摘要
Spontaneous spinal infections, such as pyogenic spondylodiscitis(PSD)and spinal epidural abscess(SEA), are relatively rare, but the number of patients is increasing because of the increase in the older population with chronic comorbidities. Magnetic resonance imaging is the most useful tool for identifying PSD or SEA, with high sensitivity and specificity. Effective antibiotic medication is essential to treat the infection, and selection of antibiotics should be based on not only sensitivity to the causative bacteria, but also ability to penetrate bone tissues. Medication should be continued for at least 6 weeks while monitoring C-reactive protein levels. Surgical treatment is indicated when neurological symptoms or severe spinal instability cannot be managed conservatively. Percutaneous endoscopic surgery enables simultaneous tissue sampling for diagnosis and curative debridement without injury to the spinal supporting tissues. Anterior debridement and interbody fusion(ADIF)with autologous bone grafts have been frequently used for PSD. ADIF can be applied more easily to the lumbar spine using techniques and devices for lateral interbody fusion. Posterior decompression is frequently performed in patients with SEA without severe spinal instability. Percutaneous posterior instrumentation, with or without posterior decompression, is a useful option for PSD, especially in the thoracic spine.
