Colles骨折与舟月骨分离

Colles Fracture with Scapholunate Dissociation

作者对38例Colles骨折合并舟月骨分离患者,采用适当延长对抗牵引时间.闭合手法复位,整复后中立位或轻度背伸位固定的治疗,经6～18个月的随访,优良率86.84%.认为舟月分离是腕不稳定的主要因素之一.治疗首先要力争使骨折解剖复位.以纠正腕关节的动力性不稳定:同时要恢复舟月骨之间正常的解剖关系,传统的掌屈尺偏位固定,不利于改善腕关节不稳定的状态.

Thirty - eight cases of colle's fracture complicated by scapholunate dissociation were treated by means of appropriately extension in time of traction, manual closed reduction and the neutral or light dorsal flexion fixation of the wrist after reduction. A following -up period lasting six to eighteen months showed that the success rate of the treatment was 86. 84%. Scapholunate dissociation is considered to be the major cause of the instability of the wrist joint. The treatment is to restortore of the anatomical relation -ship so as to correct the dynamic carpal instability. The coventional method of fixing the palmar flexion and the ulnar inclination of the wrist after reduction is adverse to the improvement of the instability of the wrist joint.
