Regardless of the mechanism of proximal femoral epiphyseal separation, the prognosis is poor secondary to the development of osteonecrosis. Independent of the method or timing of treatment, the development of osteonecrosis has been reported to be 100%5. The long-term outcome for these patients is dismal, with most patients requiring hip salvage procedures and, ultimately, either arthrodesis or total hip arthroplasty5.
