중수 수지 관절의 견열 골절에 대한 수술적 치료
The metacarpophalangeal avulsed fracture was rare and there was difficulty in diagnosing it. We evaluated 11 patients who had metacarpophalangeal avulsion fracture from May, 1996 to November, 1997. The mean age was 22.2 years and interval from initial trauma to operative treatment was 6.7 days. The involved site was index finger in two cases, middle finger in six cases and ring finger in three cases. The base of proximal phalanx was more frequently involved than head of metacarpal bone. And radial side was involved in seven cases. The shape of bony fragment were round, triangular or rectangular. We performed operative treatment in all eleven cases. We used K-wire fixation in eight cases and absorbable pin, small needle and pull out suture in one case, respectively. Postoperative immobilization was done for fourteen days. We removed the K wires in 3.9 weeks after operation. There were some complications in five cases such as limitation of motion, K wire extraction, displacement of extensor tendon and bony resorption. The postoperative results were excellent in six cases and good in four cases and poor in one case.
