Measuring Dimensions of Lumbar Intervertebral Discs in Normal Subjects
Introduction: Disc degeneration is a natural aging process characterized by changes in appearance and chemical structure of the disc. This degeneration leads to back pain. In regard to the limitation of current therapeutical methods for patients with degenerated discs, arthroplasty has been suggested as an alternative method. To manufacture artificial discs for Iranians, determining normal lumb...
متن کاملAn Operative Series of Lumbar Intervertebral Discs
THIS is a review of one hundred cases taken from approximately five hundred cases operated upon in Musgrave Park Hospital during the past twelve years. These cases have been selected because of positive findings of disc prolapse demonstrated at operation. The time from operation varies from twelve years to one year, the average length of follow-up being seven years and the majority of cases bei...
متن کاملThree-dimensional architecture and development of lumber intervertebral discs.
The three-dimensional architecture of the collagen framework of human lumbar intervertebral discs was studied with scanning electron microscopy and polarized light microscopy concentrating on the fibrillar interconnection between the intervertebral disc and the vertebral bodies. The fibrillar framework of the annulus fibrosus and the cartilage end-plates encircled the nucleus pulposus as a clo...
متن کاملSympathetic afferent units from lumbar intervertebral discs.
To clarify the pathomechanisms of discogenic low back pain, the sympathetic afferent discharge originating from the L5-L6 disc via the L2 root were investigated neurophysiologically in 31 Lewis rats. Sympathetic afferent units were recorded from the L2 root connected to the lumbar sympathetic trunk by rami communicantes. The L5-L6 discs were mechanically probed, stimulated electrically to evoke...
متن کاملAn immunohistochemical study of mechanoreceptors in lumbar spine intervertebral discs.
There are limited data concerning mechanoreceptors in normal human lumbar intervertebral discs. The aim of our study was to determine the types of mechanoreceptors in the two lower intervertebral discs in normal adult cadaveric donors and to review the literature. Twenty-five lumbar (L4-5 and L5-S1) intervertebral discs were retrieved from 15 fresh cadavers. We utilized immunoreactivity against...
