The authors present the case of a severe unstable slip of the proximal femoral epiphysis in a 14-year-old boy. A serious metabolic disorder diagnosed in the boy led to postponement of necessary surgical intervention.
The primary development of necrosis of the proximal femoral epiphysis during the 6 months following the slip is reported here. A good outcome was eventually achieved by three-plane vaigus, flexion and derotational osteotomy of the femur at second-stage surgery.
The authors emphasize the prognostic importance of stability assessment in the displaced epiphysis.
