Limited wrist arthrodesis had been used to treat serious pathological condition. To evaluate the utility of limited wrist arthrodesis, nine wrists of nine patients, seven men and two women, who had received this procedure for Kienböck's disease (6 wrists), osteoarthritis (2 wrists), and pseudo-arthrosis of scaphoid (1 wrist) were followed-up.Age at operation ranged from 18 to 61 years (average; 41.6 years). Follow-up period ranged from 10 months to 24 years and 6 month (average; 8 years). The site of arthrodesis was the midcarpal joint in 4 wrists, scapho-trapezium-trapezoid (STT) fusion in 2, radio-lunate (RL) fusion in one, radio-scaphoid (RS) fusion in one, and radio-scapho-lunate (RSL) fusion in one.Roentgenographic and clinical results were evaluated by Bolano's method postoperatively.Over-all postoperative results were excellent in 2 wrists, very good in 6, good in one, fair and poor in no wrists. Postoperative range of flexion and extension with midcarpal arthrodesis was larger than that of radiocarpal arthrodesis. None of the 9 wrists had osteoarthritic changes in the surrounding joints.Limited arthrodesis is a useful procecdure for relieving pain and improving wrist function, even though the range of wrist is limited.
