Intervertebral Disc Degeneration

Dr Ozello's Sports Medicine Report: Intervertebral Disc Degeneration *Disclaimer: Viewing this video does not take the place of seeing a medical professional. Please visit a medical professional for evaluation, diagnosis and treatment. Never perform an exercise that elicits or intensifies symptoms. If an exercise elicits or intensifies symptoms, stop immediately and use a viable substitute. Always perform all exercises through a symptom free range of motion. Begin your training at your current health, fitness and strength levels. Increase intensity in small gradual calculated increments. Intervertebral Disc Degeneration Common condition with prevalence estimates between 50–64% for age 65 and up. Painful condition that limits motion and activity. Intervertebral disc degeneration is a main contributor to neck and back pain. Degenerative process characterized by loss of water. Results in disc space narrowing. Disc degeneration is not exclusive to older populations. A degenerated disc can be found among young healthy discs in a young individual. Anatomy Intervertebral Disc (IVD) Located between the Vertebral bodies. Function: Provides a measure of shock absorbing protection to the spinal column and appropriate stability for the spine during load bearing activities. Components: Nucleus pulposus, annulus fibrosus and vertebral endplates. Nucleus Pulposus: Innermost component. Avascular. Comprised largely of water. Also, contains cartilage cells and collagen fibers. Gel-like and has consistency of toothpaste. Contains proteoglycans, which attract water to support the disc's structural integrity. Annulus Fibrosus: Fibers are arranged in alternately oriented concentric ring layers which contributes to the tensile strength of the annular ring. Disc degeneration may be caused by genetic predisposition, injury, aging and environmental factors, such as smoking, obesity and mechanical overuse or any combination of these factors. Intrinsic Contributing Factors Osteoporosis, osteopenia and compression fractures. Endplate thinning and fracture, changes in vertebral body, endplate sclerosis and facet cartilage erosion. Aging and laxity of spinal ligaments and atrophy of spinal muscles. Two Types Endplate Driven: Involves endplate defects and inwards collapse of annulus. Mostly in upper lumbar and thoracic spine. Often starts to develop before age 30. Usually leads to moderate back pain. Associated with compressive injuries. Annulus Driven: Involves a radial fissure and/or disc prolapse. Mostly affects lower lumbar spine. Develops progressively after age 30. Usually leads to severe back pain and sciatica. Associated with repetitive bending and lifting. Imaging X-Rays: Osteophytes, end‐plate sclerosis and disc space narrowing. Preserving healthy joints, particularly intervertebral discs is vital for maintaining mobility in old age. Prevention and Rehabilitation. Motion exercises. Swimming and pool exercises. Fitball exercises (Only if balance is good). Spine stretching exercises. Spine decompression exercises.
