Chronic lower back pain is defined as back pain that lasts more than three months. [13] The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people recovered by six weeks. [2] Normal activity should be continued as much as the pain allows. [2]
Bertolotti's syndrome is a commonly missed cause of back pain which occurs due to lumbosacral transitional vertebrae (LSTV). It is a congenital condition but is not usually symptomatic until one's later twenties or early thirties. [1] However, there are a few cases of Bertolotti's that become symptomatic at a much earlier age.
Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
After the conus medullaris (near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower), the spinal canal contains a bundle of nerve fibers (the cauda equina or "horse-tail") that branches off the lower end of the spinal cord and contains the nerve roots from L1–L5 and S1–S5. The nerve roots from L4–S4 join in the sacral plexus ...
Spondylolysis is a common cause of low back pain in preadolescents and adolescent athletes, as it accounts for about 50% of all low back pain. [7] It is believed that both repetitive trauma and an inherent genetic weakness can make an individual more susceptible to spondylolysis. [4]
Back pain (Latin: dorsalgia) is pain felt in the back. It may be classified as neck pain (cervical), middle back pain (thoracic), lower back pain (lumbar) or coccydynia (tailbone or sacral pain) based on the segment affected. [1] The lumbar area is the most common area affected. [2]
The fifth lumbar spinal nerve 5 (L5) [5] originates from the spinal column from below the lumbar vertebra 5 (L5). L5 supplies many muscles, either directly or through nerves originating from L5. They are not innervated with L5 as single origin, but partly by L5 and partly by other spinal nerves. The muscles are: gluteus maximus muscle mainly S1
In the upper lumbar region the lamina are taller than wide, but in the lower lumbar vertebra the lamina are wider than tall. The lamina connects the spinous process to the pedicles. The vertebral foramen within the arch is triangular, larger than the thoracic vertebrae , but smaller than in the cervical vertebrae .
