Spinal flexion loads the anterior aspect of the spinal disc, driving the nucleus pulposus posteriorly against the stretch-taut annular fibers. This can increase a bulging or herniated disc pathology. In today’s video, let’s have a look at Anterior and Posterior …
A pathologic disc can compress the sciatic nerve resulting in sciatica. Although any pathologic disc is potentially serious.
The “action” of a ligament is similar to that of an antagonist muscle. If either is tight/taut, it restricts motion to the opposite side.
The low back is defined by the lumbar spine, composed of 5 vertebrae, named L1-L5. The pelvis is defined by the bones of the pelvic girdle.
The “action” of a ligament is similar to that of an antagonist muscle. If either is tight/taut, it restricts motion in the opposite direction.
One cause of a pathologic disc (e.g., bulge, herniation) is excessive flexion postures, which drive the nucleus posteriorly against the taut annular fibers.
This article addresses the causes of the three different types of pathologic disc conditions: degenerated disc, bulging disc, and herniated disc.
