The most common forms are cervical<unk> , which are at the level of the neck, and lumbar<unk> , at the level of the lower back. Thoracic<unk> , at the level of the mid-back, is much less common. In lumbar<unk> , the spinal nerve roots in the lower back are compressed which can lead to symptoms of sciatica (tingling, weakness, or numbness that radiates from the low back and into the buttocks and legs). Cervical<unk>  can be far more dangerous by compressing the spinal cord. Cervical canal<unk>  may lead to myelopathy, a serious condition causing symptoms including major body weakness and paralysis. Such severe<unk>  symptoms are virtually absent in lumbar<unk> , however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. Cervical<unk>  is a condition involving narrowing of the spinal canal at the level of the neck. It is frequently due to chronic degeneration, but may also be congenital or traumatic. Treatment frequently is surgical.
