title: Pyogenic vertebral osteomyelitis: treatment by anterior spinal debridement and fusion.
abstract: Forty-three patients with pathologically proven vertebral osteomyelitis were studied between 1957 and 1990. Thirty-nine underwent anterior debridement and fusion, and four underwent anterior debridement only. The indications for surgery were uncertain diagnosis, persistent pain, failed conservative treatment with uncontrolled sepsis, and neurological involvement. Thirty patients were followed-up for an average period of 5 years, with a minimum of 2 years and the longest for 15 years. All their symptoms improved after surgery; only one patient subsequently deteriorated due to multiple level recurrence. All patients with neurological deficit improved. Bony fusion occurred in 93% of cases (average time to fusion, 6.8 months), and 90% of the patients were able to return to their original work 4-20 months after surgery. We feel that anterior debridement and spinal fusion allow for reliable microbiological and histological diagnosis, and rapid relief of symptoms and return to work. Primary bone grafting is successful despite the presence of infection.
