Abstract: A technology enhanced learning and teaching (TELT) solution, radiological anatomy (RA) eLearning, composed of a range of identification-based and guided learning activities related to normal and pathological X-ray images, was devised for the Year 1 nervous and locomotor course at the Faculty of Medicine, University of South ton. Its effectiveness was evaluated using a questionnaire, pre- and post-tests, focus groups, summative assessment, and tracking data. Since introduced in 2009, a total of 781 students have used RA eLearning, and among them 167 Year 1 students in 2011, of whom 116 participated in the evaluation study. Students enjoyed learning (77%) with RA eLearning, found it was easy to use (81%) and actively engaged them in their learning (75%), all of which were associated to the usability, learning design of the TELT solution and its integration in the curriculum 80% of students reported RA eLearning helped their revision of anatomy and 69% stated that it facilitated their application of anatomy in a clinical context, both of which were associated with the benefits offered by the learning and activities design. At the end of course summative assessment, student knowledge of RA eLearning relevant topics (mean 80% SD ±16) was significantly better as compared to topics not relevant to RA eLearning (mean 63% SD ±15) (mean difference 18% 95% CI 15% to 20% P < 0.001). A well designed and integrated TELT solution can be an efficient method for facilitating the application, integration, and contextualization of anatomy and radiology to create a blended learning environment.

Abstract: This article was migrated. The article was marked as recommended. The COVID-19 pandemic has resulted in a massive adaptation in health professions education, with a shift from in-person learning activities to a sudden heavy reliance on internet-mediated education. Some health professions schools will have already had considerable educational technology and cultural infrastructure in place, making such a shift more of a different emphasis in provision. For others, this shift will have been a considerable dislocation for both educators and learners in the provision of education.To aid educators make this shift effectively, this 12 Tips article presents a compendium of key principles and practical recommendations that apply to the modalities that make up online learning. The emphasis is on design features that can be rapidly implemented and optimised for the current pandemic. Where applicable, we have pointed out how these short-term shifts can also be beneficial for the long-term integration of educational technology into the organisations' infrastructure.The need for adaptability on the part of educators and learners is an important over-arching theme. By demonstrating these core values of the health professions school in a time of crisis, the manner in which the shift to online learning is carried out sends its own important message to novice health professionals who are in the process of developing their professional identities as learners and as clinicians.

Abstract: Characterization of the oropharynx, a sub ision of the pharynx between the soft palate and the epiglottis, is limited to simple measurements. Structural changes in the oropharynx in whiplash‐associated disorder (WAD) cohorts have been quantified using two‐dimensional (2D) and three‐dimensional (3D) measures but the results are inconsistent. Statistical shape modelling (SSM) may be a more useful tool for systematically comparing morphometric features between cohorts. This technique has been used to quantify the variability in boney and soft tissue structures, but has not been used to examine a hollow cavity such as the oropharynx. The primary aim of this project was to examine the utility of SSM for comparing the oropharynx between WAD cohorts and control and WAD severity cohorts. The secondary aim was to determine whether shape is associated with sex, height, weight and neck length. Magnetic resonance (MR) T1‐weighted images were obtained from healthy control ( n = 20), acute WAD ( n = 14) and chronic WAD ( n = 14) participants aged 18–39 years. Demographic, WAD severity (neck disability index) and body morphometry data were collected from each participant. Manual segmentation of the oropharynx was undertaken by blinded researchers between the top of the soft palate and tip of the epiglottis. Digital 3D oropharynx models were constructed from the segmented images and principal component (PC) analysis was performed with the PC weights normalized to z‐scores for consistency. Statistical analyses were undertaken using multivariate linear models. In the first statistical model the independent variable was group (acute WAD, chronic WAD, control) and in the second model the independent variable was WAD severity (recovered/mild, moderate/severe). The covariates for both models included height, weight, average neck length and sex. Shape models were constructed to visualize the effect of perturbing these covariates for each relevant mode. The shape model revealed five modes which explained 90% of the variance: mode 1 explained 59% of the variance and primarily described differences in isometric size of the oropharynx, including elongation mode 2 (13%) primarily described lateral (width) and AP (depth) dimensions mode 3 (8%) described retroglossal AP dimension mode 4 (6%) described lateral dimensions at the retropalatal‐retroglossal junction and mode 5 (4%) described the lateral dimension at the inferior retroglossal region. There was no difference in shape (mode 1 p = 0.52 mode 2 p = 0.96 mode 3 p = 0.07 mode 4 p = 0.54 mode 5 p = 0.74) between control, acute WAD and chronic WAD groups. There were no statistical differences for any mode (mode 1 p = 0.12 mode 2 p = 0.29 mode 3 p = 0.56 mode 4 p = 0.99 mode 5 p = 0.96) between recovered/mild and moderate/severe WAD. Sex was not significant in any of the models but for mode 1 there was a significant association with height ( p = 0.007), mode 2 neck length ( p = 0.044) and in mode 3 weight ( p = 0.027). Although SSM did not detect differences between WAD cohorts, it did detect associations with body morphology indicating that it may be a useful tool for examining differences in the oropharynx.

