Looking at an Alternative for Total Hip Replacement
Because it is difficult to remove and replace a worn-out or faulty hip device, doctors often advise patients to go away with hip replacement as long as possible. An alternative to total hip replacement, hip resurfacing, offers a more favorable outcome especially to younger patients. Hip resurfacing is an alternate procedure which places a cobalt-chrome metal cap over the femoral head and a metal cup on the acetabulum. Similar to total hip replacement, hip resurfacing devices are developed and marketed by various implant makers. In 2003, DePuy Orthopedics marketed a hip resurfacing system of their own, but due to reports of DePuy hip recall symptoms, they had to issue a voluntary recall.
Hip resurfacing is mostly recommended for younger patients who have severe hip arthritis. Because young patients may need to undergo several revision surgeries, they are advised to undergo hip resurfacing rather than total hip replacement. Possible complications associated with hip revision surgery can be prevented with hip resurfacing and the procedure is thought to preserve more bone.
Comparing total hip replacement and hip resurfacing, the latter have more positive effects. Hip resurfacing involves less bone removal. Instead of removing the entire ball and socket joint, a metal cap is placed around where the cartilage has worn off. By the time patient necessitates a hip revision surgery, it will be easier to manipulate and correct the affected area because there are enough bones left. Furthermore, the femoral head size is large and close to the size of the anatomical head preventing instances of dislocation. It is also possible to prevent leg length discrepancies and toe-in, toe-out faults that may happen with THR, because in hip resurfacing, the entire femoral neck remains in place.
Patient’s anatomy and his doctor determine if he is fitted to have hip resurfacing. The procedure is not recommended for patients who have problems in the bone around the hip joint. These problems include osteoporosis, cysts within the bone and noninflammatory degenerative joint disease. Patients who are morbidly obese are also not advised to undergo the procedure because they have higher rate of developing postoperative complications.
According to some experts, roughly 10-15% of patients who are to have a hip replacement may find hip resurfacing a good alternative. Although the procedure presents lesser complications than THR, it is best to submit yourself to a health care provider for a thorough assessment. It is also important to consider what hip device to use for there are implants that may also cause complications, such as DePuy hip recall.
