摘要
目的 了解国人的月骨形态 ,为月骨假体的制作提供依据。方法 采用标准 X线摄片技术 ,对 10 0例 (左右各 5 0例 )拍摄腕关节侧位片 ,并测量 X线片上月骨的宽、高、凹面跨度及凹面曲线。结果 国人的月骨可分为 3种类型 ,其凹面曲线方程分别是 y=- 0 .0 5 8x2 +0 .95 6 9x+0 .10 89,y=- 0 .0 76 5 x2 +1.15 99x +0 .0 6 0 2 ,y =- 0 .0 919x2 +1.2 813x +0 .0 938。按此结果用硅橡胶制作出 3种大小的月骨假体 ,用于治疗 11例月骨无菌性坏死 ,术后平均随访 5 2个月 ,优良率达 10 0 % ,疗效满意。结论 利用月骨的宽、高、凹面跨度及凹面曲线来表示月骨的形态 。
Objective To observe the morphology of the lunate bone in Chinese population and provide parameters for production of lunate prosthesis. Methods Lateral projection X ray films of the wrist were taken in 100 individuals (50 of the left wrist and 50 of the right). The height, width, concave distance were measured and the concave formula was calculated. Results The shape of the lunate bone in Chinese population can be divided into three types, the concave formula of which are y = -0 058x 2 + 0 9569x + 0 1089, y = -0 0765x 2 + 1 1599x + 0 0602, y = -0 0919x 2 + 1 2813x + 0 0938 According to the results, three types of lunate prosthesis were designed and produced 11 cases of Kienbock's disease were treated by implantation of the silicone rubber prosthesis 100 % satisfactory rate was observed after an average of 52 months' follow up Conclusions The shape of the lunate bone is characterized by its width,height,concave distance and concave formula. Modeling of the lunate prosthesis should be in accordance with these parameters.
