Gram-negative infections are associated with comorbid patients, but outcomes are less well understood. This study reviewed diagnosis, management, and treatment for a cohort treated in a tertiary spinal centre. A retrospective review was performed of all gram-negative spinal infections (n = 32; median age 71 years; interquartile range 60 to 78), excluding surgical site infections, at a single centre between 2015 to 2020 with two- to six-year follow-up. Information regarding organism identification, antibiotic regime, and treatment outcomes (including clinical, radiological, and biochemical) were collected from clinical notes.Aims
Methods
In this investigation, we administered oxidative stress to nucleus pulposus cells (NPCs), recognized DNA-damage-inducible transcript 4 (DDIT4) as a component in intervertebral disc degeneration (IVDD), and devised a hydrogel capable of conveying small interfering RNA (siRNA) to IVDD. An in vitro model for oxidative stress-induced injury in NPCs was developed to elucidate the mechanisms underlying the upregulation of DDIT4 expression, activation of the reactive oxygen species (ROS)-thioredoxin-interacting protein (TXNIP)-NLRP3 signalling pathway, and nucleus pulposus pyroptosis. Furthermore, the mechanism of action of small interfering DDIT4 (siDDIT4) on NPCs in vitro was validated. A triplex hydrogel named siDDIT4@G5-P-HA was created by adsorbing siDDIT4 onto fifth-generation polyamidoamine (PAMAM) dendrimer using van der Waals interactions, and then coating it with hyaluronic acid (HA). In addition, we established a rat puncture IVDD model to decipher the hydrogel’s mechanism in IVDD.Aims

This systematic review aims to identify 3D predictors derived from biplanar reconstruction, and to describe current methods for improving curve prediction in patients with mild adolescent idiopathic scoliosis. A comprehensive search was conducted by three independent investigators on MEDLINE, PubMed, Web of Science, and Cochrane Library. Search terms included “adolescent idiopathic scoliosis”,“3D”, and “progression”. The inclusion and exclusion criteria were carefully defined to include clinical studies. Risk of bias was assessed with the Quality in Prognostic Studies tool (QUIPS) and Appraisal tool for Cross-Sectional Studies (AXIS), and level of evidence for each predictor was rated with the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. In all, 915 publications were identified, with 377 articles subjected to full-text screening; overall, 31 articles were included.Aims
Methods
To systematically evaluate whether bracing can effectively achieve curve regression in patients with adolescent idiopathic scoliosis (AIS), and to identify any predictors of curve regression after bracing. Two independent reviewers performed a comprehensive literature search in PubMed, Ovid, Web of Science, Scopus, and Cochrane Library to obtain all published information about the effectiveness of bracing in achieving curve regression in AIS patients. Search terms included “brace treatment” or “bracing,” “idiopathic scoliosis,” and “curve regression” or “curve reduction.” Inclusion criteria were studies recruiting patients with AIS undergoing brace treatment and one of the study outcomes must be curve regression or reduction, defined as > 5° reduction in coronal Cobb angle of a major curve upon bracing completion. Exclusion criteria were studies including non-AIS patients, studies not reporting p-value or confidence interval, animal studies, case reports, case series, and systematic reviews. The GRADE approach to assessing quality of evidence was used to evaluate each publication.Aims
Methods
Scoliosis is a lateral curvature of the spine with associated rotation, often causing distress due to appearance. For some curves, there is good evidence to support the use of a spinal brace, worn for 20 to 24 hours a day to minimize the curve, making it as straight as possible during growth, preventing progression. Compliance can be poor due to appearance and comfort. A night-time brace, worn for eight to 12 hours, can achieve higher levels of curve correction while patients are supine, and could be preferable for patients, but evidence of efficacy is limited. This is the protocol for a randomized controlled trial of ‘full-time bracing’ versus ‘night-time bracing’ in adolescent idiopathic scoliosis (AIS). UK paediatric spine clinics will recruit 780 participants aged ten to 15 years-old with AIS, Risser stage 0, 1, or 2, and curve size (Cobb angle) 20° to 40° with apex at or below T7. Patients are randomly allocated 1:1, to either full-time or night-time bracing. A qualitative sub-study will explore communication and experiences of families in terms of bracing and research. Patient and Public Involvement & Engagement informed study design and will assist with aspects of trial delivery and dissemination.Aims

