Hello and welcome to the zero to finals podcast. My name is Tom and in this episode

I'm going to be talking to you about osteomyelitis. And you can find written notes on this topic

at zero to finals.com slash orthopedics or in the orthopedic section of the

zero definals surgery book so let's get straight into it osteomyelitis refers to inflammation of the bone

and the bone marrow usually caused by bacterial infection.

Hematogenous osteomyelitis refers to when a pathogen is carried through the blood and seeded

in the bone. This is the most common mode of infection. Alternatively, osteomyelitis can occur

due to direct contamination of the bone, for example

at a fracture site or during an orthopedic operation. Staphylococcus aureus is the bacteria that most

often causes osteomyelitis. Osceomyelitis can be acute or chronic.

Patients may develop recurring or chronic infections after treatment for acute osteomyelitis.

Let's talk about the risk factors.

The key risk factors for developing osteomyelitis are open bone fractures,

orthopedic operations, particularly with prosthetic joints,

diabetes, particularly with diabetic foot ulcers,

peripheral arterial disease which will affect the blood supply to the area,

intravenous drug use and

immunosuppression. Infection in a prosthetic joint is a big problem. This occurs in around 1% of

joint replacements and extensive measures are taken to prevent it, such as perioperative prophylactic antibiotics.

Prostatic joint infections are more likely to occur in revision surgery compared with an initial

joint replacement.

Let's talk about the presentation.
