Evaluation
acetabular abduction, femoral neck fracture
MINOR
An experienced surgeon who did not attend the treatments assessed the outcomes. Perioperatively, all patients underwent preoperative and postoperative radiological evaluations, including a standardized anteroposterior view of the pelvis as well as a lateral view of the affected hip and femur. The anteversion angle is the sine of the minor and long axes in the area of the elliptical projection of the cup. The acetabular abduction angle was defined as the angle between the acetabular long axis and the interteardrop line. The femoral offset is the sum of the distance from the rotation centre to the pelvis midline and the femur. The leg length discrepancy was measured as the difference in the perpendicular vertical displacement from the teardrop line to the lesser trochanter. Detailed measurements are shown in Fig. Female, 70 years old, femoral neck fracture (
