Abstract
Cervical facet injuries, though less common than other spinal injuries, represent a subset of subaxial cervical spine injuries and can present significant challenges in terms of diagnosis, management, and outcomes. A major concern with cervical facet fracture is identifying instability patterns that may necessitate surgical stabilization. Particularly in cases of cervical facet fracture dislocations, there remains controversy regarding requirements for closed reduction, timing, surgical approach, need for preoperative MRI, and method of fixation. This review article aims to provide a thorough understanding of the etiology, clinical presentation, diagnostic techniques, treatment options, and prognostic factors associated with cervical facet fractures.

Abstract
BACKGROUND DATA Computed Tomography (CT) is the gold standard for cervical spine (c-spine) evaluation. Magnetic resonance imaging (MRI) emerges due to its increasing availability and the lack of radiation exposure. However, MRI is costly and time-consuming, questioning its role in the emergency department (ED). This study investigates the added the value of an additional MRI for patients presenting with a c-spine injury in the ED. METHODS We conducted a retrospective monocenter cohort study that included all patients with neck trauma presenting in the ED, who received imaging based on the NEXUS criteria. Spine surgeons performed a full-case review to classify each case into "c-spine injured" and "c-spine uninjured". Injuries were classified according to the AO Spine classification. We assessed patients with a c-spine injury detected by CT, who received a subsequent MRI. In this subset, injuries were classified separately in both imaging modalities. We monitored the treatment changes after the additional MRI to evaluate characteristics of this cohort and the impact of the AO Spine Neurology/Modifier modifiers. RESULTS We identified 4496 subjects, 2321 were eligible for inclusion and 186 were diagnosed with c-spine injuries in the retrospective case review. Fifty-six patients with a c-spine injury initially identified through CT received an additional MRI. The additional MRI significantly extended (geometric mean ratio 1.32, p < 0.001) the duration of the patients' stay in the ED. Of this cohort, 25% had a change in treatment strategy and among the patients with neurological symptoms (AON ≥ 1), 45.8% experienced a change in treatment. Patients that were N-positive, had a 12.4 (95% CI 2.7-90.7, p < 0.01) times higher odds of a treatment change after an additional MRI than neurologically intact patients. CONCLUSION AND RELEVANCE Our study suggests that patients with a c-spine injury and neurological symptoms benefit from an additional MRI. In neurologically intact patients, an additional MRI retains value only when carefully evaluated on a case-by-case basis.

Rethinking cervical spine clearance in obtunded trauma patients: An updated systematic review and meta-analysis. Injury 2024; 55:111308. [PMID: 38266326 DOI: 10.1016/j.injury.2023.111308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/23/2023] [Accepted: 12/29/2023] [Indexed: 01/26/2024]
Abstract
BACKGROUND Cervical spine injuries (CSI) are often challenging to diagnose in obtunded adult patients with blunt trauma and the optimal imaging modality remains uncertain. This study systematically synthesized the last decade of evidence to determine the type of imaging required to clear the c-spine in obtunded patients with blunt trauma. METHODS A systematic review with meta-analysis was conducted and reported using PRISMA 2020 guidelines. The protocol was registered on June 22, 2022 (PROSPERO CRD42022341386). MEDLINE (Ovid), EMBASE, and Cochrane Library were searched for studies published between January 1, 2012, and October 17, 2023. Studies comparing CT alone to CT combined with MRI for c-spine clearance were included. Two independent reviewers screened articles for eligibility in duplicate. Meta-analysis was conducted using a random-effect model. Risk of bias and quality assessment were performed using the ROBINS-I and QUADAS-2. The certainty of evidence was assessed using the GRADE methodology. RESULTS 744 obtunded trauma patients from six included studies were included. Among the 584 that had a negative CT scan, the pooled missed rate of clinically significant CSI using CT scans alone was 6 % (95 % CI: 0.02 to 0.17), and the pooled missed rate of CSI requiring treatment was 7 % (95 % CI: 0.02 to 0.18). High heterogeneity was observed among included studies (I² > 84 %). The overall risk of bias was moderate, and the quality of evidence was low due to the retrospective nature of the included studies and high heterogeneity. CONCLUSIONS Limited evidence published in the last decade found that CT scans alone may not be sufficient for detecting clinically significant CSI and injuries requiring treatment in obtunded adult patients with blunt trauma. IMPLICATIONS OF KEY FINDINGS Clinicians should be aware of the limitations of CT scans and consider using MRI when appropriate. Future research should focus on prospective studies with standardized outcome measures and uniform reporting.

