What are the different types of osteomyelitis?

Osteomyelitis has traditionally been classified into three categories.1The first category, hematogenous osteomyelitis , is bone infection that has been seeded through the bloodstream. The second, osteomyelitis due to spread from a contiguous focus of infection without vascular insufficiency, is seen most often after trauma or surgery, and is caused by bacteria which gain access to bone by direct inoculation (for example, a contaminated compound fracture) or extension to bone from adjacent contaminated soft tissue (for example, a prosthetic joint contaminated at the time of implantation). The third category, osteomyelitis due to contiguous infection with vascular insufficiency, is seen almost exclusively in the lower extremities, most commonly as a diabetic foot infection. Each of these three categories of osteomyelitis can present in the acute or chronic phase, in virtually any bone, caused by a variety of bacteria and occasionally fungi. Thus, the approach to osteomyelitis should be guided by several principles, but must be individualized to each unique situation.

What are the symptoms of osteomyelitis?

Patients usually present with signs of acute infection such as fever, chills, pain, and local signs of inflammation.4 In adults, the most common site is the vertebral bodies, followed by long bones, pelvis, and clavicle. The primary blood supply of the vertebrae is the segmental arteries, which divide to perfuse segments of two adjacent vertebrae. Thus, vertebral osteomyelitis often occurs in two contiguous vertebral bodies and the intervertebral disc.5

What antibiotics should I use for acute hematogenous osteomyelitis?

Empiric antibiotics for acute hematogenous osteomyelitis should include an anti-staphylococcal antibiotic such as nafcillin or oxacillin, though vancomycin should be substituted when MRSA is suspected.13,15Additional coverage against gram-negative enteric bacteria, for example a third-generation cephalosporin such as cefotaxime, should be added in newborns, and considered in older children. Empiric gram-negative coverage is also warranted in adults; quinolones are useful in this population.

What is the gold standard for diagnosis of osteomyelitis?

The gold standard for the diagnosis of osteomyelitis is bone biopsy with histopathologic examination and tissue culture. When the patient is clinically stable, one should consider delaying empiric antimicrobial treatment until bone biopsy is performed. An open approach is ideal to ensure that adequate specimen is obtained, particularly when prosthetic material is involved.7Needle biopsy is often used, and the sensitivity and specificity using this modality has been reported as 87% and 93%, respectively.8Specimens should undergo both aerobic and anaerobic bacterial culture. In addition, fungal and mycobacterial cultures should be performed when clinical suspicion of these organisms is present.

Why is osteomyelitis complex?

Because of the heterogeneity of disease severity, anatomic location, organism, and host, treatment of osteomyelitis is complex, and must be individualized. However, several general concepts guide therapy (Table 2).

How does osteomyelitis affect bone?

In experimental models, a large inoculum of bacteria is typically required to induce osteomyelitis.2Bacteria possess a variety of virulence factors that contribute to the development and chronicity of osteomyelitis, such as proteins called adhesins which facilitate attachment to bone3, and the ability to form biofilm, a slime layer which shields the bacteria from antimicrobial agents.4In addition, the host's immune response to infection can damage bone. Several common cytokines have osteolytic properties, and phagocytes produce toxic oxygen radicals and proteolytic enzymes that can harm host cells. The inflammatory response leads to an increase in intraosseous pressure, which impairs blood flow and leads to ischemic necrosis. This dead bone, known as a sequestrum,1can act as a non-living surface for biofilm attachment, allowing bacteria to adopt a lower metabolic rate and to survive in an environment with lower oxygen tension.. Poor blood flow as well as biofilm make it difficult for antimicrobial agents and host immune cells to access the bacteria.4

How long should antibiotics be given for children?

Duration of therapy in children is typically 3 to 6 weeks. The risk of chronic infection increases unacceptably when effective therapy is given for less than 3 weeks.16In adults, parenteral treatment should be given for up to 6 weeks for uncomplicated cases in which no residual nidus of infection is suspected.17

What are the symptoms of osteomyelitis?

A diagnosis of osteomyelitis should be considered in any patient with acute onset or progressive worsening of musculoskeletal pain accompanied by constitutional symptoms such as fever, malaise, lethargy, and irritability. Constitutional symptoms do not always occur in adults, especially in the setting of immunocompromise. The index of suspicion for osteomyelitis should be higher in patients with underlying conditions, including poorly controlled diabetes mellitus, neuropathy, peripheral vascular disease, chronic or ulcerated wounds, history of recent trauma, sickle cell disease, history of implanted orthopedic hardware, or a history or suspicion of intravenous drug use. A dedicated physical examination can increase the likelihood of diagnosing osteomyelitis if findings include erythema, soft tissue infection, bony tenderness, joint effusion, decreased range of motion, or exposed bone. The probe-to-bone test may be useful to rule out diabetic foot osteomyelitis in low-risk patients. 10, 11

How to diagnose osteomyelitis?

Osteomyelitis is usually clinically diagnosed with support from imaging and laboratory findings. Bone biopsy and microbial cultures offer definitive diagnosis. Plain film radiography should be performed as initial imaging, but sensitivity is low in the early stages of disease. Magnetic resonance imaging with and without contrast media has a higher sensitivity for identifying areas of bone necrosis in later stages. Staging based on major and minor risk factors can help stratify patients for surgical treatment. Antibiotics are the primary treatment option and should be tailored based on culture results and individual patient factors. Surgical bony debridement is often needed, and further surgical intervention may be warranted in high-risk patients or those with extensive disease. Diabetes mellitus and cardiovascular disease increase the overall risk of acute and chronic osteomyelitis.

What is the most common pathogen for osteomyelitis?

