Traditionally arthrography performed under general anesthesia with conventional fluoroscopy is performed to assess congruency between the femoral head and the acetabulum in a variety of positions 3.

Eventually, the femoral head begins to fragment stage 2with subchondral lucency crescent sign and redistribution of weight-bearing stresses leading to thickening of some trabeculae which become more prominent. This may precipitate the presentation or the realisation of symptoms that in fact had been long standing. Slipped upper femoral epiphysis Slipped upper femoral epiphysis. Case 9 Case 9.
