The lumbar extradural structure changes with increasing age.
We have examined the extradural space using a flexible extraduroscope in 74 patients undergoing extradural anaesthesia at the L2-3 interspace. Extraduroscopy showed that the extradural space becomes widely patent and the fatty tissue in the extradural space diminishes with increasing age. We postulate that these age-related structural changes may affect the spread of local anaesthetic in the ex...
متن کاملPositive lumbar extradural space pressure.
Specially selected soft Macintosh balloon indicators were attached to needles during five extradural and five spinal punctures. When the needle point entered the extradural space, the mean balloon pressure decreased suddenly from 24.9 (range 14-37) to 12.3 (10-16) mm Hg in the five extradural punctures and from 22.3 (17-28) to 13.7 (10-17) mm Hg in the five spinal punctures. In the five spinal ...
متن کاملLumbar intraspinal extradural ganglion cyst.
A case is presented of an intraspinal extradural ganglion cyst at the L4-5 level. The clinical picture suggested a herniated nucleus pulposus at this level. A myelogram revealed a round lesion almost completely obstructing the flow of Pantopaque at the L4-5 level. A ganglion cyst with a haemorrhage into it and the surrounding tissue was removed, and surgery was followed by complete recovery.
متن کاملQualitative changes with age of proteoglycans of human lumbar discs.
A detailed study of the biochemistry of each of the lower lumbar intervertebral discs from 3 spines aged 8, 16, and 44 years has shown progressive changes down the spine in a number of biochemical parameters. These were most apparent in the 44-year-old spine. The chemical composition of proteoglycans of the nucleus pulposus and of its constituent proteoglycans differed from those of the corresp...
متن کاملWhite Matter Changes and Word Finding Failures with Increasing Age
BACKGROUND Increasing life expectancy necessitates the better understanding of the neurophysiological underpinnings of age-related cognitive changes. The majority of research examining structural-cognitive relationships in aging focuses on the role of age-related changes to grey matter integrity. In the current study, we examined the relationship between age-related changes in white matter and ...
