsequent increase in limb-length discrepancy, inadvertent ankylosis or arthrodesis of the wrist and loss of motion, and failure of the transplanted bone to grow, with eventual loss of radial support.

Centralization of the carpus on the distal ulna has emerged as the preferred surgical technique for correcting radial clubhand.in 1893, Sayre described it consisting of seating the distal ulna into a surgically created carpal notch. Pioneers in congenital hand surgery developed the basis for this procedure. Numerous modifications have been described to obtain or maintain correction of the wrist on the ulna.

Wrist centralization involves aligning the distal ulna with the middle finger metacarpal and passing a large Kirschner wire or a a small Steinmann pin through the middle finger metacarpal , carpus ,and ulna for temporary stability. This is followed by soft tissue balancing in order to counteract the volar and radial directed force vectors consisting of reefing the ulnocarpal wrist capsule and transferring the extensor carpi ulnaris muscle distally and flexor carpi ulnaris muscle dorsally on the wrist.
