What is the posterior thecal sac?

The thecal sac, enclosing the spinal cord and cauda equina, sits within a protective ring of bone consisting of the vertebral body anteriorly, and the pedicles, lamina, and spinous process posteriorly. The latter three structures form what is collectively referred to as the posterior arch.

What is mild effacement of the thecal sac?

Compression of the thecal sac means the protective membrane covering the spinal cord is experiencing extra pressure, according to Merck Manuals. Effacement of the thecal sac means that the thecal sac is being shortened or narrowed, according to the Free Dictionary.

Abstract. Posterior protrusion of one of the lumbar intervertebral discs into the spinal canal is one of the most common mechanical derangements of the low back in patients suffering from intractable sciatic pain.

What exercises are bad for bulging discs?

Herniated Disc: Exercises to Avoid

What does it mean to have a posterior bulging disc?

Dan Cavallari A posterior bulging disc, or herniated disc, occurs when a spinal disc beings to bulge. A posterior bulging disc, also known as a herniated disc, occurs when a spinal disc that sits between vertebrae begins to bulge due to compression. This condition can be painful and may end up limiting the mobility of the sufferer.

Can a bulging disc lead to thecal sac impingement?

A bulging disc, osteophytes, or osteoarthritis can lead to impingement, or something pressing on another structure. The terminology associated with this problem is thecal sac impingement, or a herniated disc “providing a mass effect”, “compressing”, “displacing”, or “encroaching on the thecal sac”.