Methicillin-sensitive Staphylococcus aureus is the most frequently identified pathogen across all types of osteomyelitis, followed by Pseudomonas aeruginosa and methicillin-resistant S. aureus. Hematogenous osteomyelitis is often monomicrobial and can occur from aerobic gram-negative rods or from P. aeruginosa or Serratia marcescens in injection drug users. 4 Vertebral osteomyelitis is the most common type of hematogenous osteomyelitis and is polymicrobial in 5% to 10% of cases. 1 Blood cultures may be negative if osteomyelitis develops following bacterial clearance from the bloodstream. Nonhematogenous osteomyelitis can be polymicrobial; S. aureus is the most common pathogen in addition to coagulase-negative staphylococci and gram-negative aerobes and anaerobes. Polymicrobial diabetic foot infections and decubitus ulcers may include Streptococcus species and Enterococcus species. 1 Less common pathogens can be associated with certain clinical conditions, including immunocompromise ( Aspergillus species, Mycobacterium tuberculosis, Candida species), sickle cell disease ( Salmonella species), HIV infection ( Bartonella henselae ), and tuberculosis ( M. tuberculosis ). 1, 5, 6

What is the differential diagnosis of osteomyelitis?

The differential diagnosis of osteomyelitis includes soft tissue infection, gout, Char-cot arthropathy, fracture, malignancy, bursitis, osteonecrosis, sickle cell vasoocclusive pain crisis, and SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, and osteitis). Uncertain clinical diagnosis should prompt further workup that includes laboratory evaluation and imaging ( Table 1 2, 9, 12, 13). Definitive diagnosis is made with a positive culture from biopsy of the affected bony structure. Polymerase chain reaction testing may help in the rapid diagnosis of organisms or for cultures taken after antibiotic therapy. 12, 14 Bone biopsy remains the diagnostic standard but is not always feasible. Some evidence suggests that biopsy should be reserved only for select cases because the results may not lead to treatment alterations. 15

What is the best diagnostic test for osteomyelitis?

The preferred diagnostic criterion for osteomyelitis is a positive bacterial culture from bone biopsy , but clinical, laboratory, and radiographic findings can also inform a clinical diagnosis. 9, 12

Can diabetic neuropathy cause osteomyelitis?

Patients with diabetic neuropathy are at higher risk of developing osteomyelitis secondary to local spread from diabetic foot infections and unrecognized wounds. 2 Smoking increases the risk of osteomyelitis from diabetic foot infections and healing fractures. 7 Peripheral vascular disease and poorly healing wounds (e.g., decubitus ulcers) are more likely to lead to bone inflammation. Osteomyelitis secondary to diabetic foot ulcers can be difficult to diagnose given chronic changes from vascular insufficiency and ischemia. 8

Can osteomyelitis be diagnosed with MRI?

MRI is more readily available and avoids radiation exposure, but positron emission tomography (PET) and single-photon emission computed tomography (SPECT) can also reliably diagnose osteomyelitis. 25 In patients in whom MRI is contraindicated, a tagged leukocyte scan, computed tomography (CT), PET/CT, or sulfur colloid marrow scan can be appropriate; however, diagnosis may be impeded because of false-positive results from recent surgery or trauma, healed osteomyelitis, arthritis, bony tumors, Paget disease of bone, or reduced uptake secondary to necrosis and poor blood flow. 13, 29, 30 Ultrasonography plays a complementary role to other modalities and may demonstrate inflammatory changes in the periosteum, particularly in children. Ultrasonography can be useful for identification of soft tissue abscess and helpful for abscess aspiration. 13

How is osteomyelitis managed?

Osteomyelitis is best managed by a multidisciplinary team. It requires accurate diagnosis and optimization of host defenses, appropriate anti-infective therapy, and often bone débridement and reconstructive surgery.

What tests are done to check for osteomyelitis in children?

The provider treating your child will first do a thorough history and physical exam that may indicate signs of osteomyelitis like those listed above. An additional workup generally includes blood tests that look at white blood cells as well as markers for inflammation that are usually elevated during an infection.

What is the term for swelling of bone tissue?

Osteomyelitis is an inflammation or swelling of bone tissue that is usually the result of an infection. Bone infection may occur for many different reasons and can affect children or adults. Osteomyelitis may occur as a result of a bacterial bloodstream infection, sometimes called bacteremia, or sepsis, that spreads to the bone.

What is the term for inflammation of the bone?

Osteomyelitis is inflammation or swelling that occurs in the bone. It can result from an infection somewhere else in the body that has spread to the bone, or it can start in the bone — often as a result of an injury. Osteomyelitis is more common in younger children (five and under) but can happen at any age. Boys are usually more affected ...

How do you know if you have osteomyelitis?

The following are the most common symptoms of osteomyelitis; however, each individual may experience symptoms differently: Fever (may be high when osteomyelitis occurs as the result of a blood infection) Pain and tenderness in the affected area. Irritability in infants who can’t express pain. Feeling ill.

Can osteomyelitis be a medical condition?

The symptoms of osteomyelitis may resemble other medical conditions or problems. Always consult your doctor for a diagnosis.

How to treat osteomyelitis in the spine?

Instead, patients with spinal osteomyelitis are given intravenous antibiotics. After surgery, antibiotics against the specific bacteria involved in the infection are then intensively administered during the hospital stay and for many weeks afterward.

Why is it important to treat osteomyelitis?

The objective of treating osteomyelitis is to eliminate the infection and prevent the development of chronic infection. Chronic osteomyelitis can lead to permanent deformity, possible fracture, and chronic problems, so it is important to treat the disease as soon as possible.

What is osteomyelitis infection?
