In vitro fatigue failure of cemented acetabular replacements: a hip simulator study.
Although hip simulators for in vitro wear testing of prosthetic materials used in total hip arthroplasty (THA) have been available for a number of years, similar equipment has yet to appear for endurance testing of fixation in cemented THA, despite considerable evidence of late aseptic loosening as one of the most significant failure mechanisms in this type of replacements. An in vitro study of...
متن کاملAutomated assessment of polyethylene wear in cemented acetabular components using anteroposterior radiographs of total hip replacements
Polyethylene wear in the acetabular components of hip prostheses is implicated in loosening and failure. Radiographic measurement of wear is used to identify patients at risk and to assess prosthesis designs. This paper focuses on analysis of prostheses with cemented acetabular cups from anteroposterior (AP) radiographs. The articular surface of the femoral head and the acetabular rim marker ar...
متن کاملSurvivorship of cemented knee replacements.
The survivorship method of analysis has been used to compare the failure rate and overall success of 1,430 cemented primary total knee arthroplasties performed at The Hospital for Special Surgery over a 15-year period. There were 224 total condylar prostheses with a polyethylene tibia, 289 of the posterior stabilised type with an all polyethylene tibia, and 917 posterior stabilised with a metal...
متن کاملCemented and non-cemented replacements of the trapeziometacarpal joint.
We performed 88 primary ball-and-socket arthroplasties of the trapeziometacarpal joint in 84 patients (69 women and 15 men) with a mean age of 61 years (37 to 81). Cemented de la Caffinière prostheses were implanted in 43 joints from 1988 to 1991 and 45 cementless Ledoux implants were used between 1992 and 1994. Of the 61 surviving prostheses still in situ, 51 were reviewed clinically and radio...
متن کامل‘Explanting’ the well-fixed, cemented acetabular implant
BACKGROUND Patient support is frequently required during just one part of a procedure (eg the pelvis for the perineal portion of an abdominoperineal resection of the rectum). This is commonly achieved by placing a gel patient positioner underneath the pelvis. However, this positioner can remain in place for a long time and we had noticed that patients complained occasionally of back pain after ...
