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.
在9名儿童中发现11个髋关节存在髋臼发育不良，表现为髋关节发育性脱位。该组患儿中未出现脱位的临床体征——内收肌紧张及跛行，同时X线平片显示股骨头从骨盆中突出的情况也不明显。关节造影显示髋臼发育不良但无脱位。对髋关节发育不良进行准确分级有助于避免此类误诊，而误诊在该病症的治疗中一直是个反复出现的问题。
