What is Vertebrogenic syndrome?
Vertebrogenic Pain Syndrome is an acute or chronic pain in the back, and can include thoracic, lumbar, sacral or adjacent regions. Pain can be of many qualities and causes, and treatments may include physical therapy, spinal manipulations, injections and in some cases, surgical correction.
What is the function of the dermatome?
Spinal nerves help to relay information from other parts of your body to your central nervous system. As such, each dermatome transmits sensory details from a particular area of skin back to your brain. Dermatomes can be helpful in evaluating and diagnosing conditions affecting the spine or nerve roots.

What is radicular syndrome?
Radicular syndrome results in pain and other symptoms such as numbness, tingling and weakness in the arms or legs. It is caused by compressed or irritated nerve roots. The nerve roots are branches of the spinal cord that carry nerve signals out to the rest of the body at each level along the spine.
What causes dermatome pain?
Dysfunction or damage to a spinal nerve can trigger symptoms in the corresponding dermatome. Nerves damage or dysfunction may result from infection, compression, or traumatic injury. Doctors can sometimes use the severity of symptoms in a dermatome to determine the extent and location of nerve damage.
Are dermatomes real?
A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root. Examples include somatic dysfunction of the spine or viral infection.
Where are Dermatomes located?
spinal cord
Dermatomes are located in the spinal cord. Myotomes is a group of single spinal nerves that originate from a groups of muscles.
Is radiculopathy the same as sciatica?
When radiculopathy occurs in the lower back, it is known as lumbar radiculopathy, also referred to as sciatica because nerve roots that make up the sciatic nerve are often involved. The lower back is the area most frequently affected by radiculopathy.
How many dermatomes are there in the spinal column?
The 31 spinal column has 31 spinal nerves, which are composed of 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal spinal nerves. There are specific dermatomes for each of these spinal nerves, except the first cervical spinal nerve.
How are dermatomes transmitted to the spinal nerves?
Dermatomes exist for each of these spinal nerves, except the first cervical spinal nerve. Sensory information from a specific dermatome is transmitted by the sensory nerve fibers to the spinal nerve of a specific segment of the spinal cord.
Where are the five dermatomes associated with lumbar nerve roots?
The five dermatomes associated with lumbar nerve roots are: L1: Across the lower back, around the hips, then dipping down to the groin L2, L3: Across the lower back, angling down across the front and inside of the thigh
What’s the difference between a myotome and a dermatome?
The major difference between dermatomes and myotomes are: Myotomes is a group of single spinal nerves that originate from a groups of muscles. How Do Doctors Use Dermatomes to Diagnose Diseases?
