Pyogenic non-tuberculous spinal infection: an analysis of thirty cases.

Thirty patients with non-tuberculous pyogenic osteomyelitis of the spine are reported in all of whom the diagnosis was confirmed bacteriologically, histologically or serologically. The clinical and radiological features and investigations are analysed. Back pain, localised to the level involved, was the predominant symptom. The erythrocyte sedimentation rate was raised in all cases, and a characteristic sequence of radiological features is described.
