[An experimental model of suppurative osteomyelitis]

Area of Science:

• Orthopedics
• Infectious Diseases
• Animal Models

Background:

• Osteomyelitis is a severe bone infection.
• Developing reliable animal models is crucial for research.
• Existing models may have limitations in reproducibility or generalization.

Purpose of the Study:

• To propose a new, reproducible experimental rabbit model for acute purulent osteomyelitis.
• To establish a model that minimizes contamination and generalization of infection.

Main Methods:

• Percutaneous introduction of 4 million Staphylococcus aureus into the femoral medullary canal.
• Aseptic destruction of bone marrow using ethyl alcohol and hot saline.
• Utilizing a rabbit model for osteomyelitis induction.

Main Results:

• The model demonstrated good reproducibility.
• Reduced contamination of periosteal tissues during intraosteal inoculation.
• Successful reproduction of localized inflammation without systemic generalization.
• Decreased number of fatal outcomes among experimental animals.

Conclusions:

• The proposed rabbit model is effective for studying acute purulent osteomyelitis.
• This model offers improved control over infection localization and reduces animal mortality.
• It serves as a valuable tool for future research into osteomyelitis treatments.
