Metal ion release following hip replacement not strongly related to patient activityRead Complete Article by Clicking Here The amount of patient activity following metal-on-metal hip resurfacing arthroplasty seems to show little correlation to metal ion release, according to study presented here. Amir Kamali, PhD, presented his team’s findings at the 56th Annual Meeting of the Orthopedic Research Society.Kamali reported that his group looked at 25 consecutive male patients who underwent a unilateral, 50-mm diameter metal-on-metal hip resurfacing……”I should mention here that at 1, 2, and 4 years, the average metal ion levels were similar between these implants, meaning they had gone well into their steady state,” Kamali said…

Dear Dr. Bala,I apologize for seeming to have neglected or ignored you. I have begun this missive on several occasions, only to stumble over my own limitations. I know I promised you a recommendation you might be able to use on your web site. You have my permission to use any or all of this email in any way you see fit.I have struggled to find the words necessary to describe how Dr. Bala has changed my life. At 44 years of age, to hear the words from a U.S. physician, “You have osteoarthritis in your left hip and I could have you approved for a total hip replacement surgery by Monday”, was nothing short of terrifying. He told me the determining factor… Read the rest
I had a BMHR 4 weeks ago. The operation was broadcast live to the States as interactive training for 100 surgeons, so hopefully it is intended to be available elsewhere too, though when we don’t know, as it’s still in the early trial stage.I was born with CHD ..my femoral head was very soft because it wasn’t in the socket, hadn’t been weight bearing and had lost some of its calcium. So I wasn’t suitable for a BHR but did feel lucky to get a BMHR instead (with a dysplasia cup), because if I had gone anywhere else it would have been a THR.Everything is going really well and I can’t believe the difference it has made to me. But I’m very aware
|Surgeon Volume Influences Rate of Total Hip Replacement Revision – A DGReview of :”Early failures of total hip replacement: Effect of surgeon volume” Arthritis & Rheumatism 04/28/2004 By Emma Hitt, PhDPatients treated by surgeons who perform few total hip replacements (THR) per year are more likely to undergo revision THR, particularly within the first 18 months of surgery, than are patients treated by high-volume surgeons, a new report suggests.Hip prostheses function well for up to 20 years in at least 80% of patients, and failure rates are less than 1% per year.

November 16, 2011
The retrospective study, which analyzed 925 hip resurfacings
performed by Edwin Su, MD, between 2004 and 2009 with a
minimum follow-up of 2 years, looked at three implants:
Wright Medical’s Conserve Plus Total Resurfacing Hip System,
Biomet Orthopedics’ ReCap Femoral Resurfacing System and
Smith & Nephew’s Birmingham Hip Resurfacing System. Conserve
Plus and the Biomet ReCap were used as part of clinical
trials, while the Birmingham hip was used after FDA approval
of the implant in 2006. Clinical scores and radiographs were
obtained at 1 month, 3 months, 1 year, and every subsequent
year. The hips in the study had a minimum of 2 year follow
up, both radiographically and … Read the rest
Resurfacing patients had gait characteristics that were comparable to normal hips. Although standard hip replacements had markedly improved gait parameters when compared to osteoarthritic hips they never approached resurfacing or normals. “

Can I have an MRI after I had a hip resurfacing? This is a question many people ask after having a hip resurfacing. This is Dr. Rubinstein’s answer:
MRI is perfectly safe with any orthopaedic implant (joint replacements, fracture hardware screws and others). The implants may degrade the picture quality in the areas right near the implants but no harm will come to the implants or the surrounding bone.Pacemakers are another story and are not safe with MRI. Other things that can be problematic are metal filings in the eye and vascular clips placed within 6 months.Scott Rubinstein M.D. www.hiportho.com
Derek McMinn addresses the recent Concerns about Hip Resurfacing and Metal on Metal (MoM) implants Interview by Vicky Marlow

Internationally renowned hip and knee surgeon and designer and pioneer of the Birmingham Hip Resurfacing, Derek McMinn addresses concerns about Hip Resurfacing and Metal on Metal (MoM) implants.
Derek McMinn has done over 6000 total hip surgeries and over 3,500 MoM Hip Resurfacings. His 10 year survivorship for the BHR (Birmingham Hip Resurfacing)in a series of 3095 performed up until December 2009 is 97% from all patients. His first metal/metal resurfacing prototype was implanted in 1991, and the current design, the first BHR was implanted in July 1997 and has not changed in any way since then.

MANCHESTER – Researchers here reported that adverse soft tissue reactions following metal-on-metal hip arthroplasty are typically due to increased wear of the bearing surfaces, and patients with smaller femoral heads may be particularly susceptible to these complications.In an independent center study, David Langton, FRCS, and colleagues in the Joint Replacement Unit at the University Hospital of North Tees in Stockton, England, reviewed 155 Birmingham Hip resurfacings (BHR, Smith & Nephew) performed between 2002 and 2009 (mean follow-up, 60 months). They also studied 420 articular surface replacements (ASRs) and 75 total hip replacements using ASR XL implants (both DePuy Orthopaedics) with S-ROM stems (DePuy Orthopaedics) with a mean follow-up of 35 months…

Yes, it is true that minimally invasive approach has been proven not to have great benefits over a conventional incision in terms of blood loss, pain , or speed of recovery in the same surgeons hands. It is only of cosmetic value.All studies to investigate this have been done on two groups of patients in which a single surgeon employs the two approaches in the diff groups. When a surgeon who is capable of doing a minimally invasive approach does a conventional approach it is logical that the conventional technique will be only marginally bigger and therefore advantages do not show up in studies. However, if a minimally invasive approach of a surgeon is compared with a conventional approach of another surgeon who

The anterior vs. posterior debate isn’t going to be resolved by one study of electrode blood flow. Most surgeons would agree that blood flow to the femoral head (most of which comes backwards via the femoral neck) is theoretically better preserved through an anterior approach. Much of this info comes from the work of Ganz, who did a lot of cadaver dissection to prove this. Having said that, there doesn’t seem to be any evidence whatsoever that one approach or the other leads to a higher incidence of the femoral head dying after resurfacing surgery (so called ”avascular necrosis”).
McMinn and Treacy, who have together the largest series of resurfacings in the world, both use the posterior approach, and there

Prednizone Side Effects – Should I Be Worried if I Take this Drug? By Nathan Wei
Prednizone- the correct spelling is “prednisone”- is a commonly used oral glucocorticoid medicine.
The adrenal glands manufacture a natural form of glucocorticoid. Glucocorticoids are responsible for many functions in the body including maintenance of blood pressure, proper use of sugar, protein, and fat metabolism, response to stress, and many other tasks.
Glucocorticoids manufactured by the body are referred to as endogenous steroids- meaning a person’s own body makes these steroids.
When steroids are taken in from the outside either by mouth, intramuscularly or intravenously, they are referred to as exogenous steroids. Taking glucocorticoids orally or intravenously can reduce the ability of the person’s own adrenal glands to continue to
