Lumbar spondylosis includes all degenerative conditions affecting the discs, vertebral bodies, and associated joints of the lumbar vertebrae. The bones and cartilage that make up the backbone and neck gradually develop wear and tear in aging which includes Dehydration of the discs which act like cushions between the vertebrae of the spine . Herniated discs. Bone spurs. Stiff ligaments. By the age of 40, most people's spinal discs begin drying out and shrinking, which allows more bone-on-bone contact between the vertebrae. Cracks often appear, leading to bulging (herniation) disks which sometimes press on the spinal cord and nerve roots. Disk degeneration causes production of extra amounts of bone in a misguided effort to strengthen the spine. These bone spurs can sometimes pinch the spinal cord and nerve roots. Ligaments are cords of tissue that connect bone to bone. Spinal ligaments stiffen with age, causing limitation in movements.
Lumbar spondylosis in Siddha medicine is Urusthambam vatham in which the lower limbs are affected causing numbness with radiating pain.urusthamba vatham is well managed by siddha medicine without surgical intervention.
