Flattening of acetabular roof in skeletally immature patients has been demonstrated in chronic acetabular rim overload but even short-term triggers may transform healthy hip in a dysplastic one around triradiate cartilage closure time frame. We collected three possible causes of acetabular flattening after a short-term overload in patients at the end of their potential growth of the acetabulum: congenital femoral deficiency treated with surgical lengthening, slipped capital femoral epiphysis treated with anatomical reorientations and intra-articular disease. Excessive pressure on the acetabulum for timeframe shorter than one year may lead to acetabular roof flattening in patients between 12 and 14 years old.
