Developmental anomalies in the cervical spine, such as occipitalization or other segmentation anomalies, are common incidental findings but also may be symptomatic and associated with clinically important anatomic changes such as atlantoaxial instability and basilar invagination. 1952;59:713-714, with permission.) Inpatient records over a 3-year period were reviewed. If the address matches an existing account you will receive an email with instructions to reset your password. One hundred ten patients with normal spine plain films underwent dynamic fluoroscopy with flexion and extension views of the cervical spine. ); and Department of Radiology, Keck School of Medicine, University of Southern California, Los Angeles, Calif (G.R.M., W.N.G. On the scout view the abnormal relationship between skull and cervical spine is seen. Lateral c-spine x-ray description. Occipitalization and basilar invagination can also be misdiagnosed owing to the simulation of this appearance when the head is in the lateral flexion position at imaging. Dynamic F/E X-rays may be taken to look for spinal instability. Figure a. Anteroposterior radiograph (a) and oblique illustration (b) of the lower cervical spine show degenerative hypertrophy of the facets (black arrow) and uncovertebral joint (white arrow), leading to neuroforaminal stenosis. © 2020 Radiological Society of North America, Ossification of the posterior longitudinal ligament: a review of The cervical spine is host to a variety of normal and pathologic soft-tissue calcifications that may be discovered at routine radiography. literature, Multidetector CT of blunt cervical spine trauma in Summary Due to the unique anatomy of the cervical spine in paediatric patients, radiographic interpretation can be difficult. Normal cervical spine in infants and children. Low dose X-ray fluoroscopy allows time-continuous screening of cervical spine during patient’s spontaneous motion. tendinitis of the longus colli—case reports, Open in Image Anterior cervical fusion is the most common surgical intervention and has been proven effecti~e.~.~~ Nonsurgical treatment is indicated when cervical clinical adults, CT and MR imaging of odontoid abnormalities: a pictorial No patients undergoing dynamic fluoroscopy were subsequently found to have missed cervical spine injury. review, Case reports about an overlooked cause of neck pain: calcific Superimposition of overlying anatomy in the upper cervical spine may also mimic pathologic conditions, such as Mach effect mimicking a dens fracture, or may obscure pathologic conditions, as when the head is too extended or flexed on an open-mouth view. Static cervical spine radiography revealed abnormal findings in 23 (9%) of 247 patients. AP cervical spine x-ray appearances. Author information: (1)Graduate Department, Tianjin University of Traditional Chinese Medicine, Tianjin, China. We performed a prospective study of a cervical spine clearance algorithm incorporating dynamic fluoroscopy with flexion/extension views. Presented as an education exhibit at the 2017 RSNA Annual Meeting. Radiology Assistant 2.0 app StartRadiology iPad version of the Radiology Assistant iPhone iPhone application Shoulder MR - Instability Robin Smithuis and Henk Jan van der Woude Radiology department of the Rijnland hospital The average Glasgow Coma Score was 9.2 and the average revised Trauma Score was 9.5. To establish a dynamic three‐dimensional (3D) model of upper cervical spine instability and to analyze its biomechanical characteristics. the detector is placed portrait, parallel to the long axis of the cervical spine on the patients left side. ). The average Glasgow Coma Score was 9.2 and the average revised Trauma Score was 9.5. Normal and variant calcifications include thyroid and tracheal cartilages, nuchal sesamoids, and the stylohyoid ligaments. 1944;25(5-6):593-609. Metastatic disease is also frequently encountered, and Pancoast tumors may be detected incidentally on cervical spine radiographs. Finally, infection involving the cervical region, with extension to the spine and subsequent spondylodiscitis, manifests with disk height loss and eventual destruction of the vertebral endplates. the patient will have the neck in the extended (chin up) or flexion (chin down) position depending on the projection. the patient is erect, left side against the upright detector. On the images on the left notice the abnormal relationships of the basion, opisthion and the tip of the dens and the posterior arch of the atlas. One hundred ten patients with normal spine plain films underwent dynamic fluoroscopy with flexion and extension views of the cervical spine. Extension-Flexion (dynamic) X-ray studies of all 38 patients were analyzed. Static flexion/extension views are unsafe, as the obtunded patient has no protective reflexes and cannot complain of pain during the exam. Cle aring the cervical spine in a multiply injured trauma patient is a dilemma because clinical examination for ligamentous instability cannot be performed, and the standard cervical spine series can miss isolated ligamentous injury. Neoplasms are frequent in the cervical spine, and the cervical spine is the most common spinal location