The association between cervical degenerative MRI findings and self-reported neck pain, disability and headache: a cross-sectional exploratory study. Chiropr Man Therap 2023; 31:45. [PMID: 37821958 PMCID: PMC10568844 DOI: 10.1186/s12998-023-00517-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 09/28/2023] [Indexed: 10/13/2023] Open
Abstract
BACKGROUND Neck pain and headache are highly prevalent conditions and leading causes of disability worldwide. Although MRI is widely used in the management of these conditions, there is uncertainty about the clinical significance of cervical MRI findings in patients with neck pain or headache. Therefore, this study aims to investigate the association between cervical degenerative MRI findings and self-reported neck pain, neck disability, and headache. METHODS This study was a secondary analysis of a cohort of patients with low back pain aged 18-40 years recruited from a non-surgical outpatient spine clinic. The cervical MRI and outcome measures used in this analysis were collected at a four-year follow-up (2014-2017). Self-reported outcome measures included neck pain intensity, neck disability as measured by the Neck Disability Index, and headache as measured by a single NDI item. Cervical MRI findings included disc degeneration, disc contour changes, and vertebral endplate signal changes (VESC). Multivariable logistic regression analyses, adjusted for age and sex, were used to analyse the associations between MRI findings and neck pain, neck disability, and headache. RESULTS A total of 600 participants who underwent MRI and completed the relevant questionnaires at follow-up were included. The median age was 37 years (interquartile range 31-41) and 325 (54%) were female. Of the included participants, 181 (31%) had moderate or severe neck pain, 274 (59%) had moderate or severe neck disability, 193 (42%) reported headaches, and 211 (35%) had one or more cervical degenerative MRI findings. Cervical disc degeneration and disc contour changes were positively associated with moderate or severe neck pain with odds ratio 1.6 (95% CI 1.1-2.4) and 1.6 (1.1-2.3), respectively. VESC was associated with moderate or severe neck disability with odds ratio 3.3 (1.3-8.4). No statistically significant associations were found between the MRI findings assessed and headache. CONCLUSIONS In this cross-sectional exploratory study, we found that cervical disc degeneration and disc contour changes were associated with neck pain, and VESC was associated with neck disability. None of the MRI findings were associated with headache. The results suggest that cervical degenerative changes may contribute to the aetiology of neck symptoms, but the associations are modest and cannot guide clinical decisions.

Abstract
PURPOSE To explore health professionals' acceptance of the guidelines for acute whiplash associated disorders (WAD), and to identify barriers and facilitators to adherence. MATERIALS AND METHODS Qualitative descriptive study involving focus group discussions among health professionals who treat people with WAD in primary and secondary care settings in New South Wales and Queensland, Australia. Twenty-eight health professionals (physiotherapists = 19; chiropractors = 6; osteopaths = 3) participated in six semi-structured focus group discussions that were held in independent offices in Sydney and Brisbane, Australia between September and December 2015. Discussions were audio recorded and verbatim, de-identified transcripts produced. Thematic analysis was conducted using an inductive approach to identify commonly held beliefs. RESULTS Acceptance of guideline recommendations appeared to be influenced by factors related to the guideline itself, practitioner and practice characteristics, and patient-related factors. Specifically, acceptance was hindered by conflicting belief systems, ambiguity in guideline recommendations, and patient characteristics and expectations. CONCLUSIONS Practitioners demonstrated a positive attitude towards the use of the guidelines in general; however, in some cases, acceptance of key recommendations appeared selective. Future guideline revision and implementation might focus on explaining the underlying principles of the guidelines, providing more detailed recommendations, and involving strategies that challenge inconsistent beliefs and promote informed decision-making. IMPLICATIONS FOR REHABILITATIONSelective acceptance of guideline recommendations in favour of those not requiring practice change may present a challenge for the implementation of evidence-based practice in the management of whiplash.Participants demonstrated variable, sometimes polar attitudes to guideline key messages and recommendations.Guideline developers need to focus more strongly on changing practitioner beliefs and attitudes, as well as better explaining the underlying principles of the guidelines, and providing more detailed recommendations.

COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2022; 219:106761. [PMID: 35344767 DOI: 10.1016/j.cmpb.2022.106761] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 03/07/2022] [Accepted: 03/15/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND AND OBJECTIVE Neural reflex is hypothesized as a regulating step in spine stabilizing system. However, neural reflex control is still in its infancy to consider in the previous finite element analysis of head-neck system for various applications. The purpose of this study is to investigate the influences of neural reflex control on neck biomechanical responses, then provide a new way to achieve an accurate biomechanical analysis for head-neck system with a finite element model. METHODS A new FE head-neck model with detailed active muscles and spinal cord modeling was established and globally validated at multi-levels. Then, it was coupled with our previously developed neuromuscular head-neck model to analyze the effects of vestibular and proprioceptive reflexes on biomechanical responses of head-neck system in a typical spinal injury loading condition (whiplash). The obtained effects were further analyzed by comparing a review of epidemiologic data on cervical spine injury situations. RESULT The results showed that the active model (AM) with neural reflex control obviously presented both rational head-neck kinematics and tissue injury risk referring to the previous experimental and epidemiologic studies, when compared with the passive model (PM) without it. Tissue load concentration locations as well as stress/strain levels were both changed due to the muscle activation forces caused by neural reflex control during the whole loading process. For the bony structures, the AM showed a peak stress level accounting for only about 25% of the PM. For the discs, the stress concentrated location was transferred from C2-C6 in the PM to C4-C6 in the AM. For the spinal cord, the strain concentrated locations were transferred from C1 segment to around C4 segment when the effects of neural reflex control were implemented, while the gray matter and white matter peak strains were reduced to 1/3 and 1/2 of the PM, respectively. All these were well correlated with epidemiological studies on clinical cervical spine injuries. CONCLUSION In summary, the present work demonstrated necessity of considering neural reflex in FE analysis of a head-neck system as well as our model biofidelity. Overall results also verified the previous hypothesis and further quantitatively indicated that the muscle activation caused by neural reflex is providing a protection for the neck in impact loading by decreasing the strain level and changing the possible injury to lower spinal cord level to reduce injury severity.

