背景:髋关节囊是髋关节功能和稳定性的重要组成部分,它的厚度与某些医疗条件密切相关,手术结果,和康复治疗。目前,在临床实践中,髋关节囊厚度主要使用磁共振成像(MRI)测量,有限的超声检查用于此目的。
方法:我们回顾性评估了在2017年2月至2023年3月期间访问我们运动医学部并在同一侧进行了髋关节MRI和超声成像的患者。所有患者术前均行髋关节MRI及超声检查,两次考试的时间间隔不超过三个月。对同一患者的MRI和超声图像进行髋关节囊厚度测量,以分析其一致性。此外,我们测量了α角,横向中心边缘角,髋臼前倾角,并分析其与超声测量髋关节囊厚度的相关性。
结果:本研究共纳入307例患者,MRI和超声测量髋关节囊厚度为5.0±1.2mm和5.0±1.5mm,分别。Bland-Altman分析显示出良好的一致性或一致性。配对t检验得到的p值为0.708,表明两种方法之间没有显著的统计学差异。髋臼前倾角与超声测量的囊厚度之间的相关性分析得出的p值为0.043,表明髋臼前倾角与囊厚度可能呈负相关。
结论:通过超声和MRI获得的关节囊厚度测量结果具有良好的一致性,提示超声可在临床实践中作为MRI测量髋关节囊厚度的替代方法。髋臼前倾角与髋关节囊厚度有显著相关性,表明在这一领域进一步研究的潜力。
BACKGROUND: The hip joint
capsule is an essential component of hip joint function and stability, and its thickness is closely associated with certain medical conditions, surgical outcomes, and rehabilitation treatments. Currently, in clinical practice, hip joint
capsule thickness is predominantly measured using magnetic resonance imaging (MRI), with limited utilization of ultrasound examinations for this purpose.
METHODS: We retrospectively evaluated patients who visited our Sports Medicine Department between February 2017 and March 2023 and underwent both hip joint MRI and ultrasound imaging on the same side. All patients had undergone preoperative hip joint MRI and ultrasound examinations, with the time gap between the two examinations not exceeding three months. Measurements of hip joint
capsule thickness were taken on both MRI and ultrasound images for the same patients to analyze their consistency. Additionally, we measured the alpha angle, lateral center-edge angle, acetabular anteversion angle, and femoral anteversion angle of the patients\' hip joints and analyzed their correlation with hip joint capsule thickness measure by ultrasound.
RESULTS: A total of 307 patients were included in this study, with hip joint capsule thickness measured by MRI and ultrasound being 5.0 ± 1.2 mm and 5.0 ± 1.5 mm, respectively. The Bland-Altman analysis demonstrates good agreement or consistency. The paired t-test resulted in a p-value of 0.708, indicating no significant statistical difference between the two methods. The correlation analysis between acetabular anteversion angle and ultrasound-measured
capsule thickness yielded a p-value of 0.043, indicating acetabular anteversion angle and capsular thickness may have negative correlation.
CONCLUSIONS: The measurements of joint
capsule thickness obtained through ultrasound and MRI showed good consistency, suggesting that ultrasound can be used in clinical practice as a replacement for MRI in measuring hip joint capsule thickness. There was a significant correlation between acetabular anteversion angle and hip joint capsule thickness, indicating potential for further research in this area.
