摘要
通过腕关节解剖和电视Ｘ线动态测量桡腕、月头关节伸屈活动，证实掌侧或背侧Ｂａｒｔｏｎ骨折脱位发病机理分别为腕部处于过伸位或过屈位受伤时，月骨对桡骨远端关节面掌侧缘或背侧缘撞击所致。掌侧型应归为Ｃｏｌｅｓ骨折之特殊类型。楔形骨折块大小、是否粉碎、脱位程度和是否腕骨骨折决定其治疗方法。保守治疗复位及固定与受伤方向相反。手术治疗掌侧型用支持钢板，背侧型用克氏针固定。作者报道一组患者２１例，保守治疗１１例，手术１０例。结果为优１６例，良４例，差１例。
The movement of radiocarpal joint and midcarpal joint were measured dynamically under the supervision of “C-Arm” image intensifier. The authors found that the cause of volar or dorsal Barton's fracture dislocation was the impact of the os lunatum against anterior or posterior margin of the distal radius in overextension or overflexion of the radiocarpal joint. Volar Barton's fracture dislocation might be a special type of Colles' fractures.The treatment depends on the size of the wedge shaped fragment, its comminution,the degree of dislocation and involvement of the carpale. Twenty one cases were reviewed. Of those,10 cases were treated operatively. In the cases of volar Barton's fracture dislocation, buttress plates were used to maintain the reduction, in the cases of dorsal Barton's fracture dislocation, Kirschner wires were used.The others were treated with closed reduction and plaster immobilization. The results were excellent in 16, good in 4 and poor in 1.
