Birmingham Hip Resurfacing (BHR) is a less invasive alternative to total hip replacement for younger or more active patients suffering from hip arthritis or other sources of hip pain. If these patients undergo hip replacement in their current state, they will likely outlive their hip replacement and need to undergo a second procedure, which is much more complex and risky. BHR helps postpone the need for total hip replacement by replacing only the damaged surfaces of the joint, preserving healthy bone.
During the BHR procedure, the femoral head is smoothed to receive the implant device, while the socket of the joint is properly shaped for placement of the resurfacing cup. The devices are then precisely placed in the joint and secured with bone cement. A drainage tube may be inserted for a few days after surgery.
Patients will need to undergo physical therapy after this procedure in order to restore strength and function to the joint. Since this is a relatively new procedure, long-term results are still unknown, but this device has been proven successful for at least five years for almost all patients.
The hip is a "ball-and-socket" joint where the "ball" at the top of the thigh bone (femur) fits inside the "socket" in the pelvis (acetabulum). A natural substance in the body called cartilage lubricates the joint. When the bone and/or cartilage of the hip becomes diseased or damaged from arthritis, hip fractures, bone death or other causes, the joint can stiffen and be very painful. A total hip replacement may be recommended for patients who experience severe hip pain and whose daily lives are affected by the pain.
In a total hip replacement, the diseased bone and cartilage are replaced with a metal ball and plastic cup. The artificial joint, called a prosthesis, may be cemented in place, may be cementless, or may be a hybrid of both. The surgery takes from two to four hours, followed by another few hours spent under observation in a recovery room. Patients usually enjoy immediate relief from joint pain after the surgery.
Physical therapy starts as soon as the first day after surgery with the goal of strengthening the muscles and preventing scarring (contracture). Therapy begins with the patient sitting in a chair and progresses to stepping, walking and climbing stairs, first with crutches or walkers and then without supportive devices. Occupational therapy and at-home exercises help patients learn how to use the prosthesis in everyday activities.
Most patients who undergo hip surgery achieve successful relief from their condition, including pain relief, restored function and an improvement to their overall quality of life. Total hip replacement is successful in over 95% of well-selected patients. On average, replacements last 15-20 years. Some patients enjoy full use of the prosthesis after 25 years or longer. The results of each individual hip replacement procedure will vary depending on the patient's age, severity of condition and overall health.
While hip replacement is considered a safe procedure for most patients, there are certain risks involved with any kind of surgery. Some of these risks may include:
These risks are considered rare and can be further reduced by choosing an experienced and skilled surgeon.
