Quality of Reporting Using Good Reporting of A Mixed Methods Study Criteria in Chiropractic Mixed Methods Research: A Methodological Review.

OBJECTIVE: The purpose of this review was to examine the reporting in chiropractic mixed methods research using Good Reporting of A Mixed Methods Study (GRAMMS) criteria. METHODS: In this methodological review, we searched MEDLINE, Embase, CINAHL, and the Index to Chiropractic Literature from the inception of each database to December 31, 2020, for chiropractic studies reporting the use of both qualitative and quantitative methods or mixed qualitative methods. Pairs of reviewers independently screened titles, abstracts, and full-text studies, extracted data, and appraised reporting using the GRAMMS criteria and risk of bias with the Mixed Methods Appraisal Tool (MMAT). Generalized estimating equations were used to explore factors associated with reporting using GRAMMS criteria. RESULTS: Of 1040 citations, 55 studies were eligible for review. Thirty-seven of these 55 articles employed either a multistage or convergent mixed methods design, and, on average, 3 of 6 GRAMMS items were reported among included studies. We found a strong positive correlation in scores between the GRAMMS and MMAT instruments (r = 0.78; 95% CI, 0.66-0.87). In our adjusted analysis, publications in journals indexed in Web of Science (adjusted odds ratio = 2.71; 95% CI, 1.48-4.95) were associated with higher reporting using GRAMMS criteria. Three of the 55 studies fully adhered to all 6 GRAMMS criteria, 4 studies adhered to 5 criteria, 10 studies adhered to 4 criteria, and the remaining 38 adhered to 3 criteria or fewer. CONCLUSION: Our findings suggest that reporting in chiropractic mixed methods research using GRAMMS criteria was poor, particularly among studies with a higher risk of bias.

The association between chiropractic integration in an Ontario community health centre and continued prescription opioid use for chronic non-cancer spinal pain: a sequential explanatory mixed methods study.

BACKGROUND: Emerging evidence suggests that access to chiropractic care may reduce the likelihood of initiating an opioid prescription for spinal pain; however, the impact of chiropractic care for patients already prescribed opioids is uncertain. We undertook a sequential explanatory mixed methods study to evaluate the association between initiating chiropractic care and continued opioid use among adult patients attending an Ontario community health centre (CHC) and receiving opioid therapy for chronic non-cancer spinal pain. METHODS: We conducted a retrospective cohort study of 210 patient records between January 1, 2014 and December 31, 2020. We used generalized estimating equations, adjusted for patient demographics, co-morbidities, visit frequency, and calendar year, to evaluate the association between receipt versus non-receipt of chiropractic services and continued opioid use (e.g., unique opioid fills, number of refills, and dosages) up to one year following the index chiropractic visit. We also completed follow-up interviews with 14 patients and nine general practitioners from the CHC and integrated these data with our quantitative findings. RESULTS: Over 12-month follow-up, there were lower rates of opioid fills (incidence rate ratio [IRR] = 0.66; 95% confidence interval [CI], 0.52-0.83) and refills (IRR = 0.27; 95% CI, 0.17-0.42) among chiropractic recipients (n = 49) versus non-recipients (n = 161). Although patients who did and did not receive chiropractic care began the study with the same dose of opioids, recipients were less likely to be prescribed higher-dose opioids (i.e., ≥ 50 mg morphine equivalents daily) compared to non-recipients at three months (odds ratio [OR] = 0.14; 95% CI, 0.04-0.47), six months (OR = 0.14; 95% CI, 0.05-0.40), nine months (OR = 0.19; 95% CI, 0.07-0.57), and 12 months (OR = 0.22; 95% CI, 0.08-0.62). Interviews suggested that patient self-efficacy, limited effectiveness of opioids for chronic pain, stigma regarding use of opioids, and access to chiropractic treatment were important influencing factors. CONCLUSION: We found that continued prescription opioid use among patients with chronic non-cancer spinal pain who received chiropractic care was lower than in patients who did not receive chiropractic care. Four themes emerged in our qualitative interviews to help provide a richer understanding of this association. Randomized controlled trials are needed to establish the effect of chiropractic care on opioid use for chronic spinal pain.