Abstract
Introduction It is not uncommon for patients with persistent neck pain after trauma despite negative cervical imaging to be discharged with a rigid collar. Protocols for these patients vary widely. Few studies have evaluated clinical outcomes after discharge. No studies have evaluated the patient’s experience in a cervical collar after discharge. Methods We evaluated adults with blunt trauma and negative cervical spine imaging who were discharged in a rigid cervical collar. Over a 19-month period, 45 patients were available for analyses. The primary outcome was any identified missed injuries after discharge. Secondary outcomes were the incidence of patients self-clearing from their collars and complications related to wearing a collar. Results There were no missed traumatic injuries on follow-up imaging. Twenty of 45 patients cleared themselves from the collar without a physician order. Twenty-four patients had their collars removed by a provider in the clinic between 1-84 days after injury. One patient removed the collar after being advised by a chiropractor. More than half of patients reported one or more complications from wearing the cervical collar including pain, skin irritation, problems sleeping, difficulty talking or swallowing. Conclusions Collar complications are frequent. Follow-up imaging did not change outpatient management. Our data suggests against the practice of discharging trauma patients home in a cervical collar with negative imaging and no focal neurologic deficit.

Abstract
The natural course of the whiplash disease is reconsidered in relation to the predominant view of its cause. It is assumed that a whiplash-type trauma is causing an acute tissue injury such as a distortion or sprain in the neck followed by neck pain and headache, which then tends to become a chronic pain condition. We conclude that the whiplash disease typically evolves following a minor trauma without any signs of a tissue injury. It presents with central neuromotor dysfunction, such as electromyography (EMG) hyperactivity and abnormal activation patterns associated with dyscoordination of the involved and adjacent muscle groups. This indicates a central neurological rather than a peripheral traumatic pathology. This view places the cause of the whiplash disease within the central nervous system, and, in concordance with the EMG abnormalities and motor dyscoordination, we suggest the term cervical spinal dyssynergia for this pathology. It provides a new paradigm for further investigations of this disease as well as a window for possible specific neuropharmacological therapy directed towards dysfunctional neuromotor control.

Abstract
ABSTRACT Knowledge of etiological mechanisms underlying whiplash-associated disorders is incomplete. Localisation and quantification of peripheral musculoskeletal injury and inflammation in whiplash-associated disorders would facilitate diagnosis, strengthen patients' subjective pain reports, and aid clinical decisions, all of which could lead to improved treatment. In this longitudinal observational study, we evaluated combined [11C]-D-deprenyl positron emission tomography and computed tomography after acute whiplash injury and at 6-month follow-up. Sixteen adult patients (mean age 33 years) with whiplash injury grade II were recruited at the emergency department. [11C]-D-deprenyl positron emission tomography and computed tomography, subjective pain levels, self-rated neck disability, and active cervical range of motion were recorded within 7 days after injury and again at 6-month follow-up. Imaging results showed possible tissue injuries after acute whiplash with an altered [11C]-D-deprenyl uptake in the cervical bone structures and facet joints, associated with subjective pain locale and levels, as well as self-rated disability. At follow-up, some patients had recovered and some showed persistent symptoms and reductions in [11C]-D-deprenyl uptake correlated to reductions in pain levels. These findings help identify affected peripheral structures in whiplash injury and strengthen the idea that positron emission tomography and computed tomography detectable organic lesions in peripheral tissue are relevant for the development of persistent pain and disability in whiplash injury.

Abstract
BACKGROUND The term whiplash describes the acceleration-deceleration mechanism of injury to the cervical spine. Whiplash injuries present with a variety of clinical and psychological manifestations, collectively termed as whiplash-associated disorders (WADs). Although largely self-limiting, some patients may experience long-lasting symptoms. This review aimed to summarize the current literature regarding the predictive value of cervical degeneration in the prognosis of patients with WAD. METHODS A comprehensive search of the literature was performed. Nine studies were identified, including 894 patients, with an age range between 16 and 76 years. RESULTS A statistically significant association was found between moderate facet joint degeneration and nonrecovery. Although no association was established between isolated disc degeneration and nonrecovery, total cervical degeneration (facet joint + disc degeneration) was shown to correlate with nonrecovery.All included studies demonstrated the lack of correlation between preexisting disc degeneration and clinical outcomes. Four studies showed a significant correlation between cervical degeneration and poor prognosis following whiplash injury. A significantly higher proportion of patients who remained symptomatic at 2 years following a whiplash injury had preexisting degenerative changes. CONCLUSIONS This review highlights the presence of significant variability in the existing literature concerning WAD in terms of study methodology, definitions of cervical degeneration, and outcome measures. Degenerative changes of the facet joint lead to alterations in its biomechanics. Several cadaveric, biomechanical, and clinical studies have demonstrated facet joints as a source of pain in patients with chronic WAD. We present moderate evidence to suggest that preexisting facet joint degeneration is a negative prognostic indicator for long-lasting symptoms in WAD. Conversely, preexisting disc degeneration is not associated with chronicity of WAD symptoms. We propose facet joint instability due to facet joint capsule rupture as a potential mechanism for nonrecovery. Further studies are needed to inform our knowledge of the long-term sequelae of WAD among patients with preexisting cervicalspine degeneration.

Abstract
INTRODUCTION Not all factors that predict persistent pain and disability following whiplash injury are known. In particular, few physical factors, such as changes in movement and muscle behaviour, have been investigated. The aim of this study is to identify predictive factors that are associated with the development of persistent pain and disability following a whiplash injury by combining contemporary measures of physical function together with established psychological and pain-related predictive factors. METHODS AND ANALYSIS A prospective observational study will recruit 150 consecutive eligible patients experiencing whiplash-related symptoms, admitted to a private physiotherapy clinic in Spain within 15 days of their whiplash injury. Poor outcome will be measured using the Neck Disability Index (NDI), defined as an NDI score of 30% or greater at 6 months post injury. Candidate predictors, including demographic characteristics, injury characteristics, pain characteristics, self-reported psychosocial factors and physical factors, will be collected at baseline (within 15 days of inception). Regression analyses will be performed to identify factors that are associated with persistent neck pain and disability over the study period. ETHICS AND DISSEMINATION The project has been approved by the Ethics Committee of the province of Malaga, Spain (#30052019). The results of this study will be published in peer-reviewed journals.

