During functional movements flexion-extension, lateral flexion and rotational movements are performed in harmony. Does the Veteran report flare-ups of the cervical spine? Bontrager's Textbook of Radiographic Positioning and Related Anatomy. Flexion, extension, rotation, lateral flexion, and circumduction are the basic movements of the cervical region. The Art of Interpreting Cervical Spine Radiographs. â¢Lateral flexion: Vertebral body needs to glide away from the direction of lateral flexion. part of a secondary survey or under the guidance of an authorized physicianÂ, >2.5-3.5 mm of intersegmental translation (a summation of the displacement observed between vertebra tracing the posterior line on both the flexion and extension view) is considered a marker of instability, 1. Assists with contralateral rotation of the cervical spine when acting unilaterally 2. Ten fresh human cadaver specimens occiput-C3 were studied in a complete unconstrained and three-dimensional manner, first intact and then after sequential cutting of the left and right alar ligaments. Note the remarkable axial rotation motioin coupled with the lateral bending of the cervical spine. The facet toward the lateral flexion closes and the opposite facet opens. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. This 3D medical animation depicts the anatomy of the cervical spine in a lateral flexion or tilting motion. {"url":"/signup-modal-props.json?lang=us\u0026email="}, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":58732,"mcqUrl":"https://radiopaedia.org/articles/cervical-spine-flexion-and-extension-views/questions/1602?lang=us"}. 2C. PMID: 21963828 Cervical spine lateral view is a lateral projection of the cervical spine. Unable to process the form. Finding of range of cervical spine left lateral flexion (366391002); Range of cervical spine left lateral flexion - finding (366391002) Recent clinical studies. As technology advances, computed tomography (CT) has replaced this projection, yet there remain many institutions (especially in rural areas) where CT is not readily available. It consists of seven distinct vertebrae, two of which are given unique names: The first cervical vertebrae (C1) is known as the atlas. Indications These views are specialized projections often requested to assess for spinal stability. Cervical spine lateral view is a lateral projection of the cervical spine. The segmental movements have six degrees of freedom relative to a Cartesian coordinate system and are coupled between lateral flexion, rotation, and flexion or extension, depending on the segmental levels during normal global motion. Note: tests should only be performed by a properly trained health care practitioner. Sitting, with thoracic & lumbar spine well supported by the back of the ⦠Since the collar supports a portion of head weight, the cervical spine is partially unloaded. (2017). Range of movement (ROM) ï¶50% of flexion extension happens in the upper cervical ï¶50% of rotation happens in C1-2 level ï¶Lateral flexion mostly on the middle part of the cervical spine White & Panjabi Clinical Biomechanics of the Spine 2ndEdition Flexion -extension Lateral flexion Rotation John Lampignano, Leslie E. Kendrick. Most lateral flexion occurs between the occiput and C1 and between C1 and C2. This movement between the atlas and occipital bone is often referred to as the "yes joint", owing to its nature ⦠The kinesiologic finding was the fo ⦠This is consistent with instability and probable ligamentous injury; the patient was treated with surgical stabilization of the C1-C2 interspace. White AA, Johnson RM, Panjabi MM, Southwick WO. ⢠Cervical spine laterally flexed and opposite shoulder is depressed ⢠Positive if radiating/âburningâ pain in upper extremity âIf traction injury, symptoms noted on side of depressed shoulder âIf compression injury, symptoms noted in direction of lateral flexion It also acts in transmitting forces and load through the cervical spine. Lateral flexion is not a significant movement at the atlantooccipital joint, in terms of range of motion. Figure 12. Five brachialgia patients were found to have a hypomobile first rib on the painful side in a cineradiographic study. ADVERTISEMENT: Supporters see fewer/no ads. The biomechanics of the cervical region are among the most complex motions within the human spine. The cervical spine flexion and extension views demonstrate the seven vertebrae of the cervical spine when the patient is in a lateral position. {"url":"/signup-modal-props.json?lang=us\u0026email="}, systematic radiographic technical evaluation, humerus axial (bicipital groove) view (Fisk view), occipitomental 30º view (Titterington view), paranasal sinuses and facial bones radiography, transoral parietocanthal view (open mouth Waters view), AP closed mouth odontoid view (Fuchs view), the patient is supine or erect, depending on trauma or follow up, the detector is placed portrait, running parallel to the long axis of the cervical spine on the patients left the side, inform the patient that the image will be taken on suspended expiration, 2.5 cm above the jugular notch at the level of C4, there should be a clear visualization of C1 to T1 (T1 minimum), the vertebral bodies are superimposed laterally, the articular pillars and zygapophyseal joints are superimposed, this projection may require inferior traction of the arms to better visualize T1, this should only be performed by a qualified individual. (2019) RadioGraphics. limit flexion, extension, lateral flexion and rotation of the head and cervical spine, and to partially relieve gravitational stress by weight transfer. For example : In left lateral flexion of the neck and cervical spine, each segment of the lower cervical spine is as in left rotation, with lateral flexion, rotation, and slight extension. Unable to process the form. As technology advances, computed tomography (CT) has replaced this projection, yet there remain many institutions (especially in rural areas) where CT is not readily available. The average number of degrees of motion that the cervical (cervicocranial â head and neck) spine can move is: Flexion â 50 degrees; Extension â 80 degrees; Right lateral flexion â 45 degrees; Left lateral flexion â 45 degrees points to keep in mind whilst traction is being applied: full expiration is best for optimal inferior displacement of the shoulders to visualize T1, clear communication between yourself and the one performing traction is a must, ensure they are clear when traction is being applied as to avoid motion artifact, ensure individual applying traction is in a lead gown, 1. They limit lateral flexion to the opposite side of the body from where they are located (contralateral lateral flexion). Furthermore, lateral flexion in the upper cervical spine is both a coupled movement and a double-joint movement. The cervical spine can move in all three cardinal planes (sagittal, frontal, and transverse). Scientific evidence for the 49° of cervical lateral flexion motion range. The more superficial flexor muscles of the cervical spine include sternocleidomastoid (SCM) and anterior scalenes (AS): Sternocleidomastoid functions bilaterally to create neck flexion and unilaterally to create ipsilateral lateral flexion and contralateral rotation. 2. Ligaments of the spine. Note, such functional views should not be performed on trauma patients without the strict instructions of a qualified clinician. Biomechanical analysis of clinical stability in the cervical spine. Both rotation and lateral flexion involve slight flexion of the atlanto - occipital joint to compensate for extension of the lower cervical spine. Movements of the head on the neck are generally confined to the occiput-atlas-axis complex and can be described separately from movements of the neck on the trunk. (A) Right lateral view of a sagittal plane cross section through the spine. 45-57 degrees. Bontrager's Textbook of Radiographic Positioning and Related Anatomy. Lateral flexion. (2017). It also helps to demonstrate any adjacent soft tissue structure, osteoarthritis and spondylosis. There are also small amounts of flexion, extension and lateral flexion.

