Cement Viscosity and Application Time Lead to Significant Changes in Cement Penetration and Contact Surface Area.

ABSTRACT:

Background

Application time and viscosity are factors that can significantly affect the properties of bone cement and implant fixation. The aim of this study was to investigate the influence of different application times of 2 different cements on mechanical parameters, cement interdigitation, and cement distribution.

Methods

P.F.C. Sigma tibial trays were cemented with high-viscous Palacos R and medium- to low-viscous Simplex P in an open-cell model. The application was performed at different times within the manufacturer's specifications. Cement interdigitation and micromotion were measured with computed tomography scan using a novel method.

Results

Significant differences of insertion forces were found at all times of cement application. Cement penetration decrease
