[Slipped capital femoral epiphysis and overweight].

The slipped capital femoral epiphysis (SCFE) is defined as a nontraumatic epiphyseal separation and slipping of the proximal femoral epiphysis, which usually occurs during the adolescent growth spurt. Slipping of the upper femoral epiphysis may be classified as acute, chronic, and acute on chronic. The etiology of the disease is still not fully understood but seems to be multifactorial. The typical SCFE during puberty has to be differentiated from the atypical form, which may be associated with an endocrinological disorder or with its therapy. The typical SCFE may be found in male patients, with increased height and weight. It is likely that the growth rate is slightly accelerated before slippage. Obesity is often associated with a decreased femoral anteversion accounting for abnormal mechanical shear forces at the growth plate. SCFE is treated surgically. Surgical methods are administered according to the degree of disease. Because of possible alterations of blood supply to the femoral head, acute SCFE is an emergency. Following SCFE, complications such as chondrolysis and avascular necrosis are feared.