Abstract
OBJECTIVES The reason why some individuals develop chronic symptoms, whiplash-associated disorder, following whiplash trauma is poorly understood. We explored whether precollision pain-related diagnoses, medically unexplained symptoms, and psychiatric diagnoses are related to whiplash-associated disorder. MATERIALS AND METHODS A cohort of 719 individuals exposed to whiplash trauma and subsequently experiencing symptoms within 72 hours (whiplash-exposed cohort) and 3595 matched controls were included in this observational prospective study. At 12 months postcollision, the whiplash-exposed cohort rated their neck pain using the Visual Analog Scale. Data on health were obtained from the Danish National Patient Register for the whiplash-exposed cohort and for the controls for a 5-year period before collision. RESULTS The whiplash-exposed cohort had significantly increased incidences of precollision pain-related diagnoses: χ(1)=17.42, P<0.001 and medically unexplained symptoms: χ(1)=22.2, P<0.001 but not psychiatric diagnoses: χ(1)=3.60, P>0.05 compared with controls in the 5-year period. Participants from the whiplash-exposed cohort with precollision pain-related diagnoses (odds ratio=2.46; 95% confidence interval, 1.39; 4.35) and medically unexplained symptoms (odds ratio, 1.72; 95% confidence interval, 1.04; 2.84) had significantly increased odds for neck pain at follow-up. DISCUSSION Precollision pain and medically unexplained symptoms predict chronic neck pain following whiplash trauma. This may indicate that a sensitization process was initiated before the collision or that individuals with precollision low threshold for contacting health care services maintain this behavior postcollision. The collision may trigger existing individual vulnerabilities that constitute to be a risk factor for chronic whiplash.

Abstract
BACKGROUND CONTEXT Pre-existing radiological degenerative changes have not previously been considered a risk factor for nonrecovery from neck pain due to motor vehicle accidents (MVA). Results from previous studies are however often based on assessment of plain radiography or MRI and little consideration has been given to facet joints. Furthermore, previous studies have often lacked a validated scoring system for degenerative changes. PURPOSE To investigate the association between cervical degeneration on computed tomography (CT) and nonrecovery after whiplash trauma. STUDY DESIGN Longitudinal cohort study. PATIENT SAMPLE One hundred twenty-one patients attending the Emergency Department because of neck pain after MVA, 2015-2017, with a valid CT-scan of the cervical spine and completion of follow up after 6 months. OUTCOME MEASURES The primary outcome measure was self-perceived nonrecovery (yes/no) after 6 months. A secondary outcome measure was self-reported pain level (Numeric Rating Scale). METHODS Baseline data regarding demographics and health factors were gathered through a web-based questionnaire. Degeneration of facet joints and intervertebral discs was assessed on CT-scans according to a validated scoring system. Binary logistic regression was used to study the association between cervical degeneration and nonrecovery. RESULTS Moderate facet joint degeneration was associated with nonrecovery. In the group with moderate degree of facet joint degeneration, 69.6% reported nonrecovery compared with 23.6% among patients without any signs of degeneration (adjusted odds ratio 6.7 [95% confidence interval: 1.9-24.3]). There was no association between disc degeneration and nonrecovery. Combined facet joint degeneration and disc degeneration were associated with nonrecovery (adjusted odds ratio 6.2 [2.0-19.0]). CONCLUSIONS These results suggest that cervical degeneration, especially facet joint degeneration, is a risk factor for nonrecovery after whiplash trauma. We hypothesize that whiplash trauma can be a trigger for painful manifestation of previously asymptomatic facet joint degeneration.

A 20-year prospective longitudinal MRI study on cervical spine after whiplash injury: Follow-up of a cross-sectional study. J Orthop Sci 2019; 24:579-583. [PMID: 30553607 DOI: 10.1016/j.jos.2018.11.011] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Revised: 11/06/2018] [Accepted: 11/18/2018] [Indexed: 02/09/2023]
Abstract
BACKGROUND Some patients suffer from long-lasting symptoms after whiplash injury. However, there are few reports on the long-term changes in the cervical spine after whiplash injury using imaging tests. The purpose of this longitudinal study was to determine the changes on MRI of the cervical spine 20 years after whiplash injury, and to examine the relationships between changes in the cervical spine on MRI and changes in related clinical symptoms. METHODS Eighty-one subjects finally participated in this study (follow-up rate 16%). The mean follow-up duration was 21.7 years. All subjects filled out a questionnaire about their clinical symptoms. The MRI findings were assessed using numerical grading system applied in the original study. Statistic analyses were used to investigate whether the progression of each MRI finding was associated with the severity of neck pain, stiff shoulders, dizziness and tinnitus. RESULTS All subjects had complained of some clinical symptoms in the original study: 71 had neck pain, 53 stiff shoulders, and others. In the present study, 66 subjects (81.5%) complained of some clinical symptoms: 57 had stiff shoulders, 20 neck pain, and others. The progression of degeneration on MRI was observed in 95% of the subjects, with C4/5 and 5/6 being the most frequently involved levels. Changes in the severity of neck pain, stiff shoulders, dizziness and tinnitus over 20 years were not significantly associated with the progression of degenerative changes in the cervical spine on MRI. CONCLUSIONS Twenty years after whiplash injury, 95% of the subjects showed a progression of degeneration in the cervical spine. The progression of the intervertebral disc degeneration in the cervical spine on MRI after whiplash injury was not significantly associated with changes in the severity of related clinical symptoms, indicating that the degenerative changes on MRI may reflect the physiological aging process rather than post-traumatic sequelae.

Abstract
Objective To describe the development of a preventive educational video for patients exposed to whiplash trauma following motor vehicle accidents. Methods The development followed a systematic approach and was theory-driven supplemented with available empirical knowledge. The specific content was developed by a multidisciplinary group involving health professionals and visual production specialists. Results A 14-min educational video was created. The video content focuses on stimulating adaptive recovery expectations and preventing maladaptive illness beliefs. The video presents a multifactorial model for pain incorporating physiological and cognitive-behavioural aspects, advice on pain relief, and exercises. Subjects interviewed for a qualitative evaluation found the video reassuring and that it aligned well with verbal information received in the hospital. Conclusions The development of the visual educational intervention benefitted from a systematic development approach entailing both theoretical and research-based knowledge. The sparse evidence on educational information for acute whiplash trauma posed a challenge for creating content. Further knowledge is required regarding what assists recovery in the early stages of whiplash injuries in order to improve the development of educational interventions.

