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 ...

PURPOSE To retrospectively evaluate factors leading to total hip arthroplasty (THA) in patients with subchondral insufficiency fractures (SIF) of the femoral head. METHODS. 5 men and 22 women aged 51 to 85 (mean, 72) years with SIF of the femoral head initially underwent conservative treatment. THA was later performed for 13 patients, as the hip pain became worse secondary to joint space narrow...

Intensive cultivation of vegetables and imbalanced fertilization depleted the soil nutrients caused low yield with poor quality crops. A novel microbial enriched biochar fertilizer combination could alleviate nutrient stress. Therefore, a field experiment was conducted 14 treatments [4 levels (5, 7.5,10, 15 t ha-1), 3 doses fertilizers (50, 75,100% recommended) along without absolute control] i...

The aqua adducts of the anticancer complexes [(eta(6)-X)Ru(en)Cl][PF(6)] (X=biphenyl (Bip) 1, X=5,8,9,10-tetrahydroanthracene (THA) 2, X=9,10-dihydroanthracene (DHA) 3; en=ethylenediamime) were separated by HPLC and characterised by mass spectrometry as the products of hydrolysis in water. The X-ray structures of the aqua complexes [(eta(6)-X)Ru(en)Y][PF(6)](n), X=Bip, Y=0.5 H(2)O/0.5 OH, n=1.5...

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...

BACKGROUND CONTEXT It is well accepted that total hip and knee arthroplasty (THA/TKA) for osteoarthritis (OA) is associated with reliable and sustained improvements in postoperative health-related quality of life (HRQoL). Although several studies have demonstrated comparable outcomes with THA/TKA after surgical intervention for lumbar spinal stenosis (LSS), the sustainability of the outcome aft...

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...