for osteochondroma and chordoma. https://doi.org/10.1016/S0149-7944(00)00441-4. Dynamic 4DCT can be used to detect and confirm subtle cervical spinal instability (or lack thereof) with relative ease in various cervical spinal pathologies such as rheumatoid arthritis, cervical … Instability is typically considered when there is a measurement greater than 2.5–3.5 mm of combined intersegmental translation motion of the lower cervical vertebrae between flexion and extension. Twenty-one consecutive patients with atlantoaxial subluxation due to rheumatoid arthritis planned for atlantoaxial fusion were included. Cervical magnetic resonance imaging abnormalities not ... ... Sign in The online presentation reviews these entities and more, with numerous case examples and detailed medical illustrations to clarify concepts. B: Coronal reconstruction of the C-spine demonstrates all of the synchondroses outlined in figure (A)(C) (D), body (B)(N) 2004 Jul;1(1):39-42. Dynamic fluoroscopy may be useful in the detection of otherwise occult injuries. Patient demographic data, results of cervical spine films and fluoroscopic exams, interventions based on positive results, and missed injuries were recorded. Degenerative disease in the cervical spine, although nearly ubiquitous with age, is commonly symptomatic owing to the neuroforamina being bordered by the uncovertebral joints anteriorly and facets posteriorly, both of which are well appreciated radiographically (Figure). Pathologic calcifications are diverse and include atherosclerotic calcifications, lymph node calcifications, salivary stones, glandular parenchymal calcifications, and calcified thyroid and parathyroid lesions. the utilisation of a particular radiographic imaging procedure to detect cervical spine instability in trauma patients. Discussion In 1980, Wales et al. Systematic approach to cervical spine x-ray interpretation. In addition, a variety of rare primary osseous neoplasms may manifest in the cervical spine, such as aneurysmal bone cyst, osteoblastoma, osteoid osteoma, and brown tumor. Cervical spine anatomy - X-ray appearances. In seven (30%) of 23 patients, cervical spine radiography revealed congenital abnormalities and dynamic radiography was performed to assess Nine patients had evidence of cervical instability on exam. The full digital presentation is available online. In addition, posterior disk-osteophyte complexes that narrow the canal are frequently identifiable at radiography. This type of X-ray is called a dynamic radiograph. Normal c-spine x-ray. Comment on J Neurosurg Spine. It tends to be more common with longstanding disease and in those with multi-articular Cervical instability. Aota Y, Kumano K, Hirabayashi S. Postfusion instability at the adjacent segments after rigid pedicle screw Familiarity with the developmental anatomy and normal variants is critical to prevent the wrong diagnosis. In this overview we will discuss the most common cervical spine Copyright © 2020 Elsevier B.V. or its licensors or contributors. The instability of the spine (not only the cervical zone) is divided into several species, depending on the negative factor that caused the pathological condition: posttraumatic appearance. Methods A 3D geometrical model was established after CT scanning of the upper cervical spine specimen. Instability of the vertebrae is formed as a result of a previous trauma (dislocations, subluxations, vertebral fractures); From the Department of Radiology, Palmer College of Chiropractic, West Campus, 90 E Tasman Dr, San Jose, CA 95134 (M.R.S. This results in a need for prolonged spinal immobilization and its attendant complications. Patients with cervical spondylotic myelopathy with severe disc degeneration (n = 42) were more likely than patients without (n = 75) to have segmental instability. One third of injuries occur at the level of C2, and one half of injuries occur at the level of C6 or C7. Spinal cord compression by static and dynamic factors should be treated by multilevel anterior decompression and fusion or … ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Cervical spine instability: clearance using dynamic fluoroscopy. One patient with positive findings had cervical immobilization with hard collar continued, a second had halo placement, and a third underwent spinal fusion for atlanto-occipital disassociation. The aim of this study was to evaluate the relationship between MCs and cervical segmental instability, cervical curvature and range of motion (ROM) in the cervical spine. Pitfalls in Clinical Imaging 21Keywords: cervical spine, CT, fracture, trauma 1Both authors: Department of Radiology, New York University Langone Medical Center/ Bellevue Hospital, 560 First Ave, HG … One such example is in rheumatoid arthritis patients in preoperative anaesthetic work-ups. Given the significant medical and legal ramifications of missed cervical spine injury and the benefits of early removal of cervical collars, more widespread use of dynamic fluoroscopy of the cervical spine is warranted. Instability is typically considered when there is a measurement greater than 2.5–3.5 mm of combined intersegmental translation motion of the lower cervical vertebrae