Are you suffering after your hip implant revision surgery? A high percentage of patients implanted with monoblock metal-on-metal (MoM) total hip implants like the DePuy ASR suffer from early complications after revision surgery.
Louis Stryker, M.D. and his colleagues understand that the reasons metal-on-metal hip implants fail are quite unique compared to conventional hip replacements. These include metallosis and other adverse tissue reactions. Because of the distinct failure mode of metal-on-metal devices, Dr. Stryker et al. reviewed potential complications following revision. The implants they investigated were from Biomet, DePuy, Wright Medical and Zimmer.
The complications they found included:
- aseptic loosening
- deep infection
- acetabular fracture
- superficial infection
- infected hematoma
- delayed wound healing
They found that older patients are at an increased risk for early complications after revisions while there were no particular differences in sex or time between implant and revision surgery. If you or a loved one have been implanted with one of these devices and have undergone a revision surgery, please call our attorneys for a complementary case evaluation.
