-AbstractStudy Design : A case report and review of the literature.Objective : To discuss the intraspinal gas associated with lumberjack injury and review the literature. Material and Method :A 60-year-old man developed chest pain & paraplegia by fall down from 4m height, having hypoesthesia on T7-8 dermatome and complete motor-sensory loss below T9.Results : Multiple rib fractures and hemopneumothorax were observed on chest radiograph and only mild offset was noted on plain spine lateral radiograph. CT scan reveals multiple air bubbles around epidural space at T7-8 and fracture of T7 pedicle.MRI shows rupture of both anterior and posterior longitudinal ligaments and extruded intervertebral disc of T7-8. Posterior decompression and stabilization with posterolateral fusion was performed on T5-9, but pain was persisted and paralysis was not improved after surgery.Summary : The intraspinal gas of this case is supposed to be made by air migration from pleural cavity to intraspinal canal because of severe soft tissue injuries and fistula formation. Immediate and precise diagnosis with operative treatment was considered to be important.
