What is the Wright Dynasty Hip?
The Wright Dynasty Acetabular hip implant is a modular cup system designed to accommodate large diameter femoral heads, such as the BFH CoCr heads and BCH large diameter ceramic heads. When used with a metal femoral head, the Dynasty device becomes a metal-on-metal hip replacement system, a device design that has been plagued by reports of adverse local tissue reactions, metal ion poisoning and premature device failure. According to reports, in metal-on-metal hip implants, the ball and cup components can rub against one another during normal use, causing tiny metal fragments to be released into the bloodstream, which can lead to metal ion poisoning and other debilitating complications. The FDA warns, “Over time, the metal particles around some implants can cause damage to bone and/or tissue surrounding the implant and joint […] sometimes referred to as an ‘adverse local tissue reaction (ALTR)’ or an ‘adverse reaction to metal debris (ARMD).’ Soft tissue damage [such as this] may lead to pain, implant loosening, device failure, and the need for revision surgery.”
