Hip resurfacing
Hip resurfacing provides a bone conserving solution for the younger, more active patient in line with their increased demands for higher activity. Whereas with conventional total hip replacements the head of the thigh bone is removed and replaced, in a hip resurfacing, only the diseased or damaged surfaces of the hip joint – the femoral head (‘ball’) and the acetabulum (‘socket’) – are replaced with metal surfaces. This procedure is therefore much more bone conserving than a conventional total hip replacement, as the head of the femur is simply reshaped and resurfaced, rather then being removed. Should the implant need replacing at any point in the future, this may make revision surgery easier, which means that it is indicated for patients who are at risk of requiring more than one hip joint replacement over their lifetime.
Other advantages for the younger patient stem from the materials used. As both components or ‘bearing surfaces’ are made from metal (rather than plastic), the resurfacing system may last longer and therefore, may be more suitable for patients with higher levels of activity. The femoral bearing is also a larger diameter than is used in a conventional total hip replacement – closer to the size of the head of the natural femur. This means that it is less likely to dislocate than the smaller diameter bearing of a total hip replacement.
In recent years the use of ‘minimally invasive’ techniques has become more widespread, with surgeons making smaller incisions, causing less disruption to the soft tissues around the hip. The instruments used with Cormet, Corin’s advanced hip resurfacing system, are designed to allow the surgeon to implant the resurfacing using small incision techniques.
If you are a suitable candidate for hip resurfacing, it is possible that you will be able to return to relatively normal levels of activity – many resurfacing patients have been able to take part in modest recreational sporting activities with their new hip. However, hip resurfacing is not suitable for everyone (for example, people with low bone density or osteoporosis), although this type of operation may usually be recommended for younger patients (typically below the age of 65) with a relatively active lifestyle. Your surgeon will discuss this with you and advise whether or not this type of operation is suitable for you.
