旋前方肌骨膜瓣移位治疗陈旧性下尺桡关节背侧半脱位

TREATMENT OF OLD DORSAL SUBLUXATION OF THE INFERIOR RADIO-ULNAR JOINT BY TRANSFER OF PRONATOR QUADRATUS MUSCLE FLAP

在解剖学研究的基础上,设计在尺骨下端背侧纵形切开尺骨骨膜,形成旋前方肌骨膜瓣,并将其移位,从掌侧向背侧穿越相对应的尺骨桡侧缘骨膜下隧道,绕尺骨下端在掌侧与该肌及坚轫的骨问膜重叠后缝合,用以使下尺桡关节背侧半脱位复位后达到稳定。经应用于临床获得了满意的疗效。

Based on the anatomical studies, the authors had designed an operation for treating old dorsal subluxation of the inferior radio-ulnar joint.The periosteum was longitudinally incised at the dorsal side of the lower ulna. forming musculo-periosteal flap, and a periosteal flap, and a periosteal valves of pronator quadratus. They were subluxation, passing the flap from palmar to the dorsal side through thc subperiosteal tunnel at the lateral margin of the radius corresponding to the ulna. Then it was circled round the lower end on the ulna and sutured to the muscular flap and the tough interosseous membranes at the palmar side, being used to stabilize the recuperated dorsal subluxation of the inferior radio-ulnar joint. The result of its clinical use was satisfying.