Abstract: Research involving chiropractors is evolving and expanding in Europe while resources are limited. Therefore, we considered it timely to initiate a research agenda for the chiropractic profession in Europe. The aim was to identify and suggest priorities for future research in order to best channel the available resources and facilitate advancement of the profession. In total, 60 academics and clinicians working in a chiropractic setting, and who had attended any of the annual European Chiropractors’ Union/European Academy of Chiropractic (ECU/EAC) Researchers’ Day meetings since their inception in 2008, were invited to participate. Data collection consisted of the following phases: phase 1 identification of themes phase 2 consensus, which employed a Delphi process and allowed us to distill the list of research priorities and phase 3 presentation of the results during both the Researchers’ Day and a plenary session of the annual ECU Convention in May 2013. In addition, results were distributed to all ECU member countries. The response rate was 42% from phase 1 and 68% from phase 2. In general, participants were middle-aged, male and had been awarded a Doctor of Philosophy (PhD) as well as chiropractic degree. Approximately equal numbers of participants had obtained their chiropractic degree from the UK/Europe and North America. The majority of participants worked primarily in an academic/research environment and approximately half worked in an independent institution. In total, 58% of the participants were from the UK and Denmark, collectively representing 44% of the chiropractors working in Europe. In total, 70 research priorities were identified, of which 19 reached consensus as priorities for future research. The following three items were thought to be most important: 1) cost-effectiveness/economic evaluations, 2) identification of subgroups likely to respond to treatment, and 3) initiation and promotion of collaborative research activities. This is the first formal and systematic attempt to develop a research agenda for the chiropractic profession in Europe. Future discussion and study is necessary to determine whether the themes identified in this survey should be broadly implemented.

Abstract: Knowledge of musculoskeletal anatomy is fundamental to physical therapy education. Although detailed anatomy syllabi have been developed for medical and other health professional students, none are available for training physical therapists. Therefore, the aim of this project was to produce a core musculoskeletal anatomy syllabus specific to physical therapy students, utilizing a modified Delphi approach. An international Delphi panel ( n = 53) composed of anatomists and clinicians involved in physical therapy education considered a total of 2193 anatomical items arranged in four categories (musculoskeletal concepts vertebral column pectoral girdle and upper limb pelvic girdle and lower limb). Using specific criteria, items were rated on the basis of whether they were considered essential knowledge for a competent physical therapy student, and were categorized as core, recommended, not recommended or not core. Of the 2193 items, 1700 (77.5%) were rated as core or recommended. For musculoskeletal concepts, 70% (233/332) of items were categorized as core/recommended. Approximately 80% of items in the other three categories were considered core/recommended—vertebral column (355/440), pectoral girdle and upper limb (513/657), and pelvic girdle and lower limb (599/764). This project presents a detailed musculoskeletal anatomy syllabus which may be used within a physical therapy curriculum. A key difference compared to published musculoskeletal anatomy syllabi for medical students is that a greater number of items are considered core/recommended (approximately 80% vs. 50%). These findings will now be considered and deliberated in accordance with the International Federation of Associations of Anatomists modified Delphi approach.

