Resumo(s)
Engineering has a very important role in the development of non-destructive monitoring of
orthopaedical systems allowing the evaluation of its integrity.
Sir John Charnley revolutionized the field of joint arthroplasty in the 1960s with the
development of the total hip replacement. He replaced the diseased hip joint with a steel
femoral component and a plastic acetabular socket cup combination, both fixed into the bone
using a self-curing acrylic cement, polymethylmethacrylate (PMMA) (Browne et al, 2005).
That way, he has restored some of the most problematic joints in the human body.
The placement of the metal implant in the channel open in the femoral bone without using
cement or by mechanical attack, called a non cemented arthroplasty, came into use in an effort
to solve the problem.