Implant-related postoperative spondylodiscitis (IPOS) is a severe complication in spine surgery and is associated with high morbidity and mortality. With growing knowledge in the field of periprosthetic joint infection (PJI), equivalent investigations towards the management of implant-related infections of the spine are indispensable. To our knowledge, this study provides the largest description of cases of IPOS to date. Patients treated for IPOS from January 2006 to December 2020 were included. Patient demographics, parameters upon admission and discharge, radiological imaging, and microbiological results were retrieved from medical records. CT and MRI were analyzed for epidural, paravertebral, and intervertebral abscess formation, vertebral destruction, and endplate involvement. Pathogens were identified by CT-guided or intraoperative biopsy, intraoperative tissue sampling, or implant sonication.Aims
Methods
To determine whether side-bending films in scoliosis are assessed for adequacy in clinical practice; and to introduce a novel method for doing so. Six surgeons and eight radiographers were invited to participate in four online surveys. The generic survey comprised erect and left and right bending radiographs of eight individuals with scoliosis, with an average age of 14.6 years. Respondents were asked to indicate whether each bending film was optimal (adequate) or suboptimal. In the first survey, they were also asked if they currently assessed the adequacy of bending films. A similar second survey was sent out two weeks later, using the same eight cases but in a different order. In the third survey, a guide for assessing bending film adequacy was attached along with the radiographs to introduce the novel T1-45B method, in which the upper endplate of T1 must tilt ≥ 45° from baseline for the study to be considered optimal. A fourth and final survey was subsequently conducted for confirmation.Aims
Methods
This study aimed, through bioinformatics analysis and in vitro experiment validation, to identify the key extracellular proteins of intervertebral disc degeneration (IDD). The gene expression profile of GSE23130 was downloaded from the Gene Expression Omnibus (GEO) database. Extracellular protein-differentially expressed genes (EP-DEGs) were screened by protein annotation databases, and we used Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) to analyze the functions and pathways of EP-DEGs. STRING and Cytoscape were used to construct protein-protein interaction (PPI) networks and identify hub EP-DEGs. NetworkAnalyst was used to analyze transcription factors (TFs) and microRNAs (miRNAs) that regulate hub EP-DEGs. A search of the Drug Signatures Database (DSigDB) for hub EP-DEGs revealed multiple drug molecules and drug-target interactions.Aims

Symptomatic spinal stenosis is a very common problem, and decompression surgery has been shown to be superior to nonoperative treatment in selected patient groups. However, performing an instrumented fusion in addition to decompression may avoid revision and improve outcomes. The aim of the SpInOuT feasibility study was to establish whether a definitive randomized controlled trial (RCT) that accounted for the spectrum of pathology contributing to spinal stenosis, including pelvic incidence-lumbar lordosis (PI-LL) mismatch and mobile spondylolisthesis, could be conducted. As part of the SpInOuT-F study, a pilot randomized trial was carried out across five NHS hospitals. Patients were randomized to either spinal decompression alone or spinal decompression plus instrumented fusion. Patient-reported outcome measures were collected at baseline and three months. The intended sample size was 60 patients.Aims

