Presentation reference

Is it this?

Reference only, to read alongside your own examination.

Symptoms — what the patient reports (5)

  • Local redness, swelling, and warmth develop at the infection site, sometimes with a dull pain that worsens with movement [redness]
  • Fever or chills can accompany the local symptoms [chills · fever]
  • The chronic form runs a longer course, usually over two weeks, with less prominent fever than the acute form [fever]
  • New or worsening back or neck pain with fever should raise concern for spinal osteomyelitis, especially with raised inflammatory markers or known bacteremia [back pain · fever · neck pain]
  • A chronic wound, especially in someone with diabetes, that fails to heal after weeks of proper care should raise concern for underlying bone infection

Signs — what you find (2)

  • Tenderness over the vertebral bone on palpation can be a key finding in spinal osteomyelitis
  • Being able to probe an ulcer down to bone with a blunt instrument strongly suggests underlying osteomyelitis

Tests (7)

  • White cell count, ESR, and CRP may be raised but are not specific; CRP level tracks response to treatment
  • Blood cultures can be positive, particularly in blood-borne infection of the vertebrae, collarbone, or pubic bone
  • Plain x-rays can lag about 14 days behind the onset of infection and may miss early disease, though they help rule out other causes
  • A lytic lesion only becomes visible on x-ray once roughly 50 to 75 percent of the bone matrix is destroyed
  • MRI is the most sensitive and specific imaging test and can detect infection within 3 to 5 days of onset
  • A negative MRI after at least a week of symptoms is enough to rule the diagnosis out
  • Bone biopsy establishes the histologic diagnosis and identifies the organism to guide antibiotics; superficial wound swabs do not substitute for it

If not this — what else fits (8)

  • Charcot arthropathy, particularly in diabetes, is on the differential
  • SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis) is on the differential
  • Rheumatoid and other forms of arthritis are on the differential
  • Metastatic bone disease is on the differential
  • A pathological or stress fracture is on the differential
  • Gout is on the differential
  • Avascular necrosis of the bone is on the differential
  • A sickle cell vaso-occlusive pain crisis is on the differential, since it can mimic bone infection

EMERGENCY HOSPITAL ADMISSION AND PARENTERAL ANTIBIOTIC THERAPY (SURGICAL & ID REFERRAL)

1st line
Adult dose and duration

Arrange immediate emergency hospital admission to orthopaedics or infectious diseases. Get blood cultures and imaging FIRST. In a haemodynamically stable patient with a normal neurological examination, hold antibiotics until there is a microbiological diagnosis - IDSA recommendation 24. Treat blind only if the patient is unstable: sepsis, or a progressing neurological deficit. Surgical debridement or drainage as indicated - Immediate emergency referral; 6 weeks of parenteral or highly bioavailable oral therapy for most patients, 3 months for Brucella

Paediatric dose

Immediate emergency admission to pediatric orthopedics for parenteral antibiotic therapy and surgical drainage of subperiosteal abscess if present.

Dose source

2015 IDSA Clinical Practice Guidelines for the Diagnosis and Treatment of Native Vertebral Osteomyelitis in Adults

Why

Acute osteomyelitis is a surgical and medical emergency requiring urgent hospital admission, bone biopsy/cultures, parenteral high-dose antibiotics, and potential surgical debridement.

Cautions
  • Do not start antibiotics before cultures in a stable patient. A blind start sterilises the cultures and leaves months of treatment aimed at a guess. The exception is the unstable patient, where the delay costs more than the culture.
  • TIME-CRITICAL EMERGENCY: Primary care physicians must refer immediately for inpatient management; delay risks chronic osteomyelitis, permanent limb disability, pathological fracture, and sepsis.
  • Do not attempt outpatient oral antibiotic monotherapy without hospital evaluation and microbiological diagnosis.
  • In diabetic foot osteomyelitis or open fractures, empiric regimen must cover polymicrobial Gram-negative and anaerobic pathogens.
  • The guideline this is drawn from covers native vertebral osteomyelitis in adults. Long-bone disease, prosthetic joints and children are outside its scope.
  • What the hospital will start once cultures are taken, for the call ahead: ceftriaxone 2 g IV daily plus vancomycin 15-20 mg/kg IV every 12 hours, or cefazolin or flucloxacillin where the organism allows.

Why

First-line broad-spectrum parenteral cephalosporin for Gram-negative and streptococcal osteomyelitis, combined with anti-staphylococcal therapy.

Cautions
  • Contraindicated in severe anaphylactic allergy to cephalosporins or penicillins.
  • Do not co-administer with IV calcium-containing solutions due to risk of precipitation.
  • 2 g every 12 hours is the meningitis and CNS dose, not the bone one. The formulary reserves it for that.
