Objective

To determine the prevalence of athletic pubalgia imaging findings on MRI in patients with femoroacetabular impingement and assess for correlative risk factors.

Materials and methods

A retrospective search identified 156 hips with femoroacetabular impingement and a control group of 113 without femoroacetabular impingement that had an MRI performed between January 1, 2015, and January 1, 2018. Two fellowship-trained musculoskeletal radiologists reviewed studies for the presence of acute osteitis pubis, chronic osteitis pubis, adductor tendinosis, and tendon tear; rectus abdominis tendinosis and tendon tear; and aponeurotic plate tear. Findings were correlated with various clinical and imaging risk factors. Univariate and multivariate statistical analyses were performed.

Results

Imaging findings of adductor tendinosis (p = 0.02) and chronic osteitis pubis (p = 0.01) were more prevalent in FAI patients than controls. Univariate analyses in FAI patients showed that an alpha angle ≥ 60° had a higher prevalence of aponeurotic plate tears (p = 0.02) and adductor tendinosis (p = 0.049). Multivariate analyses showed that an alpha angle ≥ 60° had a higher prevalence of chronic osteitis pubis (OR = 2.27, p = 0.031), sports participation had a higher prevalence of adductor tendon tears (OR = 4.69, p = 0.013) and chronic osteitis pubis (OR = 2.61, p = 0.0058), and males had a higher prevalence of acute osteitis pubis (OR = 5.17, p = 0.032).

Conclusion

Sports participation, alpha angle ≥ 60°, and male sex predict a higher prevalence of athletic pubalgia imaging findings in patients with femoroacetabular impingement.

股骨髋臼撞击患者运动性耻骨影像学检查在MRI中的普遍性。

目的

为了确定股骨髋臼撞击患者运动性耻骨影像学检查在MRI中的患病率，并评估相关的危险因素。

材料和方法

一项回顾性研究确定了156例髋臼髋关节受累的髋关节和113例无股髋臼肌受累的对照组，他们在2015年1月1日至2018年1月1日期间进行了MRI检查。 ，慢性耻骨炎，内收肌腱病和肌腱撕裂；腹直肌肌腱病和肌腱撕裂; 和腱膜板撕裂。研究结果与各种临床和影像学危险因素相关。进行了单变量和多变量统计分析。

结果

 在FAI患者中，内收肌腱病（p  = 0.02）和慢性耻骨炎（p = 0.01）的影像学发现比对照组更普遍。FAI患者的单因素分析表明，α角≥60°时，腱膜板撕裂（p  = 0.02）和内收肌腱病（p  = 0.049）的患病率较高。多因素分析显示，α角≥60°的慢性耻骨炎患病率较高（OR = 2.27，p  = 0.031），体育参与的内收肌腱撕裂患病率较高（OR = 4.69，p  = 0.013）和慢性骨炎耻骨（OR = 2.61，p  = 0.0058），男性急性耻骨炎的患病率较高（OR = 5.17，p  = 0.032）。

结论

运动参与，α角≥60°以及男性预示股骨髋臼撞击患者运动性耻骨影像学检查的发生率较高。