Abstract: The study of human anatomy is fundamental to medical education globally. Knowledge of musculoskeletal anatomy is essential for safe and effective clinical practice, yet this topic often receives insufficient medical program time and perceptions differ regarding which knowledge is core. Given the lack of syllabuses specific to musculoskeletal anatomy, this article aims to provide a detailed syllabus for the vertebral column and limbs relevant to medical students. A Delphi panel comprising anatomists and clinicians rated 2,260 anatomical structures and concepts as "essential," "important," "acceptable," or "not required," with evaluations based around the core knowledge deemed acceptable for a competent medical student. Based on the percentage of panelist agreement for an item to be considered "essential," each item was then classified as core (≥60%), recommended (30%-59%), not recommended (20%-29%), or not core (<20%). Items not classified as core or recommended but rated important by greater than 50% of the panel were highlighted for future consideration. A total of 252/389 musculoskeletal concept items were categorized as core or recommended. The number of core or recommended items for the vertebral column, upper limb, and lower limb were 220/438, 322/663, and 318/770, respectively. Ninety-six items were recommended for future consideration. The results of this Delphi panel will be published on the International Federation of Associations of Anatomists website for continuing international consideration and deliberation by relevant stakeholders. The aim is to set an internationally recognized syllabus, that covers the minimum musculoskeletal content that is academically and clinically relevant. Clin.

Abstract: Accessory attachments of the levator scapulae (LS) muscle have been described in the literature in previous cadaveric studies, but there is little knowledge about the incidence and distribution. Knowledge of LS accessory attachments is relevant to clinicians working in the fields of radiology, surgery, neurology, and musculoskeletal medicine. The purpose of this study was to explore the incidence and spectrum of LS caudal accessory attachments in vivo using magnetic resonance (MR) imaging in a young cohort. MR images of the cervical spine were obtained from 37 subjects (13 males and 24 females) aged 18-36 years using an axial T1-weighted spin echo sequence acquired from a 3-Tesla MR scanner. The LS muscle was identified, and the presence of caudal accessory attachments was recorded and described. LS caudal accessory attachments were identified in 16 subjects (4 right, 6 left, and 6 bilateral 12 female). Ten had unilateral accessory attachments to the serratus anterior, serratus posterior superior or the first/second rib. Four had bilateral accessory attachments to serratus anterior. One had bilateral accessory attachments to serratus posterior superior and unilateral accessory attachment to serratus anterior. One had bilateral attachments to both muscles. Both unilateral and bilateral LS caudal accessory attachments were present in nearly half of the subjects examined. They were relatively more frequent in females than males. The findings indicate that these accessory attachments are common, and in some cases, those accessory attachments can occur bilaterally and to more than one site.

Abstract: There is uncertainty regarding the clinical significance of findings on MRI in patients with whiplash associated disorder (WAD) or nonspecific neck pain (NSNP). To compare the presence of cervical spine MRI findings in people with WAD or NSNP with pain-free controls. Systematic review and meta-analysis. Adults with WAD (n = 994), NSNP (n = 715), or pain-free controls (n = 2323). 0.5T, 1.5T, and 3.0T. Medline, EMBASE, CINAHL, Web of Science, SCOPUS, and Cochrane CENTRAL databases were searched. Two independent reviewers identified studies for inclusion and extracted data. Risk of bias was assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Overall quality of the evidence from meta-analysis was assessed using the Grades of Recommendation, Assessment, Development, and Evaluation approach. Meta-analysis was performed using a random-effects model to calculate odds ratios or standard mean differences (SMDs) for binary and continuous data. In total, 31 studies were included (eight comparing acute WAD to controls, 14 comparing chronic WAD to controls, 12 comparing chronic NSNP to controls) comprising 4032 participants. Rectus capitis posterior major cross-sectional area was smaller in people with chronic NSNP than controls (two studies: SMD -1.18 [95% confidence interval [CI] -1.65, -0.71]). The remaining meta-analysis comparisons showed no group differences in MRI findings. The quality of evidence was mostly low due to small s le sizes and high heterogeneity. Given the typically low-quality evidence, definitive conclusions cannot be drawn on the presence of MRI findings in in iduals with WAD or NSNP compared with pain-free controls. 3 Technical Efficacy: Stage 3 J.

