Metal on Metal Hip replacements - Warning sounded
A recent editorial from the Journal of Arthroplasty warned about the complications of metal on metal Hip replacements and hip resurfacing.
The parts of these metal on metal devices are made from metals like cobalt, chromium and nickel. They gained popularity at the beginning of this decade in the belief that they would last longer than previous implants made of plastic and metal or ceramic. Unfortunately this has not happened and surgeons are starting to revise a high number of these within a short time of putting them in.
The main concern with these devices was the accumulation of metal debris in and around the joint leading to pseudo tumors and groin pain, death of tissues in the joint and loosening of the implant from loss of surrounding bone.
This problem could affect upto one third of patients undergoing a hip replacement in the US. Considering that nearly 250000 people undergo a hip replacement each year in the US, this number could run into thousands.
Further reports in the New York times last week also carried a warning on Hip resurfacing.
This should serve as a warning to reduce the hype for hip resurfacing amongst Americans and Canadians.
Numerous Medical tourism operators canvassing for metal Hip resurfacing would benefit from taking note of this.
