With the development of Birmingham hip resurfacing surgery, many advantages exist for hip resurfacing surgery compared to the traditional full hip replacement.
Smaller Device: Birmingham resurfacing device is chrome cobalt, metal combination. It is smaller than a traditional total hip device. With a smaller device the recovery is quicker.
Reduction in the Bone removed: Birmingham hip resurfacing literally means retreading the bone with a metal prosthesis. Therefore, there is a significant decrease in the amount of bone removed. Only a very small amount of bone needs to be removed. The femur (thigh) bone does not need to be damaged.
Decrease in Complication Rates: Birmingham hip resurfacing surgery greatly reduces the disruption of the joint, therefore providing a shorter recovery period and a decrease in some complications. There is dramatic reduction of dislocation rates and a reduction to the problem of lengthening or shortening of the leg.
Shorter Recovery Time: Most Birmingham hip patients are walking 4 hours after hip resurfacing surgery. Total time spent in hospital is approximately 2 days. Within 2 weeks, most patients are back driving, resuming most of their normal activities. Birmingham hip resurfacing dramatically improves quality of life. For total hip replacement most people remain in hospital for 5-6 days and remain off driving for 6 weeks.
More stable hip: Because hip replacements use a smaller ball (to allow thicker plastic for longer wear) the range of movement is less and the dislocation rate greater (up to 1 in a 25) than a BHR. The hip resurfacing has a dislocation rate of less than 1 in 500 because the ball is not removed and remains the same size as the patient’s original hip. The range of movement is greater. Because the hip is more stable and feels more normal, the recovery is quicker and the function generally better.
Ease of Revision: Because hip resurfacing does not damage the thigh bone, when they fail they can be more easily converted to a total hip replacement. This is important in young patients who wear out total hip replacements, because it saves this procedure as a later option when they are older.
