Check for errors and try again. Early articles advocated the use of flexion—extension radiographs in the setting of trauma [1,2,3].This literature suggested that, in several cases, flexion—extension radiographs would have revealed severe ligamentous injuries not shown on static cervical spine radiographs. When comparing the neutral position and extension, the mean change in interspinous distance varied from 1.2 to 2.2 mm (SD 1.7 to 1.9). Flexion/extension views are absolutely contraindicated in documented unstable injuries. If you can’t get a flexion-extension X-ray, the proper type of exam should suffice. 7 : Systematic approach of the lateral view - 3 contour lines. Lewis LM, Docherty M, Ruoff BE, Fortney JP, Keltner RA Jr, Britton P. Flexion-extension views in the evaluation of cervical-spine injuries. • Flexion and extension (lateral) views can be helpful in assessing spinal mobility and stability • Limitations • Problems with both specificity and sensitivity exist ... • The accuracy of CT imaging of the cervical spine ranges from 72-91% in the diagnosis of disc herniation. Trauma McGill Notes. Lewis LM, Docherty M, Ruoff BE, Fortney JP, Keltner RA Jr, Britton P. Flexion-extension views in the evaluation of cervical-spine injuries. Back of body of C2 down, and back of body of C7 up, measure where the 2 lines intersect. This may be in the trauma series of radiographs that typically include the lateral cervical spine, chest and pelvis in the setting of acute injury or with flexion–extension views performed as part of planned pre-anaesthetic care. Objectives: To investigate the usefulness of flexion and extension radiographs of the cervical spine as a screening tool for the acute evaluation of ligamentous injury in cases of awake blunt trauma in patients with a negative cervical computed tomography scan. • AP - CR angled 15 degrees cephalic. Again, Flexion-extension views should not be obtained until the entire cervical spine is otherwise cleared radiographically. ... take flexion/extension views, potential to be unstable, ... massive fusion of cervical spine Type II: fusion of 1 or 2 vertebrate Flexion and extension cervical spine radiography can be self defeating in the acute setting. On frontal view of cervical spine, at level of the locked facet (C5), the spinous process is displaced towards the right (black arrow), out of alignment with those below it (white arrows). It should not be used in a trauma setting. Flexion/extension views are absolutely contraindicated in documented unstable injuries. References: Flanders A. Radiology Assistant - Spine - Cervical injury. MATERIALS AND METHODS: Sixty-two patients with cervical degenerative disease were evaluated with regard to the dynamic changes of canal stenosis at flexion-extension MR imaging. Search. Setting: Level I trauma center. ... focal or asymmetrical posterocentral, posterolateral, or lateral extension of disk material into spinal canal and/or neural foramen. Results of the flexion-extension views had minimal effects on clinical decision making. This is called a flexion-extension x-ray. CT imaging techniques for describing motions of the cervicothoracic junction and cervical spine during flexion, extension, and cervical traction. Start studying Cervical Spine Radiology. flexion/extension radiographs can be used in the assessment of cervical spine stability in situations where a single lateral view may be insufficient.

The pain from this trauma prevents the patients from flexing and extending … Normal anatomy, common fractures, and management are presented. In this case series, the sensitivity and specificity, respectively, of both FECTR and CT were 80% and 98.6% for all radiographic abnormalities. forming flexion-extension magnetic resonance imaging (MRI) under sedation/anesthesia in these children. Flexion and extension views ( Figure 3-18 ) are sometimes obtained to assess for ligamentous instability—the evidence for these views is discussed in detail later. Study design: Retrospective study of consecutive patient series. In such cases, magnetic resonance imaging is required to definitively exclude pathological injury. There is no associated Hangman's fracture. Three pathologic conditions were readily demonstrated: anterior atlantoaxial subluxation (n = 6), atlantoaxial impaction (n = 6), and subaxial su … Put in your zip code, or city and state to see what’s closest. Cervical rheumatoid arthritis: value of flexion and extension views in imaging The magnetic resonance (MR) imaging findings in the cervical spines of eight patients with long-standing polyarticular rheumatoid arthritis were reviewed. Top. Odontoid. Figure 3-17 Swimmer’s view x-ray of the cervical spine. Conclusion: Adequate flexion extension films are difficult to obtain and are minimally helpful for clearance of the cervical spine in awake and alert trauma patients. The lumbar spine flexion and extension views images the lumbar spine which consists of five vertebrae. Flexion and extension views can be helpful in assessing spinal mobility