Hip Resurfacing vs Hip Surface Replacement
Hip resurfacing involves replacing damaged surfaces in the hip joint with metal surfaces. This procedure can be useful for patients under 65 with advanced hip disease
 
Hip resurfacing surgery is an alternative to standard hip replacements for patients with severe arthritis. In hip resurfacing surgery, the implant is smaller, and less normal bone is removed. Hip resurfacing is gaining interest, especially in younger patients
 
Hip Resurfacing Operation

Mr Hugh Blackley was the first to pioneer modern hip resurfacing in New Zealand in 2003. He was trained by the designers and remains a strong advocate for the technique. He has done the most hip resurfacings of any surgeon in New Zealand and currently does 2-3 per week. He remains the most experienced surgeon in New Zealand in the procedure and is on the Australiasian Surgical Advisory Panel for Birmingham Hip Resurfacing.

Hip Resurfacing surgery is approximately 90 minutes of set up and operating time. There is approximately 1 hour in the recovery room after surgery. Hip resurfacing surgery requires the removal of the diseased bone only. This means, the bone removed is minimized to 4-5mm from the head of the femur and approx 4-5mm from the acetabulum.

The incision is approximately 15-20cm in length and it runs over the outer edge of your hip joint. The scar line may not be completely flat immediately after surgery. This will settle down a few weeks after surgery. The operation itself is performed with the patient of their side. The surgical wound is closed with absorbable sutures.

Most surgery is carried out under an epidural spinal injection with sedation. It is safer way with a quicker recovery. You will not feel anything and can be fully asleep with an epidural. The epidural is removed 1-2 days after surgery. Post operative pain is well controlled with the epidural and oral medications. We try to avoid strong painkillers such as morphine because of side effects and they are not usually necessary. For most people the pain is less than that which they experience most days prior to surgery.

Hip Resurfacing is a particularly attractive option an alternative to total hip replacement for younger arthritic and active patients as the design permits a greater range of movement and a lower risk of dislocation. The surgery saves bone on the femoral side but removes slightly more bone on the socket side.

Unlike traditional hip replacement, resurfacing does not require removing the head of the femur (the bone in the upper leg) to replace it with an artificial ball. Instead, the head is reshaped and capped with a prosthetic that, as in the traditional procedure, fits into a man-made lining in the socket. Resurfacing uses a bigger ball, which makes dislocation less likely and gives the joint the ability to handle greater stress. Preserving the top of the femur is also an advantage if the hip requires subsequent work, which becomes more likely as the average age of hip patients, many of them quite active and determined to stay that way, falls.

Birmingham Hip Resurfacing

There has been some concern that the metal ions released in a resurfacing are not suitable for young women considering child bearing and in patients with distorted anatomy or osteoporotic bone, the procedure is not ideal.  The reasons for this are failure of fixation or a fracture beneath the femoral component. Should either of these complications occur, then the operation will need to be re-done to a more typical hip replacement.
