Washington, Nov 4: While hip resurfacing is considered to be the modern day alternative for total hip replacement, researchers at Rush University Medical Center have suggested that the procedure is not ideal for everyone - and a patient''s age and gender is the key to the operation''s success.

For the study, the scientists examined data for 537 hip resurfacing surgeries performed in the U. S. using a hip resurfacing device, called the Birmingham Hip Resurfacing implant, recently approved by the Food and Drug Administration (FDA),

They found that the majority of serious complications occurred in women of all ages and men over the age of 55.
