Abstract:
Intraosseous gas formation may occasionally be seen within vertebral crush fractures after spinal osteoporosis. This is due to a vacuum phenomenon which follows impaired fracture healing and may be related to avascular necrosis. Four cases are reported from rural Thailand. A high incidence may reflect inappropriate steroid therapy.