Lumbar spinal stenosis (LSS) is a common skeletal system disease that has been partly attributed to genetic variation. However, the correlation between genetic variation and pathological changes in LSS is insufficient, and it is difficult to provide a reference for the early diagnosis and treatment of the disease. We conducted a transcriptome-wide association study (TWAS) of spinal canal stenosis by integrating genome-wide association study summary statistics (including 661 cases and 178,065 controls) derived from Biobank Japan, and pre-computed gene expression weights of skeletal muscle and whole blood implemented in FUSION software. To verify the TWAS results, the candidate genes were furthered compared with messenger RNA (mRNA) expression profiles of LSS to screen for common genes. Finally, Metascape software was used to perform enrichment analysis of the candidate genes and common genes.Aims
Methods
To determine the major risk factors for unplanned reoperations (UROs) following corrective surgery for adult spinal deformity (ASD) and their interactions, using machine learning-based prediction algorithms and game theory. Patients who underwent surgery for ASD, with a minimum of two-year follow-up, were retrospectively reviewed. In total, 210 patients were included and randomly allocated into training (70% of the sample size) and test (the remaining 30%) sets to develop the machine learning algorithm. Risk factors were included in the analysis, along with clinical characteristics and parameters acquired through diagnostic radiology.Aims

The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months.Aims

Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS.Aims

CRP is an acute-phase protein that is used as a biomarker to follow severity and progression in infectious and inflammatory diseases. Its pathophysiological mechanisms of action are still poorly defined. CRP in its pentameric form exhibits weak anti-inflammatory activity. The monomeric isoform (mCRP) exerts potent proinflammatory properties in chondrocytes, endothelial cells, and leucocytes. No data exist regarding mCRP effects in human intervertebral disc (IVD) cells. This work aimed to verify the pathophysiological relevance of mCRP in the aetiology and/or progression of IVD degeneration. We investigated the effects of mCRP and the signalling pathways that are involved in cultured human primary annulus fibrosus (AF) cells and in the human nucleus pulposus (NP) immortalized cell line HNPSV-1. We determined messenger RNA (mRNA) and protein levels of relevant factors involved in inflammatory responses, by quantitative real-time polymerase chain reaction (RT-qPCR) and western blot. We also studied the presence of mCRP in human AF and NP tissues by immunohistochemistry.Aims

This study was performed to explore the effect of melatonin on pyroptosis in nucleus pulposus cells (NPCs) and the underlying mechanism of that effect. This experiment included three patients diagnosed with lumbar disc herniation who failed conservative treatment. Nucleus pulposus tissue was isolated from these patients when they underwent surgical intervention, and primary NPCs were isolated and cultured. Western blotting, reverse transcription polymerase chain reaction, fluorescence staining, and other methods were used to detect changes in related signalling pathways and the ability of cells to resist pyroptosis.Aims

To investigate the correlations among cytokines and regulatory T cells (T-regs) in ankylosing spondylitis (AS) patients, and their changes after anti-tumour necrosis factor-α (TNF-α) treatment. We included 72 AS patients with detailed medical records, disease activity score (Bath Ankylosing Spondylitis Disease Activity Index), functional index (Bath Ankylosing Spondylitis Functional Index), and laboratory data (interleukin (IL)-2, IL-4, IL-10, TNF-α, interferon (IFN)-γ, transforming growth factor (TGF)-β, ESR, and CRP). Their peripheral blood mononuclear cells (PBMCs) were marked with anti-CD4, anti-CD25, and anti-FoxP3 antibodies, and triple positive T cells were gated by flow cytometry as T-regs. Their correlations were calculated and the changes after anti-TNF-α therapy were compared.Aims

