Introduction

Calcium sulphate is a resorbable void filler that can be used for local antibiotic delivery.

Results from clinical studies on chronic osteomyelitis thus treated with local vancomycin have already been published. Despite significant exposure to this drug, there are no pharmacokinetic studies published so far. Based on observations in our patients, a model predicting vancomycin serum and wound fluid levels and toxicity potential is presented.

Methods

Following implantation of Osteoset® added with vancomycin, serum and wound fluid concentrations of this antibiotic have been monitored systematically. The pharmacokinetic analysis was performed using a non-linear mixed-effects model based on a one-compartment model with first-degree absorption.
