Slipped capital femoral epiphysis (SCFE or skiffy, slipped upper femoral epiphysis, SUFE or souffy) is a medical term referring to a fracture through the growth plate (physis), which results in slippage of the overlying end of the femur (epiphysis). Normally, the head of the femur, called the capital, should sit squarely on the femoral neck. Abnormal movement along the growth plate results in the slip. The femoral epiphysis remains in the acetabulum (hip socket), while the metaphysis (end of the femur) move in an anterior direction with external rotation. SCFE is the most common hip disorder in adolescence. SCFEs usually cause groin pain on the affected side, but sometimes cause knee or thigh pain. One in five cases involve both hips, resulting in pain on both sides of the body. SCFEs often occur in obese adolescent males, especially young Black males, although it also affects females. Symptoms include the gradual, progressive onset of thigh or knee pain with a painful limp. Hip motion will be limited, particularly internal rotation.
