Osteopathy has been shown to be effective in the management of chronic low back pain. Guidelines recommend biopsychosocial care for chronic, complex musculoskeletal conditions, including non-specific low back pain but there is a lack of evidence comparing standard osteopathic care, which has traditionally been based on dated and disputed biomechanical theories of dysfunction, with more contemporary biopsychosocial approaches. A multiple baseline single case experimental design trial with 11 UK osteopaths and 60 patients is currently assessing effectiveness of osteopathic treatment for patients with non-specific low back pain of more than 12 weeks’ duration. Patients are randomised to early, middle, or late treatment start dates to increase the validity of inferences about the effects of treatment. Osteopaths have participated in one course on the study protocol and processes pre-participation and will take an e-learning course on the biopsychosocial management of patients with low back pain after the first patient recruitment stage. Statistical analysis will assess the degree and rate of change between baseline, intervention and follow-up periods, and whether differences in effect are observed after the osteopaths have completed the biopsychosocial patient management training course. Primary outcomes will be the Numeric Pain Rating and Patient Specific Function Scales, measured daily at baseline and for 6 weeks during the intervention stage, and weekly or fortnightly during a 12-week follow-up period.Background

In vivo evaluation of IVD strains is crucial to better understand normal and pathological IVD mechanics, and to evaluate the effectiveness of treatments. This study aimed to 1) develop a novel in vivo technique based on 3T MRI and digital volume correlation (DVC) to measure strains within IVDs and 2) to use this technique to resolve 3D strains within IVDs of healthy volunteers during extension. This study included 40 lumbar IVDs from eight healthy subjects. The optimal MR sequence to minimise DVC uncertainties was identified by scanning one subject with four different sequences: CISS, T1VIBE, T2SPACE, and T2TSE. To assess the repeatability of the strain measurements in spines with different anatomical and morphological variations four subjects were scanned with the optimal sequence, and uncertainties of the strain measurements were quantified. Additionally, to calculate 3D strains during extension, MRIs were acquired from six subjects in both the neutral position and after full extension.Background

Cauda Equina Syndrome (CES) needs to be diagnosed and managed promptly to ensure the best outcome for patients. Our current spinal service has been centralised, with referrals currently delivered via an online system. This means that patients aren't seen by spinal specialists until confirmed radiological diagnosis. To ensure patient safety, we must make sure that our CES pathway is as robust as possible. A Google Forms questionnaire was emailed to various health professionals involved in the CES patient journey throughout the Lancashire & South Cumbria region. Participants were asked to identify problems with our current pathway and to provide possible solutions for improvement. 64 responses were received from 5 different departments throughout 6 NHS employers: 21 (33%) consultants, 6 (9%) middle grade doctors, 31 physiotherapists (48%), 3 (5%) GPs and 3 (5%) others. Many common themes were identified: the need to improve CES education to both referrers and patients (22% responses), addressing the issue of scan availability (39% responses), the need for a clearer pathway for GPs (26% responses) among others. Participants were asked to rate their confidence in the management of both suspected (mean=7.6 +/−2.3) and diagnosed CES (mean=8.0 +/− 2.0).Background
Methods & Results
Low back pain (LBP) is a common condition with substantial associated disability and costs, best understood using a biopsychosocial approach. Research demonstrates LBP beliefs are important, with biomedical beliefs influencing practitioner's management. LBP beliefs can be inconsistent amongst medical students. The aim of this study was to investigate graduate medical student's beliefs of LBP and what influences them. A cross sectional study of phase one and phase three students at the University of Warwick was conducted. Participants were recruited via voluntary response sampling. A survey investigated LBP beliefs, utilising the Back Beliefs Questionnaire (BBQ) and Health Care Providers’ Pain and Impairment Relationship Scale (HC-PAIRS). Qualitative data was collected on what influences beliefs about the causes and management of LBP, which was analysed descriptively using thematic analysis. Fifty-seven students completed the questionnaire. Median BBQ and HC-PAIRS scores were consistent between both year groups. Three main themes emerged from the qualitative data: Sources of influence, influence of personal experience and influence of medical education. Participants discussed single or multiple sources influencing their beliefs. Another main theme was the influence of experiencing LBP personally or through discussions with others. The final main theme described the influence of medical education.Purposes and background

