Unconstrained tripolar implants for primary total hip arthroplasty in patients at risk for dislocation.
We performed a retrospective study on 167 primary total hip arthroplasty (THA) procedures in 163 patients at high risk for instability to assess the reliability of unconstrained tripolar implants (press-fit outer metal shell articulating a bipolar polyethylene component) in preventing dislocations. Eighty-four percent of the patients had at least 2 risk factors for dislocation. The mean follow-...
متن کاملContemporary Ceramic Total Hip Arthroplasty in Patients with Cerebral Palsy: Does It Work?
BACKGROUND Adult patients with cerebral palsy (CP), who have advanced degenerative arthritis of the hip, have been treated with resection arthroplasty and arthrodesis. Although total hip arthroplasty (THA) has also been used as one of the alternative options, there are few studies on contemporary bearings used in THA. Therefore, we evaluated the results of the contemporary ceramic-on-ceramic TH...
متن کاملLower Dislocation Rate Following Total Hip Arthroplasty via Direct Anterior Approach than via Posterior Approach: Five-Year-Average Follow-Up Results
OBJECTIVE The aim of the study was to compare the dislocation rate between total hip arthroplasty (THA) via direct anterior approach (DAA) and via posterior approach (PA). METHODS We compared a consecutive series of 139 THAs via DAA with 177 THAs via PA. All study patients received ceramic-on-ceramic bearing surfaces and similar uncemented prostheses. Dislocation-free survival after THA was e...
متن کاملWhat every surgeon should know about Ceramic-on-Ceramic bearings in young patients
Based on the exceptional tribological behaviour and on the relatively low biological activity of ceramic particles, Ceramic-on-Ceramic (CoC) total hip arthroplasty (THA) presents significant advantagesCoC bearings decrease wear and osteolysis, the cumulative long-term risk of dislocation, muscle atrophy, and head-neck taper corrosion.However, there are still concerns regarding the best techniqu...
متن کاملCementless Revision Total Hip Arthroplasty with Ceramic Articulation
PURPOSE The results of ceramic-on-ceramic (CoC) bearing surfaces in primary total hip arthroplasty (THA) were well known. However, it was not known in revision THA. The purpose of this study is to report the results of revision THA with ceramic articulation. MATERIALS AND METHODS A total of 112 revision THAs were evaluated. The mean age at the time of surgery was 51.6 years (27.7 to 84.2 year...