Association of Chiropractic Care With Receiving an Opioid Prescription for Noncancer Spinal Pain Within a Canadian Community Health Center: A Mixed Methods Analysis.

OBJECTIVE: The purpose of this study was to examine the association between receipt of chiropractic services and initiating a prescription for opioids among adult patients with noncancer spinal pain in a Canadian community health center. METHODS: In this sequential explanatory mixed methods analysis, we conducted a retrospective study of 945 patient records (January 2014 to December 2020) and completed interviews with 14 patients and 9 general practitioners. We used Cox proportional hazards regression analyses, adjusted for patient demographics, comorbidities, visit frequency, and calendar year to evaluate the association between receipt of chiropractic care and time to first opioid prescription up to 1 year after presentation. Qualitative data were analyzed thematically and integrated with our quantitative findings. RESULTS: There were 24% of patients (227 of 945) with noncancer spinal pain who received a prescription for opioids. The risk of initiating a prescription for opioids at 1 year after presentation was 52% lower in chiropractic recipients vs nonrecipients (hazard ratio [HR], 0.48; 99% confidence interval [CI], 0.29-0.77) and 71% lower in patients who received chiropractic services within 30 days of their index visit (HR, 0.29; 99% CI, 0.13-0.68). Patients whose index visit date was in a more recent calendar year were also less likely to receive opioids (HR, 0.86; 99% CI, 0.76-0.97). Interviews suggested that self-efficacy, access to chiropractic services, opioid stigma, and treatment impact were influencing factors. CONCLUSION: Patients with noncancer spinal pain who received chiropractic care were less likely to obtain a prescription for opioids than patients who did not receive chiropractic care.

Risk of bias in chiropractic mixed methods research: a secondary analysis of a meta-epidemiological review.

Objective: To examine the risk of bias in chiropractic mixed methods research. Methods: We performed a secondary analysis of a meta-epidemiological review of chiropractic mixed methods studies. We assessed risk of bias with the Mixed Methods Appraisal Tool (MMAT) and used generalized estimating equations to explore factors associated with risk of bias. Results: Among 55 eligible studies, a mean of 62% (6.8 [2.3]/11) of MMAT items were fulfilled. In our adjusted analysis, studies published since 2010 versus pre-2010 (adjusted odds ratio [aOR] = 2.26; 95% confidence interval [CI], 1.39 to 3.68) and those published in journals with an impact factor versus no impact factor (aOR = 2.21; 95% CI, 1.33 to 3.68) were associated with lower risk of bias. Conclusion: Our findings suggest opportunities for improvement in the quality of conduct among published chiropractic mixed methods studies. Author compliance with the MMAT criteria may reduce methodological bias in future mixed methods research.

Objectif: examiner le risque de biais dans la recherche sur les méthodes mixtes chiropratiques. Méthodologie: nous avons effectué une analyse secondaire d'un examen méta-épidémiologique d'études de méthodes mixtes chiropratiques. Nous avons examiné le risque de biais avec The Mixed Methods Appraisal Tool, MMAT (l'outil d'évaluation des méthodes mixtes), et utilisé des équations d'estimation généralisées pour explorer les facteurs associés au risque de biais. Résultats: parmi 55 études admissibles, une moyenne de 62 % (6,8 [2,3]/11) des items du MMAT ont été remplis. Dans notre analyse ajustée, les études publiées depuis 2010 versus celles d'avant 2010 (rapport de cotes [aOR] ajusté = 2,26; intervalle de confiance [IC] à 95 %, 1,39 à 3,68), et celles publiées dans des revues avec un indice de citations versus aucun indice de citations (aOR = 2,21; IC à 95 %, 1,33 à 3,68) étaient associées à un risque de biais plus faible. Conclusion: nos résultats suggèrent des opportunités d'amélioration de la qualité de la conduite parmi les études publiées sur les méthodes mixtes chiropratiques. La conformité des auteurs aux critères MMAT peut réduire les biais méthodologiques dans les futures recherches sur les méthodes mixtes.

Association of chiropractic integration in an Ontario community health centre with prescription opioid use for chronic non-cancer pain: a mixed methods study protocol.

