Fig. 5. From: Osseous Remodeling After Femoral Head-neck Junction Osteochondroplasty.

There was a decrease of the alpha angle and increase of the head-neck offset (HNO) and head-neck offset ratio (HNO ratio).

We observed no correlation (p = 0.34) between the Harris hip score and degree of recorticalization.

The recorticalization of the femoral head-neck junction was assessed by comparing postoperative and followup films. They were labeled (A) “none” if no sclerotic margin was noted at the resection site and (B) “partial” if sclerosis was present but was incomplete. (C) If there was a continuous cortical line between the femoral head and the head-neck junction, the sample was graded as “complete.” The arrow indicates the location of bone resection.

(A) The alpha angle is measured by applying a circular template to match the diameter of the femur. A line is drawn along the longitudinal axis of the femoral neck. A second line is drawn from the center of the circular template to the point where the femoral head deviates from the circular template. The angle subtended by these lines forms the alpha angle. (B) Example of improved alpha angle after recontouring of the femoral head-neck junction is shown.

(A) The head-neck offset (HNO) was measured in a preoperative measurement on a frog leg lateral view. Line 1 is drawn to bisect the femoral neck. Parallel lines are draw tangential to the femoral neck (Line 2) and the femoral neck (Line 3). The HNO is the measurement of the distance between Lines 2 and 3. (B) An example demonstrates the measurement of the same patient after the osteochondroplasty. The circle template allows for consistent measurement across time points.
