Degenerative Disc Disease (DDD) - Treatment and Condition Flashcards
What is DDD?
Degeneration of the annular fibers of the intervertebral disc.
What are other terms used in reference of DDD?
Spondylosis - Degenerative changes in the facet joint.
Slipped Disc - Lay term for Disc herniation.
Lumbago - General, non-specific term for low back pain.
Sciatica - …
What are causes for DDD?
Chronic overloading of the disc leading to annular fiber microtearing and migration of nucleus.
What are contributing factors that lead to DDD?
Trauma, Mm imbalance, Postural Dysfunction, Poor blood supply to disc.
What are the Stages of DDD?
Dysfunction stage, Instability stage, Stabilization stage.
What is the Dysfunction stage of DDD?
Biomachanical changes over time result in weakness, bulging and minor tears in the annulus fibers, which heal slowly.
May be symptomatic, may be painful chronic facet joint irritation, joint effusion and mm spasms.
What is the Instability Stage of DDD?
Posterior annular fibers and joint capsule become weak causing them to become hypermobile.
Tissue changes in this stage are considered permanent.
What is the Stabilization Stage of DDD?
Loss of disc material and decreased disc hight, intervertebral foramen narrows, the joint capsules and post ligamentous fibers.
Stenosis may occur and degeneration may spread to other vertebral levels.
What stage of DDD is considered to be reversable?
The first stage (Dysfunction Stage).
What does the symptom picture for Acute Disc herniation look like?
Acute disc herniation can occur at any stage, but most commonly at the end of Dysfunction or the start of Instability.
Were does pain arise from in an acute disc herniation?
Pain arises from compression of pain sensitive structures by the protrusion.
When pain arises from compression of pain sensitive structures near a disc herniation, what are these structures?
This could include:
Nn roots, ligaments, dura matter, and Bv’s.
Pain is usually worse in the morning because the nucleus is still contained in the annulus fibers.
With Disc herniation, when does pain increase?
Pain mostly increases when a person is inactive.
What does AF and PR Rom testing reveal in a client with DDD?
AF PR Rom of ether C-spine or lumbar may reveal reduced ranges, with PR rom having more available range.
What is the most restricted range in a client with DDD?
Spine extension is the most restricted, stiffness is likely, pain may or may not be present.
