Bateman universal proximal femoral arthroplasty combined with acetabular reaming was performed in 35 cases of osteoarthritis of the hip joint. The patients were from 21 to 59 years of age (average, 41 years of age) at the time of operation. The postoperative outcome for a middle term ranging from two to eight years, with an average of five years and nine months, was studied along with postoperative migration of the outer head. The clinical outcome, assessed by the evaluation criteria for hip function proposed by the Japanese Orthopaedic Association, was favorable. A stable average score of greater than 80 occurred for eight years postoperatively; the average preoperative score was 45. Of the 35 cases, seven cases (20%) had an upward migration of the outer head, and one case (2.9%) had an inward migration of 5 mm or more, but the migration did not affect the clinical outcome in any case. There was no certain relationship between the degree of rotation of the outer head and the extent of its migration. Migration of the outer head was prevented by postoperative exercise, in which total loading was initiated after the completion of the radiolucent zone around the outer head and its circumferential zone of osteosclerosis.
对35例髋关节骨关节炎患者实施了Bateman通用型股骨近端置换术联合髋臼扩孔术。手术时患者年龄为21至59岁（平均41岁）。研究了术后两至八年（平均五年零九个月）的中期结果以及术后股骨头外移情况。根据日本矫形外科学会提出的髋关节功能评估标准进行评估，临床结果良好。术后八年平均评分稳定在80分以上；术前平均评分为45分。35例患者中，7例（20%）股骨头外移向上，1例（2.9%）向内移位5毫米或更多，但移位在任何情况下均未影响临床结果。股骨头旋转程度与其移位程度之间无明确关系。通过术后锻炼防止了股骨头移位，即在股骨头周围的射线可透区及其骨硬化圆周区完成后开始完全负重。
