Mr Jeremy Latham, Consultant Orthopaedic Surgeon, discusses the recent media coverage of the metal-on-metal hip replacements and offers information and advice if you have concerns.
"The DePuy ASR Metal-on-Metal (MoM) hip replacement was recalled last year due to a higher than anticipated failure rate. We are aware that recent media attention may well be heightening our patients’ concerns so I would like to provide some reassurance and advice. The vast majority of patients have no cause for concern because the particular DePuy ASR device has not been used by any consultants in Southampton. However, there are other, similar devices that may require monitoring. We recognised problems with some types of hip replacements well over a year ago and are managing our patients accordingly. If you have concerns, I recommend that you get in touch with your consultant who will be happy to advise you on what to do."
The metal hip has been commonly used for hip replacements or in hip resurfacing work, where metal is placed on the top of the thigh bone with the hip socket lined with metal. For many patients the Metal-on-Metal hip has proven very successful. However where the metal hip is not properly aligned, the two metal plates in the hip joint rub together causing metal debris or chromium ions to be released into the bloodstream resulting in tissue damage and non-cancerous tumours to develop. This in turn can cause patients to suffer hypersensitive reactions and should this be the case, their consultant may well recommend a revision.