Abstract
Background: Cervical spine clearance in intubated patients due to blunt trauma remains contentious. Accumulating evidence suggests that a normal computed tomography (CT) cervical spine can be used to clear the cervical spine and remove the collar in unconscious patients presenting to the emergency department. However, whether this strategy can safely be employed by critical care physicians with intubated patients admitted to the trauma intensive care unit (TICU) with cervical collars in situ, has not been definitively studied. Methods: A retrospective review of 730 intubated victims of trauma who presented to the Level 1 Trauma center of a tertiary hospital was conducted. The rates of missed cervical injuries in patients who had their cervical collars removed by intensive care physicians based on a normal CT scan of the cervical spine, were reviewed. Secondary outcomes included rates of collar-related complications. Results: Three hundred and fifty patients had their cervical collars removed by Trauma ICU doctors based on a high-quality, radiologist-interpreted normal CT cervical spine. Seventy percent of patients were sedated and/or comatose at the time of collar removal. Fifty-one percent of patients had concomitant traumatic brain injury. The average GCS at time of collar removal was 9. The incidence of missed neurological injury discerned clinically at time of both ICU and hospital discharge was nil (negative predictive value 100%). The rate of collar-related complications was 2%. Conclusion: Cervical collar removal by intensive care physicians on TICU following normal CT cervical spine, is safe, provided certain quality conditions related to the CT scan are met. Not removing the collar early may be associated with increased complications. An algorithm is suggested to assist critical care decision-making in this patient cohort.

Abstract
BACKGROUND Traumatic cervical spine (c-spine) injuries account for 10% of all spinal injuries. The c-spine is prone to injury by blunt acceleration/deceleration traumas. The Canadian C-Spine rule and NEXUS criteria guide clinical decision-making but lack consensus on imaging modality when necessary. This study aims to evaluate the sensitivity and specificity of CT, MRI, X-Ray, and, for the first time, LODOX-Statscan in identifying c-spine injuries in patients with blunt trauma and neck pain. METHODS We conducted a retrospective monocenter cohort study using patient data from the emergency department at Inselspital, Bern, Switzerland's largest level one trauma center. We identified patients presenting with trauma and neck pain during the recruitment period from 01.01.2012 to 31.12.2017. We included all patients that required a radiographic c-spine evaluation according to the NEXUS criteria. Certified spine surgeons reviewed each case, analyzed patient demographics, injury classification, trauma mechanism, and emergency management. The retrospective full case review was established as gold standard to decide whether the c-spine was injured. Sensitivity and specificity were calculated for CT, MRI, LODOX, and X-Ray imaging methods. RESULTS We identified 4996 patients, of which 2321 met the inclusion criteria. 91.3% (n = 2120) patients received a CT scan, 8.9% (n = 206) a MRI, 9.3% (n = 215) an X-ray, and 21.5% (n = 498) a LODOX scan. By retrospective case review, 186 participants were classified as injured. The sensitivity of CT was 88.6% (specificity 99%), and 89.8% (specificity 99.2%) with orthopedic surgeon consultation. MRI had a sensitivity of 88.5% (specificity of 96.9%); highlighting 14 cases correctly diagnosed as injured by MRI and misdiagnosed by CT. Projection radiography (36.4% sensitivity, 95.1% specificity) and LODOX (5.3% sensitivity, 100% specificity) were unsuitable for ruling out spinal injury. CONCLUSION While CT offers high sensitivity for detecting traumatic c-spine injury, MRI holds clinical significance in revealing injuries not recognized by CT in symptomatic patients. LODOX and projection radiography are insufficient for accurately ruling out c-spine injury. For patients with neurological symptoms, we recommend extended MRI use when CT scans are negative.

Abstract
Spinal bracing is a common non-surgical technique that allows clinicians to prevent and correct malformations or injuries of a patient's spinal column. This review will explore the current standards of practice on spinal brace utilization. Specifically, it will highlight bracing usage in traumatic injuries, pregnancy, pediatrics, osteoporosis, and hyperkyphosis; address radiological findings concurrent with brace usage; and provide an overview of the braces currently available and advancements in the field. In doing so, we aim to improve clinicians' understanding and knowledge of bracing in common spinal pathologies to promote their appropriate use and improve patient outcomes.

