Obligatory external rotation on flexion is a diagnostic clue for SCFE. Upto 46% of patients have thigh pain or hip pain-----------so for our exam point---------it's pain and obligation to externally rotate the thigh on flexion------------is SCFE

LCPDisease is clasically described as a child with--------LIMP +/- pain.

SCFE is a Salter-Harris type 1 fracture through the proximal femoral physis. The almost exclusive incidence of SCFE during the adolescent growth spurt indicates a hormonal role. Obesity is another key predisposing factor in the development of SCFE.

Legg-Calvé-Perthes disease (LCPD) is the name given to idiopathic osteonecrosis of the capital femoral epiphysis of the femoral head. LCPD most commonly is seen in persons aged 3-12 years, with a median age of 7 years.

Xray, CT or MRI can clearly show the difference.
