Abstract In the present work, Zn-HA composites were developed by powder metallurgy route targeted for bone implant applicaitons. powders with varying HA content (1, 2, and 4 wt.%) ball milled 1 hr sintered to produce composite compacts. X-ray diffraction (XRD) studies done all No impurities observed in powders. Microstructural observations revealed formation of lamellar structure due plastic de...

Infection is a major complication of implantable medical devices, which provide a scaffold for biofilm formation, thereby reducing susceptibility to antibiotics and complicating treatment. Hematogenous implant-related infections following bacteremia are particularly problematic because they can occur at any time in a previously stable implant. Herein, we developed a model of hematogenous infect...

This article investigates mechanics issues related to potential use of a recently developed porous titanium (Ti) material for load-bearing implants. This material may have advantages over solid Ti of enhancing the bone-implant interface strength by promoting bone and soft tissue ingrowth and of reducing the bone-implant modulus mismatch, which can lead to stress shielding. Experimental data fro...

BACKGROUND Infection in orthopedic surgery is a disaster both for the patient and surgeon. Although its incidence has been reduced due to modern theatre facilities and aseptic measures but in developing countries its prevalence is still high. It is better to prevent infection rather than to treat it. The objective of this study is to know the frequency of infection in orthopedic implant surgery...

BACKGROUND C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) have been shown to be useful for diagnosis of prosthetic hip and knee infection. Little information is available on CRP and ESR in patients undergoing revision or resection of shoulder arthroplasties or spine implants. METHODS/RESULTS We analyzed preoperative CRP and ESR in 636 subjects who underwent knee (n=297), hi...