INTRODUCTION: Emerging evidence from a number of primary care centres suggests that integration of chiropractic services into chronic pain management is associated with improved clinical outcomes and high patient satisfaction as well as with reductions in physician visits, specialist referrals use of advanced imaging and prescribing of analgesics. However, formal assessments of the integration of chiropractic services into primary care settings are sparse, and the impact of such integration on prescription opioid use in chronic pain management remains uncertain. To help address this knowledge gap, we will conduct a mixed methods health service evaluation of an integrated chiropractic back pain programme in an urban community health centre in Ontario, Canada. This centre provides services to vulnerable populations with high unemployment rates, multiple comorbidities and musculoskeletal disorders that are commonly managed with prescription opioids. METHODS AND ANALYSIS: We will use a sequential explanatory mixed methods design, which consists of a quantitative phase followed by a qualitative phase. In the quantitative phase, we will conduct a retrospective chart review and evaluate whether receipt of chiropractic services is associated with reduced opioid use among patients already prescribed opioid therapy for chronic pain. We will measure opioid prescriptions (ie, opioid fills, number of refills and dosages) by reviewing electronic medical records of recipients and non-recipients of chiropractic services between 1 January 2014 and 31 December 2020 and use multivariable regression analysis to examine the association. In the qualitative phase, we will conduct in-depth, one-on-one interviews of patients and their general practitioners to explore perceptions of chiropractic integration and its impact on opioid use. ETHICS AND DISSEMINATION: This study was approved by the Hamilton Integrated Research Ethics Board at McMaster University (approval number 2021-10930). The results will be disseminated via peer-reviewed publications, conference presentations and in-person or webinar presentations to community members and healthcare professionals.

Quality of reporting in chiropractic mixed methods research: a methodological review protocol.

BACKGROUND: Mixed methods designs are increasingly used in health care research to enrich findings. However, little is known about the frequency of use of this methodology in chiropractic research, or the quality of reporting among chiropractic studies using mixed methods. OBJECTIVE: To quantify the use and quality of mixed methods in chiropractic research, and explore the association of study characteristics (e.g., authorship, expertise, journal impact factor, country and year of publication) with reporting quality. METHODS: We will conduct a systematic search of MEDLINE, EMBASE, CINAHL, and the Index to Chiropractic Literature to identify all chiropractic mixed methods studies published from inception of each database to December 31, 2020. Articles reporting the use of both qualitative and quantitative methods, or mixed qualitative methods, will be included. Pairs of reviewers will perform article screening, data extraction, risk of bias with the Mixed Methods Appraisal Tool (MMAT), and appraisal of reporting quality using the Good Reporting of A Mixed Methods Study (GRAMMS) guideline. We will explore the correlation between GRAMMS and MMAT scores, and construct generalized estimating equations to explore factors associated with reporting quality. DISCUSSION: This will be the first methodological review to examine the reporting quality of published mixed methods studies involving chiropractic research. The results of our review will inform opportunities to improve reporting in chiropractic mixed methods studies. Our results will be disseminated in a peer-reviewed publication and presented publicly at conferences and as part of a doctoral thesis.

Attitudes, beliefs, and practices among Swiss chiropractors regarding medication prescribing for musculoskeletal conditions: a national Q-methodology study.

BACKGROUND: Swiss chiropractors have been licensed since 1995 to prescribe from a limited formulary of medications for treating musculoskeletal (MSK) conditions. In January 2018, this formulary was expanded to include additional muscle relaxant, analgesic, and anti-inflammatory medications. Internationally, controversy remains over whether or not medication prescribing should be pursued within the chiropractic profession. OBJECTIVE: The purpose of this study was to assess Swiss chiropractors' attitudes, beliefs, and practices regarding their existing medication prescription privileges. This information will provide new insights on the topic and help inform research and policy discussions about expanding chiropractic prescription rights in other jurisdictions. METHODS: A 13-item questionnaire and Q-methodology approach were used to conduct the assessment. Recruitment was conducted by e-mail between December 2019 and February 2020, and all members of the Swiss Chiropractic Association were eligible to participate. Data were analyzed using by-person factor analysis and descriptive statistics. RESULTS: In total, 187 Swiss chiropractors participated in this study (65.4% response rate). Respondents reported prescribing analgesics, anti-inflammatories, and muscle relaxants to a median of 5, 5, and 0% of patients, respectively. Forty-two percent of respondents expressed interest in further expanding the range of current medications available to Swiss chiropractors for treating MSK conditions. Only 15% expressed interest in expanding this range to include medications for treating non-MSK conditions. In the Q-methodology analysis, four salient viewpoints/groups regarding medication prescribing emerged: prescribers, non-prescribers, collaborators, and integrators. All except non-prescribers thought medication prescription privileges were advantageous for the chiropractic profession in Switzerland. There was also strong consensus among all four groups that medication prescribing should not replace manual therapy in chiropractic practice. CONCLUSION: This was the first national survey on attitudes toward prescribing medications among Swiss chiropractors since the year 2000, and the first using Q-methodology. With this approach, four unique groups of chiropractic prescribers were identified. Even with diversity among clinicians, the findings of this study showed general support for, along with conservative use of, prescribing privileges within the Swiss chiropractic profession. Studies in jurisdictions outside of Switzerland are needed to assess whether chiropractors are interested in expanding their scopes of practice to include similar prescribing privileges.