Abstract
Neck pain and whiplash injuries are a common presentation to the ED, and a frequent cause of disability globally. This rapid review investigated best practice for the assessment and management of musculoskeletal neck pain in the ED. PubMed, CINAHL, EMBASE, TRIP and the grey literature, including relevant organisational websites, were searched in 2017. Primary studies, systematic reviews and guidelines were considered for inclusion. English-language articles published in the past 12 years addressing acute neck pain assessment, management or prognosis in the ED were included. Data extraction was conducted, followed by quality appraisal to rate levels of evidence where possible. The search revealed 2080 articles, of which 51 were included (n = 22 primary articles, n = 13 systematic reviews and n = 16 guidelines). Consistent evidence was found to support the use of 'red flags' to screen for serious pathologies, judicious use of imaging through clinical decision rule application and promotion of functional exercise coupled with advice and reassurance. Clinicians may also consider applying risk-stratification methods, such as using a clinical prediction rule, to guide patient discharge and referral plans; however, the evidence is still emerging in this population. This rapid review provides clinicians managing neck pain in the ED a summary of the best available evidence to enhance quality of care and optimise patient outcomes.

Adoption and use of guidelines for whiplash: an audit of insurer and health professional practice in New South Wales, Australia. BMC Health Serv Res 2018; 18:622. [PMID: 30089495 PMCID: PMC6083615 DOI: 10.1186/s12913-018-3439-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Accepted: 08/01/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In Australia, the New South Wales (NSW) State Insurance Regulatory Authority has been continuously developing and implementing clinical practice guidelines to address the health and economic burden from whiplash associated disorders (WAD). Despite this, it is uncertain the extent to which the guidelines are followed. This study aimed to determine insurer and health professional compliance with recommendations of the 2014 NSW clinical practice guidelines for the management of acute WAD; and explore factors related to adherence. METHODS This was an observational study involving an audit of 288 randomly-selected claimant files from 4 insurance providers in NSW, Australia between March and October 2016. Data extracted included demographic, claim and injury details, use of health services, and insurer and health professional practices related to the guidelines. Analyses involved descriptive statistics and correlation analysis. RESULTS Median time for general practitioner medical consultation was 4 days post-injury and 25 days for physical treatment (e.g. physiotherapy). Rates of x-ray investigations were low (21.5%) and most patients (90%) were given active treatments in line with the guideline recommendations. The frequency of other practices recommended by the guidelines suggested lower guideline adherence in some areas such as; using the Quebec Task Force classification (19.9%); not using specialised imaging for WAD grades I and II (e.g. MRI, 45.8%); not using routine passive treatments (e.g. manual therapy, 94.0%); and assessing risk of non-recovery using relevant prognostic tools (e.g. Neck Disability Index, 12.8%). Over half of the claimants (59.0%) were referred to other professionals at 9-12 weeks post-injury, among which 31.2% were to psychologists and 68.8% to specialists (surgical specialists, 43.6%; WAD specialists, 20.5%). Legal representation and lodgment of full claim were associated with increased number of medical visits and imaging (ρ 0.23 to 0.3; p < 0.01). CONCLUSION There is evidence of positive uptake of some guideline recommendations by insurers and health professionals; however, there are practices that are not compliant and might lead to poor health outcomes and greater treatment cost. Organisational, regulatory and professional implementation strategies may be considered to change practice, improve scheme performance and ultimately improve outcomes for people with WAD.

Abstract
STUDY DESIGN Research. OBJECTIVE The goal of this study was to investigate whether Propionibacteria acnes infection of the intervertebral disc can be detected noninvasively by nuclear magnetic resonance (NMR) spectroscopy. SUMMARY OF BACKGROUND DATA Microbiological studies of surgical samples suggest that a significant subpopulation of back pain patients may have occult disc infection with P. acnes bacteria. This hypothesis is further supported by a double-blind clinical trial showing that back pain patients with Modic type 1 changes may respond to antibiotic treatment. Because significant side effects are associated with antibiotic treatment, there is a need for a noninvasive method to detect whether specific discs in back pain patients are infected with P acnes bacteria. METHODS P. acnes bacteria were obtained from human patients. NMR detection of a propionic acid (PA) in the bacteria extracts was conducted on 500 MHz high-resolution spectrometer, whereas in vivo NMR spectroscopy of an isolated bovine disk tissue infected with P. acnes was conducted on 7 T magnetic resonance imaging scanner. RESULTS NMR spectra of P. acnes metabolites revealed a distinct NMR signal with identical chemical shits (1.05 and 2.18 ppm) as PA (a primary P. acne metabolite). The 1.05 ppm signal does not overlap with other bacteria metabolites, and its intensity increases linearly with P. acnes concentration. Bovine disks injected with P. acnes bacteria revealed a very distinct NMR signal at 1.05 ppm, which linearly increased with P. acnes concentration. CONCLUSION The 1.05 ppm NMR signal from PA can be used as a marker of P. acnes infection of discs. This signal does not overlap with other disc metabolites and linearly depends on P. acnes concentration. Consequently, NMR spectroscopy may provide a noninvasive method to detect disc infection in the clinical setting. LEVEL OF EVIDENCE N/A.

