sentences:  Patient suitability for hip resurfacing is decided by the patient's anatomy and the patient's surgeon.Hip resurfacing is generally more suitable for younger patients who are not morbidly obese, are clinically qualified for a hip replacement (determined by the doctor), have been diagnosed with noninflammatory degenerative joint disease, do not have an infection, and are not allergic to the metals used in the implant.Hip resurfacing should not be used on patients who have severe bone loss in their femoral head, those with large femoral neck cysts present (typically found at surgery) or cysts that are close to the head neck junction, or patients who have poor bone stock or osteoporosis.