Use of ultrasonic bone scalpel (UBS) is becoming popular in spinal surgery. This study presents the safety profile of UBS for posterior release in surgical correction of adolescent idiopathic scoliosis (AIS). From 2016 to 2018, UBS (Misonix) was used by the senior author in a variety of spinal operations. Data for intraoperative complications when this devise was used for posterior correction of AIS were collected. Revision cases were excluded. UBS was used for posterior release of AIS in 65 patients (58 female, seven male) with an average age of 15.6 years (range 11–23). Average length of posterior instrumentation was 12 levels (range 6–14). Instrumentation was exclusively from T2 to L4. To achieve adequate release for correction, UBS was used to perform a total of 644 modified in-situ chevron osteotomies (average ten, range six to 12) and 31 rib osteotomies. Overall, three complications (4.6 %) were directly related to the use of UBS: one haemopneumothorax, which was successfully treated with a chest drain; and two loss of motor-evoked potentials during monitoring, which led to the postponement of the final correction. These two patients did not have any neurological problems and their surgery was completed successfully within 1 week of the initial surgery. One late deep infection was reported. This was not thought to be directly related to the use of UBS. Use of UBS in the posterior surgical treatment of AIS appears to be relatively safe with a low level of acceptable complications. However, appropriate training is required for the use of UBS.
We present a large single surgeon case series evaluation of a new growth guidance technique for the treatment of progressive early onset scoliosis (EOS). A traditional Luque trolley construct uses wires to hold growth guidance rods together. We describe a new technique that uses domino end to side connectors in place of the wires with the aim of providing a stronger construct to better limit curve progression, while allowing longitudinal growth. We did a thorough retrospective review of patient records and radiological imaging. Sequential measurements of Cobb angle and length of rods were recorded, as well as any further surgical procedures and associated complications. This enabled us to quantify the ability of a technique to limit curve progression and simultaneously allow growth of the construct. In total, 28 patients with EOS (20 idiopathic, four syndromic, and four neuromuscular) have been treated with this technique, 25 of whom have a minimum follow-up of 2 years and 13 have a minimum follow-up of 5 years. The average correction of the preoperative Cobb angle was 48.9%. At the 2-year follow up, the average loss of this initial correction was 15 degrees, rising to only 20 degrees at a minimum of 5 years (including four patients with a follow-up of 8 years or more). The growth of the constructs was limited. The average growth at 2 years was 3.7 mm, rising to 19 mm at the 5-year follow-up. Patients who underwent surgery with this technique before the age of 8 years seemed to do better. This group had a revision rate of only 18% at an average time of 7 years after the index procedure, and the average growth was 22 mm. However, the group that had index surgery after the age of 8 years had a 64% revision rate at an average of 3.2 years after surgery and an average growth of only 11.6 mm. Overall, in the cases series, there were four hardware failures (14%) and one deep infection (3.5%), and only ten patients (36%) had one extra surgery after the index procedure. Only two of the 13 patients who are at a follow-up of 5 years or more have had revision. This modified Luque trolley technique has a good capacity for initial curve correction and for limiting further curve progression, with limited longitudinal growth before 2 years and improved growth thereafter. This technique might not be so useful after the age of 8 years because of poor growth and a higher early revision rate. We have also demonstrated a low cost technique with a low hardware failure rate that saves many future surgeries for the patient compared with other techniques used in the treatment of EOS.