This study aims to investigate whether bacteria are present in intervertebral discs (IVDs) and their influence. Causality between chronic infection of the IVD and its degenerative process gained great interest recently. Granville Smith Human IVD tissue was fixed in paraffin and Immunohistochemical stained for Gram-positive bacteria. NP cells in monolayer have been stimulated with LPS (0.1–50 µg/ml) and Peptidoglycan (0.1–50 µg/ml) for 24, 48 and 72 hrs to investigate their influence. The concentration of proinflammatory and catabolic cytokines in the media is being measured using ELISA. RNA extracted and RT-qPCR utilised for factors associated with disc degeneration matrix genes, matrix degrading enzymes, cytokines, neurotrophic factors and angiogenic factors.Objectives

Clinical guidelines recommend epidural steroid injection (ESI) as a treatment option for severe disc-related sciatica, but there is considerable uncertainty about its effectiveness. Currently, we know very little about factors that might be associated with good or poor outcomes from ESI. The aim of this systematic review was to synthesize and appraise the evidence investigating prognostic factors associated with outcomes following ESI for patients with imaging confirmed disc-related sciatica. The search strategy involved the electronic databases Medline, Embase, CINAHL Plus, PsycINFO and reference lists of eligible studies. Selected papers were quality appraised independently by two reviewers using the Quality in Prognosis Studies (QUIPS) tool. Between study heterogeneity precluded statistical pooling of results.Background

Spinal surgery is a high-risk surgical speciality, a patient's understanding of surgical interventions, alternative treatment options, and the benefits and risks must be ascertained to gain informed consent. This pilot study aims to evaluate if the provision of a digital recording of a patient's consultation enhances patient satisfaction, improves recall of clinical diagnosis, recall of treatment options and the risks and benefits of Spinal Surgery. A coalition team was identified. A safe and secure process for recording and storage identified. Both qualitative and quantitative data was collected via questionnaires. 62 patients were invited to participate in the pilot, 12 declined. Data was collected immediately post consultation, and two weeks following the consultation via telephone. Comparison was made of the relative increase or decrease in patient recall of the clinical diagnosis, treatment options, and the benefits and the risks of spinal surgery. Patient satisfaction was measured pre- and post- consultation. 50 patients (81%) participated. 32 participants (52%) responded to follow up questionnaire at 2 weeks. Recall of risk for surgical intervention increased by 37%, and of benefit by 36%. Patient satisfaction was rated excellent or very satisfied in 93% at initial consultation and at 2 week follow up all participant's rated satisfaction as excellent or very satisfied.Purpose of study and background
Methodology and results
Low back pain is strongly associated with degeneration of the intervertebral disc (IVD). During degeneration, altered matrix synthesis and increased matrix degradation, together with accompanied cell loss is seen particularly in the nucleus pulposus (NP). It has been proposed that notochordal (NC) cells, embryonic precursors for the cells within the NP, could be utilized for mediating IVD regeneration. However, injectable biomaterials are likely to be required to support their phenotype and viability within the degenerate IVD. Therefore, viability and phenotype of NC cells were analysed and compared within biomaterial carriers subjected to physiological oxygen conditions over a four-week period were investigated. Porcine NC cells were incorporated into three injectable hydrogels: NPgel (a L-pNIPAM-co-DMAc hydrogel), NPgel with decellularized NC-matrix powder (dNCM) and Albugel (an albumin/ hyaluronan hydrogel). The NCs and biomaterials constructs were cultured for up to four weeks under 5% oxygen (n=3 biological repeats). Histological, immunohistochemical and glycosaminoglycans (GAG) analysis were performed to investigate NC viability, phenotype and extracellular matrix synthesis and deposition.Objectives
Methodology
Advanced spinal practitioner physiotherapists (ASPPs) assess and manage spinal referrals, as advocated by the National Low Back Pain Pathway in the United Kingdom. The ASPP pathway relies on multi-disciplinary team (MDT) meetings where potential surgically appropriate or complex cases can be discussed. Meetings were held with two different Consultant Spinal Neurosurgeons (total 2 meetings per month). The aim of this service evaluation was to assess MDT meeting outcomes and surgical listing. This retrospective service evaluation used routinely collected MDT meeting documentation between May 2019 and October 2021. Data was extracted by two ASPPs, and 20% checked by a third ASPP. Extracted data included: number of patients discussed, Consultant, reason for discussion, and outcome (surgical listing or other). Data was analysed by two ASPPs using pivot tables in Microsoft Excel and was reported using counts and percentages across month and year.Background
Methods
Guidelines recommend epidural steroid injections (ESI) for treating severe disc-related sciatica based on trial data showing modest reductions in leg pain, disability and surgery avoidance. Despite their widespread use, there is no clear evidence about which patients are more likely to benefit from ESI. The aim of this study was to generate consensus on potential predictors of outcome following ESI for disc-related sciatica to include in data collection in a future cohort study. A list of potential predictors of outcome following ESI was generated from existing literature and a consensus meeting with seven experts. Items were subsequently presented in a two-round on-line modified Delphi study to generate consensus among experts on which items are agreed as potential predictors of outcome from ESI (consensus defined as 70% agreement with ranking of remaining items).Background

