Treatment of chronic osteomyelitis with antibiotic-loaded bone void filler systems: an experience with hydroxyapatites calcium-sulfate biomaterials

none3noThis is a retrospective study that aims to quantify the problem of chronic osteomyelitis in one of the largest Italian orthopedic centers. Furthermore this study is focused on evaluation of efficacy of bone void filler systems with particular attention to a subgroup of patients treated with PerOssal®. Ninety-seven patients were included in this study between 2008 and 2013 with a minimum follow up of 24 months. A subgroup of 52 patients was treated with curettage plus PerOssal®, another group was treated with curettage only or curettage with other bone void filler systems. Overall we obtained a cure rate of 80,4%, whereas 19,6% had recurrent infection. Looking at the subgroup treated with PerOssal® we found a healing rate of 86,5%, which was significantly higher compared to the other groups. Of the patients with recurrence of infection, those treated with PerOssal® recurred 106 days later than the other patients.mixedVisani J; Staals EL; Donati D;Visani J; Staals EL; Donati D
