The influence of initial pressurization and cup introduction time on the depth of cement penetration in an acetabular model.

Research output: Contribution to journalArticle


Acetabular cementation during total hip
arthroplasty is considered difficult mainly due to the
appearance and anatomy of the acetabulum. Improved
cementation technique has been shown to improve the
longevity of acetabular components.
We designed a ceramic model to investigate
the effect of varying the initial cement pressurization
and cup introduction times on the depth of cement penetration.
4 groups were prepared, 2 of which involved
varying initial cement pressurization and cup introduction
times. Group 3 involved initial cement pressurization
with no cup introduction, while group 4 involved
cup introduction with no prior cement pressurization.
Results and interpretation
Most cement penetration
occurred in the early pressurization phase, and we conclude
that a relatively early and longer cement pressurization
time and late cup introduction are positive factors
for increased cement penetration in the acetabulum
