USE OF A NEW ANTIBIOTIC BONE SUBSTITUTE TO INDUCE HEALING OF OSTEOMYELITIS IN THE DIABETIC FOOT

Aim of this work was to evaluate the efficacy of a new antibiotic bone substitute (CERAMENTTM|G) in the treatment of osteomyelitis (OM) in diabetic foot.From June 2013 to April 2015 we used a new Calcium Sulphate Hemihydrate + Hydroxyapatite + Gentamicin Sulfate (CSH + HA + GS) compound to fill resected bone voids following surgical intervention in cases of diabetic foot OM. The uniqueness of this product is that it induces native bone growth, while the synthetic bone disappears and antibiotic is released into the surrounding tissues, maintaining high gentamicin concentrations for some weeks.In 20 patients, with or without Charcot neuroarthropathy and post-lesional osteomyelitis, after removal of infected bone we applied 10 to 20 ml CSH + HA + GS, filling the residual spaces and aiming to stabilize the remaining bone fragments. When needed, these arthrodeses were stabilized by external-internal hybrid fixators. X-ray evaluations and, when indicated, MRI evaluations were performed before and after surgical...
