The authors report the data obtained in a bone scan study conducted in 15 patients with cementless total hip arthroplasty. The study was conducted a minimum of 6 months and a maximum of 46 months postsurgery. Contrary to what occurs for cemented prostheses, we used bone scan not as a diagnostic aid for complications, but in order to evaluate the osteogenetic response of the bone to a cementless prosthetic implant. Zonal bone scan high uptake revealed specific areas of overloading, or, when localized in the para-articular region, they anticipated the presence of ossifications before they became visible radiographically. Bone scan was also useful in monitoring the incorporation and remodelling phases of the auto and/or homoplastic bone grafts used.
作者报告了对15例非骨水泥型全髋关节置换术患者进行骨扫描研究获得的数据。该研究在术后至少6个月、最多46个月进行。与骨水泥型假体的情况相反，我们使用骨扫描并非用于辅助诊断并发症，而是为了评估骨对非骨水泥型假体植入物的成骨反应。区域骨扫描高摄取显示了特定的过载区域，或者当位于关节旁区域时，它们在影像学上可见骨化之前就预示了骨化的存在。骨扫描在监测所使用的自体和/或同种异体骨移植的融合和重塑阶段也很有用。