between flexion and extension. The axial CT-image demonstrates blood surrounding the brainstem. Figure b. Anteroposterior radiograph (a) and oblique illustration (b) of the lower cervical spine show degenerative hypertrophy of the facets (black arrow) and uncovertebral joint (white arrow), leading to neuroforaminal stenosis. review, Imaging the spine in arthritis: a pictorial Viewer, The Art of Interpreting Cervical Spine Radiographs, Imaging of the Spine in the Inflammatory Arthritis: Plain Radiograph, CT and MRI, Spectrum of Imaging Findings in Hyperextension Injuries of the Neck, Multimodality Imaging Approach to Craniovertebral Junction (CVJ) Anomalies: A Road Map for Surgeons Â, Oh, My Aching Back! As a result, no benchmark for cervical spine clearance exists. The intraobserver correlation coefficient ranged from 0.77 to 0.90 mm. Most cervical spine fractures occur predominantly at two levels. Copyright © 2001 Elsevier Science Inc. All rights reserved. To compare CR with CT (static and dynamic) to evaluate upper spine instability and to determine if CT in flexion adds value compared to MR imaging in neutral position to assess compression of the subarachnoid space and of the spinal cord. Multidetector CT of blunt cervical spine trauma in adults . Knutsson F. The instability associated with disk degeneration in the lumbar spine. This allows for a better idea of how the spine looks in a functional position. Interpreting cervical spine radiographs is routine work for most radiologists. The average difference between neutral standing radiograph and supine MRI was 3.77 mm, with dynamic instability detected in 60.7% of patients. The natural inaccessibility of the spine, its complex anatomy, and the small range of motion only permit concise measurement in vivo. The interobserver correlation coefficient ranged from 0.79 to 0.86 mm. Cervical involvement can occur in over 80% [2]. Crossref , Medline , Google Scholar Dreizin D , Letzing M , Sliker CW et al. Nine patients had evidence of cervical instability on exam. Differential considerations and potential pitfalls are also discussed. (From Bailey DK. Radiology department of the Alrijne Hospital in Leiderdorp, the Netherlands This is an updated version largely based on the recommendations of the combined task forces of the North American Spine Society, the American Society With our protocol, 3 patients had significant cervical instability that would have been missed without dynamic fluoroscopy. This dynamic assessment is also important to assess potential instability associated with inflammatory arthritis. Patient position. Conclusion: The 3D dynamic finite-element model of the upper cervical spine can be used to analyze and summarize the relationship between the change of ligament stress and the degree of instability in cervical instability. cervical spine instability presents with severe neurolog- ical involvement. Clinical instability of the cervical spine is defined as the inability of the spine under physiological loads to maintain its normal pattern of displacement so that there is no neurological damage or irritation, no development of deformity, and no incapacitating pain. Radiology. spine abnormalities. Despite their seemingly simple nature, cervical spine radiographs can be difficult to interpret owing to abundant information, complex anatomy, and projectional variation.

All authors have disclosed no relevant relationships. Rabb CH. [1] proposed a clinical– radiologic algorithm for the evaluation of trau-matic cervical spine injuries. This article will focus on the problem of a "world in motion," and other vision problems and how one explanation as to why treatments and therapies have not helped you is because you have unidentified cervical neck / spine instability. However, angular instability is less well defined and understood, but a measurement of 11 degrees or greater of intersegmental angular difference when compared to that of the adjacent levels is concerning and may be associated with facet subluxation or dislocation.

Flexion–extension radiographs were recommended for the flexion/extension radiographs can be used in the assessment of cervical spine stability in situations where a single lateral view may be insufficient. Asian Spine J 2011; 5 ( 4 ): 267 – 276 . 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. This patient would have been at significant risk of cord injury if intubation was performed without Wang XD(1), Feng MS(2), Hu YC(3). Acta Radiol. This case emphasizes the importance of assessing for cervical instability in rheumatoid arthritis patients prior to any planned intubation. This dynamic assessment is also important to assess potential instability associated with inflammatory arthritis. Enter your email address below and we will send you the reset instructions. with delayed cervical spine instability. Establishment and Finite Element Analysis of a Three-dimensional Dynamic Model of Upper Cervical Spine Instability. Six of these were deemed stable by the orthopedic or neurosurgical spine consultants, and these patients had their hard collars removed. Rheumatoid arthritis involving the cervical spine was first described by Garrod in 1890 [1].