Abstract
BACKGROUND Traumatic pediatric cervical spine injury can be challenging to diagnose, and the clinical algorithms meant to aid physicians differ from adult trauma protocols. Despite the existence of standardized guidelines, imaging decisions may vary according to physician education, subjective assessment, and experience with pediatric trauma patients. Our study investigates the rates of pediatric posttraumatic cervical spine imaging across trauma centers, hypothesizing that more specialized centers will have lower rates of advanced cervical spine imaging. METHODS The 2015 to 2016 Trauma Quality Improvement Program database was reviewed for patients younger than 18 years- to assess rates of cervical spine imaging on presentation across different trauma centers. Propensity stratification logistic regression was performed controlling for patient- and center-specific variables. p Values less than 0.05 were considered significant. RESULTS Of 110,769 pediatric trauma patients, 35.2% were female, and the average age was 9.6 years. Overall, 3.6% had cervical spine computed tomography (CT) and less than 1% had cervical spine MRI or X-ray. Compared with all others, Level I trauma centers were significantly less likely to use cervical spine CT for the initial evaluation of younger (≤14 years) but not older trauma patients (adjusted odds ratio [AOR], 0.89; 95% confidence interval [CI], 0.80-0.99; AOR, 0.97; 95% CI, 0.87-1.09); Level I centers had higher odds of cervical spine MRI use, but only for patients 14 years or younger (AOR, 1.63; 95% CI, 1.09-2.44). Pediatric-designated trauma centers had significantly lower odds of cervical spine CT (≤14 years: AOR, 0.70; 95% CI, 0.63-0.78; >14 years: AOR, 0.67; 95% CI, 0.67-0.75) and higher odds of cervical spine X-ray (≤14 years: AOR, 4.75; 95% CI, 3.55-6.36; >14 years: AOR, 4.50; 95% CI, 2.72-7.45) for all ages, but higher odds of cervical spine MRI for younger patients only (≤14 years: AOR, 2.10; 95% CI, 1.38-3.21). CONCLUSION Level I and pediatric designations were associated with lower rates of cervical spine CT. Pediatric centers were also more likely to use cervical spine X-ray. This variability of imaging use further supports the need to disseminate and educate providers on pediatric-specific cervical spine evaluation guidelines.

Abstract
Despite the growing use of computed tomography (CT) and magnetic resonance imaging (MRI) in the study of spinal disorders, radiography still plays an important role in many conditions affecting the spine. However, the study and interpretation of spine radiograph is receiving less attention and radiologists are increasingly unfamiliar with the typical findings in normal and pathologic conditions of the spine. The aim of this article is to review the radiologic indications of radiograph in different pathologic conditions that affect the spine, including congenital, traumatic, degenerative, inflammatory, infectious and tumour disorders, as well as their main radiographic manifestations.

Abstract
No definite consensus exists for the clearance of the cervical spine (C-spine)
after blunt trauma, despite many validated algorithms, recommendations and
guidelines. We intend to answer the most relevant questions with which physicians
are confronted when clearing C-spines after blunt trauma in emergency departments
(EDs). To exclude significant C-spine injuries we designed an algorithm to be
compatible with clinical practice, to simplify patient management and avoid
unrewarding evaluation. We conducted an exploratory PubMed search including articles published from January
2000 to October 2018. Keywords used were “cervical spine”,
“injury”, “clearance”, “Canadian C-spine
Rule”, “CCR” and “national emergency x-radiography
utilization study”. Clinical and experimental studies were included in a
detailed review. We based our literature review on 33 articles. While answering fundamental triage
questions from daily clinical practice, the current literature is discussed in
detail. We designed an algorithm for the C-spine clearance suitable for any trauma
centre with a high-quality multiplanar reconstruction computerized tomography (CT)
scan continuously available. The high sensitivity of the Canadian C-spine Rule (CCR) prevents missing C-spine
injuries while limiting the amount of unnecessary radiologic examinations. Plain
radiographs were fully abandoned for C-spine clearance. A negative CT scan is
sufficient to clear the majority of C-spine injuries and allows for collar removal.
In case of motor symptoms or radio-clinical discrepancy, the advice of a specialized
spine surgeon must be requested. Magnetic resonance imaging must not be routinely
used. Neck pain despite negative imaging is not a reason to delay removal of stiff
cervical collars.

Abstract
Following a blunt trauma, the goal of the cervical spine evaluation is to identify any injuries that might require active management: either through continued use of a collar or surgical stabilization. This is achieved through a step-wise approach that considers the nature of the patient's trauma, presenting complaints, distracting injuries and capacity to cooperate with the examination. In the last 15 to 20 years, technological advances in radiographic imaging have improved clinicians' abilities to certify the cervical spine as free of injury following blunt trauma. Within the last decade, the use of CT has supplanted plain radiograph imaging as the standard screening modality. Although MRI is more sensitive than CT in identifying occult cervical injury, particularly ligamentous or soft-tissue trauma, the standard addition of MRI to CT evaluation alone does not significantly increase the detection of clinically important cervical injuries.

