Even after a medical product passes rigorous testing by the U.S. Food and Drug Administration (FDA), unforeseen problems often arise that lead to injuries among patients. Over the past several years, several hip replacement systems brought to market by various manufacturers have faced FDA recalls due to component failures requiring replacement surgery.
The FDA has ordered a review of all metal-on-metal hip implants due to mounting patient complaints. Reported symptoms include pain, swelling, and difficulty walking. Problems with the hip implants include, but are not limited to, loosening, metallosis (i.e. tissue or bone death), fracturing and/or corrosion and fretting of these devices, which require revision surgery. Many patients that require revision surgery due to these devices suffer significant post-revision complications. We are investigating all cases involving metal-on-metal hip implants.
The primary hip replacement systems that are known to cause medical injuries or problems resulting from corrective surgery includes:
- Stryker Rejuvenate and ABG II Hip replacements
- Depuy ASR hip system
- Smith & Nephew SMF™ and REDAPT™ Revision Femoral Hip Systems
- Zimmer Durom Cup metal-on-metal implant
Symptoms To Watch Out For
The most common types of injuries or medical problems reported as a result of hip system implant failure include:
- Skin rashes near the implant site
- Cardiomyopathy — disease of the heart muscle
- Changes to the neurological system, including problems with eyesight and hearing
- Depression and cognitive disability
- Kidney failure
- Fatigue, unexplained weight gain, sensation of feeling chilled
In addition to medical symptoms related to the failed implant in the body, there may also be medical injuries resulting from the corrective surgery.