and stability in these patients. In flexion, the odontoid process may compress the upper cervical cord, which is clinically expressed as Lhermitte’s sign, and if sufficiently forceful, can cause death. Houben PH, der van Weijden T, Sijbrandij J, Grol RP, Winkens RA. Interpreting cervical spine radiographs is routine work for most radiologists. Publicationdate November 24, 2008 This review is based on a presentation given by Adam Flanders and adapted for the Radiology Assistant by Robin Smithuis. What if no fracture is seen on initial films and pain is present? Start studying Cervical Spine Radiology. Far superior visualization of the cervicothoracic junction was achieved compared with flexion-extension cervical spine radiographs. (A) Cervical spine radiographs (flexion/extension views) in a pJIA of 24 years with anterior erosion of the odontoid process (arrow) and aAAS (black line) with an atlantodental interval equal to 9.3 mm. As there is very little literature on the proper evaluation of these radiographic views, we reviewed 150 consecutive cases from our Emergency Department to define patterns of flexion. Normal upright radiographic studies, above, were obtained on … AP C spine. specialized projections of the cervical spine often requested to assess for spinal stability. Dynamic (flexion-extension) views of the cervical spine may aid in the identification of such injury. Simon S(1), Davis M, Odhner D, Udupa J, Winkelstein B. Association of injury mechanism with the risk of cervical spine fractures. The lateral radiograph forms a frequently utilized and readily available initial imaging approach.

Reasons for ordering spinal x-ray investigations: how they influence general practitioners' management. Note: in the absence of CT 5 views of the C-spine should be performed: AP, lateral, obliques and odontoid 5. The accuracy of CT imaging of the cervical spine ranges from 72-91% in the diagnosis of disc herniation. 52 (10): 1266-7. 1. Selection criteria for neutral-position MR imaging, such as cervical curvature, canal space, degenerative stage, intramedullary high signal intensity on T2-weighted images, and resting instability, were evaluated for their ability to predict functional cord impingement at flexion-extension MR imaging (Fisher exact test, logistic regression analysis). The patient should perform the flexion and extension voluntarily. CJEM. 13 Flexion views in this case showed no measurable worsening of the spondylolisthesis and it appeared to resolve in extension. Pubmed citation. 6: Plain x-ray films- others views: A-"Swimmer" view, B- Flexion view, C- Extension view. ), but care must be taken depending on the degree of suspicion of instability. Lateral projection flexion and extension radiographs of the cervical spine are stress views. “Cervical spine trauma is common following rapid acceleration-decelerations during low-impact motor vehicle collisions due to the wide range of motion of the cervical spine and relative absence of supporting structures.” “Plain film evaluation, including lateral flexion and extension views, is the The Canadian C-Spine Rule. The magnetic resonance (MR) imaging findings in the cervical spines of eight patients with long-standing polyarticular rheumatoid arthritis were reviewed. Plain Films. Lateral cervical neutral, extension and flexion. A retrospective descriptive study was carried out between July 1, 1990, and June 30, 1994, in an academic emergency department averaging 60, 000 patient visits (of which 20% are pediatric) per year. Do a Swimmers Lateral if necessary to visualize C7 – T1. Problems with both specificity and sensitivity exist. The cervical spine series is a set of radiographs taken to investigate the bony structures of the cervical spine, albeit commonly replaced by the CT, the cervical spine series is an essential trauma radiograph for all radiographers to understand. Pre-vertebral soft tissue swelling is also described. They are necessary to evaluate unstable ligamentous injury, which may not be apparent on neutral unstressed films. In order to replicate the conditions under which there is too much movement in the spine vertebrae, an x-ray can be taken when the patient moves. 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. Imaging of the Cervical Spine > Technique > Plain Films. (2017) ISBN: 9780323399661, 3. Magnetic resonance imaging of the cervical spine with and without contrast media is the preferred imaging modality. Despite their seemingly simple nature, cervical spine radiographs can be difficult to interpret owing to abundant information, complex anatomy, and projectional variation. ... 72050 x-ray, spine cervical 4+ views 72052 x-ray spine cervical complete, ... 72148 MRI MR Lumbar without contrast with Flexion & Extension • Back pain/lower extremity radicular symptoms, especially when position dependent An adequate spine series includes three views: a true lateral view (which must include all seven cervical vertebrae as well as the C7-T1 junction), an AP view, and an open-mouth odontoid view.
