BIRMINGHAM HIP (BHR◊) Resurfacing System
A high-performance alternative to total hip replacement
Patients who suffer from hip pain due to arthritis, dysplasia or avascular necrosis may benefit from the bone-conserving approach of the BIRMINGHAM HIP Resurfacing System (BHR Hip), the world's leading hip resurfacing system.
Unlike total hip replacement, the BHR hip resurfaces just a few centimeters of bone, preserving your original joint. The BHR hip is not unlike a cap for a tooth.
Because this technologically advanced surgical procedure resurfaces, rather than replaces, the end of your femur (thighbone), you may participate in physical activity with an implant that is potentially longer-lasting and more stable than total hip replacements.
Candidates for Hip Resurfacing
Hip resurfacing is intended for male patients who are under 65 years of age and in need of a hip replacement. As with all treatments, please discuss with your options with your doctor to find out if hip resurfacing is appropriate for you.
The BHR Hip was approved for use in the United States by the Food and Drug Administration in 2006, but has been implanted around the world more than 170,000 times since 1997. Surgeons who offer this implant to patients have undergone specialized training.
The benefits to patients of the BHR Hip technique and implant are significant. The implant's head size, its bearing surfaces and its bone-sparing technique make it a preferred choice for active patients.
While the implant's rate of survivorship is comparable to standard total hip replacements after five years, these three key advantages set the resurfacing technique and implant apart from its total hip replacement counterparts.
While the implant closely matches the size of your natural femoral head (hip ball), it is substantially larger than the femoral head of most total hip replacements. This increased size translates to smaller chance of dislocation of your implant after surgery.
The Bone Conservation
The BHR Hip implant conserves substantially more bone than a total hip replacement. Since it preserves your natural femoral neck and most of your femoral head, concerns about leg length discrepancy are dramatically reduced. Also, should you need the implant replaced at some point in the future, you are a candidate for regular total hip replacement surgery as opposed to needing a more traumatic and complex revision surgery as is often the case when a traditional hip replacement needs to be replaced.
Total hip replacement requires the removal of the femoral head and the insertion of a hip stem down the shaft of the femur. Hip resurfacing preserves the femoral head and the femoral neck. During the procedure, your surgeon will only remove a few centimeters of bone around the femoral head, shaping it to fit tightly inside the BHR Hip implant.
Your surgeon will also prepare the acetabulum for the metal cup that will form the socket portion of the ball-and-socket joint. While the resurfacing component slides over the top of the femoral head like a tooth cap, the acetabular component is pressed into place much like a total hip replacement component would be.
There are potential risks with hip resurfacing surgery such as fracture, infection, loosening, dislocation and wear that may result in the need for additional surgery. The results and physical activities of this patient may not be representative of the results and physical activities that you may experience following surgery. BHR is contraindicated for all female patients. Do not perform high impact activities such as running and jumping during the first post operative year while the bone is healing. Early device failure, breakage or loosening may occur if you do not follow your surgeon's limitations on activity level. Early failure can happen if you do not guard your hip joint from overloading due to activity level, failure to control body weight, or accidents such as falls. Hip resurfacing surgery is intended to relieve hip pain and improve hip function. Talk to your doctor to determine what treatment may be best for you.
