title: Acetabular dysplasia presenting as developmental dislocation of the hip.
abstract: Eleven hips in nine children were identified with acetabular dysplasia, which presented as developmental dislocation of the hip. The clinical signs of dislocation--tight abductors and a limp, associated with a plain radiograph showing the femoral head protruding from the pelvis--were not evident among this group. Arthrography showed acetabular dysplasia but no dislocation. Accurate grading of hip dysplasia can help to avoid such misdiagnoses, which have presented a recurring problem in the management tof this condition.
