Medical professionals have brought up evidence showing that hip implants are less likely to be successful in women! Researchers in California who studied more than 35,000 cases of artificial hip implants found that women have a slightly higher risk of implant failure compared with men regardless of the type of device that was implanted. Scientific researchers have underlined that though the overall number of failures is relatively small, the reason that they occur more frequently in women than in men is not entirely clear. Nonetheless, biologists have demonstrated that women have smaller joints and bones than men, thus, women need smaller artificial hips. Consequently, medical researchers have detected that devices with a smaller femur head - the ball shaped part of the ball-and-socket joint in an artificial hip - are more likely to dislocate and requiresurgical repair...
