Study Notes
Osteomyelitis: Diagnosis and Microbiology
- Acute hematogenous osteomyelitis is typical in males during childhood and adolescence
- The pyogenic organism reaches the bone through the bloodstream from a known focus of infection
- Diagnosis involves clinical presentation, laboratory tests, biopsy, and imaging
- In acute hematogenous osteomyelitis, inflammation indices are often elevated
- At least three tissue samples are required for biopsy and culture
- Microbiology varies based on age, type of osteomyelitis, and location
- Imaging includes radiography, computed tomography, magnetic resonance imaging, and nuclear medicine
- Treatment of acute osteomyelitis is predominantly based on antibiotic therapy
Osteomyelitis: Chronic Forms and Treatment Strategies
- Chronic forms of osteomyelitis may require surgical intervention
- Extensive bone involvement may necessitate complete removal and reconstructive techniques
- Treatment involves sequestrectomy, debridement, and appropriate antibiotics
Prosthetic Joint Infections: Burden and Risk Factors
- Prosthetic joint infection is a serious complication of prosthetic joint implantation
- ~2% of total procedures (~150,000/year in Italy) are affected
- Cultures are negative in up to 15% of cases
- Risk factors include surgical factors and patient characteristics
Prosthetic Joint Infections: Diagnosis and Treatment
- Management consists of surgery and antimicrobial therapy
- Surgical options include debridement and retention of prosthesis, resection arthroplasty with reimplantation, resection arthroplasty with no reimplantation, or amputation
