Acetabular revisions using porous tantalum components: A retrospective study with 5-10 years follow-up
AIM To evaluate the clinical and X-ray results of acetabular components and tantalum augments in prosthetic hip revisions. METHODS Fifty-eight hip prostheses with primary failure of the acetabular component were reviewed with tantalum implants. The clinical records and X-rays of these cases were retrospectively reviewed. Bone defect evaluations were based on preoperative CT scans and classifi...
متن کاملFinite Element Analysis Stress Distribution Acetabular Cup Biomaterial FINITE ELEMENT ANALYSIS OF PERI-ACETABULAR STRESS OF CEMENTED, METAL-BACKED, AND POROUS TANTALUM BACKED ACETABULAR COMPONENTS
Introduction: In contemporary THA there are two broad approaches to acetabular cup design and materials. One is an all-polyethylene design with polymethylmethacrylate (PMMA) cement. PMMA possesses a modulus of elasticity of about 2 GPa, which is between that of trabecular and subchondral bone. The second more popular approach, especially for active, younger patients, is the porous metal-backed ...
متن کاملMinimum 5-year follow-up for primary THA using a tapered, proximally coated cementless stem.
The purpose of this study was to assess the survivorship of a proximally coated, cementless femoral stem used for total hip arthroplasty at a minimum 5-year follow-up by assessing clinical outcomes and implant survival. A total of 936 primary total hip arthroplasties were performed in 854 patients by 3 high-volume surgeons between 2001 and 2007. Patients included 385 men and 469 women with a me...
متن کاملAcetabular reconstruction using a Kerboull cross-plate, structural allograft and cemented dual-mobility cup in revision THA at a minimum 5-year follow-up.
The current study aimed to evaluate the outcome of a continuous and prospective series of 61 revision THAs with AAOS grade III and IV acetabular bone defect reconstruction using a Kerboull cross-plate, structural allograft and cemented dual mobility cup (Saturne, Amplitude, Valence, France). At a 7.5-year mean follow-up, no instability was reported after revision. In addition, no failure of the...
متن کاملCementless uncoated polyethylene acetabular components in total hip replacement. Review of five- to 10-year results.
We reviewed the results of 545 consecutive total hip replacements using a cementless non-coated high-density polyethylene acetabular component combined with a cemented Müller stem at five to 10 years. In all, 421 patients (445 hips) were available for review, 118 by questionnaire and 303 by examination and radiography. Of these, 86% had a good or excellent result. We found a high rate of radiol...
