目的 提供详尽的肱骨结节间沟形态资料。方法 使用不同地区肱骨 80只 ,将结节间沟分为近侧水平段和远侧垂直段 ,用量角器和卡尺测量二段的长度及其移行处的角度 ;结节间沟的深度和宽度分五个部位测量 ;观察结节间沟的变异和异常。结果 结节间沟近侧段和远侧段的长度及移行处角度分别为 9.4mm、2 9.7mm和 119.9° ;总长度、深度和宽度分别为 39.2mm、0 .7mm和 2 .6mm ;结节上嵴出现率为 11.2 % ,内、外侧骨刺 16 .2 % ,钙化 45 %。结论 肱骨结节间沟的局部形态与肱二头肌长头腱损伤关系密切。
Objective To provide detailed humeral nodular groove morphology data. Methods Using 80 humerus in different regions, the nodular groove was divided into proximal horizontal section and distal vertical section. The length of the second section and the angle of the second section were measured with a protractor and a caliper. The depth and width of the inter-nodular groove Five parts of the measurement; observed nodular groove variation and abnormalities. Results The length of the proximal and distal segments of nodules was 9.4mm, 9.79 and 119.9 °, respectively. The total length, depth and width were 39.2mm, 0.7mm and 2.6mm respectively. Festival on the ridge incidence of 11.2%, inside and outside spur 16.2%, calcification 45%. Conclusion The local morphology of humeral nodules is closely related to the injury of long biceps tendon.
