Epidural Space Of Spinal Cord

The spinal canal enclosed within these structures is also known as the epidural space apart from the central portion occupied by the dural sac and its contents.

Epidural space of spinal cord. It is typically 4 6 mm in depth 4. 51 2 is bordered by the posterior longitudinal ligament and vertebral. Radiocontrast agents and therapeutic e g. The epidural space fig.

That space is known as the intervertebral foramen. Epidural space neuraxial anesthesia. Cervical epidural nerve block. The epidural space protects the spinal cord from injury.

Transforaminal epidural injections sometimes called selective nerve root blocks are performed by entering the epidural space through the opening through which the nerve root which branches from the spinal cord exits. The epidural space is entered when a needle passes through the ligamentum flavum. Although it is rare it can be fatal if left untreated. The dura mater contains the arachnoid mater.

The epidural route is frequently employed by certain physicians and nurse anaesthetists to administer local anaesthetic agents and occasionally to administer diagnostic e g. Epidural near the dura the outermost protective covering of the spinal cord abscess a collection of pus infected material a spinal epidural abscess is an infection in the area between the bones of the spine or on the outer covering of the spinal cord. This part of the spinal anatomy consists of the area between the dura mater the tough fibrous tissue that surrounds the spinal cord and cerebrospinal fluid and the lining of the vertebral canal. The spinal epidural space is located in the spinal canal between the spinal dura mater and the vertebral column and extends from the foramen magnum to the sacral hiatus.

Between the arachnoid and the pia mater which is applied to the spinal cord is cerebrospinal fluid. In anatomy the epidural space is the potential space between the two layers of the dura mater the outermost meningeal layer that covers the brain and spinal cord. Epidural administration from ancient greek ἐπί on upon dura mater is a medical route of administration in which a drug such as epidural analgesia and epidural anaesthesia or contrast agent is injected into the epidural space around the spinal cord.

The epidural space is an area of spinal anatomy that is located between the vertebral canal and the spinal cord. In different people the size of the epidural space can vary.
