Objective To investigate the clinical effect of distal radioulnar joint fusion combined with ulnar distal pseudoarthroplasty(modified Sauvé-Kapandji surgery)for treatment of distal radioulnar arthritis under arthroscopy.Methods The 12 patients with distal radioulnar arthritis were treated by modified Sauvé-Kapandji surgery under ar-throscopy.Distal radioulnar joint fusion,complications,pain VAS of the wrist joint and the grip strength of affected side were recorded,joint motion was measured,and wrist function was evaluated by Mayo score.Results All patients were followed up for 8～36 months.Distal radioulnar joint fusion lasted in 11～28(18.0±6.3)weeks.There was no re-ossification of osteotomy broken end,bone bridge formation.Six months after surgery,the pain VAS was decreased than before surgery(P<0.05),the wrist joint motion and forearm rotation range were improved,compared with those before surgery(P<0.05),and the grip strength of affected side was improved than the preoperation(P<0.05).At 6 months after surgery,the Mayo score of wrist joint function was 55～95(76.3±14.7)points,of which 6 cases were excellent,3 good,2 medium,and 1 poor,with an excellent-good rate of 9/12.Conclusions In the treatment of distal radioulnar arthritis,the modified Sauvé-Kapandji surgery under arthroscopy has high fusion rate,obvious pain relief and good joint function recovery.
