摘要:

目的 研究肩胛下角的解剖形态学特点,从而探讨其解剖学意义。  方法 选取275例人体干燥肩胛骨标本,设肩胛下角为a点,盂下结节为b点,肩胛冈与肩胛骨内侧缘交点为c点,肩胛上角为e点,冈盂切迹为f点,经a点做cf连线的垂线,与cf交于d点;用游标卡尺、量角器分别测量a点厚度(以肩胛下角最厚处为准),ab、ac、ad长度,∠bac、∠ace(肩胛骨解剖学意义上矢状面投影)、∠ace′(肩胛骨解剖学意义上冠状面投影)角度。  结果 根据形态学特点发现肩胛下角分为3型:副角型(145,52.73%)、U型(87,31.64%)、V型(43,15.64%)。其中,副角型与V型在a点厚度、ab上有统计学差异(P<0.05);副角型与U型,副角型与V型在ac上有统计学差异(P<0.05);副角型与V型,U型与V型在ad上有统计学差异(P<0.05);副角型与U型在∠ace′上有统计学差异(P<0.05)。此外,左右两侧肩胛下角在∠bac上有统计学差异(P<0.05)。  结论 在本次实验中,发现肩胛下角存在三种形态学变异,以副角型为主,其解剖形态学分型具有一定的临床指导意义。

Abstract:

Objective To study the morphology of the inferior angle of scapula, and to explore its clinical significance. Methods The inferior angle of scapulae were measured in 275 dry scapular bones. Reference points: a: inferior angle; b: inferior glenoid tubercle; c: the intersection of the medial edge of the scapula and the scapular spine; e: scapular angle; f: spinoglenoid notch; d: the intersection of the line cf and the vertical line through point a. The parameters of inferior angles of 275 dry scapular bones, including the thickness of point a (the thickest part of inferior angle of the scapula), the length of the line ab, line ac, and line ad, and the angle of ∠bac, ∠ace (the projection of the scapular sagittal plane), and ∠ace′(the projection of the scapular coronal plane), were observed and measured using Vernier caliper and Goniometer. Results The morphology of the inferior angle of scapulae can be divided into 3 types, namely, Accessory angle-type (145, 52.73%), U-type (87, 31.64%) and V-type (43, 15.64%). In terms of the thickness of point a and the length of line ab, there were significant differences between the Accessory angle-type and V-type (P<0.05). With regard to the length of line ac, Accessory angle-type revealed a significant difference compared with U-type (P<0.05), or V-type (P<0.05). In terms of the length of line ad, there was a significant difference between the Accessory angle-type and V-type (P<0.05); Meanwhile, a statistical difference was found in U-type and V-type (P<0.05). With respect to ∠ace′, there was a statistical difference between Accessory angle-type and U-type (P<0.05). Besides, regarding ∠bac, the inferior angle of scapular of the right side was statistically different from that of the left side (P<0.05). Conclusion The inferior angle of scapulae have three anatomical types, with the Accessory angle-type as the main type, and the morphology and classification of it are of certain clinical implication.
