Thecal sac. The dura mater and arachnoid mater are collectively called the dural sac or the thecal sac. This sac covers the conus medullaris, cauda equina, and each individual spinal nerve root as it courses out of the cauda equina and travels into the intervertebral foramen (bony opening through which the nerve exits the spinal canal). 2 Darby ...
looking over the findings of my mri, it says: c6-c7 shows a central spur with ventral effacement of the thecal sac. what does that mean exactly?: A bone: Spur in the low neck pressing on the sac which contains the ce
Back pain: The thecal sac covers the spinal cord. It becomes thinned , or effaced, when pressure is applied to it from degenerative disk disease of the spine. In other words, the bulging disk squeezes the sac as it presses towards the spinal cord.
what is effacement of the ventral thecal sac?: Back pain: The thecal sac covers the spinal cord. It becomes thinned ,
at the l3-l4 in lower back what is a broad-based disc osteophyte complex? at l4-5 in the lower back what is broad-based osteophyte complex causing mild effacement of the ventral thecal sac?: Complex: This term describes disc material encased in bony and scarred
The C6-C7 spinal motion segment bears the primary load from the weight of the head and supports the lower part of the neck. This motion segment is susceptible to degeneration, trauma, and intervertebral disc problems.
Effacement of the ventral thecal sac means pressure is upon the front of the sac (producing a flattening effect) most likely from a disc protrusion. Foramen means hole (where the nerve comes out ...
A synovial cyst is a fluid-filled sac that develops as a result of degeneration in the spine. Because a synovial cyst develops from degeneration it is not often seen in patients younger than 45, and is most common in patients older than 65 years old.
The Course of Central Canal Stenosis. Typically, stenosis is seen in up to 80% of people above 60 years of age, with an estimated 5% having coexisting cervical and lumbar stenosis (also called tandem spinal stenosis). 3 Melancia JL, Francisco AF, Antunes JL.
what does mild l4-l5 diffuse disc bulging with anterior thecal sac effacement mean?: Generally nothing: It means there are mild osteoarthritic changes in t
