NEW YORK SURGEON INTRODUCES UNIQUE ALTERNATIVE TO
TOTAL HIP REPLACEMENT


Innovative Birmingham Hip Resurfacing™ System preserves bone and joint stability for young, active patients

White Plains, NY. (September 30, 2006) - Steven B. Zelicof, MD, Ph.D., of Specialty Orthopaedics, PLLC is among one of the first surgeons in this country who has been trained in the remarkable new Birmingham Hip Resurfacing (BHR) technique. Rather than replacing the entire hip joint, as in a total hip replacement, hip resurfacing simply shaves and caps a few centimeters of bone within the joint.

The Birmingham Hip's bone-conserving approach preserves more of the patient's natural bone structures and stability, covering the joint's surfaces with an all-metal implant that more closely resembles a tooth cap than a hip implant. This approach reduces the post-operative risks of dislocation and inaccurate leg length, and because the all-metal implant is made from tough, smooth cobalt chrome, it has the potential to last longer than traditional hip implants.

"This is one of the most exciting procedures I've seen in years," explains Dr. Zelicof. "I see hip resurfacing as the ideal solution for many of my young, active patients who suffer from hip pain. As my patients are getting younger and younger, and are staying physically active much later in life, I've needed an alternative to total hip replacement that accommodates their age and lifestyle. The Birmingham Hip Resurfacing System is that alternative."

The Birmingham Hip implant is intended for patients suffering from hip pain due to osteoarthritis, dysplasia or avascular necrosis, and for whom total hip replacement may not be appropriate due to their increased level of physical activity. For this reason, most surgeons feel it will be ideal for patients under age 60 who live non-sedentary lifestyles.

Dr. Steven B. Zelicof has been in orthopedic surgical practice since 1990. He specializes in reconstructive surgery of the hip and knee. Dr. Zelicof is a leading surgeon in treating young active patients with hip and knee arthritis and has been involved in joint replacement research and total joint prosthetic design. Dr. Zelicof has been performing metal on metal hip resurfacings since the 1990s.

About the Birmingham Hip Resurfacing implant
While the BHR implant closely matches the size of a patient's natural femoral head (hip ball), it is substantially larger than the femoral head of a traditional total hip replacement implant. This increased size translates to greater stability in the new joint, and it decreases the chance of dislocation of the implant after surgery. Dislocation is a leading cause of implant failure after total hip replacement.

Total hip replacement involves the removal of the entire femoral head and neck. The Birmingham Hip resurfacing technique, however, leaves the head and neck untouched. It is this neck length and angle that determines the natural length of a patient's leg after surgery, and since it is not removed and replaced with an artificial device during the resurfacing procedure, there is a greater likelihood of maintaining accurate leg length.

The Birmingham Hip implant is an all-metal ball and socket joint. Traditional hip replacements use a metal ball and a plastic socket. As would be assumed, this plastic socket wears down over time, and may need to be replaced surgically. In fact, it is a leading cause of follow-up surgeries. All-metal total hip replacements reduce joint wear by 97-percent compared to total hip implants containing these plastic sockets.