To determine whether spinal facet osteoblasts at the curve apex display a different phenotype to osteoblasts from outside the curve in patients with adolescent idiopathic scoliosis (AIS). Intrinsic differences in the phenotype of spinal facet bone tissue and in spinal osteoblasts have been implicated in the pathogenesis of AIS. However, no study has compared the phenotype of facet osteoblasts at the curve apex with the facet osteoblasts from outside the curve in patients with AIS. Facet bone tissue was collected from three sites, the concave and convex side at the curve apex and from outside the curve from three female patients with AIS (aged 13–16 years). Micro-CT analysis was used to determine the density and trabecular structure. Osteoblasts were then cultured from the sampled bone. Osteoblast phenotype was investigated by assessing cellular proliferation (MTS assay), cellular metabolism (alkaline phosphatase and Seahorse Analyser), bone nodule mineralisation (Alizarin red assay), and the mRNA expression of Wnt signalling genes (quantitative RT-PCR). Convex bone showed greater bone mineral density and trabecular thickness than did concave bone. The convex side of the curve apex exhibited a significantly higher proliferative and metabolic phenotype and a greater capacity to form mineralised bone nodules than did concave osteoblasts. mRNA expression of SKP2 was significantly greater in both concave and convex osteoblasts than in non-curve osteoblasts. The expression of SFRP1 was significantly downregulated in convex osteoblasts compared with either concave or non-curve. Intrinsic differences that affect osteoblast function are exhibited by spinal facet osteoblasts at the curve apex in patients with AIS.
Spinal deformations are posture dependent. Official data from the Netherlands show that youth are encountering increasing problems with the musculoskeletal system (>40% back pain, and sport injury proneness). Prolonged sloth and slumped sitting postures are causative factors. Dutch youth are “champion sitting” in Europe. The effects of sitting on the development of posture and function of locomotion (stiffness) during growth have only been reported clearly in classic textbooks (in German) of practical anatomy and orthopaedics. Research with relevant clinical examinations is being done to understand epidemiological data on the increasing posture-dependent problems. A cohort of adolescents (15–18 years) in secondary school was assessed for sagittal postural deviations while bending. 248 children completed a questionnaire, and tests were done on neuromuscular tightness. The femorotibial angle was used to measure hamstring tightness. Measurement of the dorsiflexion of the foot was used to assess the tightness of calf muscles and Achilles tendons. All adolescents were photographed laterally while performing the finger–floor test (used to test flexibility), assessed as a knockout test: “Can you reach the floor or not?” The spinal profiles while bending were classified as abnormal arcuate or angular kyphosis. Hamstring tightness was present in 62.1% of the cohort in both legs, and in 18.2% unilaterally. Achilles tendon tightness was present bilaterally in 59.3%, and unilaterally in 19.4%. Activities with presence of stiffness (finger–floor distance), in descending order, were football, running, no sports, field hockey, tennis, dance, and gymnastics. 93.5% of the soccer players had tight hamstrings in both legs compared with none of those performing gymnastics. The correlation of the finger–floor test with tight hamstrings was 73.2%. For sagittal bending deformities, the correlation between form and function deficits cannot be made yet. 80 of 248 spines were rated by the examiners as having deformed flexion. Since Andry (1741) and at the zenith of continental orthopaedics and anatomy around 1900, the prolonged flexed positions of a young spine were indicated as being the main cause of deformity by overload and shear loads on immature discs and cartilage, preventing normal development of the discs. Nachemson proved that the intradiscal pressure in sitting adults was extremely high, so it follows that children must also be at risk. Evidence suggests that youth, generally because of their sedentary and “screenful lifestyle”, will encounter serious problems in growth, manifesting as incongruent neuro-osseous growth (Roth), serious neuromuscular tightness (being prone to injury), and spinal deformations, leading to pain.
Degenerative cervical spondylosis (DCS) is a common musculoskeletal disease that encompasses a wide range of progressive degenerative changes and affects all components of the cervical spine. DCS imposes very large social and economic burdens. However, its genetic basis remains elusive. Predicted whole-blood and skeletal muscle gene expression and genome-wide association study (GWAS) data from a DCS database were integrated, and functional summary-based imputation (FUSION) software was used on the integrated data. A transcriptome-wide association study (TWAS) was conducted using FUSION software to assess the association between predicted gene expression and DCS risk. The TWAS-identified genes were verified via comparison with differentially expressed genes (DEGs) in DCS RNA expression profiles in the Gene Expression Omnibus (GEO) (Accession Number: GSE153761). The Functional Mapping and Annotation (FUMA) tool for genome-wide association studies and Meta tools were used for gene functional enrichment and annotation analysis.Aims