Abstract: While debate about the use of—and alternatives to—human cadaveric dissection in medical training is robust, little attention has been paid to questions about timing. This study explores the perspectives of medical students and recent graduates with regard to two key questions: when in the degree program do students prefer dissection opportunities and what are the students getting out of participating in dissection? Self‐report survey data from students in preclinical years ( n = 105), clinical years ( n = 57), and graduates ( n = 13) were analyzed. Most (89%) preferred dissection during the preclinical years, with no effect by training year ( χ 2 = 1.98, p = 0.16), previous anatomy ( χ 2 = 3.64, p = 0.31), or dissection ( χ 2 = 3.84, p = 0.26) experience. Three key findings emerged. First, the majority of students prefer to dissect in the preclinical years because they view dissection as important for developing foundation knowledge and delivering an opportunity for consolidation prior to transitioning to primarily clinical studies. In addition, students recognize that it is a time‐consuming activity requiring specialized facilities. Second, three main understandings of the purpose of dissection were reported: depth of learning, learning experience, and real‐world equivalence. Third, these student perspectives of the purpose of dissection are associated with timing preferences for dissection opportunities. The results identify the preclinical phase as the optimal time to strategically integrate dissection into medical training in order to maximize the benefits of this unique learning opportunity for students and minimize its impact upon curricular time.

Abstract: Teaching internal structures obscured from direct view is a major challenge of anatomy education. High-fidelity interactive three-dimensional (3D) micro-computed tomography (CT) models with virtual dissection present a possible solution. However, their utility for teaching complex internal structures of the human body is unclear. The purpose of this study was to investigate the use of a realistic 3D micro-CT interactive visualization computer model to teach paranasal sinus anatomy in a laboratory setting during pre-clinical medical training. Year 1 (n = 79) and Year 2 (n = 59) medical students undertook self-directed activities focused on paranasal sinus anatomy in one of two laboratories (traditional laboratory and 3D model). All participants completed pre and posttests before and after the laboratory session. Results of regression analyses predicting post-laboratory knowledge indicate that, when students were inexperienced with the 3D computer technology, use of the model was detrimental to learning for students with greater prior knowledge of the relevant anatomy (P < 0.05). For participants experienced with the 3D computer technology, however, the use of the model was detrimental for students with less prior knowledge of the relevant anatomy (P < 0.001). These results emphasize that several factors need to be considered in the design and effective implementation of such models in the classroom. Under the right conditions, the 3D model is equal to traditional laboratory resources when used as a learning tool. This paper discusses the importance of preparatory training for students and the technical consideration necessary to successfully integrate such models into medical anatomical curricula.

Abstract: The reduced use of dissection associated with the introduction of integrated systems problem-based learning curricula, graduate-entry programs and medical school expansion is a frequent topic of discussion and debate in modern medical training. The purpose of this study was to investigate the impact of these changes to the medical education landscape, by looking at the current utilization and integration of dissection in medical schools, in Australia and New Zealand. A survey and an invitation to participate in an interview were distributed to all Australian Medical Council-accredited medical schools. Sixteen schools (76%) responded to the survey and five interviews (24%) were conducted. Dissection was a component of the medical program in 12 of the 16 schools surveyed. The opportunity for medical students to dissect human cadavers was found to be related to whether the medical school was established pre- or post-2000 (P = 0.003) but was not significantly associated to undergraduate- or graduate-entry (P = 0.64), program length (P = 0.59) or the number of commencing students (P = 0.07). The methods used for the delivery and integration of dissection varied between schools. Despite substantial changes to the delivery of anatomy in Australian and New Zealand medical schools, a variety of approaches have been adopted to ensure dissection remains an integral component of medical student education. Based on our findings, a number of recommendations were formulated to encourage the integration of dissection, regardless of the didactics of the program, to enhance the anatomical knowledge of students.

