Hip replacement procedures are commonly performed on patients who have lost proper functioning of their hip joint. A hip replacement procedure involves removal of a the head of the thigh bone, and replacing it with a prosthetic ball mounted on a stem which is inserted into the thigh bone. A socket is then placed into the pelvis where the ball fits.
The point at which the ball and socket meet is called the bearing. The size of the bearing strongly influences the rate of wear. Larger bearings offer a more natural range of motion and don’t wear as quickly. For many years the bearing was made out of polyethylene, a medical grade plastic. This spot is often subject to wear, as the joint moves in a natural range of motion. Recently, hip resurfacing techniques have been invented as a better alternative. This involves covering the hip joint surface with metal caps, creating a metal-on-metal joint. Metal-on-metal joints do not wear as quickly as the earlier polyethylene models.
There is currently no data showing that hip resurfacing offers superior functional results compared to other options. The advantages appear to be in potential long term benefits. However, since this is a relatively new procedure, there isn’t enough long-term data available. No single bearing is best for all patients. The best option must be selected on a case-by-case basis.
Due to the fact that DePuy, the manufacturer of the recently-recalled ASR/ASRXL metal-on-metal hip replacement systems, has time and again failed to warn users of the risks associated with its products, such as increased cancer risk, elevated metal ion levels in the blood, and premature device failure, a number of DePuy ASR lawsuits have been filed.
