Abstract:
Five patients with vertebral fracture and spinal epidural hematoma (SEH) are described. Another 58-year-old man developed a post-traumatic SEH without bony damage. From the literature, 38 patients (31 male, 4 female, and 3 unknown) were collected. Ankylosing spondylitis or rheumatoid arthritis was noted in 9 of 12 subjects between 50 and 75 years of age. Two groups of patients were identified: Group 1--16 patients with spinal fracture (aged 23 to 63 years), and Group 2--22 patients without spinal fracture (the age was less than 18 years in 12 subjects). In Group 2, a coagulation defect or spinal epidural vascular malformation resulted in a SEH in 6 patients. The preoperative myelopathy was complete in 3 patients each from Group 1 (23.1%) and Group 2 (16.7%). Of the 31 patients operated upon, 9 of the 13 from Group 1 (69.3%) and 6 of the 18 from Group 2 (33.3%) underwent laminectomy within 1 week after the onset of symptoms. Postoperative neurological return was observed in 38.5% (5 of 13) and 88.9% (16 of 18) of these two groups of patients, respectively. Post-traumatic SEHs, predominant in the male population, are often associated with vertebral disease in elderly patients. In the very young patient, there is usually no fracture/dislocation of the spine. A predisposing lesion may be present when spinal fracture is not evident. The prognosis after surgical intervention is better in patients without spinal fracture than in those with vertebral damage, probably because of less contusion to the spinal cord and the presence of very young subjects in the former group of patients.
