Description

This video explains Lumbar Microsurgical Minimally Invasive Decompression in Detail. When degenerative disc disease begins to affect the spine this is called degenerative disc disease. This video highlights the history, epidemiology, and treatment options both conservative and surgical. If you or someone you know needs to be seen in regards to Lumbar Disc Replacement feel free to look us up online www.beverlyspine.com or www.santamonicaspine.com OR call toll free 1-8SPINECAL-1

Here is the normal spine of an 18 year old cadaver male. Notice the nice ample, round space available for the spinal cord and neural elements

With time the space begins to narrow slowly as Arthritis develops

More and More Bony overgrowth occurs

More and More Bony overgrowth occurs

With time the space begins to narrow to an almost Triangular space and can compress the neural elements within

There can be side to side differences meaning the left side may be tighter than the right and vice versa

With my background as a Third grade teacher I always make it a point to build a foundation concept before moving on to more complex ideas. I would like to take a moment to build some foundations before continuing to discuss MRIs.

I would like to take a moment to build some foundations before continuing to discuss MRIs.

Here is what I mean by a foundation concept. You will see side view images and top down images throughout this presentation and on your MRIs. This can be hard to grasp unless we stop and point a few things out initially The Sagittal view is also called the lateral view and this is pictured here it displays the spine as viewed from the SIDE.

This can be hard to grasp unless we stop and point a few things out initially The Axial view is a top down view of the spine. This image repsents a slice obtained as if an Axe were to chop you, therefore the name Axial view.

Next we will review some basic anatomy Some images will be in the Sagittal plane

Joint Facet Nucleus Pulposus Right Nerve Root Left Nerve Root As you can see here on MRI and CT scans the Facet joints end up looking like the buns of a hamburger. Its just the way the happen to look when they are sliced in this plane. We will show you this on some examples later Annulus Fibrosus Axial View of the Disc and Neural elements

On this diagram The number 2 is the nerve exiting the spine through a hole called the Foramen From here the nerve will provide sensation and strength to the legs

If the Nerve is compressed within the spine or foramen the nerve can refer pain to buttock, thigh, leg, calf or foot. Where does your pain refer to???

Traditional Surgery was a WIDE LAMINECTOMY. However history has shown that this may risk destabilizing the spine

With the traditional Laminectomy the entire lamina and the Spinous process of each spinal segment was removed. This was shown to cause an unstable spine in some cases

An Incision is made on your lower back The muscles on your back are not cut instead with this approach they are simply moved out of the way. This is why patients feel pain after surgery, because we hold these muscles out of the way to do surgery and you wake up you will have a muscle sprain

At this point the incision is so small we need to use a surgical microscope to allow for the best visualization. There are two eyepieces for the microscope and you will have two Spinal surgeons there for your surgery. Dr Pazmino and Dr Lauryssen.

Once we have exposure we remove the thickened ligamentum flavum. This is also known as the yellow ligament. It has two layers and must be removed to begin any spinal surgery

The wound is next thoroughly washed with an antibiotic solution and closed with Absorbable sutures Final closure is performed using Dermabond. Dr Pazmino’s brother is a plastic surgeon. www.miamiaesthetic.com. This allows patients to shower the same day of surgery with NO DRESSING !!!!
