HIP RESURFACING: BENEFITS, RISKS AND COST
Controversy aside, the truth is that hip resurfacing arthroplasty is a safe and effective alternative to conventional total hip arthroplasty.
Indeed, the cormet hip resurfacing system is especially recommended for younger and active patients. This surgery can diminish the risk of complications, such as hip dislocation.
However, it may increase the risk of femoral neck fracture. So, hip resurfacing surgery is a great alternative in the right hands and after careful patient selection.
WHAT IS HIP RESURFACING SURGERY?
Metal-on-metal hip resurfacing surgery is not the same as standard total hip arthroplasty. Each of these procedures is a type of hip replacement surgery, but there are important differences.
In a traditional total hip replacement, the round head of the thighbone (femoral head) and the damaged socket (acetabulum) are removed and replaced with metal, plastic, or ceramic implants.
In hip resurfacing, though, the femoral head is not removed. It is carefully cleaned and trimmed. Then, it is capped with a hollow, mushroom-shaped metal covering usually made of cobalt chrome. It is very similar to the capping of a tooth.
After that, the damaged bone and cartilage within the pelvis socket is replaced with a matching metal shell. Like a traditional total hip replacement, this metal socket is wedged directly into the bone.
Hence, this surgery replaces the surfaces of a patient’s hip joint while removing less bone compared to a total hip replacement.
