Controlled laboratory cross-sectional.
To investigate the relationship between femoral version (FV), measured by MRI (FVMRI), Craig's test and hip rotation range of motion (ROM). To determine rotation ROM values associated with FVMRI categories: excessive anteversion, normal version and retroversion.
Abnormal FV values are associated with hip disorders, such as osteoarthritis, structural instability, acetabular labral tears and femoroacetabular impingement. Clinical assessment of FV may allow clinician to identify the effect of bony abnormalities on hip rotation ROM to guide clinical decisions.
Thirty-eight participants with chronic hip joint pain (CHJP) and 38 matched controls participated. MRI was used to determine FVMRI. A digital inclinometer was used to assess Craig's test, hip internal rotation (IR) and external rotation (ER) with hip flexed to 90° (90°), and hip IR/ER with hip in neutral flexion/extension (0°). ROM differences (ROMdif) were determined by subtracting ER from IR. Pearson correlation coefficients were used to assess the relationship between FVMRI and clinical variables. One-way analysis of variance (ANOVA) was used to compare rotation ROM among FVMRI categories.
There were no differences between CHJP and control groups in demographics, FVMRI, Craig's test or ROM. ROMdif0° showed the highest correlation (r = 0.63) with FVMRI, then IR90° (r = 0.61) and Craig's test (r = 0.61). Differences were noted among FVMRI categories for rotation ROM except hip ER90°.
Hip rotation ROM and Craig's test may be used for screening when imaging is not indicated. A 20° difference between hip IR and ER ROM would be suggestive of abnormal FV.
对照实验室的横断面研究。
研究通过 MRI（FVMRI）测量的股骨前倾角（FV）与 Craig 试验和髋关节旋转活动范围（ROM）之间的关系。确定与 FVMRI 分类相关的旋转 ROM 值：过度前倾角、正常前倾角和后倾角。
异常的 FV 值与髋关节疾病有关，如骨关节炎、结构不稳定、髋臼唇撕裂和股骨髋臼撞击。对 FV 的临床评估可以让临床医生识别骨骼异常对髋关节旋转 ROM 的影响，从而指导临床决策。
38 名慢性髋关节疼痛（CHJP）患者和 38 名匹配的对照组参与者参与了这项研究。使用 MRI 来确定 FVMRI。使用数字测斜仪评估 Craig 试验、髋关节内旋（IR）和外旋（ER），髋关节弯曲至 90°（90°），髋关节在中立位屈伸（0°）时测量髋关节内旋/外旋。ROM 差值（ROMdif）通过从 ER 中减去 IR 来确定。Pearson 相关系数用于评估 FVMRI 与临床变量之间的关系。单因素方差分析（ANOVA）用于比较 FVMRI 分类之间的旋转 ROM。
CHJP 组和对照组在人口统计学、FVMRI、Craig 试验或 ROM 方面没有差异。ROMdif0°与 FVMRI 的相关性最高（r=0.63），其次是 IR90°（r=0.61）和 Craig 试验（r=0.61）。除髋关节 ER90°外，FVMRI 分类之间在旋转 ROM 方面存在差异。
当不需要影像学检查时，可以使用髋关节旋转 ROM 和 Craig 试验进行筛查。髋关节内旋和外旋 ROM 之间相差 20°可能提示 FV 异常。
