What are the two types of osteomyelitis?

Traditionally, osteomyelitis is a bone infection that has been classified into three categories: (1) a bone infection that has spread through the blood stream (Hematogenous osteomyelitis) (2) osteomyelitis caused by bacteria that gain access to bone directly from an adjacent focus of infection (seen with trauma or

What are the long term effects of osteomyelitis?

Osteomyelitis needs long-term care to prevent complications, such as: Fractures of the affected bone. Stunted growth in children, if the infection has involved the growth plate. Tissue death (gangrene) in the affected area.

What are the complications of osteomyelitis?

Some of the complications of osteomyelitis include:

  • Bone abscess (pocket of pus)
  • Bone necrosis (bone death)
  • Spread of infection.
  • Inflammation of soft tissue (cellulitis)
  • Blood poisoning (septicaemia)
  • Chronic infection that doesn’t respond well to treatment.

Can you have osteomyelitis for years?

With treatment, the outcome for acute osteomyelitis is often good. The outlook is worse for those with long-term (chronic) osteomyelitis. Symptoms may come and go for years, even with surgery. Amputation may be needed, especially in people with diabetes or poor blood circulation.

What is the treatment for chronic osteomyelitis?

Chronic osteomyelitis is generally treated with antibiotics and surgical debridement but can persist intermittently for years with frequent therapeutic failure or relapse. Despite advances in both antibiotic and surgical treatment, the long‐term recurrence rate remains around 20%.

How long do you treat osteomyelitis?

You’ll usually take antibiotics for 4 to 6 weeks. If you have a severe infection, the course may last up to 12 weeks. It’s important to finish a course of antibiotics even if you start to feel better. If the infection is treated quickly (within 3 to 5 days of it starting), it often clears up completely.
