Pseudarthrosis is a rare complication of slipped capital femoral epiphysis. Traumatic pseudarthrosis of the femoral neck is treated with bone-grafting, osteotomy, and open reduction with internal fixation or with osteotomy alone. Severe slips are treated with closed pinning, epiphyseodesis with bone-grafting, open reduction, or osteotomy. Open reduction is associated with a high risk of avascular necrosis. We are not aware of any guidelines for the treatment of pseudarthrosis following slipped capital femoral epiphysis. The purposes of this report are to present the case of a patient who had this rare condition and to discuss alternative methods of treatment.
