Metal-on-Metal Hip Replacement Devices Have Higher Risk Of Complications

by Colbert Cooper Hill Attorneys

MedPage Today says that a new British study concluded patients who received metal-on-metal (MOM) total hip replacements much more commonly had to undergo revision surgery within five years due to complications and/or problems than those with other types of implants.

Researchers with the National Joint Registry of England and Wales collected data from more than 400,000 case files of patients who underwent total hip replacement surgeries between the years of 2003 and 2011. Of those cases, 31,171 involved metal on metal replacements.

Results showed that MOM hip replacements had a 6.2 percent cumulative risk of revision within five years, versus 3.3 percent for ceramic-on-ceramic and 1.8 percent for metal-on-polyethylene devices.

Women, especially younger women, with MOM hip replacements tended to be at a higher risk of device malfunction within the five-year time frame as well. Women aged 55-years-old had a 4.8 percent risk of revision versus a 70-year-old woman’s 2.6 percent risk with the same device. Women also tended to be at a greater risk of device malfunction than men.

Problems associated with hip replacement malfunctions include inflammation and infection from particles to ions from metal particles being absorbed into the body.
