The NJR’s 8th Annual Report shows females are most at risk from problematic hip devices. Performance for the controversial metal-on-metal (MoM) hip replacement devices continues to create cause for concern, particularly in women. Revision rates (how likely it is that a patient will need an operation to remove and usually replace a prosthesis) for the devices are by far the highest for the two main categories of MoM hip devices.
In 2010, figures from the NJR led to the worldwide recall of the DePuy ASR metal-on-metal device, which had proved particularly poorly performing.
Perhaps unsurprisingly then, use of MoM devices continue to decline. NJR statistics from 2006 and 2007 showed MoM devices as being used in 15% of procedures on the registry. This had fallen to 10% by 2009, and this year’s Annual Report (covering statistics from 2010) shows another dramatic fall to 5% of procedures recorded on the NJR using metal-on-metal devices.
