title: Spondylodiscitis.
abstract: Spondylodiscitis is an infection of the spine that has been known since ancient times. Its incidence is rising, due to the increases in life expectancy and debilitating conditions. Its age distribution is bimodal, affecting persons younger than 20 years of age or persons aged 50-70 years. According to its origin, it is classified as pyogenic, granulomatous or parasitic, though the first form is the most common, usually caused by Staphylococcus aureus or Escherichia coli. The clinical presentation is insidious, resulting in a delayed diagnosis, particularly in tuberculous spondylodiscitis. The initial onset usually involves inflammatory back pain, though the disease may course with fever, asthenia and neurological deficit, these being the most severe complications. Diagnosis is based on clinical, radiological, laboratory, microbiological and histopathological data. Magnetic resonance imaging is the technique of choice for the diagnosis of spondylodiscitis. The differential diagnosis involves, among other conditions, intervertebral erosive osteochondrosis, tumour, axial spondyloarthropathy, haemodialysis spondyloarthropathy, Modic type 1 endplate changes and Charcot's axial neuroarthropathy. Treatment is based on eliminating the infection with antibiotics, preventing spinal instability with vertebral fixation, and ample debridement of infected tissue to obtain samples for analysis.
