How can dermatomes be used in diagnosis of the location of a spinal injury?

How can dermatomes be used in diagnosis of the location of a spinal injury?

Yes: Dermatomes are maps of the skin based on study of many people. Based on where the skin is numb or sensitive or has abnormal feeling, a physician can tell which nerves or part of the spinal cord are affected. People do vary in what part of the body is supplied by which spinal nerve root, but a trained physician or health care provider can come close. Imaging like MRI can confirm the location. ...Read more

What is the difference between dermatome and peripheral nerve innervations? Which of them carry pain and temperature sensations?

What is the difference between dermatome and peripheral nerve innervations? Which of them carry pain and temperature sensations?

Definitions overlap: A dermatome is an area of skin supplied by sensory neurons that arise from a single spinal nerve ganglion (from a single dorsal root). A peripheral nerve field refers to an area of skin innervated by a single nerve. An area innervated by a single dorsal root is called a dermatome. Both can sense pain and temperature. ...Read more

I've total numbness on the right side of chest to back dermoatome t4-t9. Along T4 can be really painful when agitated. Upper right leg now also day11?

This bothers me: You are describing a problem focally affecting your spinal cord, perhaps a thoracic myelitis, also called transverse myelitis. This can occur with cord compression, viral infections, neuromyelitis optica, multiple sclerosis. This condition needs immediate attention, get to a hospital today. ...Read more

What is the difference between dermatome and the center of the tendon jerk?

What is the difference between dermatome and the center of the tendon jerk?

Not sure...: Not sure i understand your question, but "dermatome" refers to the cutaneous distribution of sensation for a given nerve. I am not familiar with the term "center of the tendon jerk." deep tendon reflexes evaluate a muscle's ability to sense a stimulus and react to it via contraction. ...Read more

I am having shooting pain from L3 to my knee according to a dermatome chart. Nothing makes it worse. It just seems to come and go randomly?

I am having shooting pain from L3 to my knee according to a dermatome chart. Nothing makes it worse. It just seems to come and go randomly?

Things to consider: May have intermittent "tapping" of the L3 nerve root causing sporadic symptoms.
Other potential causes of your symptoms include iliotibial band syndrome (especially if the outer knee) or meralgia paresthetica (especially if pain/tingling is along a vertical stripe over the front outer thigh)
pt can address all of these. Urgent eval warranted if you develop weakness or other true neuro issues. ...Read more

2/12 ago fractured transverse process of L1,2,3 with the that of L2 being shattered still having sharp pain at L2 dermatome. How long to settle?

2/12 ago fractured transverse process of L1,2,3 with the that of L2 being shattered still having sharp  pain at L2 dermatome. How long to settle?

Need to image: The pain should have decreased substantially by 3-4 weeks if simple healing was proceeding, but wonder if more has occurred. Would definitely get both MRI and CAT scan of area to ascertain bone fragments and even a problem with disc rupture in area. ...Read more

I have burnin pain on forearm, started with diffuse tingling couple months ago, do i have cervical radiculopathy? burning not specific to dermatome

I have burnin pain on forearm, started with diffuse tingling couple months ago, do i have cervical radiculopathy? burning not specific to dermatome

Couple thots: Doubt this is due to problem in neck, and rather might wonder about problem with radial nerve if over top or forearm (dorsal interosseus syndrome), but if over inner surface could be median such as pronator syndrome, and even less likely anterior interosseus syndrome. An EMG could help sort this out. ...Read more

81/female, both lower extremity paresthesia(symmetric, buttock~sole, not dependent dermatome)-bursting, shooting pain aggravated standing.

EMG: You will need a thorough exam by either a neurologist or pain physician. Emg study will help determine if it is from the low back or other nerves; sciatic, femoral, poly neuropathy).
If possible, an MRI lumbar will help dtermione if the is a disc pushing on the nerves , in you case l5/s1. Also check piriformis muscle for tenderness and reproducible pain down the leg. ...Read more
