Abstract

We studied 2 types of a cementless total hip prosthesis in dogs. Both were coated with titanium plasma-spray. In both components, the pores in the deep layer of 1 group were further coated with apatite and wollastonite containing glass-ceramic (AW glass-ceramic). 50 dogs underwent unilateral total hip replacements, and were killed at 1, 3, or 6 months postoperatively. We evaluated the femoral and the acetabular components mechanically and histologically. At 1 month, the detaching load and bone ingrowth of the AW glass-ceramic-coated femoral and acetabular components were higher than those of the control implants. At 3 and 6 months there were no differences between the 2 types of components. Thus, AW glass-ceramic enhanced the early phase of cementless implant fixation.

摘要

我们在犬类中研究了两种非骨水泥型全髋关节假体。两者均采用钛等离子喷涂涂层。在两组部件中，一组深层的孔隙进一步涂覆了含磷灰石和硅灰石的微晶玻璃（AW微晶玻璃）。50只犬接受了单侧全髋关节置换，并在术后1个月、3个月或6个月处死。我们对股骨和髋臼部件进行了力学和组织学评估。在1个月时，AW微晶玻璃涂层的股骨和髋臼部件的拔出负荷和骨长入高于对照植入物。在3个月和6个月时，两种类型的部件之间没有差异。因此，AW微晶玻璃增强了非骨水泥植入物固定的早期阶段。
