Since the first attempt at total hip replacement surgery in the early 20th century, the procedure has become one of the most common and effective types of surgery. According to the UK National Joint Registry (NJR), in 2011 71,672 hip replacement procedures were undertaken.
Although early hip replacement systems involved metal-on-metal articulations, by the 1970s, these models had been rejected in favour of hip systems using other materials such as polyethylene. In the 1990s metal-on-metal bearings began to be reintroduced as these systems were thought to be lower wearing and larger head sizes presented a lower risk of dislocation. Metal-on-metal hip resurfacing also offered the potential advantage of bone preservation.
According to the 2012 NJR annual report, all metal-on-metal total hip replacement systems have very poor implant survivorship when compared with other kinds of total hip replacement systems.
The UK NJR also concluded that resurfacing hip systems have a higher failure rate than total hip replacement systems (except when compared with metal-on-metal total hip replacement systems).
The main concern with metal-on-metal components is the release of metal ion particles into the body, which can lead to severe soft tissue reactions, described by the orthopaedic community with terms such as metallosis, ‘ALVAL’, adverse reactions to metal debris (ARMD) and pseudo-tumours.
