目的 探讨人类上胫腓关节坡度对关节本身的稳定性是否有影响。方法 采用两种方法分别对 10 9根干腓骨的上胫腓关节坡度进行测量。结果 腓骨干纵轴与关节面的夹角 (∠A)为 5 9 93°± 9 2 9° ,左右侧比较差异无显著性 (P =0 2 5 )。该角度越大 ,坡度越平坦 ;角度越小 ,坡度越陡直。关节面与水平线的夹角 (∠B)为 30 2 5°± 9 32°,左右侧比较差异无显著性 (P =0 2 5 )。该角度越大 ,坡度越陡直 ;角度越小 ,坡度则越平坦。两种方法测量结果之间呈负相关 (r =- 0 396 2 ,t =4 47,P <0 0 0 1)。结论 测量上胫腓关节坡度可了解国人上胫腓关节解剖结构和类型 ,估价上胫腓关节的稳定性 ,对上胫腓关节不稳 (半脱位 )的诊断具有参考价值。
Objective To investigate whether the gradient of the human superior tibiofibular joint has an impact on the stability of the joint itself. Methods Two methods were used to measure the inclination of the superior tibiofibular joint of 10 9 dry fibulas. Results The angle between the longitudinal axis of the fibula and the articular surface (∠A) was 59 93 ° ± 9 2 9 °. There was no significant difference between the left and right sides (P = 0 25). The larger the angle, the more flat the slope; the smaller the angle, the steeper the slope. The included angle (∠B) between the articular surface and the horizontal line was 30 2 5 ° ± 9 32 °, with no significant difference between the left and right sides (P = 0 25). The larger the angle, the steeper the slope; the smaller the angle, the more flat the slope. There was a negative correlation between the two methods (r = - 0 396 2, t = 477, P <0 0 01). Conclusions The anatomic structure and type of the superior tibiofibular joint can be obtained by measuring the slope of the superior tibiofibular joint. The stability of the superior tibiofibular joint can be assessed, which is of reference value for the diagnosis of instability (subluxation) of the superior tibiofibular joint.
