	'''~~Epidural~~ space''' is an anatomical ~~feature present in the human body. It is the area between~~ the [[dura mater]]~~, a thick membrane that surrounds~~ the ~~brain and~~ spinal cord, and the vertebral ~~wall, containing fat and small blood vessels~~. ~~The~~ space ~~is located just outside~~ the ~~dural sac and is filled with cushioning fat and a network~~ of ~~veins~~.		== Epidural Space ==

			[[File:Gray767.png\|thumb\|right\|Diagram of the epidural space]]

			The '''epidural space''' is an anatomical space that lies outside the [[dura mater]] of the [[spinal cord]] and within the [[vertebral column]]. It is a potential space that can be accessed for various medical procedures, most notably for the administration of [[epidural anesthesia]].

	== Anatomy ==		== Anatomy ==
	The epidural space is located in the spinal canal, which runs the length of the spine. It is bounded by the [[ligamentum flavum]] posteriorly, the vertebral body and intervertebral discs anteriorly, and the pedicles of the spine laterally. The space contains loose fatty tissue, and a network of large, thin-walled veins called the [[internal vertebral venous plexuses]].

	== Clinical ~~significance~~ ==		The epidural space is located between the outermost layer of the meninges, the dura mater, and the inner walls of the vertebral canal. It extends from the [[foramen magnum]] at the base of the skull to the [[sacral hiatus]] at the end of the vertebral column.
	The epidural space is clinically significant ~~because it is a potential space that can be created to administer~~ [[~~epidural~~ anesthesia]] ~~or analgesia. This~~ is a common procedure in childbirth and ~~for pain management in~~ certain types of surgery ~~or cancer pain~~. ~~The~~ epidural space ~~can also be accessed for diagnostic or therapeutic spinal injections~~.
			=== Contents ===

			The epidural space contains:

			* [[Adipose tissue]]
			* [[Lymphatics]]
			* [[Blood vessels]], including the [[internal vertebral venous plexus]]
			* [[Spinal nerve roots]]

			== Clinical Significance ==

			The epidural space is clinically significant for several reasons:

			=== Epidural Anesthesia ===

			[[Epidural anesthesia]] is a common procedure used to provide pain relief during [[childbirth]] and certain types of [[surgery]]. A needle is inserted into the epidural space, and anesthetic agents are administered to block nerve impulses, providing regional anesthesia.

			=== Epidural Abscess ===

	~~== Epidural anesthesia ==~~		An [[epidural abscess]] is a collection of pus that can form in the epidural space, often due to infection. It can compress the spinal cord and nerves, leading to neurological deficits if not treated promptly.
	[[~~Epidural anesthesia~~]] is a form ~~of regional anesthesia involving injection of drugs through a catheter placed into~~ the epidural space. ~~The injection~~ can ~~cause both a loss of sensation (anaesthesia) and a loss of pain (analgesia), by blocking the transmission of signals through nerves in or near~~ the spinal cord.

	== ~~Complications~~ ==		=== Epidural Hematoma ===
	~~Complications of epidural anesthesia can include~~ [[epidural hematoma]]~~, [[~~epidural ~~abscess]]~~, ~~and [[spinal headache]]~~. ~~These complications are rare, but~~ can ~~be serious. They are usually treated with medications, procedures, or surgery~~.
			An [[epidural hematoma]] is a collection of blood in the epidural space, usually due to trauma. It can cause compression of the spinal cord and requires urgent medical intervention.

'''Epidural space''' is an anatomical feature present in the human body. It is the area between the [[dura mater]], a thick membrane that surrounds the brain and spinal cord, and the vertebral wall, containing fat and small blood vessels. The space is located just outside the dural sac and is filled with cushioning fat and a network of veins.

== Anatomy ==
The epidural space is located in the spinal canal, which runs the length of the spine. It is bounded by the [[ligamentum flavum]] posteriorly, the vertebral body and intervertebral discs anteriorly, and the pedicles of the spine laterally. The space contains loose fatty tissue, and a network of large, thin-walled veins called the [[internal vertebral venous plexuses]].

== Clinical significance ==
The epidural space is clinically significant because it is a potential space that can be created to administer [[epidural anesthesia]] or analgesia. This is a common procedure in childbirth and for pain management in certain types of surgery or cancer pain. The epidural space can also be accessed for diagnostic or therapeutic spinal injections.

== Epidural anesthesia ==
[[Epidural anesthesia]] is a form of regional anesthesia involving injection of drugs through a catheter placed into the epidural space. The injection can cause both a loss of sensation (anaesthesia) and a loss of pain (analgesia), by blocking the transmission of signals through nerves in or near the spinal cord.

== Complications ==
Complications of epidural anesthesia can include [[epidural hematoma]], [[epidural abscess]], and [[spinal headache]]. These complications are rare, but can be serious. They are usually treated with medications, procedures, or surgery.