Current clinical treatment for spinal instability requires invasive spinal fusion with cages and screw instrumentation. We previously reported a novel injectable hydrogel (Bgel), which supports the delivery and differentiation of mesenchymal stem cells (MSCs) to bone forming cells and supports bone formation Bovine and Human Nucleus pulpous tissue explants were injected with Bgel with and without MSCs. Tissue samples were cultured under hypoxia (5%) in standard culture media for 4 weeks. Cell viability, histological assessment of matrix deposition, calcium formation, and cell phenotype analysis using immunohistochemistry for NP matrix and bone markers.Background
Methodology
Specifically designed control interventions can account for expectation effects in clinical trials. For the interpretation of efficacy trials of physical, psychological, and self-management interventions for people living with pain, the design, conduct, and reporting of control interventions is crucial. To establish a quality standard in the field, core recommendations are presented alongside additional considerations and a reporting checklist for control interventions.Background
Objectives
The purpose of this study was to discover if student led clinics (SLC) are feasible delivery mechanisms for Low back pain (LBP) self-management support and to develop a service model. LBP is the most commonly reported musculoskeletal disorder worldwide. The increasing service and workforce demands of LBP are challenging for providers and policy makers. self-management is appropriate for many people living with LBP yet guidance for self-management is lacking. One potential delivery mechanism is through SLC. These are ‘clinics’ run by students, supervised by clinicians.Purpose
Background
Degenerative cervical myelopathy resulting in cord compromise is a progressive condition that results in significant quality of life limitations. Surgical treatment options available are anterior and/or posterior decompression of the affected levels. Patients are counselled pre-operatively that the aim of surgical intervention is to help prevent deterioration of neurology. Anecdotal evidence suggested improvements in both EMS and PROMs in this cohort of patients. A 2-year prospective study tested this hypothesis. 67 patients undergoing anterior cervical surgery were followed up to two years. Myelopathic features, radiological cord compression, myelomalacia change and levels of surgery were recorded. Pre/post intervention myelopathy scores/grades, and PROM's were recorded. Paired t-test was performed when comparing pre/post intervention scores and Annova test when comparing results across levels. Our prospective study identified statistically significant improvements in European myelopathy scores and grade and patient reported clinical outcomes in the said population.Purpose of Study and Background
Methodology and Results
Degenerative cervical myelopathy (DCM) is associated with progressive neurological deterioration. Surgical decompression can halt but not reverse this progression. The Modified Japanese Orthopaedic Assessment (MJOA) tool is recommended by international guidelines to grade disease severity into mild, moderate and severe, where moderate and severe are both recommended to undergo surgical intervention. During Covid-19 Nottingham University Hospitals (NUH) NHS Trust, identified DCM patients as high risk for sustaining permanent neurological damage due to surgical delay. The Advanced Spinal Practitioner (ASP) team implemented a surveillance project to evaluate those at risk. A spreadsheet was compiled of all DCM patients known to the service. Patients were telephoned (Oct-Nov 2021) by an ASP. MJOA score was recorded and those describing progressive deterioration were reviewed by the ASP team on a spinal same day emergency assessment unit. Incident forms were completed for clinical deterioration and recorded as severe harm. Acute, progressive neurological deterioration was fast tracked for emergency surgical decompression.Introduction
Methods
Cognitive Functional Therapy (CFT) is a psychologically informed, physiotherapist-led intervention that targets the biopsychosocial complexity of persistent low back pain (LBP). CFT has demonstrated positive outcomes in two randomised controlled trials (RCT) but has not previously been evaluated in the United Kingdom National Health Service (NHS). This study aimed to determine the feasibility of completing a definitive RCT, that will evaluate the clinical and cost-effectiveness of CFT in comparison to usual physiotherapy care (UPC) for people with persistent LBP in the NHS. A two-arm parallel feasibility RCT compared CFT with UPC in participants with persistent LBP. Data concerning study processes, resources, management and patient reported outcome measures (disability, pain intensity, quality of life and psychosocial function) were collected at baseline, three and six-month follow-up, analysed and evaluated in order to establish feasibility. Sixty participants (n=30 CFT and n=30 UPC) were recruited with 71.6% (n=43) retained at six-month follow-up. CFT was delivered to fidelity, relevant and clinically important outcome data were rigorously collected and CFT was tolerated by participants with no safety concerns. The Roland-Morris disability questionnaire was the most suitable primary outcome measure and sample size calculations were completed for a definitive RCT. Intention to treat analysis indicated a signal of effect in favour of CFT with moderate and large between group effect sizes observed across outcome measures at six-month follow-up.Purposes of the study and background