Abstract
BACKGROUND CONTEXT Magnetic resonance imaging (MRI) has the potential to identify pathology contributing to neck pain. However, the importance of findings on MRI remains unclear. PURPOSE We aimed to investigate whether findings on cervical spine MRI predict future neck pain. STUDY DESIGN A systematic review was carried out. PATIENT SAMPLE People with or without neck pain comprised the study sample. OUTCOME MEASURES Clinically important neck pain outcomes such as pain and disability. METHODS The review protocol was registered on PROSPERO [CRD42016049228]. MEDLINE, CINAHL, and EMBASE databases were searched. Prospective cohort studies investigating the association between baseline MRI findings and clinical outcome were included. Cohorts with serious underlying diseases as the cause of their neck pain were excluded. Associations between MRI findings and neck pain outcomes were extracted from the included studies. RESULTS A total of 12 studies met all inclusion criteria. Eight studies presented data on participants with current neck pain, two studies included a mixed sample, and two studies included a sample of participants with no current neck pain. Because of the heterogeneity between the studies in terms of MRI findings, populations, and clinical outcomes investigated, it was not possible to pool the results. No consistent associations between MRI findings and future outcomes were identified. Single studies of populations with neck pain reported significant associations for neck muscle fatty infiltrate (risk ratio [RR]: 21.00, 95% confidence interval [CI]: 2.97-148.31) with persistent neck disability; disc protrusion (mean difference ranged from -1.83 to -2.88 on a 10-point pain scale), and disc degeneration (RR: 0.59; 95% CI: 0.36-0.98) with neck pain. In a population without pain, the development of foraminal stenosis over a 10-year period was associated with development of neck pain (RR: 2.99; 95% CI: 1.23-7.23). CONCLUSION The limited number, heterogeneity, and small sample size of the included studies do not permit definitive conclusions on the association between MRI findings of the cervical spine with future neck pain.

Abstract
STUDY DESIGN This is a retrospective control study. OBJECTIVE We aimed to determine whether preexisting cervical disk degeneration is a prognostic factor in Whiplash-associated disorder (WAD). SUMMARY OF BACKGROUND DATA WAD is a common injury of traffic accident and has a broad range of prognoses. Although numerous studies have investigated prognostic factors in WAD, few have evaluated the effect of preexisting disk degeneration. MATERIALS AND METHODS This study involved 45 consecutive patients with grade I or II WAD having advanced disk degeneration (at least 1 disk of Miyazaki grade≥III on magnetic resonance imaging) and a control cohort of 52 patients with no or mild disk degeneration (all disks having Miyazaki grades≤II). Clinical assessment included pain severity (assessed by the visual analog scale), neck pain-related disability (assessed by the neck disability index), and physical and mental health condition [assessed by the short-form 36 (SF-36) physical composite score and SF-36 mental composite score, respectively]. Changes in each parameter were evaluated at baseline and at 3-month, 6-month, and 1-year follow-ups and compared between the 2 groups. RESULTS There were no differences between the 2 groups regarding demographics and baseline outcome parameters (all P>0.05). There were also no differences in improvement in visual analog scale for neck pain, neck disability index, SF-36 physical composite score, or SF-36 mental composite score between the 2 groups (all P>0.05) for each visit. The number of claim closures was significantly lower among patients with advanced degeneration than among controls at 6-month and 1-year follow-ups (P=0.004 and 0.006, respectively). CONCLUSIONS In the present study, the clinical presentation and prognosis of WAD were not affected by preexisting disk degeneration. However, claim closure was delayed in patients with preexisting disk degeneration. These results suggest that misunderstanding of disk degeneration on magnetic resonance imaging may create persistent illness and lead to continued compensation in WAD.

Abstract
The main concern with whiplash is that a large proportion of whiplash patients experience disabling symptoms or whiplash-associated disorders (WAD) for months if not years following the accident. Therefore, identifying early prognostic factors of WAD development is important as WAD have widespread clinical and economic consequences. In order to tackle that question, our study was specifically aimed at combining several methods of investigation in the same WAD patients at the acute stage and 6 months later. Our longitudinal, open, prospective, multi-center study included 38 whiplash patients, and 13 healthy volunteers matched for age, gender, and socio-economic status with the whiplash group. Whiplash patients were evaluated 15-21 days after road accident, and 6 months later. At each appointment, patients underwent a neuropsychological evaluation, a full clinical neurological examination, neurophysiological and postural tests, oto-neurological tests, cervical spine cord magnetic resonance imaging (MRI) with tractography (DTI). At 6 months, whiplash patients were categorized into two subgroups based on the results of the Diagnostic and Statistical Manual of Mental Disorders as having either favorable or unfavorable progression [an unfavorable classification corresponding to the presence of post-concussion symptom (PCS)] and we searched retrospectively for early prognostic factors of WAD predicting the passage to chronicity. We found that patients displaying high level of catastrophizing at the acute stage and/or post-traumatic stress disorder associated with either abnormalities in head or trunk kinematics, abnormal test of the otolithic function and at the Equitest or a combination of these syndromes, turned to chronicity. This study suggests that low-grade whiplash patients should be submitted as early as possible after the trauma to neuropsychological and motor control tests in a specialized consultation. In addition, they should be evaluated by a neuro-otologist for a detailed examination of vestibular functions, which should include cervical vestibular evoked myogenic potential. Then, if diagnosed at risk of WAD, these patients should be subjected to an intensive preventive rehabilitation program, including vestibular rehabilitation if required.

Abstract
OBJECTIVE To determine the effectiveness and risks of fluoroscopically-guided cervical medial branch thermal radiofrequency neurotomy (CMBTRFN) for treating chronic neck pain of zygapophysial joint origin. DESIGN Systematic review of the literature with comprehensive analysis of the published data. INTERVENTIONS Four reviewers formally trained in evidence-based medicine searched the literature on CMBTRFN. Each assessed the methodologies of studies found and appraised the quality of evidence presented. OUTCOME MEASURES The primary outcomes assessed were 100% relief of pain 6 and 12 months after treatment. Other outcomes were noted if reported. The evidence was evaluated in accordance with the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system. RESULTS The searches yielded eight primary publications on the effectiveness of the procedure. The evidence shows a majority of patients were pain free at 6 months and over a third were pain free at 1 year. The number needed to treat for complete pain relief at 6 months is 2. The evidence of effectiveness is of high quality according to the GRADE system. Twelve papers were found reporting unwanted effects, most of which are minor and temporary. No serious complications have ever been reported from procedures performed according to the published guidelines. The evidence of risks is of low quality according to the GRADE system. CONCLUSIONS If performed as described in the International Spine Intervention Society Guidelines, fluoroscopically-guided CMBTRFN is effective for abolishing zygapophysial joint pain and carries only minor risks.

