Innovations and advances in material engineering surface play a key role developing modern, safe, durable, biocompatible implants. The bibliometric analysis had been conducted to understand the active authors, organizations, journals, countries involved research domain of “hip-implants”. All published articles related “hip- implants” from “Scopus”, were Journal Bone Joint Surgery Arthroplasty. ...

BACKGROUND The degenerative changes in hip joints observed in patients RA are associated with acetabular bone deficiencies. Therefore total hip arthroplasty performed in such patients requires bone grafting to restore the deficiencies. The aim of the study was to assess the long term-term results of primary total hip arthroplasty in patients with RA including an assessment of the usefulness of ...

case presentation we report the case of a 4.5-year-old boy with acute onset bilateral hip and low back pain and inability to walk. examination of passive movements showed that both hips were painful and restricted. conclusions bone pain presenting as localized bilateral irritable hip could be considered as a diagnostic clue related to malignancies. introduction bone pain is common in children. ...

The fatigue failure of bone cement, leading to loosening of the stem, is likely to be one mode of failure of cemented total hip replacements. There is strong evidence that cracks in the cement are initiated at voids which act as stress risers, particularly at the cement-stem interface. The preferential formation of voids at this site results from shrinkage during polymerisation and the initiati...

The objective of this study was to analyse retrieved human femoral bone samples using three different test methods, to elucidate the relationship between bone mineral density and mechanical properties. Human femoral heads were retrieved from 22 donors undergoing primary total hip replacement due to hip osteoarthritis and stored for a maximum of 24 hours postoperatively at + 6 °C to 8 °C.Analysi...

osteoporosis as a skeletal disorder characterize by compromised bone strength predisposing a person to an increased risk of fracture. all people should be encouraged to take efforts to prevent bone loss and fractures. nutrition is one of several factors that can be modified to reduce osteoporosis risk. the purpose of this review article is assessment the role of the other nutrients the exceptio...

The implanting of a hip endoprosthesis changes the mechanical loading in a hip. The changing in loading causes bone remodeling. The loss of loading leads to bone atrophy, whereas an increase in loading leads to hypertrophy of the bones. We investigated the relationship between the clinical result and change in periprosthetic bone mineral density. The Harris hip score was used to measure the cli...

aim :  the goal of the present study was to assess the effect of omeprazole on bone mineral density and frequency of osteopenia and osteoporosis. background : the effect of omeprazole on bone turnover and the role of stomach ph alteration in calcium absorption have not been completely understood. patients and methods : in a case-control study, 58 patients who were referred to loghman hospital, ...

BACKGROUND AND PURPOSE One of the greatest problems of revision hip arthroplasty is dealing with lost bone stock. Good results have been obtained with impaction grafting of allograft bone. However, there have been problems of infection, reproducibility, antigenicity, stability, availability of bone, and cost. Thus, alternatives to allograft have been sought. BoneSave is a biphasic porous cerami...

The increasing need for total hip replacement (THR) in an ageing population will inevitably generate a larger number of revision procedures. The difficulties encountered in dealing with the bone deficient acetabulum are amongst the greatest challenges in hip surgery. The failed acetabular component requires reconstruction to restore the hip centre and improve joint biomechanics. Impaction bone ...
