<prompt> Radiological sign in case of Pehes disease -Epiphyseal calcificationOrganized calcificationLateral subluxation femur headRestriction of abduction  <response>: Pehes disease is divided into 5 distinct radiographic stages : cessation of growth of capital femoral epiphysis - occurs after initial ischaemic episode last for 6-12 months . subchondral fracture - causes collapse of head ischemia ,visible on radiograph for an average of three months resorption - necrotic epiphyseal bone beneath the subchondral fracture is gradually irregularly resorbed takes 6-12 months re- ossification- ossification of vascular fibrous tissue takes place .the capital femoral epiphysis regains its normal strength ,takes 6-24 months healing or residual stage - femoral head is healed with or without residual deformity.
