Between 1976 and 1982, 126 low friction arthroplasties were implanted in primary arthrosis of the hip. The displacement rate or acetabular loosening related to the type osteoblastic response to the disease were studied. The hips were subdivided into three groups based on the radiographical aspect observed prior to implant. The atrophic type revealed a greater incidence for this type of complication (27.3%) whereas cases classified as normotrophic revealed a 5.6% incidence and hypertrophic a 6.1% incidence. The authors conclude that the type of bone response in primary arthrosis plays an important role in the occurrence of acetabular mobilization, and that osteoblastic response may be considered to be of prognostic value together with other well-known factors in the evolution of this type arthroplasty.
1976年至1982年间，126例低摩擦人工关节置换术被植入髋关节原发性骨关节炎患者体内。研究了与疾病的成骨细胞反应类型相关的移位率或髋臼松动情况。根据植入前观察到的影像学表现，将髋关节分为三组。萎缩型出现这种并发症的发生率更高（27.3%），而归类为营养正常型的病例发生率为5.6%，肥大性的发生率为6.1%。作者得出结论，原发性骨关节炎中的骨反应类型在髋臼松动的发生中起重要作用，并且成骨细胞反应与这种类型人工关节置换术发展过程中的其他已知因素一起，可能被认为具有预后价值。
