Phonophoresis is the use of ultrasound to enhance the delivery of topically applied drugs
What is Phonophoresis? Phonophoresis is the use of ultrasound to enhance the delivery of topically applied drugs. Effectively, medicines contained within or under the ultrasound gel are pushed by the sound waves of the ultrasound and driven deep below the skin. Phonophoretically administered medications can penetrate the body much deeper than those massaged by hand over the surface of the skin. Some medications can be delivered phonophoretically. The process is dependant on many, many factors. |

Outcome dependend on experience – Dr. Shimmin
Outcome of hip resurfacing may be dependent on experience Link By Gina Brockenbrough February 27, 2009 LAS VEGAS — A new study links outcomes of hip resurfacing to the hospital volume of resurfacing cases and, thereby, the surgeon’s experience. To evaluate the impact of operative volume on hip resurfacing outcomes, Andrew J. Shimmin, MBBS, FAOrthA, and colleagues used the Australian Joint Registry to identify nearly 9,000 hip resurfacings performed at 196 hospitals between September 1999 |

Metal-on-metal hip resurfacing with hybrid fixation has been introduced as an alternative to standard total hip arthroplasty, especially for young and active patients. There are few studies in the literature on the midterm results of cementless femoral side resurfacing. The purpose of this study was to present our seven-year clinical results of … Read the rest
Analysis of Cement Penetration in Hip Resurfacing 2007
Link ANALYSIS OF CEMENT PENETRATION IN HIP RESURFACING ARTHROPLASTY R.M. Gillies; J.H. Gan; G.M. Hawdon; and S.J. McMahonMay 2007 Introduction: Prevalence of femoral neck fracture in resurfacing hip arthroplasty continues to question if failure is technique-related or due to the inherent bone quality. This study aimed to correlate cement penetration profile during resurfacing hip with inherent bone density. The hypothesis is that osteoporotic bone is unable to support the prosthesis leading to fatigue failure. Methods: |

Primary Cementless Total Hip Arthroplasty 2014 Study
Archive of failed joint replacements Helps Design New Devices
Archive of failed joint replacements provides tips to building a better hip replacementA study by Hospital for Special Surgery researchers has provided the first comprehensive look at just how metal-on-metal total hip replacements are failing in patients around the country. Made possible by what is thought to be the largest archive of failed joint replacements, the research should help doctors develop a better hip replacement for future patients. The study will be reported at the |

Hip Resurfacing Learning Curve
… Evaluating the first 100 cases of each, showed that the learning curve between planned and achieved implant position was in the order of 50 cases.
The learning curve was longer than estimated and has huge implications, with shortened training programmes and less operative exposure being advocated throughout the world.

No Link between metal hip implants and cancer study 2012
Click below to read full study By Debra Sherman Sep 14, 2012 (Reuters) – All-metal hip implants, which have been shown to have high failure rates and cause a host of other health problems, were not linked to cancer seven years after implantation, new data show. Concerns have grown in the medical community that the so-called metal-on-metal hip implants shed metal particles through wear on their ball-and-socket structure. Many patients who have received the devices |
Dr. Gross responds to the controversy regarding adverse wear in metal-metal bearings 2010
The controversy regarding adverse wear in metal-metal bearings Thomas P. Gross, MD 3/5/2010 I have used over 3000 metal bearings in primary total hip and hip resurfacing as well as revision surgery. I have revised 2 for adverse wear 7 years after implantation. I know that most other high volume hip resurfacing surgeons have a similar experience. The revisions were straightforward and the patient enjoyed the same rapid and complete recovery as if she had |
NIH researchers study metal-on-metal hip implant lubricant
