Slipped Capital Epiphysis (Adolescent Coxa Vara)
Slipped capital femoral epiphysis is the name given to the disorder when the head (“ball”) of the femur separates from the rest of the femur (thigh bone) along the growth plate, causing the femur to slip in a backwards direction. This slippage may be acute or chronic.
Acute slippage typically presents in overweight children or young, rapidly growing adolescents with a history of trauma. Chronic slippage typically presents as a gradually increasing hip or knee pain and an antalgic (altered walking to avoid pain) gait.
