Abstract:

BACKGROUND: Femoral neck anteversion is an angle between the posterior edge connection of the femoral condyle and the femur neck axis, involving the two ends of the femur. The measurement is more difficult, and many measurement methods lead to different results.
OBJECTIVE: To provide the anteversion of the femoral neck criterion for imaging diagnosis of hip joint through CT measurement research.
METHODS: Eighty adults who had performed CT scan were selected. The hip joints had no structural disease. In conventional position, the same side hip joint and knee joint were scanned and the anteversion of the femoral neck was calculated, called as definition value. In neutral position, the hip joint was scanned, and the anteversion of the femoral neck was measured, called as experiment value.
RESULTS AND CONCLUSION: The mean and standard deviation of the definition value of anteversion of the femoral neck was (10.48±2.40)°. The mean and standard deviation of the experiment value of anteversion of the femoral neck was (10.29±2.10)°. There were no significant differences between definition value and experiment value (P > 0.05). The method to measure experiment value was simple that was just to scan hip joint. Experiment value showed anteversion of the femoral neck exactly. It provided quantificat index for the diagnosis and treatment of hip disease.
