A Retrospective Study of Dogs with Osteomyelitis Secondary to Fractures (2016-2020)

The purpose of this work was to evaluate the role of surgical procedures and the effectiveness of antimicrobial therapy in dogs with osteomyelitis secondary to fractures repair. Medical records between 2016 and 2020 were analyzed. Clinical data including signalment, affected bone segment, fracture type, isolated microorganisms, antimicrobial susceptibility profiles, applied therapeutic management and fracture healing time were documented. Eleven cases were confirmed with exogenous osteomyelitis of long bones secondary to fractures repair. The most common microorganisms isolated were Staphylococcus spp., Streptoccocus spp., and Escherichia coli. Amoxicillin and clavulanate potassium followed by ceftriaxone were the most effective drugs. High-resistance rates were documented for penicillin and clindamycin. All 10 cases undergoing surgical revision were cured in 10-17 weeks. Simultaneous debridement with implant removal, reduction, and rigid internal fracture fixation is a satisfactory method for revision surgery in treatment of long bones fractures complicated with osteomyelitis.