Attitudes, beliefs, and practices regarding medication prescribing for musculoskeletal conditions: a protocol for a national Q-methodology study of Swiss chiropractors.

BACKGROUND: Since 1995, chiropractors in Switzerland have been licensed to prescribe medications for treating musculoskeletal conditions. However, controversy remains over whether or not medication prescribing should be pursued within the chiropractic profession internationally. OBJECTIVE: To assess Swiss chiropractors' attitudes, beliefs, and practices regarding their existing medication prescription privileges. METHODS: A Q-methodology approach will be used to collect data for the assessment. In addition, scope expansion and frequency of prescribing by Swiss chiropractors will be queried using a 13-item questionnaire. Recruitment will be conducted by e-mail and all members of the Swiss Chiropractic Association will be eligible to participate. Data will be analyzed using by-person factor analysis and descriptive statistics. DISCUSSION: This will be the first national update on attitudes toward prescribing medications among Swiss chiropractors since 2003, and the first using Q-methodology. The results of this study are important as they will inform future directions and research regarding chiropractic prescription rights.

CONTEXTE: En Suisse, depuis 1995, les chiropraticiens sont autorisés à prescrire des médicaments pour traiter des affections musculosquelettiques. Cependant, la prescription de médicaments par les chiropraticiens à l'échelle internationale fait toujours l'objet d'une controverse. OBJECTIF: Évaluer les attitudes, les croyances et les pratiques des chiropraticiens suisses en ce qui concerne leur droit actuel de prescrire des médicaments. MÉTHODOLOGIE: Une méthodologie Q sera utilisée pour recueillir les données nécessaires à l'étude. En outre, l'élargissement du champ de pratique et la fréquence de prescription chez les chiropraticiens suisses seront étudiés à l'aide d'un questionnaire comprenant 13 questions. Le recrutement sera effectué par courriel et tous les membres de l'Association suisse chiropratique pourront participer à l'étude. Les données seront analysées par une analyse de facteurs personnels et par statistique descriptive. DISCUSSION: Il s'agira de la première mise à jour nationale sur les attitudes des chiropraticiens suisses à l'égard de leur droit de prescrire des médicaments depuis 2003, et la première étude à utiliser la méthode Q. Les résultats sont importants car ils permettront d'éclairer les orientations et les recherches futures sur le droit de prescrire des chiropraticiens.

Exposure to a motor vehicle collision and the risk of future back pain: A systematic review and meta-analysis.