Scoliosis is described as a lateral spinal curvature exceeding ten degrees on radiograph with vertebral rotation. Approximately 80% of scoliosis presentations are adolescent idiopathic scoliosis (AIS). Current management for AIS in the UK occurs in Surgeon or Paediatrician-led clinics and can be conservative or surgical. The musculoskeletal assessment and triage of AIS appears well-suited to an advanced physiotherapist practitioner (APP) skill set. The aim of this service evaluation was to scope, develop, implement and evaluate a four-month pilot of an APP-led AIS triage pathway. Spinal Consultant deformity and scoliosis clinics were scoped and observed. Clinic inclusion criteria and a patient assessment form was developed. An APP AIS clinic was set up beside a consultant led clinic. All patients assessed were discussed with a spinal surgeon. Consultant and APP agreement (% of total), waiting times, surgical conversion, and patient satisfaction were reviewed. A clinical competency package was developed for training and development of APPs. A total of 49 patients were seen (20 sessions). Waiting list reduced from 10 weeks to 6 weeks. 45%(n=22) of new patients seen were diagnosed with AIS, 27% (n=6) were directly listed for surgery. Consultant/ APP percentage agreement was high for Cobb angle measurement (82%), management plans (90%), and further diagnostic requests (94%). There were no adverse events and high patient satisfaction levels (n=20), (100% Very satisfied or satisfied) were reported.Background
Method and Results
Serious traumatic injury is a leading cause of death and disability globally, with the majority of survivors developing chronic pain. The aims of this study were to describe early predictors of poor long-term outcome for post-trauma pain. We conducted a prospective observational study, recruiting patients admitted to a Major Trauma Centre hospital in England within 14 days of their injuries, and followed them for 12 months. We defined a poor outcome as Chronic Pain Grade ≥ II and measured this at both 6-months and 12-months. A broad range of candidate predictors were used, including surrogates for pain mechanisms, quantitative sensory testing, and psychosocial factors. Univariate models were used to identify the strongest predictors of poor outcome, which were entered into multivariate models.Background
Methods
We have previously reported an injectable hydrogel (NPgel), which could deliver patients own stem cells, via small bore needles, decreasing damage to the annulus fibrosus. NPgel drives differentiation to NP cells and can inhibit the degenerate niche. However, clinical success of NPgel is dependent on the capacity to inject NPgel into naturally degenerate human discs, restore mechanical function to the IVD, prevent extrusion during loading and induce regeneration. This study assessed injectability of NPgel into human IVD, influence on mechanical properties, regeneration ability in an Cadaveric human discs were used to calculate disc height and to determine Youngs Modulus during simulated walking pre and post injection of NPgel, extrusion testing performed. Whole human IVDs were injected with NPgel +/− human BMPCs and maintained in culture under physiological loading regime for 4 weeks. Pre and post culture MRI imaging and in line biomechanical characteristics determined. Histology and immunochemistry performed for anabolic and catabolic factors.Background
Methodology
Cauda equina syndrome (CES) is a spinal condition requiring emergency spinal surgery once diagnosed. The patient-reported symptoms are often subtle and none have been shown to be sensitive or specific in confirming CES. Magnetic resonance image (MRI) is the diagnostic gold standard, and guidelines recommend MRI access within 24-hours of symptom presentation. Limited sequence MRI scans (sagittal T2 sequences of the whole spine) have been shown to successfully identify patients with scan-positive CES despite reducing the duration of an MRI. The aim of this audit was to examine utilisation of same-day MRI requests by spinal practitioners from a newly operational same-day emergency care spinal unit over the two-year period. Data was routinely collected over the two-year period and retrospectively reviewed. Data extraction occurred for cases of suspected CES with a same-day scan. Data extraction included type of MRI scan (lumbar/ whole spine/ CES protocol); outcome (admission/ discharge); final diagnosis. After clinical examination, only 258 (24% of 1085) suspected CES cases were identified and scanned within 24 hours, 58% (n=149) of which were with CES limited sequence scans. Only 12% (n=30) demonstrated scan- positive CES resulting in surgery within 24-hours. MRI same-day requests increased between 2020 (n=81, 21%) and 2021 (n=177, 26%), although utilisation of limited sequence scans improved (n=39, 48% in 2020; n=109, 62% in 2021).Background
