摘要
目的 分析无症状青少年中股骨髋臼撞击形态征象发生率,并评估其具有股骨髋臼撞击形态征象的骨骼成熟程度.方法 回顾性分析 2016-2021年于我院急诊科就诊并行盆腔CT扫描的 136例青少年的临床和影像资料.测量阿尔法角(AA)和中心-边缘角(CEA),评估髋臼Y形软骨和股骨近端骨骺的生理状态(开放或闭合).结果 136例患者中 37 例(27.2%)为凸轮型形态,25 例(18.4%)为钳夹型形态,5 例(3.7%)为混合型形态,69 例(50.7%)为正常形态.凸轮型形态在男性中(32.9%)较女性中(21.2%)比例高,钳夹型形态在女性中(22.7%)较男性中(14.3%)比例高,但性别间不同形态征象差异无统计学意义(P＞0.05);性别间AA角差异有统计学意义(P<0.05),男性AA较女性偏大;性别间CEA角差异无统计学意义(P＞0.05).凸轮形态多见于前上象限.各组间股骨近端骨骺及髋臼Y形软骨所属成熟状态差异无统计学意义(P＞0.05).结论 股骨髋臼撞击形态征象在无症状青少年中并不罕见,多见于股骨近端骨骺开放和髋臼Y形软骨闭合状态,且凸轮型形态多见于前上象限.
Abstract
Objective To analyze the incidence of morphological signs of femoroacetabular impingement in asymptomatic adolescents and to assess skeletal maturity in adolescents with morphological signs of femoroacetabular impingement.Methods The clinical and imaging data of 136 adolescents with pelvic CT scans during 2016-2021 in the emergency department were analyzed retrospectively.The Alpha angle and the central edge angle were measured and the physiologic status of the acetabular Y-shaped cartilage and proximal femoral epiphysis(open or closed)were assessed.Results Of the 136 patients,37 cases(27.2%)had a cam-type morphology,25 cases(18.4%)had a clamp-type morphology,5 cases(3.7%)had a mixed morphology,and 69 cases(50.7%)had a normal morphology.The proportion of cam morphology was higher in males(32.9%)than that in females(21.2%),and the proportion of clamp morphology in females(22.7%)was higher than that in males(14.3%),but there was no statistical difference in different morphological signs between genders(P＞0.05).AA angle had a statistical difference between genders(P<0.05),AA of male was larger than female;CEA angle had no statistical difference between genders(P＞0.05).The cam-type was more common in the anterior upper quadrant.There was no significant difference in the maturity status of the proximal femoral epiphysis and acetabular Y-shaped cartilage among the groups(P＞0.05).Con-clusion Femoroacetabular impingement is not uncommon in asymptomatic adolescents.It is usually found in the open proximal femoral epiphysis and closed acetabular Y-shaped cartilage.The cam shape is often seen in the front and upper quadrants.
