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… 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
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

Patients and prospective patients are always concerned about the complications that could occur after a hip resurfacing surgery. The typical problems include femur neck fractures, dislocations, loose acetabular cups, improperly positioned acetabular cups, high metal ions, infections, pseudotumors, ALVAL and metalosis.
There has been a lot of discussion among patients on discussion groups about the high metal ion issue and pseudotumors. I am not a doctor or medically trained. I am a Patient Advocate, Hip Resurfacing Patient and Mechanical Engineer. I had the opportunity to attend the Second Annual U.S. Comprehensive Course … Read the rest
The ReCap® Femoral Resurfacing System replaces the diseased surface of the femoral head and is designed to restore the normal anatomy and biomechanical function of the hip joint.The major advantage of the ReCap® Femoral Resurfacing System is its conservative nature. By avoiding medullary canal intrusion, it preserves valuable femoral bone stock, making it a bone-preserving alternative to total hip arthroplasty. A 2006 study published by Girard, J. et al. in the Journal of Bone and Joint Surgery (British) concluded that a group of young patients with femoral hemi-resurfacing were able to maintain a higher average activity level versus a
|The post approach which I employ is traditionally known as the muscle sparing approach and the anterior and anterolateral approaches which is very popular in the U.S and some parts of Europe are the muscle compromising approaches. The muscle here refers to the Abductor group or the muscles which lift your leg sideways and is the most important muscle of the hip. The post approach spares this completely.However some muscle have to be cut in any approach to get access to the hip and in the post approach, one cuts the short ext rotators which are flimsy , small muscles|
The Birmingham (Smith & Nephew, Richards) total HSR was the first to get FDA approval in the US based on an unprecedented FDA decision to approve this implant on the basis of single (developing) surgeon’s foreign data. Cormet 2000 ( Corin Ltd., Stryker) total HSR was the first to be approved based on the usual mechanism of a US run Multi-center FDA study( approval 7/2007, I was the lead investigator). Therefore, there are now 2 implants available in the US that have an FDA indication for total HSR.The Recap/Magnum (Biomet), Conserve Plus (Wright Medical) and ASR (Depuy) are all… Read the rest

Background: There are considerable variations in metal ion levels and metallic wear rates in patients with metal on metal resurfacing. In this in vitro study the effect of design variables of head diameter and bearing clearance and patient variables of cup and head position on metal ion levels and wear rates are were investigated. Methods: Hip joint simulator studies were carried out on size
Cormet is no longer available in the US

|Date:07/01/2007 HEALTHWATCH Revolutionary surgery Hip resurfacing: Fewer risks, more benefits. ARTHRITIS of the hip joint is a common problem in India. It occurs due to damage to the joint from various conditions such as Osteoarthritis (wear and tear arthritis), avascular necrosis (death of the bone due to lack of blood supply), trauma or injury (previous hip fractures), infection, rheumatoid arthritis, ankylosing spondylitis and other diseases. It causes severe pain, stiffness, deformity, decreased mobility and severe disability. In India, hip joint arthritis affects even young people leading to disruption of family and social life, inability to work and difficulty in movement.|
I am 4 days post-op (in 4 hrs) and doing fabulous. We are all different patients, but Mercy Mt Shasta and staff is the best hospital I’ve ever been in and Dr Ure’s office staff is stellar. Don’t let the small town keep you away. The hospital is the cleanest and pristine and nursing staff has a lot of ortho experience. Here’s my story, but feel free to get back to me with questions.
The more knowledge you have going in the more relaxed you will be. Their pre-surgical joint class is an all-day affair but you get to meet … Read the rest
I started taking karate in 1976 under George Annarino of Newark Ohio. The style I train is a mixture of Japanese and Okinawan styles. I hold a 6th degree Black Belt under the Ko-Sutemi Seiei Kan Dojo, and have won 5 NBL World Championships between 1993-1997 while competing on a National Team called “Full Contact”. I also won a gold medal competing on the USA team in Mexico City at the “Mexican Olympic Festival” in 1993.
