Focal ligamentum flavum
hypertrophy with ochronotic deposits: an unusual cause for neurogenic claudication in alkaptonuria.
hypertrophy or infolding refers to abnormal thickening and buckling of the ligamentum flavum
as a result of degenerative changes in the lumbar spine.
Management of thoracic myelopathy caused by ossification of the posterior longitudinal ligament combined with ossification of the ligamentum flavum
– A retrospective study.
Only the ligamentum flavum
and, if necessary, a very small portion of lamina was excised to expose the affected disc space.
4 applied spinal anesthesia in sitting position at lumbar L3-L4 level and found skin-anterior ligamentum flavum
distance and spinal needle depth as (5.
In this technique, interspinous and supraspinous ligaments are put aside, and ligamentum flavum
is the first resistance with which one might encounter.
The radiographic narrowing is caused by three pathoanatomic abnormalities occurring together: thickening of the normally paper-thin ligamentum flavum
, facet joint osteoarthritis, and disk protrusion.
Lumbar spinal stenosis (LSS) is the narrowing of the central canal and, often, the lateral recess due to facet joint hypertrophy, thickening and bulging of the ligamentum flavum
, bulging of an intervertebral disc, osteophyte formation, or spondylolisthesis.
A large ligament often involved in spinal stenosis is the ligamentum flavum
, which runs as a continuous band from lamina to lamina in the spine.
Rather than requiring a needle stick for each percutaneous lead or requiring a laminotomy for S-Series paddle leads, the Epiducer system enables physicians to gradually dilate the ligamentum flavum
through a percutaneous approach, allowing unprecedented access to the epidural space.
Thoracic stenosis may result from facet hypertrophy, anterior disc protrusion, spondylotic spurs, ossified posterior longitudinal ligament, ligamentum flavum
hypertrophy or ossification.
Background: Ossification of the ligamentum flavum
(OLF) is being increasingly recognized as a cause of thoracic myelopathy.
