Tribological Considerations in Primary and Revision Metal-on-Metal Arthroplasty
- Characterization of the Running-in Period in Total Hip Resurfacing Arthroplasty: An in Vivo and in Vitro Metal Ion Analysis. Heisel, Christian; Streich, Nikolaus; Krachler, Michael; Jakubowitz, Eike; Kretzer, J. Philippe // Journal of Bone & Joint Surgery, American Volume;Aug2008 Supplement 3, Vol. 90-A, p125
Background: Metal-on-metal total hip resurfacing arthroplasty is increasingly being performed in young and active patients. Preclinical in vitro testing of implants is usually performed with use of hip simulators, and the serum metal ion concentration is determined for the purpose of monitoring...
- Design Considerations and Life Prediction of Metal-on-Metal Bearings: The Effect of Clearance. Tuke, Michael A.; Scott, Gareth; Roques, Anne; Hu, Xiao Q.; Taylor, Andrew // Journal of Bone & Joint Surgery, American Volume;Aug2008 Supplement 3, Vol. 90-A, p134
Background: Clinical observations suggest that metal-on-metal arthroplasties that have been implanted for more than twenty years do fail. It is proposed that there are not two, but three distinct phases of wear life for any metal-on-metal implant system: bedding-in, steady state, and end point....
- Wear Rate of Highly Cross-Linked Polyethylene in Total Hip Arthroplasty: A Randomized Controlled Trial. McCalden, Richard W.; MacDonald, Steven J.; Rorabeck, Cecil H.; Bourne, Robert B.; Chess, David G.; Charron, Kory D. // Journal of Bone & Joint Surgery, American Volume;Apr2009, Vol. 91-A Issue 4, p773
Background: Highly cross-linked polyethylene was introduced for clinical use in total hip arthroplasty with the expectation that it would exhibit less wear when compared with conventional polyethylene. The purpose of this study was to report the clinical and radiographic results, after a minimum...
- Tribology and Wear of Metal-on-Metal Hip Prostheses: Influence of Cup Angle and Head Position. Williams, Sophie; Leslie, Ian; Isaac, Graham; Jin, Zhongmin; Ingham, Eileen; Fisher, John // Journal of Bone & Joint Surgery, American Volume;Aug2008 Supplement 3, Vol. 90-A, p111
Background: Clinical studies have indicated that the angular position of the acetabular cup may influence wear in metal-on-metal total hip bearings. A high cup angle in comparison to the anatomical position may lead to the head being constrained by the superior lateral surface and rim of the...
- Clinical digest. Trial proves apremilast is effective long-term treatment for psoriasis. // Nursing Standard;10/10/2012, Vol. 27 Issue 6, p14
The article discusses research in the article "Efficacy of Apremilast in the Treatment of Moderate to Severe Psoriasis: A Randomised Controlled Trial" by K. Papp et al. which found that the drug apremilast is effective for the long term treatment of psoriasis.
- Clinical digest. Evidence supports wider use of tranexamic acid in traumatic bleeding. // Nursing Standard;10/10/2012, Vol. 27 Issue 6, p15
The article discusses research in the article "Effect of Tranexamic Acid on Mortality in Patients With Traumatic Bleeding: Prespecified Analysis of Data From Randomised Controlled Trial" by I. Roberts et al. which found that tranexamic acid is safe and effective in treating traumatic bleeding.
- Clinical digest. Most people treated for schizophrenia experience no lasting improvements in health. // Nursing Standard;4/18/2012, Vol. 26 Issue 33, p14
The article discusses research which was published in the article "Sustained Favourable Long-Term Outcome in the Treatment of Schizophrenia: A 3-Year Prospective Observational Study" by G Cuyun Carter et al. and found that most people treated for schizophrenia experience no lasting improvements...
- PERSPECTIVE. Hee Kit Wong // Orthopedics Today;Jul2011, Vol. 31 Issue 7, p26
The author comments on the study by Miyako Suzuki wherein Suzuki found that, in determining whether using local bone graft is as effective as iliac crest bone graft in case of L4 degenerative spondylolisthesis, there are fusion rates of 90% and 85%, respectively, in single-level instrumented cases.
- Clinical digest. Surgery for epilepsy can enhance patients' overall long-term quality of life. // Nursing Standard;3/7/2012, Vol. 26 Issue 27, p18
The article discusses research which was reported in the article "Impact of Epilepsy Surgery on Seizure Control and Quality of Life: A 26-Year Follow-Up Study" by H. S. Mohammed et al and found that surgery for epilepsy can enhance patientsâ€™ overall long-term quality of life.
