The authors conducted a clinical and radiographic study on a group of 43 patients with hip arthroprostheses selected from the three-year period from 1984 to 1987, characterized by no immediate postoperative complications, no positional defects on X-ray examination, and with a Renther test greater than 1. Prostheses were cemented, cementless and combined. Scintigraphy was evaluated for areas of subdivision in the proximal end of the femur and acetabulum, making a semi-quantitative comparison of the intensity of captation of each area with that of the skull and sacroiliac synchondrosis. The authors emphasize that this procedure is both reliable and easy for the early determination (pre-clinical and pre-radiographic) of any complications. A scintigraphic examination of the single areas was also capable of revealing the site and entity of prosthetic bone-to-implant interactions. According to the results reported, PCA prostheses seem to be characterized by better biocompatibility.
作者对1984年至1987年这三年间选取的43例髋关节置换患者进行了临床和影像学研究，这些患者的特点是术后无即刻并发症，X线检查无位置缺陷，且Renther试验大于1。假体类型包括骨水泥型、非骨水泥型和混合型。对股骨近端和髋臼的细分区域进行了闪烁扫描评估，对每个区域的摄取强度与颅骨和骶髂关节软骨结合处的摄取强度进行了半定量比较。作者强调，该方法对于早期确定（临床前和影像学前）任何并发症既可靠又简便。对单个区域的闪烁扫描检查还能够揭示假体与植入物骨相互作用的部位和程度。根据报告结果，PCA假体似乎具有更好的生物相容性。
