A scissoring deformity of the fingers frequently results from malunion of a phalangeal or metacarpal fracture. If union occurs with rotation, the injured digit will scissor with an adjacent digit on flexion of the hand. Malrotation can be corrected by a technique of step osteotomy of the metacarpal with removal of a longitudinal strip of bone. The placement of the transverse cuts of the osteotomy determines the direction of rotational correction and the width of dorsal strut determines the amount of rotational correction. Firm fixation with two interosseous wires ensures good bony union and allows early mobilization.
手指交叉畸形常因指骨或掌骨骨折愈合不良所致。如果骨折愈合伴有旋转,手部屈曲时受伤手指会与相邻手指交叉。可采用掌骨阶梯截骨术并去除一条纵向骨条的技术来纠正旋转畸形。截骨横向切口的位置决定旋转矫正方向,背侧支柱的宽度决定旋转矫正量。用两根骨间钢丝牢固固定可确保良好的骨愈合并允许早期活动。
