A multicenter study of localized antibiotic released hydroxyapatite beads for bone infection treatment in Thailand

Phase 3
Completed
Conditions
The ability of new antibiotics impregnated hydroxyapatite beads in treatment of chronic osteomyelitis will be evaluated together with the bone fusion properties.

Lead Sponsor
Health System Research Institute
Brief Summary

Satisfactory outcomes were observed in term of success rate, quality of life and adverse effect. Systemic exposure to vancomycin and gentamicin after beads implantation was limited and high local antibiotics concentrations were found in wound drainage fluid at 24, 48 and 72 h. Blood chemistry measurements did not show any nephrotoxic or hepatotoxic effects.