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: Impingement of the synovial fold of the distal tibiofibular joint (DTFJ) may contribute to the development of chronic ankle pain and disability after ankle inversion sprain. The morphology of the synovial fold of the DTFJ and recess is poorly understood. The purpose of this study was to describe and quantify the synovial fold and recess of the DTFJ. Thirty-three pairs of adult embalmed ankle joints were dissected and the presence, disposition, morphology, and dimensions of the synovial fold were determined in relation to the DTFJ and its recess. A synovial fold was present in all specimens examined and extended from the deep posterior tibiofibular ligament along the DTFJ line an average of 15.31 mm [standard deviation (SD), 4.42 mm]. The majority of synovial folds were elongated in shape with smooth borders and occupied more than two thirds of the DTFJ line. In 70% of ankles examined, the synovial folds were found to extend a mean of 20.05 mm (SD, 7.01 mm) from the DTFJ line into the recess where they were loosely attached to the fibular wall. In the remaining ankles, the synovial fold was limited to the DTFJ line leaving the recess devoid of a synovial fold. Intra-observer and inter-observer reliability of measurements was good to excellent (intra-class correlation coefficient, 0.61-0.99). An understanding of the morphology of the DTFJ synovial fold might help to explain ongoing ankle pain after injury, and why arthroscopic removal of the tissue might be therapeutic.

Abstract: Morphometric changes to cervical musculature in whiplash associated disorder have been reported in several studies with varying results. However, the evidence is not clear because only a limited number of cohorts have been studied and one cohort has been reported in multiple publications. The aim of this study was to assess the evidence for cervical muscle morphometric changes on magnetic resonance (MR) images after whiplash using a systematic review with meta-analysis. PubMed, MEDLINE and Cochrane Library were searched without language restriction using combinations of the MeSH terms "muscles", "whiplash injuries", and "magnetic resonance imaging". Studies of acute and chronic whiplash were included if they compared whiplash and control cervical spine muscle morphometry measurements from MR images. The search identified 380 studies. After screening, eight studies describing five cohorts (one acute, three chronic, one both acute and chronic) met the inclusion criteria. Participant characteristics and outcome measures were extracted using a standard extraction format. Quality of eligible studies was assessed using the Newcastle-Ottawa Scale. Muscle cross-sectional area (CSA) and fat infiltrate (MFI) for acute and chronic whiplash cohorts were compared using mean difference and 95% confidence intervals. Meta-analysis models were created when data from more than two eligible cohorts was available, using inverse-variance random-effects models (RevMan5 version 5.3.5). Quality assessment was uniformly good but only two studies blinded the assessor. Analysis of the acute cohorts revealed no consensus with respect to CSA. MFI was not measured in the acute cohorts. Analysis of the chronic cohorts revealed CSA is probably increased in some muscles after whiplash but there is insufficient evidence to confirm whether MFI is also increased. Because the available data were limited, meta-analyses of only multifidus were performed. In chronic whiplash multifidus CSA was significantly increased at C5 (Z = 3.51, p < 0.01) and C6 (Z = 2.66, p < 0.01) and MFI was significantly increased at C7 only (Z = 2.52, p < 0.01) but the heterogeneity was unacceptably high (I The strength of the evidence for cervical muscle morphometric changes on MR images after whiplash is inconsistent for CSA and MFI. Future study designs should be standardised with quantification of three-dimensional muscle morphometry.

