Total hip arthroplasty: a still evolving technique
Abstract
It has been advocated that total hip arthroplasty (THA) is probably the most successful surgical intervention performed in Medicine. In the 1960s, Sir John Charnley not only introduced, but also modified and improved the technique of cemented arthroplasties. The concepts on biological fixation established by Pillar and Galante served as the foundation for the development of uncemented implants that are now used worldwide. Currently, THA is a worldwide widespread surgery performed on millions of people. However, keeping abreast of the large number of information available on these procedures, especially on implant fixation, designs, different tribological pairings, and the long-term results can be challenging at times. This article is a brief update on the main aspects of THA.
A artroplastia total do quadril (ATQ) é uma das cirurgias de maior sucesso na história da medicina. Nos anos 1960, Sir John Charnley introduziu e aperfeiçoou as artroplastias cimentadas. Pillar e Galante estabeleceram os conceitos da fixação biológica, base para o desenvolvimento das artroplastias não cimentadas. Atualmente, a ATQ é uma cirurgia mundialmente difundida e feita em milhões de pessoas. No entanto, o grande número de informações disponíveis sobre as artroplastias, especialmente quanto à forma de fixação do implante ao osso, aos diferentes designs das hastes e dos acetábulos, aos diferentes pares tribológicos e aos resultados no longo prazo por vezes dificulta a tomada de decisão. Este artigo é uma breve atualização sobre os principais aspectos da ATQ.
