摘要

背景:髋关节的关节囊韧带与髋臼和股骨头同步工作,以保证关节的稳定性。目的:评估非关节炎成人髋关节中 ISFL 的插入情况:对72名接受磁共振关节造影(MRA)评估髋关节疼痛的患者进行了回顾性分析。同时使用轴向斜位、冠状位和矢状位 MRA 图像评估了 ISFL 成分的分布、厚度和插入部位:在71个(99%)髋关节中发现了股骨头中心前方的两个ISFL插入点:(i) 主要在前方与髂股韧带合并,作为眼轮匝肌带的延续,在所有髋关节中均可观察到;(ii) 股骨颈和大转子的前外侧交界处。在研究的 72 个髋关节中,有 70 个(97%)发现了 ISFL 的两个部分(近端和远端)。近端部分总是较薄(平均 2.6 ± 0.7 毫米),源自髋臼边缘的楔骨。远端部分是眼轮匝肌的延续,平均厚度为 6.7 ± 1.6 毫米。两部分在经过股骨头上部时合并:结论:股骨峡韧带的主要插入部位是在前方与髂股韧带合并。涉及ISFL的髋关节镜等外科手术会影响髂股韧带的功能,反之亦然。

The predominant insertion of the ischiofemoral ligament is a merging to the iliofemoral ligament as demonstrated on magnetic resonance arthrogram studies.

Background: The capsular ligaments at the hip joint work in synchrony with the acetabulum and femoral head for articular stability. There is a lack of understanding about ischiofemoral ligament (ISFL) anatomy and function.

Purpose: To assess the insertion of the ISFL in non-arthritic adult hips.

Material and methods: A retrospective analysis was performed in 72 patients who underwent magnetic resonance arthrogram (MRA) for the assessment of hip pain. The distribution of the ISFL components, the thickness, and the insertion site were assessed by concomitantly using the axial oblique, coronal, and sagittal MRA images.

Results: Two insertions of the ISFL anterior to the center of the femoral head were identified in 71 (99%) hips: (i) predominant anterior merging with the iliofemoral ligament as continuation of zona orbicularis, observed in all hips; and (ii) anterolateral junction of femoral neck and greater trochanter. Two ISFL parts (proximal and distal) were identified in 70 (97%) of the 72 studied hips. The proximal part was always thinner (mean 2.6 ± 0.7 mm) and originated from the ischium at the acetabular rim. The distal part was a continuation of the zona orbicularis, and the mean thickness was 6.7 ± 1.6 mm. Both parts merged as they coursed over the superior portion of the femoral head.

Conclusion: The predominant insertion of the ischiofemoral ligament is a merging to the iliofemoral ligament anteriorly. Surgical procedures such as hip arthroscopy involving the ISFL will affect the function of the iliofemoral ligament, and vice versa.
