What is Dermatomal distribution?
Dermatomal distribution involves an area of skin supplied with sensory innervation by a particular nerve root. Dermatomal distributions do not cross the midline of the body.
What is lumbosacral Radiculitis?
Lumbosacral radiculopathy is a condition in which a disease process causes functional impairment of one or more lumbosacral nerve roots. The most common cause is structural (ie, disc herniation or degenerative spinal stenosis) leading to root compression.
What is bilateral radiculopathy?
Radiculopathy describes a range of symptoms produced by the pinching of a nerve root in the spinal column. The pinched nerve can occur at different areas along the spine (cervical, thoracic or lumbar). Symptoms of radiculopathy vary by location but frequently include pain, weakness, numbness and tingling.
What dermatomes are responsible for sensation along the back?
5 lumbar dermatomes (L1-L5) that supply sensation from these spinal nerves in the lower limb (leg, foot, hip, etc.) – “L” refers to the five lumbar vertebrae, the disks below them, and the corresponding area of the lower back.
Can radiculopathy be bilateral?
Radiculopathy and sciatica both are typically on one side of the body. Neuropathy, on the other hand, is quite different. Often, this is bilateral and can be caused not just by a spinal issue but metabolic or autoimmune issues as well.
What causes bilateral cervical radiculopathy?
The most common causes of cervical radiculopathy are when a nerve root becomes inflamed or damaged due to a nearby bone spur or cervical herniated disc, such as from spinal degeneration over time or an injury. Many other less common causes of cervical radiculopathy are possible, such as infection or tumor.
What is the L2 Dermatome distribution?

What are the lower limb dermatomes?
The lower limb dermatomes are the areas of skin on the lower limb that are supplied by the afferent fibres of a single spinal posterior nerve root. An approximate guide is as follows: ROOT AREA SUPPLIED L2 upper thigh L3 around the knees L4 medial aspect of the leg
What is the distribution of dermatomal distribution in the lower extremities?
Dermatomal distribution in the lower extremity has a spiral arrangement stemming from the rotation of the limb as an adaptation to the erect position during development (see the following image). Dermatomes of the extremities.
How are the dermatomes numbered?
Your dermatomes are numbered according to what spinal nerves they correspond to. Below, we will outline each dermatome of the lower limb, and also the area of the body that is associated with that particular dermatome. L2 to S5 spinal nerves supply the lower limb.