Abstract
Spinal injury following inertial loading of the head and neck (whiplash) is a common sequel of low speed traffic crashes. A variety of non-musculoskeletal injuries have been described in association with injury to the spine following whiplash trauma, including traumatic brain injury, vestibular derangement, and cranial nerve injury, among others. Vascular injuries in the head and neck have, however, only rarely been described. We present the case of a middle-aged male who sustained an ultimately fatal injury that resulted from injury to the internal carotid artery (ICA) and intracerebral vascular structures following a hard braking maneuver, with no direct head- or neck contact with the vehicular interior. Based on this unusual mechanism of injury we reviewed hospital data from the United States nationwide inpatient database (NIS) to assess the frequency of similar injuries reportedly resulting from traffic crashes. The post-mortem examination revealed a left internal carotid artery dissection associated with subarachnoid hemorrhage (SAH). Based on the close temporal association, the absent prior history, and the plausibility of the injury mechanism, the injury was attributed to the braking maneuver. An analysis of NIS data demonstrated that the prevalence of subarachnoid hemorrhage is significantly higher when there is a traumatic etiology, and higher yet when the trauma is a traffic crash (odds ratio 3.3 and 4.3, respectively). The presented case, together with the hospital inpatient data analysis, indicate that although SAH in combination with ICA dissection is relatively rare, it is substantially more probable following a traffic crash. In a clinical or forensic setting the inference that magnitude of a trauma was low should not serve as a basis for either excluding a cervical artery dissection from a differential diagnosis, or for excluding the trauma as a cause of a diagnosed dissection. This case report illustrates a rare fatal outcome of inertial load to the head and neck induced by a sudden braking event in a commonly experienced non-collision traffic incident. The likely mechanism of injury resulted from interaction between the occupant and the 3-point seat belt. These findings indicate that ICA dissections are substantially more likely to be associated with SAH following head and neck trauma, regardless of the magnitude of the traumatic event or whether an impact was involved.

Abstract
STUDY DESIGN A prospective observational cohort study of alert, neurologically intact trauma patients presenting to the emergency department with midline cervical tenderness. Screening cervical magnetic resonance imaging (MRI) had been conducted after negative computed tomography (CT) when tenderness was persistent. OBJECTIVE To determine the association of acute findings and demographic characteristics with any long-term neck disability, and with time to return to work in such patients. SUMMARY OF BACKGROUND DATA The relationship between acute findings and outcomes in these patients is unknown, and we hypothesized that outcomes at 12 months would correlate with acute clinical signs and symptoms, MRI findings, and mechanisms of injury. METHODS Patients at a Level 1 trauma center with persistent midline cervical tenderness in the absence of evidence of intoxication, painful distracting injury, persistently abnormal neurology, or acute CT findings, who underwent early cervical MRI under the institutional protocol, were reviewed in the outpatient spine clinic after discharge. In addition, the factors associated with neck disability and time to return to work were examined at follow-up at 12 months after presentation. RESULTS There were 162 of 178 patients available for follow-up at 12 months (91%). Of these, 46% had MRI-identified cervical spine injury at their initial examination, and 22% had required clinical management, including 2.5% with operative stabilization. Neck disability was present in 43% of patients and was associated with depressive symptoms, workers' compensation, and low annual income. Delay in return to work was associated with the presence of minor limb/other fractures and depressive symptoms, whereas patients on high annual incomes were found to return to work more quickly. CONCLUSION Surprisingly in these acute trauma patients, MRI-detected injury, clinical factors, and injury mechanism were not found to be associated with long-term patient outcomes. As a result, a trial of a more targeted, individual return to work plan, including strategies aimed at improving physical and psychological function, may now be justified to optimize long-term recovery, reduce health resource costs, and maximize economic productivity through early return to work.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To update a previous review and meta-analysis on risk factors for persistent problems following whiplash secondary to a motor vehicle accident. BACKGROUND Prognosis in whiplash-associated disorder (WAD) has become an active area of research, perhaps owing to the difficulty of treating chronic problems. A previously published review and meta-analysis of prognostic factors included primary sources up to May 2007. Since that time, more research has become available, and an update to that original review is warranted. METHODS A systematic search of international databases was conducted, with rigorous inclusion criteria focusing on studies published between May 2007 and May 2012. Articles were scored, and data were extracted and pooled to estimate the odds ratio for any factor that had at least 3 independent data points in the literature. RESULTS Four new cohorts (n = 1121) were identified. In combination with findings of a previous review, 12 variables were found to be significant predictors of poor outcome following whiplash, 9 of which were new (n = 2) or revised (n = 7) as a result of additional data. The significant variables included high baseline pain intensity (greater than 5.5/10), report of headache at inception, less than postsecondary education, no seatbelt in use during the accident, report of low back pain at inception, high Neck Disability Index score (greater than 14.5/50), preinjury neck pain, report of neck pain at inception (regardless of intensity), high catastrophizing, female sex, WAD grade 2 or 3, and WAD grade 3 alone. Those variables robust to publication bias included high pain intensity, female sex, report of headache at inception, less than postsecondary education, high Neck Disability Index score, and WAD grade 2 or 3. Three existing variables (preaccident history of headache, rear-end collision, older age) and 1 additional novel variable (collision severity) were refined or added in this updated review but showed no significant predictive value. CONCLUSION This review identified 2 additional prognostic factors and refined the estimates of 7 previously identified factors, bringing the total number of significant predictors across the 2 reviews to 12. These factors can be easily identified in a clinical setting to provide estimates of prognosis following whiplash.

