Lumbar degeneration

The lumbar spine is composed of five vertebral bodies stacked on top of each other. Five pairs of lumbar sacral nerves protrude from the neural foramen located on the posterior side of the vertebrae. These sacral nerves and the nerves separated from the lower sacrum constitute the largest peripheral nerve in the human body. — The sciatic nerve. With the increase of age and the proliferation of bone spurs, it presses on the neural foramen, which causes annoying symptoms such as back pain and sciatica.
