摘要:

文题释义:
髋关节撞击症:股骨头和髋臼间解剖的异常可引起股骨近端与髋臼间长期反复不正常的接触、碰撞,导致关节软骨及盂唇蜕变,从而引起髋关节疼痛及屈曲内收受限等一系列临床表现。
髂前下棘撞击:是髋关节外撞击最常见的类型之一,有些学者将髂前下棘撞击也称为棘下撞击,从定义上来说前者为髂前下棘突出或异常形态造成其与股骨近端的异常接触,后者主要是指髂前下棘基底部至髋臼边缘(即棘下区域)的异常骨性隆起,其实这是两种不同的病理状态,但两者经常并存。

背景:低位髂前下棘引起的棘下撞击常易被忽略,而造成部分患者漏诊或治疗效果不佳。
目的:对比分析髂前下棘撞击与无撞击患者的髋关节影像学差异,探讨常规X射线片及CT检查能否直接或间接判断低位髂前下棘的存在。
方法:选择2016年1月至2019年6月在锦州医科大学附属第一医院诊断为髂前下棘撞击并行髋关节镜手术的患者15例,作为试验组;选择行标准骨盆前后位X射线片及骨盆三维CT检查的非髂前下棘撞击患者15例,作为对照组。通过X射线片与CT检查比较两组患者α角、髋关节中心边缘角、Tönnis角、颈干角、髋臼前倾角,以及髂前下棘与髋臼前缘的水平和垂直距离及髂前下棘宽度。使用有限元分析模拟髂前下棘患者的髋关节生理活动,观察局部有无应压力变化。
结果与结论:①试验组患者的髋关节中心边缘角及髂前下棘与髋臼前缘的垂直距离测量值均小于对照组,但仅髂前下棘与髋臼前缘的垂直距离测量值存在统计学差异(P < 0.05);试验组患者的其他指标测量值均稍大于对照组,但差异无显著性意义(P > 0.05);②髂前下棘撞击的三维重建可见髂前下棘呈增生、肥大,向下延伸,但未突出至髋臼前缘,髂前下棘间隙消失,且髂前下棘突出的肥大增生部分在整个运动加载过程中与股骨近端未出现明显的接触表现;③不能通过X射线片及CT平扫推测或判断是否存在低位髂前下棘,对于低位髂前下棘的影像学诊断目前仍主要依赖于三维重建;髂前下棘撞击患者可能不存在髂前下棘肥大增生的远端与股骨近端的异常接触。

Abstract: BACKGROUND: Subspine impingement caused by low anterior inferior iliac spine is often neglected, resulting in missed diagnosis or poor treatment effect in some patients.  
OBJECTIVE: To compare and analyze the difference of hip joint of patients with anterior inferior iliac spine impingement and those without impingent, to investigate whether conventional X-ray and CT examination can directly or indirectly judge the existence of the low anterior inferior iliac spine.
METHODS:  Totally 15 patients diagnosed with anterior inferior iliac spine impingement and undergoing hip arthroscopic surgery in First Affiliated Hospital of Jinzhou Medical University from January 2016 to June 2019 were selected as trial group. Fifteen patients with non-iliac anterior inferior iliac spine impingement who underwent standard anteroposterior pelvic X-ray and three-dimensional CT examination of the pelvis were selected as control group. The angle α, the center-edge angle of the hip joint, the Tönnis angle, the neck shaft angle, the anteversion angle of the acetabulum, and the horizontal and vertical distance between the anterior inferior iliac spine and the acetabular anterior edge, and the width of the anterior inferior iliac spine were compared between the two groups using X-ray film and CT examination. Finite element analysis was used to simulate the physiological activities of the hip joint in patients with anterior inferior iliac spine, and to observe the absence and presence of local pressure change.  
RESULTS AND CONCLUSION: (1) The center-edge angle and the vertical distance of the anterior inferior iliac spine from the acetabular anterior edge of the trial group were smaller than those of the control group, but only the difference of vertical distance value between the groups was statistically significant (P < 0.05). The measured values of other indicators of the patients were slightly greater in the trial group than those in the control group, but the difference was not significant (P > 0.05). (2) Three-dimensional reconstruction of type II anterior inferior spinal impingement showed that anterior inferior iliac spine was proliferative, hypertrophic, and extends downward, but did not protrude to the acetabular anterior edge. The anterior inferior iliac spine gap disappeared. Moreover, the protruding hypertrophic part of the anterior inferior iliac spine did not make obvious contact with the proximal femur during the entire exercise loading process. (3) It is not possible to infer or judge whether there is a low anterior inferior iliac spine through X-ray and CT scans. The imaging diagnosis of the low anterior inferior iliac spine still mainly depends on three-dimensional reconstruction. Patients with anterior inferior iliac spine may not have abnormal contact between the distal end of the anterior inferior iliac spine hypertrophy and the proximal femur.