Abstract
STUDY DESIGN A retrospective imaging and clinical study. OBJECTIVE To evaluate the extraneural soft-tissue damage and its clinical relevance in patients with traumatic cervical spinal cord injury (SCI) without major bone injury. SUMMARY OF BACKGROUND DATA To date, various kinds of cervical discoligamentous injuries have been demonstrated on magnetic resonance images in patients with SCI without bony injury. However, it has not been clear whether these magnetic resonance imaging abnormalities are actually related to spinal segmental instability and the patients' neurological status. METHODS Eighty-eight adult patients with acute traumatic cervical SCI without major bone injury were examined by flexion-extension lateral radiographs and magnetic resonance images within 2 days after trauma. We excluded patients with flexion recoil injury; therefore, most of the patients included were considered to have sustained a hyperextension injury. Instability of the injured cervical segment was defined when there was more than 3.5-mm posterior translation and/or more than a 11° difference in the intervertebral angle between the site of interest and adjacent segments. The neurological status was evaluated according to the American Spinal Injury Association motor score. RESULTS On magnetic resonance images, the damage to the anterior longitudinal ligament and intervertebral disc were apparent in 44 and 37 patients, respectively. Various degrees of prevertebral fluid collection (prevertebral hyperintensity) were demonstrated in 76 patients. These magnetic resonance imaging abnormalities were significantly associated with initial cervical segmental instability as judged by flexion-extension radiographs. Interestingly, the American Spinal Injury Association motor score had a significant association with either magnetic resonance imaging abnormalities or segmental instability but not with the cervical canal diameter. CONCLUSION A considerable proportion of the patients with traumatic cervical SCI without major bone injury were shown to have various types of soft-tissue damage associated with cervical segmental instability at the early stages of the injury. The severity of paralysis greatly depended on these discoligamentous injuries.

Abstract
STUDY DESIGN Nonsystematic review. OBJECTIVE Review of prognostic indicators for outcome after whiplash injury and the implications for clinical practice and future research. SUMMARY OF BACKGROUND DATA The capacity to predict outcome after whiplash injury is important to guide the management of the condition. There have now been numerous cohort studies and several systematic reviews of prognosis. It is not clear if the current knowledge of prognostic indicators is useful for clinical practice and to improve outcomes after injury. METHODS Nonsystematic review of research investigating the prediction of chronic pain/disability and psychological outcomes after whiplash injury. RESULTS There remains considerable uncertainty surrounding the identification of clear prognostic indicators after whiplash injury. All systematic reviews note the moderate or lower quality if primary cohort studies and only one systematic review performed meta-analysis. There have been no studies attempting validation of predictive models. At the present time, the knowledge base stands that higher initial pain levels are the most consistent predictor of poor functional recovery. Additional promising factors include physical factors of cold hyperalgesia and loss of neck range of movement, although the latter is inconsistent. Psychological factors of pain catastrophizing, symptoms of post-traumatic stress and recovery perceptions are also prognostic of poor recovery and the presence of depressed mood is inconsistent. Further research is needed to validate predictive models, investigate interactions between factors, and to determine whether modification of predictors is possible and leads to improved outcomes. CONCLUSION The understanding of factors predictive of poor recovery after whiplash injury is evolving. Although more research is required to validate predictive models, some factors show consistent predictive capacity and could be used in clinical practice as potential indicators of poor recovery. It is not known if the specific targeting of modifiable prognostic indicators can be achieved or will lead to improved outcomes.

Abstract
Formulating an expert opinion on whiplash injuries requires that consideration be given to biomechanical, orthopedic, neurological, psychiatric and medicolegal aspects. The greatest difficulties are encountered in cases of mild whiplash where patients complain of constant pain without any physical correlative. Diverse assessments and principles for approving a claim are reflected in the fact that the prevalence of chronic spine pain after whiplash injuries (late whiplash syndrome) varies between 16% and 71% in different countries, and the proportion of whiplash injuries involved in petitions for compensation differs greatly across Europe (UK 75%, Germany 47%, Finland 8.5% and France 3% of all personal injuries).Important biomechanical, orthopedic, neurological, psychiatric and medicolegal aspects of expert testimony on whiplash associated disorders (WAD) are delineated.

Abstract
STUDY OBJECTIVE We aim to determine the prevalence and factors associated with cervical discoligamentous injuries detected on magnetic resonance imaging (MRI) in acute, alert, neurologically intact trauma patients with computed tomography (CT) imaging negative for acute injury and persistent midline cervical spine tenderness. We present the cross-sectional analysis of baseline information collected as a component of a prospective observational study. METHODS Alert, neurologically intact trauma patients presenting to a Level I trauma center with CT negative for acute injury, who underwent MRI for investigation of persistent midline cervical tenderness, were prospectively recruited. Deidentified images were assessed, and injuries were identified and graded. Outcome measures included the presence and extent of MRI-detected injury of the cervical ligaments, intervertebral discs, spinal cord and associated soft tissues. RESULTS There were 178 patients recruited during a 2-year period to January 2009. Of these, 78 patients (44%) had acute cervical injury detected on MRI. There were 48 single-column injuries, 15 two-column injuries, and 5 three-column injuries. Of the remaining 10 patients, 6 had isolated posterior muscle edema, 2 had alar ligamentous edema, 1 had epidural hematoma, and 1 had atlanto-occipital edema. The injuries to 38 patients (21%) were managed clinically; 33 patients were treated in cervical collars for 2 to 12 weeks, and 5 patients (2.8%) underwent operative management, 1 of whom had delayed instability. Ordinal logistic regression revealed that factors associated with a higher number of spinal columns injured included advanced CT-detected cervical spondylosis (odds ratio [OR] 11.6; 95% confidence interval [CI] 3.9 to 34.3), minor isolated thoracolumbar fractures (OR 5.4; 95% CI 1.5 to 19.7), and multidirectional cervical spine forces (OR 2.5; 95% CI 1.2 to 5.2). CONCLUSION In patients with cervical midline tenderness and negative acute CT findings, we found that a subset of patients had MRI-detected cervical discoligamentous injuries and that advanced cervical spine degeneration evident on CT, minor thoracolumbar fracture, and multidirectional cervical spine forces were associated with increased injury extent. However, a larger study is required to validate which variables may reliably predict clinically important injury in such patients, thereby indicating the need for further radiographic assessment.

