Analysis of Cement Mantle in Relation to Surgical Approach
ثبت نشده
چکیده
Aseptic loosening remains the commonest cause of failure of total hip arthroplasty. Cement mantle defects are associated with aseptic loosening. Cementing technique has a profound influence on the incidence of aseptic loosening of total hip replacements. Two specific measures that seem to have the greatest impact on the longevity of cemented femoral stems are pressurization of cement and control of mantle thickness. Although there have been considerable improvements in cementing techniques cement mantle defects are still present, in particular in Gruen Zones I, VII and XII.

The posterior approach reduces the risk of thin cement mantles with a straight femoral stem design
BACKGROUND AND PURPOSE The properties of the cement mantle around a prosthesis are important. We investigated whether the surgical approach to the hip influences the quality and thickness of the cement mantle when using a straight femoral stem design. METHODS In a consecutive multi-surgeon series, we reviewed the radiographs of 270 patients after cemented Exeter total hip arthroplasty. 135 st...
متن کاملEffects of a less-invasive surgical technique on cement mantle quality in total knee arthroplasty.
The purpose of this study was to assess the effects of a less-invasive midvastus exposure during total knee arthroplasty (TKA) on cement mantle grade compared with a standard parapatellar arthrotomy and standard TKA. Fifty consecutive cemented minimally invasive TKAs using a midvastus approach, patellar subluxation without eversion, and less-invasive instrumentation were compared radiographical...
متن کاملThickness effects on maximum von-Mises stress of a cement mantle in total hip replacement - a finite element study.
AIM The present study seeks to increase the life term of fully cemented total hip replacements by minimizing the stress values within the cement mantle. METHODS Three-dimensional (3D) finite element analyses have been carried out to investigate the effects of varying cement thickness on the von-Mises stress of a cement mantle. The magnitude and location of maximum von-Mises stress within the ...
متن کاملUncompromised quality of the cement mantle in Exeter femoral components implanted through a minimally-invasive direct anterior approach. A prospective, randomised cadaver study.
A complete cement mantle is important for the longevity of a total hip replacement. In the minimally-invasive direct anterior approach used at the Innsbruck University hospital, the femoral component has to be inserted into the femoral canal by an angulated movement. In a cadaver study, the quality and the extent of the cement mantle surrounding 13 Exeter femoral components implanted straight t...
متن کاملFinite element study regarding the influence of the cement mantle thickness on the stress distribution in a cemented hip joint
The disrupted function of the hip joint can be restored by means of total hip arthroplasty (i.e. reconstructive surgery of the joint) THA. This is a widely used medical strategy with high succes rates, world wide [1,2]. Among the failure scenarios of THA, aseptic loosening represents the main reason for revision of cemented hip implants [3]. Studies have shown that the two most frequent ways fo...
