Abstract

Slipped capital femoral epiphysis (SCFE) is a common adolescent hip disorder. The etiology of SCFE includes biomechanical and biochemical factors. SCFEs are classified as stable and unstable and are more common in boys than girls and in certain racial groups; most children with SCFEs are obese. Bilateral SCFEs may have a simultaneous or sequential presentation. Imaging studies show a posterior slip of the epiphysis relative to the metaphysis, seen early on lateral radiographs. The most common and effective initial treatment for stable SCFEs is in situ central single-screw fixation; other options include epiphysiodesis, and osteotomy with or without surgical dislocation of the hip. Later reconstruction options, typically reserved for the child with functional abnormalities, include proximal femoral osteotomy, or surgical dislocation of the hip with removal of metaphyseal prominent bone to remove the source of femoroacetabular impingement. Unstable SCFEs have an increased risk of osteonecrosis; the role of reduction, methods of fixation, and decompression are controversial. The natural history of untreated SCFEs is associated with the risk of progression and later degenerative joint disease. Based on treatment methods of 30 to 40 years ago, in situ fixation provided the best long-term function with the lowest risk of complications and the most effective delay of degenerative arthritis regardless of the severity of the SCFE. Newer technologies and techniques are allowing the reevaluation of the role of either acute or later reconstructive osteotomy. It has not yet been determined if these improved techniques will result in better outcomes than in the past. Surgical dislocation of the hip with epiphyseal orientation is a considered treatment option for those technically adept at the procedure; however, the long-term outcome compared with in situ fixation is still unknown.
