Total hip metal arthroplasty (THA) constitutes an important proportion of the standard clinical implant usage in Medical Physics and Biomedical Engineering. A computational nonlinear optimization is performed with two commonly materials Metal-on-Metal (MoM) THA. Namely, Cast Co-Cr Alloy Titanium. The principal result numerical determination K adimensional-constant parameter model. Results from ...

INTRODUCTION Rheumatoid arthritis (RA) is one of the major indications of total hip (THA) or knee (TKA) arthroplasty. International studies have suggested that RA is a risk factor for prosthesis infections. OBJECTIVES To compare patients with RA and patients with osteoarthritis (OA) of other etiologies with regard to the incidence of prosthesis, incisional, and other systemic postoperative in...

Quality of life index (Quality Of Well-Being [QWB]) was used to calculate the costs per quality of well year (QWY) in total hip arthroplasty (THA) and compare it to other interventions. Ninety-eight primary and/or revision THA were reviewed. Patients had minimum 1-year follow-up. Quality of life index was used to calculate the costs per QWY in primary and revision THA. Preoperative QWB for prim...

Abstract Background Stress shielding after total hip arthroplasty (THA) leads to loss of bone mineral density (BMD) around the femoral implants, particularly in proximal area. Loss BMD implant is likely occur within 1 year THA; however, its severity depends on patient characteristics. This study evaluated preoperative factors correlated with zone 7 THA. Methods retrospective cohort included 48 ...

Tacrine (THA) and physostigmine (PHS) have been used in Alzheimer's disease therapy for their anticholinesterasic activity. Here we show that THA is taken up in rat lysosomes in an energy-dependent manner, and that it is also accumulated in acidic compartments of rat thymocytes and neuroblastoma cells. A concentration of THA less than 1 mM dissipated the pH gradient (delta pH) in all the above ...

BACKGROUND This meta-analysis compared clinical outcomes of arthroplasty vs. osteosynthesis for displaced femoral neck fractures. METHODS Meta-analysis was performed on the difference in revision rate and overall mortality between participants undergoing osteosynthesis vs. total hip arthroplasty (THA), osteosynthesis vs. hemiarthroplasty (HA), or THA vs. HA. RESULTS Pooled direct and indire...