The number of patients undergoing surgery for degenerative cervical radiculopathy has increased. In many countries, public hospitals have limited capacity. This has resulted in long waiting times for elective treatment and a need for supplementary private healthcare. It is uncertain whether the management of patients and the outcome of treatment are equivalent in public and private hospitals. The aim of this study was to compare the management and patient-reported outcomes among patients who underwent surgery for degenerative cervical radiculopathy in public and private hospitals in Norway, and to assess whether the effectiveness of the treatment was equivalent. This was a comparative study using prospectively collected data from the Norwegian Registry for Spine Surgery. A total of 4,750 consecutive patients who underwent surgery for degenerative cervical radiculopathy and were followed for 12 months were included. Case-mix adjustment between those managed in public and private hospitals was performed using propensity score matching. The primary outcome measure was the change in the Neck Disability Index (NDI) between baseline and 12 months postoperatively. A mean difference in improvement of the NDI score between public and private hospitals of ≤ 15 points was considered equivalent. Secondary outcome measures were a numerical rating scale for neck and arm pain and the EuroQol five-dimension three-level health questionnaire. The duration of surgery, length of hospital stay, and complications were also recorded.Aims

The aims of this study were first, to determine if adding fusion to a decompression of the lumbar spine for spinal stenosis decreases the rate of radiological restenosis and/or proximal adjacent level stenosis two years after surgery, and second, to evaluate the change in vertebral slip two years after surgery with and without fusion. The Swedish Spinal Stenosis Study (SSSS) was conducted between 2006 and 2012 at five public and two private hospitals. Six centres participated in this two-year MRI follow-up. We randomized 222 patients with central lumbar spinal stenosis at one or two adjacent levels into two groups, decompression alone and decompression with fusion. The presence or absence of a preoperative spondylolisthesis was noted. A new stenosis on two-year MRI was used as the primary outcome, defined as a dural sac cross-sectional area ≤ 75 mm2 at the operated level (restenosis) and/or at the level above (proximal adjacent level stenosis).Aims

Advice and education are considered vital components of back pain care within national guidelines. However, a recent systematic review only found low grade evidence for a small average effect. They also reported wide heterogeneity in intervention design and delivery. This review aimed to understand why intervention design varied and what limited effectiveness by examining the underlying theoretical foundations of the studies from that review. Population, context, selection criteria, intervention(s), control, outcome measures, how the intervention was hypothesised to produce outcomes and author recommendations based on results of the study were extracted from text records. The extent to which the advice included matched a published international consensus statement on evidence-based advice for back pain was recorded. Whether interventions or settings were complex was determined using the Medical Research Council complex intervention development and evaluation guidance and the extent to which they met complexity reporting criteria was recorded.Background

Low back pain with no identified underlying cause is categorised as primary musculoskeletal pain by the International Association for the Study of Pain. In April 2021, the National Institute for Care and Excellence (NICE) published updated guidance for the management of primary chronic pain conditions in England. As part of the De-STRESS pain study, we explored the perspectives of GPs on the updated guideline and impact upon clinical practice. Semi-structured interviews were conducted with 21 GPs in England. Data were analysed using thematic analysis and constant comparison techniques. GPs agreed with the recommendations restricting pharmacological options for pain management and reflected that they now had an expert reference to back-up their decision-making and could use the guidance in potentially difficult conversations with patients. Frustration was expressed by GPs about the lack of alternative options to medication, as the non-pharmacological recommendations were difficult to implement, had lengthy waiting lists, or were unavailable in their locality.Background and study purpose

Advanced practice physiotherapists (APPs) manage the national low back and radicular pain pathway across the UK. A novel spinal APP-led same-day emergency care (SDEC) pathway in Nottingham, manages patients referred from community services and the emergency department (ED). Patients may attend ED in the belief their pain is due to sinister or ‘red flag’ pathology. Little data exists on prevalence of spinal ‘red flag’ pathologies within a secondary care setting. This paper aims to review the number of ‘red flag’ pathology identified by APP's on a same-day emergency care pathway. Retrospective data from 1 year of routinely collected information was extracted and analysed by two APPs. Counts were reported as a percentage of total patients seen on the SDEC unit over a one-year period and compared to nationally reported figures. A total of 2042 patients were assessed on the unit in 2021, of which, 293 (14%) had serious pathology identified. Patients were classified into type of serious pathology: myelopathy (126, 6.1%), fractures (72, 3.5%), cauda equine compression (40, 1.9%), infection (37, 1.8%), cancers (28, 1.3%), neurological conditions (14, 0.6%) and other (16, 0.8%) serious pathology.Introduction

