Description

This video explains Cervical Radiculopathy and Cervical Herniations. When herniations begins to affect the nerves and spinal cord this is called Cervical Radiculopathy. This video highlights the history, epidemiology, and treatment options both conservative and surgical.

Radiculopathy is not a specific condition, but rather a description of a problem in which one or more nerves are affected and do not work properly The emphasis is on the nerve root (“Radix" = "root“ ). This can result in radicular pain, weakness, numbness, or difficulty controlling specific muscles.

Cervical Spondylosis: Progressive degenerative changes that develop slowly over time, this alters the spinal biomechanics from the loss of shock absorption properties of intervertebral discs. This leads to secondary changes in surrounding structures. Dysfunction  Instability  Stabilization (Marginal Osteophytes)

Dysfunction  Instability  Stabilization (Marginal Osteophytes)

Three distinct clinical syndromes can result: Type I: Cervical Radiculopathy: Cmprsn +Inflammation of Spinal Nerve with symptoms that correspond to the level involved Type II: Cervical Myelopathy: Cord involvement Type III: Axial Joint Pain (Mechanical neck pain, “discogenic pain”, facet syndrome, painful instability

October 24,1892 20 YO “builder who under the influence of alcohol, fell off his van on to the road striking his right shoulder.” Over the next 2months he gradually lost control of legs and sphincters Dr Horsley performs the first Laminectomy of 6 th Cervical Vertebra. The Spinal cord was found to be compressed by a transverse ridge projecting backwards from the body of the vertebra. Complete recovery by September of that year

Cervical spondylosis. An update.

January 1895, Viennese newspapers heralded Professor Röntgen's new “ray,” which would become the basis for the science of roentgenography.

Cervical spondylosis and cord impingement was originally described by Stookey in 1928 He attributed compression of the cord by “extradural chondromas” cartilaginous nodules , which they thought were the same findings as some people had on their ears 1934 Peet, MM and Echols, DH showed “chondromas” were disc protrusions Lord Brain, F.R.S., D.M., F.R.C.P. (1895-1966)

The facet joints themselves can account for significant neck pain. The facet joint capsules have free nerve endings which send referred pain into these specific distributions. This is why many of the patients we see every day have neck/ shoulder/scapular pains. Dwyer Spine 15: 453-7, 1990.

With my background as a Third grade teacher I always make it a point to build a foundation concept before moving on to complex ideas. As a Spine surgeon I want the most vantage points on an object, this gives me a frame of reference and helps to construct the anatomy in my mind.

As a Spine surgeon I want the most vantage points on an object, this gives me a frame of reference and helps to construct the anatomy in my mind.

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. 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

There are seven bones which make up the cervical spine. Each vertebral body ( these look like blocks) are separated by intervertebral discs which function as shock absorbers.

 

A Herniated disc A herniated disc (sometimes called a slipped disc) is the most common cause of sciatica. Discs are the cushions between the bones in the back. They act like "shock absorbers" when we move, bend, and lift.

There is a tough ring around the outside called the Annulus Fibrosus , and a thick almost crabmeat like center inside called the Nucleus pulposus.

There is a tough ring around the outside called the Annulus Fibrosus , and a thick almost crabmeat like center inside called the Nucleus pulposus.

If the outer edge of the disc ruptures, the center can push through and put pressure on the exiting nerve, leading to the pain of sciatica (referred to as a Herniated nucleus pulposus or disc herniation).

The pain is not improving after several days or seems to be getting worse. You are younger than 20 or older than 55 years and are having sciatica for the first time. You presently have cancer or have a history of cancer. You have lost a large amount of weight recently or have unexplained chills and fever with back pain. You continue to have trouble bending forward after more than a week or two. You notice weakness is getting more pronounced over time. You develop any new onset weakness, such as a drop foot. You are dropping items, have noticed a loss of dexterity, difficulty opening jars.

You are dropping items, have noticed a loss of dexterity, difficulty opening jars.

The pain is unbearable, despite trying first aid methods , NSAIDs, rest, relaxation, and bedrest. The pain follows a violent injury, such as a fall from a ladder or an automobile crash. The pain is in the back of your chest. You are unable to move or feel your legs or feet. You lose control of your bowels or bladder or have numbness in your genitals. You have a high temperature (over 101°F).

Surgery should be a last resort, when conservatives measures fail. In some cases surgery needs to be done sooner than later, or even urgently, depending on the physical exam, history, neural deficits, and size of the herniation.
