Results With the Cementless Spotorno Stem in Total Hip ArthroplastyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Increasingly young and active patients are undergoing total hip arthroplasty, making hip prosthesis survival rates an important issue. Cementless total hip arthroplasty provides better prosthesis longevity than does cemented hip arthroplasty, especially in younger patients. Because there is growing support in the literature for tapered geometry in cementless femoral components, we evaluated short-term results for total hip arthroplasty using Cementless Spotorno (CLS) titanium stems. We performed 100 consecutive primary cementless total hip arthroplasties in 87 patients during a 9-year period using CLS stems. Outc...

Hip Resurfacing Arthroplasty for Ankylosing SpondylitisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: We compared the results of the metal-on-metal hip resurfacing with the ceramic-on-ceramic total hip arthroplasty (THA) in 2 groups. The preoperative and postoperative ranges of motion (ROMs) were recorded. At the latest follow-up, both of the groups make satisfactory clinical and radiographic results. There was no significant difference in Harris hip score of the 2 groups, but the ROM of the hips in hip resurfacing group was significantly wider than THA group (P < .01). Hip resurfacing has better ROM improvement than THA, with the same pain relief. Its high stability and low dislocation rate allow patients to do ...

Abstract: Yttria-stabilized zirconia femoral heads from 3 different manufacturers were tested in vitro with respect to their phase stability and compared with retrieved zirconia heads. The monoclinic content on the surface of unused heads was analyzed by confocal Raman spectroscopy after exposure for increasing times to moist atmosphere. The increase in monoclinic content was then plotted as a function of geometric location on the head surface of the head and compared with that measured at similar locations after in vivo exposure. Profiles of residual stress associated to polymorphic transformation were also measured from ...
