The L1 and L2 nerves tend to go to the groin region. The L3 nerve to the front of the thigh. The L4 nerve to the shin and instep. The L5 nerve to the top of the foot and big toe. The S1 nerve to the outside and bottom of the foot. The disc normally is composed of 2 parts. These are microscopic and cannot exactly be differentiated on an MRI. The central softer part of the disc is the nucleus and the out layer is the annulus. Normally, the annulus holds the nucleus in the center and there is no contact with the nerve roots. As we get older, changes occur naturally in the spine. The discs tend to lose their water content desiccate. The annulus of the disc may bulge, protrude or herniate.

The bones may develop bone spurs osteophytes. The ligamentum flavum may enlarge hypertrophy. The facet joints may enlarge hypertrophy. The bones may slip on one another subluxation or spondylolisthesis. The result of these changes may narrow the place where the nerve exits the spine foraminal stenosis. These changes may narrow the canal where the nerves reside in the spine central stenosis. Each of these things may happen and not cause any symptoms. Listed are some commonly occurring changes, which may be described in a lumbar MRI report.

The most common levels affected at L and L5-S1 as these are the most mobile levels in the lumbar spine. When we are young, the discs have a lot of water or cushioning in them. As we get older, the disc naturally loses the water and essentially shrinks. These terms are variations of the same concept. Pain is not specifically been linked to this condition. Typically a bulge just means the annulus deviates towards the nerve sac. Bulges are extremely common and rarely cause any pain or symptoms. Many people have them at multiple levels in their spine. Protrusion is a slight progression in which the disc now MAY press into a nerve.

With a herniation, a piece of the nucleus now has exited the disc and may press on a nerve. Of the various intrinsic disc problems, a herniation may have the greatest chance of causing symptoms. However, many patients may have larger herniations, without nerve inflammation, and therefore no symptoms. They are commonly associated with other findings such as disc bulges. The bony edges that attach to the discs can enlarge as the discs bulge and may or may not compress the nerves.

Just as with disc bulges , these are very common and not typically a cause of symptoms in the lumbar spine. Ligamentum Hypertrophy. The ligamentum flavum is a tissue just behind the nerve sac. As we age, this ligament can get bigger or hypertrophy. Depending on how much is enlarges, it could press on the nerves and potentially cause symptoms. Usually, the ligamentum hypertrophies in combination with a disc bulge. The facets are the joints in the back that help the spine move. The spine is essentially a three-legged table. The disc is the largest leg in the front. The two facets are the two back legs. As we age, the facets can become larger and may, or may not, press into the nerves.

This may, or may not, cause pain in the legs or back. These two terms refer to bones slipping over one another. Everywhere in the spine the bones should be aligned. As we age, the ligaments holding the bones in place can loosen and allow the bones to slip. This can also occur from a fracture, either congenitally or from trauma. In either case, this condition may or may not be symptomatic. The two lowest segments in the lumbar spine, L5-S1 and L4-L5 , carry the most weight and have the most movement, making the area prone to injury.

In between vertebrae are spinal discs, which cushion the joints of the spine and provide support. Discs in the lumbar region of the spine are most likely to herniate or degenerate, which can cause pain in the lower back, or radiating pain to the legs and feet. The spinal cord travels from the base of the skull to the joint at TL1 , where the thoracic spine meets the lumbar spine.

At this segment, nerve roots branch out from the spinal cord, running from the lower back through the back of the leg, and down to the toes. Some lower back conditions may compress these nerve roots, resulting in pain that radiates to the lower extremities, known as radiculopathy. Lumbar Spine Anatomy and Pain.
