Stem centralizer
|
A stem centralizer will guide the femoral prosthesis to a neutral position within the cement and guarantee an even cement layer between the bone and prosthesis.
Thickness of the cement mantle around any shaft should be approximately 3 mm to provide sufficient mechanical strength.
Spacers on the acetabular cup will ensure an even cement layer around the cup. The cement mantle should be 2-3 mm, yielding better stress distribution.
The distal cement centralizer is widely used and is assumed to be valuable in affecting the quality of cemented total hip replacement. The literature suggests that the use of the distal centralizer will improve the quality of the distal mantle as well as improve stem position.1,2 This study evaluated stem position, centralization and distal cement mantle in two groups where the distal cement mantle was or was not used.
