Background This study investigated the radiological factors that correlated with progression
of collapse and joint space narrowing after transtrochanteric posterior rotational osteotomy
(PRO) for osteonecrosis of the femoral head. Methods This study reviewed 51 hips in 47
patients with a mean follow-up of 11 years (5–20). The subjects included 29 males and 18
females with a mean age of 34 years (12–54) at the time of surgery. The 51 hips were
divided into two groups based on the radiological outcome (group I: evidence of progression …
