Background

Medical grade Calcium Sulphate can be used as a delivery vehicle for antibiotics. We use these for treating patients with established osteomyelitis, but also use it prophylactic for contaminated war injuries, to fill voids in bone with osteo conductve filler that delivers local antibiotics, and can integrate with bone. Although antibiotic loaded calcium sulphate is increasingly used, there is little data to demonstrate that systemic levels generated by local release of antibiotics are safe. For this reason, we routinely assay systemic levels of antibiotics.
