Abstract:
Seventeen cases of Kienbock's disease were treated since 1982, and analysed their clinical outcomes to confine the pathogenesis and to make sure the best way to treat them in various stages. It was not related to trauma around wrist joint (35.3%) but significantly closed to ulnar negative variances(64.7%). Ulnar tilt angle was increased definitely upto 28.9° compared with normal value (22°) in ulnar negative variance, but volar tilt angle was within normal limits. The packing with tensor fascia lata or palmaris longus tendon after the complete excision of avascular lunate could not prevent the collapse of carpal bones at long-term follow-up. But the triscaphe fusion was most effective to maintain the normal wrist anatomy, and radial shortening than ulnar lengtherning is thought to be more effective in wrist biomechanics of kienbock's disease with ulnar negative variances.
