BACKGROUND
sports hernia is a well-recognized cause of groin pain in athletes involved in sports, especially football and rugby. Loss of range of motion of the hip joint is a possible contributory factor to stress across the symphysis pubis leading to the instability.
METHODS
twenty-five athletes presenting with sports hernia were matched to age, sex, physical/sports activity and co-morbidities with twenty-five athletes without sports hernia. The range of movement of both the hips was compared in athletes of both the groups.
RESULTS
there was marked restriction of internal rotation with the hip flexed to 90 degrees (average 17 degrees) and external rotation (average 26 degrees) in sports hernia group compared to the control group. Other movements of the hip were comparable in both the groups.
CONCLUSION
the study highlights observation of limitation of hip rotation with the hip flexed to 90 degrees as a possible factor in the aetiology of sports hernia. There may be an association with other pathologies of the hip such as impingement that requires further investigation. Though this study has its limitation in being a small number and a case control study, it does helps in understanding the possible mechanism of development of this condition.
背景
运动性疝是参与体育运动（尤其是足球和橄榄球）的运动员腹股沟疼痛的一个公认原因。髋关节活动范围的丧失是导致耻骨联合处应力增加进而引起不稳定的一个可能因素。
方法
25名患有运动性疝的运动员与25名无运动性疝的运动员在年龄、性别、身体/体育活动及合并症方面进行匹配。比较两组运动员双侧髋关节的活动范围。
结果
与对照组相比，运动性疝组在髋关节屈曲90度时内旋（平均17度）和外旋（平均26度）有明显受限。两组髋关节的其他活动相当。
结论
该研究强调，观察到髋关节屈曲90度时旋转受限可能是运动性疝病因中的一个因素。可能与髋关节的其他病变如撞击有关，这需要进一步研究。尽管本研究存在样本量小及为病例对照研究的局限性，但它有助于理解这种疾病可能的发病机制。
