Microstructure analysis and wear behavior of titanium cermet femoral head with hard TiC layer

Journal of Biomechanics — Mon, 19 Oct 2009 00:00:00 +0100

Abstract: Titanium cermet was successfully synthesized and formed a thin gradient titanium carbide coating on the surface of Ti6Al4V alloy by using a novel sequential carburization under high temperature, while the titanium cermet femoral head was produced. The titanium cermet phase and surface topography were characterized with X-ray diffraction (XRD) and backscattered electron imaging (BSE). And then the wear behavior of titanium cermet femoral head was investigated by using CUMT II artificial joint hip simulator. The surface characterization indicates that carbon effectively diffused into the titanium alloys and formed a hard TiC layer on the Ti6Al4V alloys surface with a micro-porous structure. The artificial hip joint experimental results show that titanium cermet femoral head could n...

Pr52pto assess the effectiveness of topical negative pressure (tnp) combined with local instillation of biocides against staphylococcus epidermidis and pseudomonas aeruginosa biofilm in vitro

ANZ Journal of Surgery — Mon, 27 Apr 2009 04:00:00 +0100

Introduction: S epidermidis is a recognised major biofilm pathogen and has been implicated in medical device contamination ranging from artificial hip prostheses to breast implants. Pseudomonas aeruginosa is a known pathogen in chronic wounds. Within biofilms, bacteria are enclosed in a polymeric matrix or EPS which cements the bacteria to each other and to the surface. Biofilms act to protect the bacteria from the environment increasing resistance to host immunity, antibiotics and biocides. More recently, we have shown that biofilm occurs on the surface of chronic wounds and that this may have aetiological implications.Method: Staph spp and pseudomonas spp biofilm were grown on glass coupons using the CDC biofilm reactor for 48 hrs and the coupons randomly inserted into the wound model ...

Response to chronic exposure to hexavalent chromium in human monocytes.

Toxicology in Vitro — Fri, 13 Mar 2009 04:00:00 +0100

Authors: Raghunathan VK, Ellis EM, Grant MH Elevated circulating levels of metal ions, particularly chromium, have been measured in the blood of patients with metal hip implants, and this has lead to concerns about the long term safety of the prostheses. For example, depletion of lymphocytes has been reported in vivo in patients with metallic prostheses, and correlated with elevated chromium and cobalt concentrations in blood. However, the implications for immune function are unclear. We have assessed the in vitro responses of U937 human monocytes to chronic exposure (4 weeks) to Cr (VI) ions at concentrations which have been measured in patients with metal artificial hip implants (0.05 - 0.5 muM). Chronic exposure to these low clinically relevant concentrations of Cr (VI) induced a po...

Wear resistance of artificial hip joints with poly(2-methacryloyloxyethyl phosphorylcholine) grafted polyethylene: Comparisons with the effect of polyethylene cross-linking and ceramic femoral heads.

Biomaterials — Fri, 06 Mar 2009 05:00:00 +0100

We reported here that grafting with a polymer, poly(2-methacryloyloxyethyl phosphorylcholine (MPC)) (PMPC), on the PE liner surface dramatically decreased the wear production under a hip joint simulator condition. We examined that the effect of properties of both PE by cross-linking and femoral head by changing the materials on wearing properties of PE. The PMPC grafting on the liners increased hydrophilicity and decreased friction torque, regardless of the cross-linking of the PE liner or the difference in the femoral head materials. During the hip joint simulator experiments (5x10(6) cycles of loading), cross-linking caused a decrease of wear amount and a reduction of the particle size, while the femoral head materials did not affect it. The PMPC grafting abrogated the wear production, c...

Lawmakers Considering Bundled Payments for Medicare Providers

As congressional leaders and the administration of President Obama seek to reform the U.S. health care system, they are looking at changing the nation's approach to paying for treatment for Medicare beneficiaries, the Wall Street Journal reports. The current system functions with payments for physicians according to each procedure they perform, which critics say creates a financial incentive for unnecessary treatments. Alternatives, such as paying a fixed annual rate for each patient, also have been criticized because it could give providers "an incentive to withhold potentially helpful treatments," according to the Journal.Some lawmakers have proposed bundling payments for certain treatments that currently involve separate billable procedures, such as implanting an artificial hip or provi...

Hip Prostheses Safely Fixed

Artificial hip joints are firmly anchored to the patient's damaged bone by screws. But which parts of the bone will safely hold the screws in place? A simulation model is to calculate the strength of the bone from computer tomography images. Hip prostheses do not hold forever. If an implant comes loose, the doctors have to replace it. Most patients need this second operation after about 15 years. By then, the first prosthesis has often worn down the pelvic bone in several places.

Superlubricious surface mimicking articular cartilage by grafting poly(2-methacryloyloxyethyl phosphorylcholine) on orthopaedic metal bearings.

Biomed Res — Mon, 01 Dec 2008 05:00:00 +0100

Authors: Kyomoto M, Moro T, Iwasaki Y, Miyaji F, Kawaguchi H, Takatori Y, Nakamura K, Ishihara K Aseptic loosening of the artificial hip joint with osteolysis due to the wear particles from polyethylene cup has remained as a serious issue. To reduce this wear and develop a novel artificial hip joint system, we produced a superlubricious metal-bearing material: for this, we grafted a 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer onto the surface of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy. For ensuring long-term benefit retention of poly(MPC) on the Co-Cr-Mo alloy for application as a novel artificial hip joint system, several issues must be considered: strong bonding between poly(MPC) and Co-Cr-Mo surface, high mobility of free end groups of the poly(MPC) layer, and high ...

In their laboratory studies, chitosan - a sugar in the cells of crabs and shrimp - repelled bacteria and yeast, effectively preventing these microbes from forming slimy, glue-like layers of infectious cells, known as biofilms, Stewart said. These biofilms account for...

No difference in early cellular response of the pseudo-synovial membrane after total hip arthroplasty: comparison of 3 combinations of bearing materials.

Acta Orthopaedica — Wed, 14 Jun 2006 06:00:00 +0100

Authors: Nygaard M, Elling F, Bastholm L, Søballe K, Borgwardt A BACKGROUND: Wear-resistant bearing materials may hypothetically reduce chronic inflammation in the pseudosynovial membrane as compared to less wear-resistant bearing materials such as polyethylene. We assessed the foreign body response in the pseudosynovial membrane in vivo after total hip replacement. METHODS: 37 patients from a larger prospective randomized trial of 225 patients had biopsies taken arthroscopically from the artificial hip joint (i.e. the pseudosynovial membrane) 1 year after insertion of the implant. All patients had an identical hip prosthesis (Bimetric-RingLoc) except for the bearing materials, which consisted of polyethylene on zirconia, CoCr on CoCr, or alumina on alumina. Histological quantificatio...