BANDAIDE aka Back and Neck Discomfort relief with Altered behaviour, Intelligent Postures, Dynamic movement and Exercises (ISBN - 0995676933) is a concise self-help booklet containing strengthening exercises and illustrated information to enable patients self-manage their back and neck pain. The aim of this preliminary audit was to determine patient opinion on BANDAIDE. Institutional audit approval was obtained – No. 8429. BANDAIDE was distributed to 40 patients, who were asked to evaluate the booklet using the Usefulness Scale for Patient Information Material (USE). USE consists of nine positive statements which are subdivided into three sub-domains; cognition, emotional and behavioural. The cognition sub-domain assesses the knowledge obtained from the material, the emotional sub-domain evaluates the effects of the material on an individual's ability to cope with the illness and the behavioural sub-domain assesses ability to self-manage. Responders were required to rate the extent to which they agreed with each of the nine statements on a scale of 0 to 10, where 0 denotes ‘completely disagree’ and 10 denotes ‘completely agree’. Each subsection is on a scale of 0–30, with a higher score suggesting better usefulness. 23 participants provided their opinions of BANDAIDE through the USE. For the three sub-domains, the mean ratings for cognition, emotional and behavioural were 27.2, 24.7, and 26.4 respectively.Background
Methods and Results
Chronic low back pain (CLBP) is the leading cause of disability worldwide. Immersive virtual reality (IVR) can be delivered using head mounted display (HMD) to interact with 3D virtual environment (VE). IVR has shown promising results in management of chronic pain conditions, using different mechanisms (e.g., exposure to movement and distraction). However, it has not been widely tested for CLBP. Future development of IVR intervention needs inputs from gatekeepers to determine key considerations, facilitators and barriers. This qualitative study aimed to explore views and opinions of physiotherapists about IVR intervention for adults with CLBP. Four focus groups were conducted online, with 16 physiotherapists. A demonstration of existing IVR mechanisms was presented. The data were transcribed and analysed through descriptive thematic analysis.Background