Abstract
BACKGROUND Cervical spine injuries (CSI) are rare within the pediatric population. Due to the significant consequences of missed CSI, children are often imaged excessively. In an attempt to decrease imaging of the cervical spine in children, we reviewed abnormal cervical radiographs (XR) to determine if the diagnosis of CSI could be made using a single-lateral cervical radiograph (LAT). Furthermore, we reviewed cervical computed tomography (CT) and magnetic resonance imaging (MRI) to ensure there were no missed CSI. METHODS Electronic medical records of trauma patients treated at a Level I Pediatric Trauma Center with abnormal XR findings followed by confirmatory CT or MRI between 2012 and 2017 were reviewed. All abnormal imaging on XR was compared with the LAT. In addition, all abnormal CTs and MRIs were reviewed to ensure there were no false negative XR. RESULTS A total of 3,735 XR were performed with 26 abnormal interpretations. All bony CSI were visualized on LAT. Confirmatory imaging found 13 (50%) were false positive and 13 (50%) were true positive. Secondary analysis of CT identified 12 injuries with prior XR; 8 of 12 LAT identifying the injury and 4 of 12 false positive on CT. Secondary analysis of MRI identified nine injuries with prior XR; 5 of 9 LAT identifying the injury. The four false-negative reads on MRI were ligamentous injuries. CONCLUSION Radiographs are commonly performed when evaluating CSI. In our population, initial assessment with a single LAT was equivalent to a multiple view XR. On secondary review, the only false-negative LAT reports were due to ligamentous injuries. This data suggests limiting exposure to LAT would accomplish the goal of reducing imaging without missing bony CSI and when ligamentous injury is suspected MRI should be the confirmatory study rather than CT.

Abstract
Every year in North America, approximately 3 million patients are evaluated for spinal injury. Of blunt trauma patients presenting to the emergency department, 3% to 4% will have a cervical spine injury, and up to 18% will suffer a thoracolumbar spine injury. Failure to identify an unstable spine injury can lead to devastating outcomes.

Abstract
BACKGROUND A missed cervical spinal injury could have devastating consequences. Patients with a suspected cervical spinal injury are kept in rigid collars for cervical immobilisation. Prolonged collar use has important clinical implications. A well-defined guideline related to the removal of cervical collars from adult obtunded blunt trauma patients has not been developed. AIM We sought to determine if Magnetic Resonance Imaging offered a definitive benefit over Computer Tomography with respect to patient management. METHOD We searched Ovid Online, EBSCO, NICE Evidence Journals, Medline, PubMED, BNI, CINAHL and Google Scholar as well as the grey literature. Data extraction and synthesis were performed on studies that compared the radiologic findings and clinical outcomes of Computer Tomography scan and Magnetic Resonance Imaging in this patient group. RESULTS There is evidence that supports the safe discontinuation of cervical collar use after a negative multidetector Computer Tomography scan result alone. Magnetic Resonance Imaging may detect a significant number of ligamentous injuries, but such injuries are rarely of clinical significance because they rarely alter clinical management. Its use should be limited to specific circumstances. CONCLUSION It is important for institutions to re-examine the latest evidence regarding cervical spinal clearance in order to update their guidelines.

Blunt cervical spine injury in adult polytrauma: incidence, injury patterns and predictors of significant ligament injury on CT. Clin Radiol 2017; 72:907-914. [PMID: 28803621 DOI: 10.1016/j.crad.2017.06.122] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2017] [Revised: 06/16/2017] [Accepted: 06/27/2017] [Indexed: 11/22/2022]
Abstract
AIM To describe the pattern of cervical spine fractures in adult major trauma and identify computed tomography (CT) parameters that can predict significant ligament injury when fractures are absent; to define the normal range for parameters used; and identify common variations due to position of cervical immobilisation in a trauma patient. MATERIALS AND METHODS In this retrospective study all polytrauma patients imaged using multidetector CT over a period of 5 years were identified. Patients with cervical spine fracture and suspected ligament injury in the absence of fracture were collated based on the polytrauma CT report. Predictors of ligament injury were defined based on published historical data on plain radiographs and posterior paraspinal fat pad assessment at CT. These parameters were recorded for each study with comparison to subsequent magnetic resonance imaging (MRI) as the reference standard. RESULTS Significant ligament injury on MRI was detected at the craniocervical junction, when CT showed a basion dens interval of >10 mm, widened incongruous C0/C1 facet joint space of >3 mm, and widened C1/2 facet joint space of >6 mm. In the subaxial cervical spine, facet subluxation >50% and obscured posterior paraspinal fat pad were the only reliable predictors of ligament injury, as confirmed on subsequent MRI. CONCLUSION When fractures are absent, signs of significant ligament injury on CT at the craniocervical junction were increased basion dens interval and widened facet joints. In the subaxial cervical spine, >50% subluxation of a facet joint and obscured posterior paraspinal fat pad are indicators of significant ligament injury.
