What is a posterior Hemilaminectomy?

A posterior lumbar laminectomy, which is also called a decompression, is done to treat pain caused by degenerative conditions in the lower back. Disc degeneration, bone spurs, and other conditions can cause narrowing and pressure on the spinal nerves (radiculopathy) exiting the spine.

What is the function of the rongeur?

Rongeurs are like pliers with a heavy, pointed jaw. With their heavy contrsuction, rongeurs are used for gnawing holes in bones during surgery. The scoop shaped tip of the rongeur is used for gouging the bone. This could be neurosurgery where the surgeon must remove part of the skull to expose the brain.

What is a Kerrison used for in surgery?

A Kerrison rongeur is used to notch the midline on the inferior aspect of the graft to accommodate the spinous process of C2 for a secure fit.

What is posterior decompression?

Posterior spinal decompression surgery is performed from the back of the spine. This surgery makes the spine unstable and therefore another procedure, spinal fusion is performed to stabilize the spine. Spinal fusion uses bone grafts, rods, plates or screws to join together two separate vertebrae in the spine.

What is posterior cervical decompression and fusion?

Posterior cervical decompression and fusion is a technique that allows for decompression of multiple segments of the cervical spine in patients with multi-level stenosis. It also involves placement of screws in the lateral masses, connected by a rod to afford immediate stability to create a fusion.

What is a pituitary rongeur used for?

Used to cut and remove vertebral discs in the minimally invasive, lateral approach to the spine. Used to cut and remove vertebral discs in the minimally invasive, lateral approach to the spine.

What is a rongeur in medical terms?

Medical Definition of rongeur (Entry 1 of 2) : a heavy-duty forceps for removing small pieces of bone or tough tissue.

What is dorsal decompression?

Spinal decompression can be performed anywhere along the spine from the neck (cervical) to the lower back (lumbar). The surgery is performed through an incision in the back (posterior) muscles. The lamina bone forms the backside of the spinal canal and makes a roof over the spinal cord.

What is posterior cervical decompression?

Posterior Cervical Decompression is a surgical procedure to relieve bony pressure on the spinal canal and/or the spinal nerves. This can also involve removing disc material to relieve pressure on the nerves.

What is posterior cervical?

Posterior Cervical Fusion (PCF) is the general term used to describe the technique of surgically mending two (or more) cervical spine bones together along the sides of the bone using a posterior (back of the neck) incision. Bone graft is placed along the sides the spine bones, which over time, fuses (mends) together.

What is a Kerrison rongeur used for?

The Kerrison rongeur used to remove bone from smaller areas of the spine. Its features include Variable jaw widths, including 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm. Two jaw slants (40o and 90 o), used for up or down biting (most commonly used one – up biting).

What is the difference between Kerrison rongeur and duckbill?

used to remove the spinous process like the boney projections on each vertebra where the muscles and ligaments attach to the spine. duckbill will have a slightly pointed side. The Kerrison rongeur used to remove bone from smaller areas of the spine. Its features include Variable jaw widths, including 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm.

What is a pituitary rongeur?

Pituitary rongeur used to remove disc and tissue in small spaces. Available in several jaw widths, including 2 mm, 3 mm, and 4 mm. Some rongeur, such as the Casper pituitary, have serrated jaws to help remove disc and tissue.
