N2 - Study design: Controlled laboratory cross-sectional. Objectives: 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. Background: 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. Methods: 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. Results: 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°. Conclusion: 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.