OBJECTIVE: The purpose of this study is to summarize the evidence for the association between exposure to a motor vehicle collision (MVC) and future low back pain (LBP). LITERATURE SURVEY: Persistent low back pain (LBP) is a relatively common complaint after acute injury in a MVC, with a reported 1 year post-crash prevalence of at least 31 % of exposed individuals. Interpretation of this finding is challenging given the high incidence of LBP in the general population that is not exposed to a MVC. Risk studies with comparison control groups need to be examined in a systematic review. METHODOLOGY: A systematic search of five electronic databases from 1998 to 2019 was performed. Eligible studies describing exposure to a MVC and risk of future non-specific LBP were critically appraised using the Quality in Prognosis Studies (QUIPS) instrument. The results were summarized using best-evidence synthesis principles, a random effects meta-analysis and testing for publication bias. SYNTHESIS: The search strategy yielded 1136 articles, three of which were found to be at low to medium risk of bias after critical appraisal. All three studies reported a positive association between an acute injury in a MVC and future LBP. Pooled analysis of the results resulted in an unadjusted relative risk of future LBP in the MVC-exposed and injured population versus the non-exposed population of 2.7 (95 % CI [1.9, 3.8]), which equates to a 63 % attributable risk under the exposed. CONCLUSIONS: There was a consistent positive association in the critically reviewed literature that investigated the risk of future LBP following an acute MVC-related injury. For the patient with chronic low back pain who was initially injured in a MVC, more often than not (63 % of the time) the condition was caused by the MVC. These findings are likely to be of interest to clinicians, insurers, patients, governments and the courts. Future studies from both general and clinical populations would help strengthen these results.

Chiropractic integration within a community health centre: a cost description and partial analysis of cost-utility from the perspective of the institution.

OBJECTIVE: To evaluate costs and consequences of a new back pain service provided by chiropractors integrated into a Community Health Centre in Cambridge, Ontario. The study sample included 95 consecutive patients presenting between January 2014 to January 2016 with a mixture of sub-acute and chronic back pain. METHODS: A secondary cost-utility analysis was performed and conducted from the perspective of the healthcare institution. Cost-utility was calculated as cost per quality-adjusted life year (QALY) gained over a time horizon of 90 days. RESULTS: According to the EuroQol 5 Domain questionnaire, nearly 70% of patients improved. The mean number of treatment sessions was 8.4, and an average of 0.21 QALYs were gained at an average cost per QALY of $1,042. Seventy-seven percent of patients did not visit their primary care provider over the 90-day period, representing potential cost savings to the institution of between $2,022.23 and $6,135.82. CONCLUSION: Adding chiropractic care to usual medical care was associated with improved outcomes at a reasonable cost in a sample of complex patients with sub-acute and chronic back pain. Future comparative cost-effectiveness studies are needed.

OBJECTIF: Évaluer les coûts et les conséquences d'un nouveau service pour soulager les maux de dos offert par des chiropraticiens intégrés à un centre de santé communautaire à Cambridge, en Ontario. L'échantillon de l'étude comprenait 95 patients qui se sont présentés consécutivement entre janvier 2014 et janvier 2016 et qui étaient atteints de diverses douleurs dorsales subaiguës et chroniques. MÉTHODES: Une analyse coût-utilité secondaire a été effectuée du point de vue de l'établissement de santé. Le coût-utilité a été calculé en tant que coût par année de vie ajustée en fonction de la qualité (AVAQ) obtenu sur une période de 90 jours. RÉSULTATS: Selon les résultats du questionnaire EuroQol 5 Domain, près de 70 % des patients ont observé une amélioration de leurs symptômes. Le nombre moyen de séances de traitement était de 8,4 et une moyenne de 0,21 AVAQ a été obtenue à un coût moyen par AVAQ de 1 042 $. Soixante-dix-sept pour cent des patients n'ont pas consulté leur fournisseur de soins primaires au cours de la période de 90 jours, ce qui représente des économies potentielles de l'ordre de 2 022,23 $ à 6 135,82 $ pour l'établissement. CONCLUSION: L'ajout de soins chiropratiques aux soins médicaux habituels a entraîné une amélioration des résultats à un coût raisonnable pour un échantillon de patients ayant des besoins complexes et présentant des douleurs dorsales subaiguës et chroniques. De futures études comparatives coût-efficacité sont nécessaires.

Exposure to a Motor Vehicle Collision and the Risk of Future Neck Pain: A Systematic Review and Meta-Analysis.

