Abstract
|
|
|
|
Herein we report three cases of dorsal epidural migration of sequestered lumbar disc fragment in male patients older than 60 years. One of the patients underwent a microscopic decompression and discectomy for a herniated lumbar intervertebral disc disease five months ago. The magnetic resonance imaging showed characteristic features of dorsal epidural migration of a sequestered lumbar disc fragment. We suggest that both, older age and previous intervertebral decompression surgery may be the predisposing factors for the dorsal epidural migration of the sequestered lumbar disc fragment.
