Transtrochanteric rotational osteotomy for severe slipped capital femoral epiphysis

We performed transtrochanteric rotational osteotomy to treat severe slipped capital femoral epiphysis in four young patients. All four male patients, with an age range of 12-22 years, were followed for an average of 2 years and 10 months. The JOA score of 37 points preoperatively improved to an average of 90 points postoperatively. The posterior tilt angle (PTA) of 82 degrees preoperatively improved to an average of 24 degrees postoperatively. The flexion angle of the affected hip joint in neutral improved from 10 degrees-25 degrees to 70 degrees-90 degrees. Although one patient with acute on chronic type of SCFE developed osteonecrosis of the femoral head after the operation, the function of the hip joint was restored. Our results suggest that transtrochanteric rotational osteotomy is a valuable option for the treatment of severe slipped capital femoral epiphysis in young patients.
