Delayed surgical drainage of a septic hip can lead to joint damage and avascular necrosis. • Slipped capital femoral epiphysis (SCFE) is a condition that occurs around puberty. • Look for it in adolescents and young teens, particularly those with a high BMI. Onset may be more chronic and achy or acute and intensely painful. • On physical exam look for a Trendelenburg gait, external rotation of the affected foot and a lack of active and passive hip internal rotation. • Slipped capital femoral epiphysis is treated with surgical stabilization of the affected hip, preventing progressive deformity that can lead to arthritis. • If you suspect bone or joint infection or SCFE, seek specialist consultation emergently. Do not administer antibiotics or allow the patient to weight bear until you have discussed the patient with an orthopaedic surgeon.