Abstract
There are few diagnostic tools for chronic musculoskeletal pain as structural imaging methods seldom reveal pathological alterations. This is especially true for Whiplash Associated Disorder, for which physical signs of persistent injuries to the neck have yet to be established. Here, we sought to visualize inflammatory processes in the neck region by means Positron Emission Tomography using the tracer 11C-D-deprenyl, a potential marker for inflammation. Twenty-two patients with enduring pain after a rear impact car accident (Whiplash Associated Disorder grade II) and 14 healthy controls were investigated. Patients displayed significantly elevated tracer uptake in the neck, particularly in regions around the spineous process of the second cervical vertebra. This suggests that whiplash patients have signs of local persistent peripheral tissue inflammation, which may potentially serve as a diagnostic biomarker. The present investigation demonstrates that painful processes in the periphery can be objectively visualized and quantified with PET and that 11C-D-deprenyl is a promising tracer for these purposes.

Does cervical kyphosis relate to symptoms following whiplash injury? ACTA ACUST UNITED AC 2011; 16:378-83.

Abstract
The mechanisms for developing long-lasting neck pain after whiplash injuries are still largely unrevealed. In the present study it was investigated whether a kyphotic deformity of the cervical spine, as opposed to a straight or a lordotic spine, was associated with the symptoms at baseline, and with the prognosis one year following a whiplash injury. MRI was performed in 171 subjects about 10 d after the accident, and 104 participated in the pain recording at 1-year follow-up. It was demonstrated that postures as seen on MRI can be reliably categorized and that a straight spine is the most frequent appearance of the cervical spine in supine MRI. In relation to symptoms it was seen that a kyphotic deformity was associated with reporting the highest intensities of headache at baseline, but not with an increased risk of long-lasting neck pain or headache. In conclusion, a kyphotic deformity is not significantly associated with chronic whiplash associated pain. Moreover, it is a clear clinical implication that pain should not be ascribed to a straight spine on MRI. We suggest that future trials on cervical posture focus upon the presence of kyphotic deformity rather than just on the absence of lordosis.

Abstract
Background Upper neck ligament high-signal changes on magnetic resonance imaging (MRI) have been found in patients with whiplash-associated disorders (WAD) but also in non-injured controls. The clinical relevance of such changes is controversial. Their prognostic role has never been evaluated. The purpose of this study was to examine if alar and transverse ligament high-signal changes on MRI immediately following the car accident are related to outcome after 12 months for patients with acute WAD grades 1-2. Methods Within 13 days after a car accident, 114 consecutive acute WAD1-2 patients without prior neck injury or prior neck problems underwent upper neck high-resolution proton-weighted MRI. High-signal changes of the alar and transverse ligaments were graded 0-3. A questionnaire including the impact of event scale for measuring posttraumatic stress response and questions on patients' expectations of recovery provided clinical data at injury. At 12 months follow-up, 111 (97.4%) patients completed the Neck Disability Index (NDI) and an 11-point numeric rating scale (NRS-11) on last week neck pain intensity. Factors potentially related to these outcomes were assessed using multiple logistic regression analyses. Results Among the 111 responders (median age 29.8 years; 63 women), 38 (34.2%) had grades 2-3 alar ligament changes and 25 (22.5%) had grades 2-3 transverse ligament changes at injury. At 12 months follow-up, 49 (44.1%) reported disability (NDI > 8) and 23 (20.7%) neck pain (NRS-11 > 4). Grades 2-3 ligament changes in the acute phase were not related to disability or neck pain at 12 months. More severe posttraumatic stress response increased the odds for disability (odds ratio 1.46 per 10 points on the impact of event scale, p = 0.007) and so did low expectations of recovery (odds ratio 4.66, p = 0.005). Conclusions High-signal changes of the alar and transverse ligaments close after injury did not affect outcome for acute WAD1-2 patients without previous neck problems. High-resolution upper neck MRI has limited value for the initial examination and follow-up of such patients.

STUDY DESIGN A prospective 10-year follow-up study of patients with whiplash-associated disorders (WAD) and asymptomatic volunteers. OBJECTIVE To clarify long-term impact of whiplash injury on patient's symptoms and on magnetic resonance imaging (MRI) findings of the cervical spine. SUMMARY OF BACKGROUND DATA Long-term prognosis of WAD has not been fully elucidated. METHODS Between 1993 and 1996, we conducted cross-sectional comparative study of 508 acute WAD patients and 497 asymptomatic volunteers, all of whom underwent MRI of the cervical spine. For this follow-up study, 133 WAD patients and 223 control subjects were recruited again. All participants underwent follow-up MRI and physical examination, and answered to questionnaires regarding neck symptoms. Evaluation of MRI included decrease in signal intensity of discs, posterior disc protrusion, disc space narrowing, and foraminal stenosis using 2 to 4 numerical grades. Increase in the numerical grades by one or more was considered to be progression of degenerative changes. RESULTS Progression of decrease in signal intensity was observed in 109 WAD patients (82.0%), and 132 control subjects (59.2%), (age, sex adjusted odds ratio [OR]: 3.06), posterior disc protrusion in 101 (75.9%) and in 155 (69.5%) (OR = 1.46), disc space narrowing in 33 (24.8%) and in 59 (26.5%) (OR = 0.98), and foraminal stenosis in 6 (4.5%), and in 20 (9.0%) (OR = 0.52), respectively. Neck pain was observed in 34 WAD patients (25.6%) and 22 control subjects (9.9%) (P < 0.0001). There was no statistically significant correlation between neck pain and progression in each MR finding in either group. CONCLUSION The results of this study suggest that, although some WAD patients are more likely to suffer from long-lasting neck pain, MRI findings cannot explain the symptoms.

Abstract
The purpose of this study was to investigate the effect of age, anthropometrics and cervical range of motion upon synovial fold volume. Ten healthy female subjects aged 20-40 years were included in the study. Age, height, body mass, dimensions of the head and neck and cervical range of motion of each subject were measured. Magnetic resonance (MR) images of the cervical spine were acquired; the volume of the ventral and dorsal synovial folds of the right and the left lateral atlanto-axial joints was measured using seed growing and thresholding methods. Using Spearman's correlation coefficient, it was determined that there was no correlation between synovial fold volume and age. Synovial fold volume was positively correlated with subject height and neck length but negatively correlated with body mass, body mass index and the circumference of the head and neck. The relationship between synovial fold volume and range of cervical motion varied with the plane of movement. The ability to image the synovial folds of the lateral atlanto-axial joints using MR imaging to determine their normal morphology provides the basis for investigating synovial fold pathology in patients with neck pain and headache.
