概要

TLDROsteomyelitis is an infection of the bone primarily caused by bacteria. It can occur when microorganisms enter the bone through open wounds or via the bloodstream. Symptoms include pain, abscess formation, and loss of bone function. Diagnosis relies on imaging techniques like MRIs and lab tests to check for elevated infection indicators. Treatment typically requires surgical removal of infected tissue and intravenous antibiotics administered for several weeks. Initial antibiotic treatment may be empirical pending lab results.

タイムライン

    Osteomyelitis is a bone infection caused primarily by bacteria. It can be introduced into the bone through open wounds or hematogenous spread via the bloodstream. Open wounds, often from injuries or sores, expose the bone to microorganisms found in dirt, water, or air. Indications of this condition include pain, loss of function, abscess formation, and dead bone. Diagnosis might not be apparent on X-rays initially but can be detected using MRIs or bone scans. Blood work, including increased white blood cell count and inflammatory markers, helps confirm suspicion of infection. Treatment often involves surgical removal of infected tissue and antibiotics, guided by lab culture results to determine the most effective treatment.

ビデオQ&A

  • What is osteomyelitis?

    Osteomyelitis is a bone infection caused by microorganisms, typically bacteria.

  • How do microorganisms enter the bone?

    Microorganisms can enter the bone through open wounds or by traveling through the bloodstream.

  • What are the symptoms of osteomyelitis?

    Symptoms may include pain, loss of function, abscess formation, and dead bone.

  • How is osteomyelitis diagnosed?

    Diagnosis often involves X-rays, MRIs, bone scans, and blood work.

  • What does treatment for osteomyelitis involve?

    Treatment often includes surgery to remove infected tissue and antibiotics, typically administered through IV.

  • Why might antibiotics be given empirically?

    Antibiotics may be given empirically while waiting for culture results based on previous similar infections.

  • How long are IV antibiotics usually needed?

    IV antibiotics are commonly needed for several weeks after the infection is diagnosed.

  • What lab results may indicate an infection?

    High white blood cell count, elevated sedimentation rate, and high C-reactive protein (CRP) levels may indicate infection.

  • 00:00:11
    osteomyelitis can be thought of Simply
  • 00:00:13
    as a bone
  • 00:00:15
    infection osteomyelitis occurs when
  • 00:00:19
    microorganisms usually bacteria are able
  • 00:00:22
    to grow in bone and bone
  • 00:00:25
    marrow there are two ways that the
  • 00:00:27
    microorganisms can be introduced into
  • 00:00:29
    the bone
  • 00:00:31
    the first way is through an open wound
  • 00:00:34
    the open wound may occur with an injury
  • 00:00:36
    such as an open fracture there are
  • 00:00:39
    bacteria everywhere if bone is exposed
  • 00:00:42
    to dirt water or even air microorganisms
  • 00:00:45
    May Seed to the Bone begin to grow and
  • 00:00:48
    cause an
  • 00:00:50
    infection bone may also be exposed to
  • 00:00:52
    microorganisms in open sores and
  • 00:00:55
    overlying soft tissue infections people
  • 00:00:58
    with diabetes often have sores on their
  • 00:01:00
    feet that can become infected Orthopedic
  • 00:01:03
    implants such as plates screws and knee
  • 00:01:06
    replacement prosthesis make good places
  • 00:01:09
    for bacteria to
  • 00:01:11
    grow the second way that osteomyelitis
  • 00:01:14
    occurs is when microorganisms travel
  • 00:01:17
    through the blood until they are able to
  • 00:01:19
    settle in the bone this is known as
  • 00:01:21
    hematogenous infection often this occurs
  • 00:01:25
    because bacteria from another infection
  • 00:01:27
    in the body travel through the
  • 00:01:28
    bloodstream to the Bone bone whatever
  • 00:01:31
    the cause and whatever the source the
  • 00:01:34
    infection can begin to eat away at the
  • 00:01:36
    bone this can result in pain loss of
  • 00:01:39
    function a collection of pus known as an
  • 00:01:41
    abscess and dead
  • 00:01:43
    bone osteomyelitis is not usually
  • 00:01:46
    visible on x-rays for several days after
  • 00:01:49
    it begins it will show up earlier on
  • 00:01:51
    MRIs or bone
  • 00:01:53
    scans blood work is also important the
  • 00:01:57
    white blood cell count is usually High
  • 00:01:59
    lab values known as the arthrite
  • 00:02:02
    sedimentation rate or said rate and the
  • 00:02:05
    CRP C reactive protein are usually
  • 00:02:08
    obtained when osteomylitis is suspected
  • 00:02:11
    if they are high it raises the doctor's
  • 00:02:14
    suspicion of infection these lab values
  • 00:02:17
    are monitored as the infection is
  • 00:02:19
    treated if they drop it is an indication
  • 00:02:21
    that the treatment is
  • 00:02:24
    working treatment depends on what bone
  • 00:02:27
    is involved where the infection is
  • 00:02:29
    located
  • 00:02:30
    whether an abscess or dead bone is
  • 00:02:32
    present the age of the patient and other
  • 00:02:36
    factors treatment often involves surgery
  • 00:02:39
    to remove infected bone and soft tissue
  • 00:02:42
    the affected area is Thoroughly
  • 00:02:44
    irrigated to wash away the bacteria and
  • 00:02:47
    pus the infected bone is then sent to
  • 00:02:49
    the lab for
  • 00:02:51
    analysis within a few days the bacteria
  • 00:02:54
    can be grown in a culture in the lab and
  • 00:02:56
    tested with different antibiotics to see
  • 00:02:58
    which antibiotics are most effective at
  • 00:03:01
    killing it while the doctors wait for
  • 00:03:03
    these culture and sensitivity results
  • 00:03:06
    they can only make an educated guess as
  • 00:03:08
    to which antibiotics will be best this
  • 00:03:11
    is known as empirical
  • 00:03:13
    treatment they make this guess based on
  • 00:03:16
    what types of organisms have caused
  • 00:03:18
    similar infections in similar
  • 00:03:20
    patients these antibiotics are usually
  • 00:03:23
    given through an
  • 00:03:24
    IV IV antibiotics are often necessary
  • 00:03:27
    for several weeks after the infection is
  • 00:03:30
    discovered
