Osteomyelitis is the inflammation of the bone due to infection by bacteria.


Bacteria could be introduced during orthopedic surgery or contamination from wounds or preexisting infection in lung or other tissues, such as pneumonia or abscesses.

Acute presenting signs

Fever, systemic illness.

In very young animal it’s due by omphalophlebitis.

Chronic presenting signs

Limb dysfunction, muscle wasting, local pain, draining fistulous tracts.

Age predisposition

In young dog, acute osteomyelitis is primary disease following hematogenous spread.

Confirmation of diagnosis

Diagnosis is based on clinical signs and radiographic evidence such as bone lysis and periosteal reaction.

It’s important remember that in initial phase of osteomyelitis, there are few changes of bone and periosteal tissue.

Standard treatment

High dose systemic broad spectrum antimicrobials if it’s possible based on results of antibiogram.

In cronic case, it’s required surgery to remove necrotic area and antimicrobials therapy.