OBJECTIVE: To summarize the literature that has examined the association between a motor vehicle collision (MVC) related neck injury and future neck pain (NP) in comparison with the population that has not been exposed to neck injury from an MVC. LITERATURE SURVEY: Neck injury resulting from an MVC is associated with a high rate of chronicity. Prognosis studies indicate 50% of injured people continue to experience NP a year after the collision. This is difficult to interpret due to the high prevalence of NP in the general population. METHODOLOGY: We performed a systematic review of the literature using five electronic databases, searching for risk studies on exposure to an MVC and future NP published from 1998 to 2018. The outcome of interest was future NP. Eligible risk studies were critically appraised using the modified Quality in Prognosis Studies (QUIPS) instrument. The results were summarized using best-evidence synthesis principles, a random effects meta-analysis, metaregression, and testing for publication bias was performed with the pooled data. SYNTHESIS: Eight articles were identified of which seven were of lower risk of bias. Six studies reported a positive association between a neck injury in an MVC and future NP compared to those without a neck injury in an MVC. Pooled analysis of the six studies indicated an unadjusted relative risk of future NP in the MVC exposed population with neck injury of 2.3 (95% CI [1.8, 3.1]), which equates to a 57% attributable risk under the exposed. In two studies where exposed participants were either not injured or injury status was unknown, there was no increased risk of future NP. CONCLUSIONS: There was a consistent positive association among studies that have examined the association between MVC-related neck injury and future NP. These findings are of potential interest to clinicians, insurers, patients, governmental agencies, and the courts. LEVEL OF EVIDENCE: I.

Attitudes Toward Medication Prescription Rights: A Survey of Chiropractic Students and Faculty at D'Youville College.

OBJECTIVE: The purpose of this study was to ascertain the general attitudes of students and faculty in the chiropractic department of D'Youville College, Buffalo, New York, toward the inclusion of medication prescription rights in the chiropractic scope of practice. METHODS: A 15-item questionnaire was adapted from a previous instrument used in assessing chiropractors' opinions toward medication prescription rights. Invitations were sent by e-mail to all 123 chiropractic students and faculty at D'Youville College in September 2018. Data were collected and analyzed using descriptive and inferential statistics. RESULTS: A total of 113 questionnaires were completed for a 92% response rate. Ninety percent of respondents agreed that chiropractors should be authorized to prescribe medications such as over-the-counter and prescription-based analgesics, anti-inflammatories, and muscle relaxants. Respondents were less in favor of chiropractors prescribing opioids or having full prescribing rights. Over half indicated that their knowledge of musculoskeletal medications was high, whereas a similar number indicated that their knowledge of nonmusculoskeletal medications was low. Most respondents indicated that further education in pharmacology should be necessary for those in the profession wishing to prescribe medications. CONCLUSION: Chiropractic students and faculty at D'Youville College endorsed expanding the chiropractic scope of practice to include limited medication prescription. Surveys and qualitative studies of students and faculty from other chiropractic educational institutions are warranted.

Management of Back Pain-related Disorders in a Community With Limited Access to Health Care Services: A Description of Integration of Chiropractors as Service Providers.

OBJECTIVE: The purpose of this study was to evaluate a chiropractic service for back pain patients integrated within a publicly funded, multidisciplinary, primary care community health center in Cambridge, Ontario, Canada. METHODS: Patients consulting for back pain of any duration were referred by their medical doctor or nurse practitioner for chiropractic treatment at the community health center. Patients completed questionnaires at baseline and at discharge from the service. Data were collected prospectively on consecutive patients between January 2014 and January 2016. RESULTS: Questionnaire data were obtained from 93 patients. The mean age of the sample was 49.0 ± 16.27 years, and 66% were unemployed. More than three-quarters (77%) had had their back pain for more than a month, and 68% described it as constant. According to the Bournemouth Questionnaire, Bothersomeness, and global improvement scales, a majority (63%, 74%, and 93%, respectively) reported improvement at discharge, and most (82%) reported a significant reduction in pain medication. More than three-quarters (77%) did not visit their primary care provider while under chiropractic care, and almost all (93%) were satisfied with the service. According to the EuroQol 5 Domain questionnaire, more than one-third of patients (39%) also reported improvement in their general health state at discharge. CONCLUSION: Implementation of an integrated chiropractic service was associated with high levels of improvement and patient satisfaction in a sample of patients of low socioeconomic status with subacute and chronic back pain.

High-grade spondylolytic spondylolisthesis.

Case reports of high-grade spondylolisthesis have been rarely published in the chiropractic literature. Documented here is a case involving a 28-year-old woman who presented to the World Spine Care clinic in the Dominican Republic with minimal neuromusculoskeletal symptoms despite a grade 4 spondylolytic spondylolisthesis. The key imaging and etiological features of this clinical disorder are presented.

