How long is epidural space is found from skin ( cervical area, thoracic ànd ĺumbar area)

1 answer

The epidural space is located between the dura mater and the inner bony surface of the vertebrae. The depth of the epidural space from the skin varies by anatomical region. Here are approximate measurements for the cervical, thoracic, and lumbar regions:

  1. Cervical Area: The epidural space is typically about 3 to 4 centimeters deep from the skin in the cervical region.

  2. Thoracic Area: In the thoracic region, the depth from the skin to the epidural space is approximately 4 to 5 centimeters.

  3. Lumbar Area: In the lumbar region, the depth is generally around 5 to 6 centimeters from the skin.

These measurements can vary based on individual anatomy, body habitus, and the specific location where the puncture is made. It's important for medical professionals to consider these variations when performing procedures such as epidural anesthesia or spinal taps.
