不同年龄段髂前下棘的解剖学特点分析

Anatomical characteristics of the anterior inferior iliac spine at different ages

目的比较18~40,41~60,≥61岁不同年龄段髂前下棘形态学解剖参数变化。方法选择正常半骨盆资料155例,其中男性115例,年龄(48±15)岁,女性40例,年龄(53±14)岁,均无髋臼撞击综合征,通过软件测量髂前下棘的最大长度、宽度、高度以及表面积和体积。结果41~60岁及≥61岁年龄段男性髂前下棘的最大宽度[(12.0±1.9)mm;(12.0±1.8)mm]、表面积[(444.11±139.24)mm^(2);(469.03±132.26)mm^(2)]以及体积[(910.19±452.34)mm^(3);(989.09±442.99)mm^(3)]显著大于女性[宽度:(9.5±1.1)mm,(9.5±1.6)mm;表面积:(328.96±92.64)mm^(2),(326.26±118.32)mm^(2);体积:(577.04±259.51)mm^(3),(482.47±254.34)mm^(3),均P<0.05)。≥61岁年龄段中,男性髂前下棘的最大高度大于女性[(6.1±1.4)mm VS(4.6±1.4)mm,P=0.007)。不同年龄段之间(18~40岁,41~60岁,≥61岁),男性和女性的解剖学参数均无统计学意义。在三个年龄段中,最常见的髂前下棘分型均是1型(18~40岁,86.05%;41~60岁,71.23%;≥61岁,79%)。年龄与髂前下棘的长度、宽度、高度、体积和表面积均没有相关性(均P>0.05)。结论髂前下棘的解剖形态相对稳定,与年龄没有显著相关性,但同年龄组不同性别髂前下棘的体积和表面积会有显著差异。此外低位髂前下棘(2型)并不一定导致髋臼撞击综合征的出现。

Objective To compare the anatomical parameters about anterior inferior iliac spine at different ages(18-40,41-60,≥61).Methods 155 normal subjects(male,115;female,40)were enrolled,and the maximum length,width,height,surface area and volume were all measured and compared.Results The maximum width(41-60 years,12.0±1.9 VS 9.5±1.1 mm;≥61 years,12.0±1.8 VS 9.5±1.6 mm),sur-face area(41-60 years,444.11±139.24 VS 328.96±92.64 mm^(2);≥61 years,469.03±132.26 VS 326.26±118.32 mm^(2))and volume of the anterior inferior iliac spine(41-60,910.19±452.34 VS 577.04±259.51 mm^(3);≥61 years,989.09±442.99 VS 482.47±254.34 mm^(3))in males(41-60,≥61 years old respectively)were sig-nificantly higher than those in females at the same age group,and the differences were significant(P<0.001).In the age group≥61 years,the maximum height was also statistically significant in males and females(P=0.007).Anatomical parameters compared in different age groups(18-40,41-60,≥61 years old)were not sta-tistically significant in men and women.The most commonly observed type of anterior inferior iliac spine was Type 1 in all three male or female ages.Conclusions The morphology of the anterior inferior iliac spine is relatively stable and has no significant correlation with age,but the volume and surface area are sig-nificantly different in the same age group with different genders.In addition,the low anterior inferior iliac spine(Type 2)does not necessarily lead to acetabular impingement syndrome in normal people.