Il y a eu peu d'études de cas de spondylolisthésis de haut degré publiées dans la littérature chiropratique. On consigne ici un cas concernant une femme de 28 ans qui s'est présentée à la clinique World Spine Care en République dominicaine avec des symptômes neuro-musculo-squelettiques minimaux malgré un spondylolisthésis spondylolytique de stade 4. Les principales caractéristiques d'imagerie et d'étiologie de ce trouble clinique sont présentées.

A rare case of Eagle syndrome and diffuse idiopathic skeletal hyperostosis in the cervical spine.

Published case studies involving diffuse idiopathic skeletal hyperostosis (DISH) along with symptomatic ossification of the stylohyoid ligament, or "Eagle syndrome," are rare. In this report, we document a case of bilateral Eagle syndrome and advanced DISH in the cervical spine of an 80-year-old man who presented with severe neck stiffness and intermittent asphyxia. The key imaging and clinical features of this disorder are also described.

Les études de cas publiées concernant l'hyperostose squelettique idiopathique diffuse (HSID) avec une ossification symptomatique du ligament stylohyoïdien, ou « syndrome d'Eagle ¼, sont rares. Dans le présent rapport, nous consignons un cas de syndrome d'Eagle bilatéral et de HSID avancée du rachis cervical chez un homme de 80 ans présentant une raideur grave de la nuque et une asphyxie intermittente. Les principales caractéristiques d'imagerie et cliniques de ce trouble sont également présentées.

Grade V acromioclavicular joint separation in a 57-year-old mountain biker.

Patients rarely present to a chiropractic office setting during the acute stage of a high-grade (i.e. Rockwood types IV-VI) separation of the acromioclavicular (AC) joint. Moreover, such cases are non-existent in the peer-reviewed chiropractic literature. Some controversy exists over the optimal (surgical vs. non-surgical) treatment of severe AC joint injuries. Published reports of nonoperative management for grade V injuries of the AC joint are also scarce. This case review highlights the plain film imaging and conservative management of a 57-year-old patient diagnosed with an acute Rockwood type V AC joint separation. Radiographs with nine years of follow-up are presented.

Les patients se présentent rarement à une clinique de chiropratique pendant la phase aiguë d'une séparation de haut grade (c.-à-d., types IV à VI de Rockwood) de l'articulation acromio-claviculaire(AC). En outre, ces cas n'existent pas dans la littérature sur la chiropratique examinée par les pairs. Le traitement optimal (chirurgical vs non chirurgical) des lésions graves de l'articulation AC ne fait pas l'unanimité. Les rapports publiés sur la prise en charge non chirurgicale des lésions de grade V de l'articulation AC sont également peu abondants. Cet examen de cas met en lumière l'imagerie par radiographie et la prise en charge conservatrice d'un patient de 57 ans souffrant de séparation aiguë de l'articulation AC de type V de Rockwood. Les radiographies avec neuf ans de suivi sont présentées.

Advanced hip joint degeneration associated with femoroacetabular impingement in a retired chiropractor.

Femoroacetabular impingement is a relatively new clinical entity only recently described in the orthopedic literature. In this report, we document a severe case of hip joint osteoarthritis associated with cam-type impingement in a retired chiropractor.

Le conflit fémoro-acétabulaire est une entité clinique relativement nouvelle, récemment décrite dans les revues orthopédiques. Dans ce rapport, nous documentons un cas grave d'arthrose de l'articulation de la hanche associée à un conflit de type à came chez un chiropraticien à la retraite.

Sciatic neuralgia associated with a perineural (Tarlov) cyst.

Perineural (Tarlov) cysts are rare and are usually asymptomatic and an incidental finding on routine spinal imaging. Presented here is a case of sciatic neuralgia in a 56-year-old patient whose clinical symptoms correlated with a lower lumbar perineural cyst.

Les kystes périneuraux (Tarlov) sont rares, et sont généralement asymptomatiques et une observation fortuite d'une imagerie routine de la colonne. Nous présentons ici un cas de névralgie sciatique chez un patient de 56 ans dont les symptômes cliniques correspondaient à un kyste périneural lombaire.
