The disk is thicker anteriorly, contributing to normal cervical lordosis, and the uncovertebral joints in the posterior aspect of the body define the lateral extent of most surgical exposures. The cervical spine is much more mobile than the thoracic or lumbar regions of the spine. For this reason, C7 is often referred to as the vertebra prominens. Panjabi MM, Oxland TR, Parks EH. Nonsurgical treatment is the first approach in patients with common neck pain not involving trauma. Symptoms include: Did you know you can support education and research for conditions like cervical stenosis while you shop, at no extra cost to you?Register with AmazonSmile to designate the NREF as your charity, and a percentage of your purchase is donated automatically. J Spinal Disord. 520 Lake Cook Road, Suite 350, 5:10-6. Mai Nielsen S,Tarp S,Christensen R, Bliddal H,Klokker L, Henriksen M.The risk associated with spinal manipulation: an overview of reviews. This option relieves symptoms associated with degenerative disc disease and maintains range of motion. 1992 Jun. [22]. The anterior and posterior surfaces are flattened and of equal depth; the former is placed on a lower level than the latter, and its inferior border is prolonged downward, so as to overlap the upper and forepart of the vertebra below. The posterior part, the true transverse process, springs from the vertebral arch behind the foramen, and is directed forward and laterally; it ends in a flattened vertical tubercle, the posterior tubercle. [Medline]. Unlike the other parts of the spine, the cervical spine has transverse foramina in each vertebra for the vertebral arteries that supply blood to the brain. The anastomotic arcade also receives tributaries from the ascending pharyngeal arteries that join the arcade after passing through the occipital condyle. The space between the vertebrae is filled using a small piece of bone or device through spinal fusion. No too much importance should be placed on abnormalities found on this assesment, only relevant if they are verified by radiology. This space, called the spinal canal, is the area through which the spinal cord and nerve bundles pass. Note uniquely shaped atlas and axis (C1 and C2). Postoperatively, the neurosurgeon may elect to obtain x-rays of the spine to assess alignment, status of the instrumentation and fusion and generally monitor levels of the spine adjacent to the surgery. The top 7 vertebrae that form the neck are called the cervical spine and are labeled C1-C7. 1974 Dec. 56(8):1683-91. Mary L Windle, PharmD Adjunct Associate Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Nothing to disclose. [9]. Introduction to Cervical Vertebrae Anatomy: Inferior to the atlas bone (C1) and axis bone (C2) are the five remaining cervical vertebrae (C3-C7). They serve as force dissipators, transmitting compressive loads throughout a range of motion. Manhasset, N.Y. Articulations include disk-vertebral body articulations, uncovertebral joints, and zygapophyseal (facet) joints. All Rights Reserved, background-image - a woman looking at a screen.

Approximately 50% of flexion extension of the neck happens between the occiput and C1; 50% of the rotation of the neck happens between C1 and C2. 2017; 6: 64. The movement rotating the head left and right happens almost entirely at the joint between the atlas and the axis, the atlanto-axial joint. Elsevier Churchill Livingstone, 2005. The transverse ligament is the most important ligament for preventing abnormal anterior translation. This may be associated with the typical complaints of patients with whiplash injuries (eg, headache, neck pain, and dizziness). The cervical vertebrae, discussed on the next page, play a key role in maintaining the neck’s functions and facilitating its movements. Each has a vertebral body that is concave on its superior surface and convex on its inferior surface (see the image below). Bogduk N, Twomey L. Clinical Anatomy of the Lumbar Spine. With so many critical nerves, blood vessels, and joints in such a relatively small space, the cervical spine is one of the body’s most complicated regions. 371-83. The second cervical vertebrae (C2) is known as the axis. 19(5):495-501. The centrum of the proatlas sclerotome becomes the apical cap of the dens and the apical ligaments. What Is a Cervical Spine CT Scan?. 9(6):573-85. These vertebrae share many anatomical characteristics. If the operation is more extensive, it may require a slanted or longer incision. Superior view of a cervical vertebra - test yourself. Herniated discs or bone spurs may cause a narrowing of the spinal canal or the small openings through which spinal nerve roots exit. 2.3. The cervical spine in your neck is made up of seven bones called vertebrae, which are separated by discs filled with a cushioning gel-like substance. Both ligaments are found throughout the entire length of the spine; however, the ALL adheres more closely to the disks than the PLL does, and it is not well developed in the cervical spine. Thomas R Gest, PhD Professor of Anatomy, University of Houston College of Medicine These discs allow the spine to move freely and act as shock absorbers during activity. The body is deeper in front than behind, and prolonged downward anteriorly so as to overlap the upper and front part of the third vertebra. The cervical spine is reached through a small incision in the anterior (front) of the neck. The upper back, or thoracic spine, has 12 vertebrae, labeled T1-T12. Spine (Phila Pa 1976).