The purpose of this in vitro experimental study was to determine the role of alar ligaments in providing flexion, extension, and lateral bending stability to the upper cervical spine. This chapter will review global ranges of motion, segmental motion, coupled motion⦠Caillet (1981) stated ⦠Relationship between active cervical range of motion and flexion-relaxation ratio in asymptomatic computer workers. The lateral flexion cervical spine radiograph (right) shows an increase in the predental distance (black, double-headed arrow) to greater than 5 mm. In the setting of cervical spine trauma, CT has all but supplanted traditional radiographic assessment (sensitivity is about 98% for CT versus about 50% for radiography), yet it remains common to obtain radiographs in less emergent cases and for the dynamic assessment of stability with flexion and extension radiographs. The SCM is innervated by a spinal root of the accessory nerve (Cleland, 2005). The axial rotation and simultaneous lateral flexion of the cervical spine is kinesiologically related to the movements of the upper thoracic spine. Lateral Flexion (Abduction): Definition: Bending the cervical spine laterally (to the left or right side), away from the sagittal plane (midline), by moving head and neck to the left or right. The cervical spine is the most superior portion of the vertebral column, lying between the cranium and the thoracic vertebrae.. Matthew R. Skalski, George R. Matcuk, Jr, Wende N. Gibbs. systematic radiographic technical evaluation, humerus axial (bicipital groove) view (Fisk view), occipitomental 30º view (Titterington view), paranasal sinuses and facial bones radiography, transoral parietocanthal view (open mouth Waters view), AP closed mouth odontoid view (Fuchs view), the patient is erect, left side against the upright detectorÂ, the detector is placed portrait, parallel to the long axis of the cervical spine on the patients left sideÂ, the patient will have the neck in the extended (chin up) or flexion (chin down) position depending on the projection, 2.5 cm above the jugular notch at the level of C4, there should be clear visualization of C7 to T1, the image is labeled as 'flexion' or 'extension' Â, flexion images should demonstrate well separated spinous processÂ, extension images should demonstrate crowding of the spinous process, demonstrate to the patient what flexion and extension is before performingÂ, ensure the patient is aware when the examination is over as to avoid extended periods of time in that positionÂ, patients who feel unstable on their feet can sit in a chair for this examinationÂ, ensure this radiographic series is safe to perform, i.e. Side-by-side anterior view of the cervical spine motion in the frontal plane â from the neutral spine to the right and to the left (C0-C7 one side lateral bending 49°). This projection helps to visualize pathology involving the entire cervical spine orthogonal to the AP view and is often performed in the trauma setting. It is the joint that provides a large proportion of axial rotation of the head i.e. Many of these ligaments also act to limit rotation of the cervical spine to one side or the other. 3-6 Lateral flexion assessed with an inclinometer. FIG. These views are specialized projections often requested to assess for spinal stability. (1975) Clinical orthopaedics and related research. Etiology. (âCervical spine rotation and lateral flexion combined motion in the examination of the thoracic outletâ). However, the cervical spine is comparatively mobile, and some component of this movement is due to flexion and extension of the vertebral column itself. In fact, cadaveric studies limit lateral flexion of the upper cervical spine to approximately 5-8° on either side. Lateral flexion of the cervical spine when acting unilaterally Secondary Actions of the Scalenus Medius: 1. John Lampignano, Leslie E. Kendrick. Manual technique in supine and sitting. The AA joint contributes 50% of overall cervical rotation. The movements of the cervical spine show significant differences from thoracic and lumbar regions. 3. References: Lindgren KA, Leino E, Hakola M, Hamberg J. The clinical significance of these structures is the high tendency of developing degenerative changes that may impinge vertebral artery, cervical nerve roots or anterior part of spinal cord.They allow for flexion and extension and limit lateral flexion in the cervical spine.They prevent posterior linear translation movements of the vertebral bodies,Important in providing stability and guiding the motion of the cervical spine. While fulfilling these functions, they also protect the spinal cord, that passes through vertebral canal. Check for errors and try again. Check for errors and try again. ; The second cervical vertebrae (C2) is known as the axis. The cervical spine flexion and extension views demonstrate the seven vertebrae of the cervical spine when the patient is in a lateral position. Lateral flexion of the cervical spine is normally approximately 20 to 45 degrees to the right and left.
