摘　　要：目的通过CT测量股骨前倾角对髋关节撞击综合征(FAI)病例组和正常对照组进行对比分析,探讨股骨前倾角在FAI不同亚型患者中的临床意义。方法搜集经手术证实的58例髋关节撞击综合征患者,测量其股骨前倾角,并与正常成人对照组比较分析。结果无论是病例组还是对照组,股骨前倾角在性别上均具有统计学差异(P<0.02),而在左髋和右髋上无统计学意义。股骨前倾角在FAI不同亚型和正常对照组的平均值分别为(18.90±6.17)°、(28.60±6.28)°、(22.88±8.83)°、(21.81±5.50)°,除混合型FAI组与正常组的股骨前倾角无统计学差异,其余各两组间均具有统计学差异。结论CT扫描是FAI患者术前测量股骨前倾角的主要手段。FAI不同亚型的股骨前倾角之间存在一定的差异性,股骨前倾角过大或过小对FAI的发病机制及治疗起重要作用。Objective To investigate the clinical significance of femoral anteversion in patients with different subtypes of FAI by comparing the angle measured on CT with normal control group.Methods A total of 58 patients with surgically confirmed femoroacetabular impingement from May 2017 to September 2018 were enrolled.The femoral anteversion was measured and compared with the normal adult control group.Results In both the case group and the control group,women had a significantly larger anteversion than men(P<0.02),but there was no statistical difference in the left hip and right hip.The mean values of femoral anteversion in different subtypes of FAI and normal controls were(18.90±6.17)°,(28.60±6.28)°,(22.88±8.83)°and(21.81±5.50)°.There was no significant difference in femoral anteversion between the mixed-type FAI group and the normal group,but there was statistical difference between the other two groups.Conclusion CT scan is the main method for measuring femoral anteversion in patients with FAI before operation.There is a certain difference between the anteversion in different subtypes of FAI.Excessive or too small femoral anteversion plays an important role in the pathogenesis and treatment of FAI.
