STIMULAN is a void filler and the characteristics of STIMULAN make it suitable as a carrier material for substances such as antibiotics. STIMULAN is absorbed over 30-60 days and is therefore not suitable for load bearing. An antibiotic loaded spacer is a device placed into the joint to maintain normal joint space and alignment. Spacers are made with bone cement and loaded with antibiotics. The cement does not get absorbed by the body and therefore needs to be removed during revision surgery.
