[An experimental model of suppurative osteomyelitis]
Abstract:
A new experimental rabbit model of acute purulent osteomyelitis is proposed. The model is reproduced by percutaneous introduction of 4 million St. aureus microorganisms into the medullary channel of the femoral bone after aseptic destruction of the bone marrow by ethyl alcohol and hot saline. The model satisfies the demands of good reproduction, reduces probability of contamination of periosteal tissues during intraosteal inoculation and provides reproduction of local inflammation without its generalization which results in reduced number of fatal outcomes among experimental animals.
Insights
A novel rabbit model for acute purulent osteomyelitis was developed using Staphylococcus aureus. This reproducible model allows for localized inflammation without generalization, reducing animal mortality.
