[Ligament reconstruction for lunotriquetral instability using a distally based strip of the extensor carpi ulnaris tendon]

Stabilization of the lunotriquetral junction.Dynamic and static chronic instability without fixed dislocation of the carpals.Chronically fixed dislocation of the carpals, ulnar impaction syndrome, osteoarthritis of the joint between hamate and triquetrum and other parts of the wrist joint, rheumatoid arthritis, chondrocalcinosis.Restoration of the palmar portion of the lunotriquetral ligament using a distally based strip of the extensor carpi ulnaris tendon with temporary fixation of the lunotriquetral junction with K-wires.Immobilization for 8 weeks with a radial cast that includes the first metacarpophalangeal joint. Removal of the K-wires after 8 weeks and exercise.The procedure with rare complications reliably restores stability of the lunotriquetral junction. Reduction of grip strength, pain during exercise, and a reduced range of motion persist. Overall, the results are predominantly good and excellent.
