Distal radius fracture is one of the most common fracture of upper extremities including Colles' fracture. Since 1913, classic Darrach's technique which performed excision of the distal end of the ulna for distal radioulnar arthrosis have been introduced, many procedures have been described for the surgical management of painful disorders of the distal radioulnar joint. In 1936, Sauve and Kapandji first described the procedure that included an arthrodesis across the distal radioulnar joint and created a pseudarthrosis of the ulna, proximal to the fusion, to restore pronation and supination. The purpose of the present study is to evaluate clinical results of treatment for malunited Colles' fracture using modified Sauve-Kapandji procedure as an alternative salvage operation. From 1994 May, total nine patients were evaluated, average follow-up was twenty one months. There were four male patients and five female patients. Radiographic measurement, pain of radiocarpal and radioulnar joint, range of motion of the wrist, grip strength, instability of the distal radioulnar joint were foci of this present study. We used modified Sauve-Kapandji procedure. The purpose of modification is to preserve the pseudoarthrosis and stabilize the ulna, proximal ulnar stump was stabilized with a strip of flexor carpi ulnaris and pronator quadratus was sutured to sheath of extensor carpi ulnaris. According to Fernandez Point-Score System, results showed excellent 6, good 2 and fair 1. But two patients complained continuous pain at vigorous range of motion. All of the patient showed improvment of arc of motion and rotation, especially pronation-supination and did not develop any instability. But radiographic measurement was not correlated with clinical symptoms. In conclusion, modified Sauve-Kapandji procedure is effective procedure for treatment of the malunited Colles' fracture which have severe distal radioulnar disruption, ligament laxity, subluxation of the ulna, and ulnocarpal impingement. We should consider as alternative salvage operation options of maIunited Colles fracture.
