Product Name: Birmingham Hip Resurfacing (BHR)
Manufacturer: Smith & Nephew, Inc
Address: 1450 Brooks Road, Memphis, Tennessee 38116
Approval Date: May 9, 2006
Approval Letter: http://www.fda.gov/cdrh/pdf4/p040033a.pdf
What is it? The Birmingham Hip Resurfacing (BHR) System is a metal on metal resurfacing artificial hip replacement system, surgically implanted to replace a hip joint. The BHR is called a resurfacing prosthesis because only the surface of the femoral head (ball) is removed to implant the femoral head resurfacing component.
How does it work? The BHR System has two parts: a socket in the shape of a shallow cup (acetabular component), and a cap in the form of a ball head (femoral resurfacing component).
The cap moves within the cup. The surfaces that rub against each other (the bearing couple) are made from highly-polished metal. This type of bearing couple is called a metal-on-metal bearing couple.
When is it used? The BHR System relieves hip pain and improves hip function by replacing the parts of your hip that have been severely damaged by degenerative joint diseases. Degenerative joint diseases include osteoarthritis, rheumatoid arthritis, traumatic arthritis, dysplasia, or avascular necrosis.
The BHR System is intended for patients who, due to their relatively younger age or increased activity level, may not be suitable for traditional total hip replacement due to an increased possibility of requiring future hip joint revision.
What will it accomplish? The BHR System relieves pain and improves hip function.
When should it not be used? The BHR System should not be used in a patient who:
Your doctor will need complete information about your overall health to determine whether the BHR system is right for you. You should tell your doctor about any health problems, even if they are not related to the hip, because some medicines and diseases (such as diabetes) can affect kidney or bone strength.