Abstract: Barium sulfate and lead oxide contrast media are frequently used for cadaver-based angiography studies. These contrast media have not previously been compared to determine which is optimal for the visualisation and measurement of blood vessels. In this study, the lower limb vessels of 16 embalmed Wistar rats, and four sets of cannulae of known diameter, were injected with one of three different contrast agents (barium sulfate and resin, barium sulfate and gelatin, and lead oxide combined with milk powder). All were then scanned using micro-computed tomography (CT) angiography and 3-D reconstructions generated. The number of branching generations of the rat lower limb vessels were counted and compared between the contrast agents using ANOVA. The diameter of the contrast-filled cannulae, were measured and used to calculate the accuracy of the measurements by comparing the bias and variance of the estimates. Intra- and inter-observer reliability were calculated using intra-class correlation coefficients. There was no significant difference (mean difference [MD] 0.05 MD 95% confidence interval [CI] -0.83 to 0.93) between the number of branching generations for barium sulfate-resin and lead oxide-milk powder. Barium sulfate-resin demonstrated less bias and less variance of the estimates (MD 0.03 standard deviation [SD] 1.96 mm) compared to lead oxide-milk powder (MD 0.11 SD 1.96 mm) for measurements of contrast-filled cannulae scanned at high resolution. Barium sulfate-resin proved to be more accurate than lead oxide-milk powder for high resolution micro-CT scans and is preferred due to its non-toxicity. This technique could be applied to any embalmed specimen model. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract: Intra-articular synovial folds of the cervical spine are considered to be a potential source of neck pain and disability. The purpose of the present study was to devise and validate a method to determine the normal morphometry of the synovial folds as a basis for understanding their functional and clinical significance. Nine cadaver cervical spines were sectioned in the sagittal plane. The presence of the synovial folds at the lateral atlanto-axial joints was determined and their morphology described. Depth of projection, cross-sectional area and volume of the ventral and dorsal synovial folds of the right and left lateral atlanto-axial joints were measured from sagittal sections and compared. The relationship between synovial fold dimensions and subject age and cartilage degeneration were determined. Repeat measurements were made for the calculation of method reliability, and the water displacement method was used to determine method validity. There was a trend for ventral synovial folds to be larger than dorsal synovial folds. There was no correlation between synovial fold dimensions and age and extent of cartilage degeneration. Measurement reliability ranged from intraclass correlation coefficient 0.95-1.00 (intra-observer), 0.95-1.00 (test-retest) and 0.61-1.00 (inter-observer). Limits of agreement for the sectional and water displacement methods for the measurement of synovial fold volume were -1.04 ± 3.35 mm(3). A reliable method for quantifying synovial fold dimensions was devised. The results of this study provide a basis for the determination and diagnosis of pathologies affecting the synovial folds.

Abstract: The anatomy of the cervical spine musculature visible on magnetic resonance (MR) images is poorly described in the literature. However, the correct identification of in idual muscles is clinically important because certain conditions of the cervical spine, for ex le whiplash associated disorders, idiopathic neck pain, cervical nerve root avulsion and cervical spondylotic myelopathy, are associated with different morphological changes in specific muscles visible on MR images. Knowledge of the precise structure of different cervical spine muscles is crucial when comparisons with the contralateral side or with normal are required for accurate description of imaging pathology, management and assessment of treatment efficacy. However, learning the intricate arrangement of 27 muscles is challenging. A multi-level cross-sectional depiction combined with three-dimensional reconstructions could facilitate the understanding of this anatomically complex area. This paper presents a comprehensive series of labeled axial MR images from one in idual and serves as a reference atlas of the cervical spine musculature to guide clinicians, researchers, and anatomists in the accurate identification of these muscles on MR imaging.

Abstract: The synovial folds of the cervical spine are regarded as a potential source of neck pain and headache, especially following whiplash injury. Damage to the synovial folds following motor vehicle trauma has been well documented in post-mortem studies. However, methods of identifying injury to the synovial folds in the survivors of motor vehicle trauma have proven elusive to date. Recently, it has been made possible to image the synovial folds in vivo using magnetic resonance imaging. This now makes it feasible to investigate the potential involvement of synovial folds in the generation of neck pain and headache and its relief using spinal manipulation. This paper reviews critically the morphology of the synovial folds of the cervical spine that underpins the hypotheses proposed to explain their functional and clinical significance and a new system of naming and classifying the synovial folds is presented. Although there is some evidence to support the contribution of the synovial folds to neck pain, several theories have little or no support and require investigation and further evaluation. These findings have implications for understanding the anatomical basis of neck pain and headache and the rationale for the use of spinal manipulation in their management.