Cauda Equina Syndrome (CES) is a surgical emergency. With Physiotherapists increasingly taking on first-contact and spinal triage roles, screening for CES must be as thorough and effective as possible. This study explores whether Physiotherapists are asking the correct questions, in the correct way and investigates their experiences when screening for this serious condition. Thirty physiotherapists working in a community musculoskeletal service were purposively invited to participate in semi-structured interviews. Data was transcribed and thematically analysed.Purpose of study
Background
Low back pain (LBP) is a major problem across the globe and is the leading cause worldwide of years lost to disability. Self-management is considered an important component the treatment of people with non-specific LBP. However, it seems that the self-management support for people with non-specific LBP provided by physiotherapists can be improved. Moreover, the way exercise therapists (ET) address self-management in practice is unknown. To investigate the ideas, opinions and methods used by physiotherapists and ET with regard to self-management and providing self-management support to patients with non-specific LBP.Background
Purpose
Psychological factors are considered to play a role in development and maintenance of chronic low back pain (CLBP). Stress or anxiety can change pain sensitivity; however, this has predominantly been studied in healthy individuals with limited work in individuals with musculoskeletal pain. The objective of this study was to quantify the effect of acute exposure to a psychosocial stressor on mechanical pain sensitivity in individuals with and without CLBP. Six individuals with CLBP and 10 individuals without CLBP performed a 10-minute computer task under conditions of low and high psychosocial stress. Psychosocial stress was manipulated using mental maths and memory tasks combined with social evaluative threat. The effect of the stressor was evaluated using blood pressure, heart rate and the state anxiety component of the Spielberger State-Trait Anxiety Index. Mechanical pressure pain threshold (PPT) was recorded on the tibialis anterior muscle using a handheld digital pressure algometer. The stress manipulation increased self-reported anxiety (p<0.001), but not blood pressure or heart rate (p>0.06). Change in PPT from low to high stress was greater in the CLBP group (median ΔPPT = −0.5 kg/cm2) than in the control group (−0.15 kg/cm2; p=0.005).Purpose of study and background
Summary of methods and results
An improved understanding of intervertebral disc (IVD) structure and function is required for treatment development. Loading induces micro-fractures at the interface between the nucleus pulposus (NP) and the annulus fibrosus (AF), which is hypothesized to induce a cascade of cellular changes leading to degeneration. However, there is limited understanding of the structural relationship between the NP and AF at this interface and particularly response to load. Here, X-ray scattering is utilised to provide hierarchical morphometric information of collagen structure across the IVD, especially the interface region under load. IVDs were imaged using the I22 SAXS/WAXS beamline at Diamond Light Source. Peaks associated with the D-banded structure of collagen fibrils were fitted to quantify their azimuthal distribution, as well the magnitude and direction of internal strains under static and applied strain (0–20%).Background
Methodology
NHS improvement advocates same day emergency care (SDEC) for patients requiring additional specialism than can be provided in an Emergency Department. A novel physiotherapist-led spinal SDEC unit was established in January 2020, integrated within the on-call spinal service. The aim of this paper was to evaluate patient and peer satisfaction with the spinal SDEC. Patient satisfaction questionnaires and/or friends and family tests were collected from patients over a six-month period. Questionnaires evaluated satisfaction with recommendations given, service given, staff friendliness. Anonymous, completed questionnaires were uploaded onto a spreadsheet. Peer satisfaction was assessed using a google sheets document emailed to interface, primary care and community services. The questionnaire captured the respondents’ role, how many patients they had referred to the SDEC, reasons for referral, ease of referral, and compared this new pathway with the previous pathway. All patient's satisfaction responses recommended the service to family and friends (n=110 extremely likely, 8 likely) (6% total seen). All respondents were satisfied with the service they received (n=80 very satisfied, n=12 satisfied) and recommendations made (n=86 very satisfied, n=6 satisfied). Of peer satisfaction, 26 respondents (n=12 (46%) physiotherapists, n=6 (23%) first contact practitioners, n=6 (23%) advanced practice physiotherapists, n=1 (4%) GP, n=1 (4%) nurse) reported the SDEC delivered a better pathway and outcomes (n=25, 96%), and 20 (77%) respondents reported favourable comments of the service and its impact on patients and referrers.Background
Methods
Patients with low back pain are increasing globally. Physical dysfunction and psychosocial factors such as stress, anxiety, and fear of movement, often referred to as yellow flags, play a role in the persistence of low back pain. What is not known is the extent to which yellow flags are screened for and treatment adjusted accordingly by Physiotherapists in India. The aim was to determine the current knowledge and awareness of physiotherapists in India regarding psychosocial factors for managing patients with low back pain. Semi-structured interviews gathered data from of six physiotherapists, The interviews were conducted online. The data was transcribed and analysed using thematic analysis.Purpose and Background
Methods
Patients’ engagement with self-management strategies (SMS) is key when managing low back pain (LBP) and relies on appropriate information being delivered by the treating Clinician. However, patients have differing coping mechanisms which may affect success with SMS. This study aimed to determine Patient and Physiotherapist's perceptions of coping responses and SMS in patients with LBP. Patient completed a Pain Coping strategies questionnaire, before and after LBP treatment. Semi-structured interviews gathered data from of 10 patients (6 males; and 6 physiotherapists. Questionnaire data was described descriptively, and qualitative data was transcribed/analysed thematically.Purpose and Background
Methods
Low back pain resulting from Intervertebral disc (IVD) degeneration is a serious worldwide problem, with poor treatment options available. Notochordal (NC) cells, are a promising therapeutic cell source with anti-catabolic and regenerative effect, however, their behaviour in the harsh degenerate environment is unknown. Thus, we aimed to investigate and compare their physiological behaviour in Porcine NC cells were encapsulated in 3D alginate beads to maintain their phenotype then cultured in media to mimic the healthy and degenerate disc environment, together with control NC media for 1 week. Following which viability using PI and Calcein AM, RNA extraction and RT-PCR for NC cell markers, anabolic and catabolic genes analysed. Proteomic analysis was also performed using Digiwest technology.Backgrounds and aim
Methodology
Low back pain can lead to neuroplastic changes in the central nervous system, known as nociplastic pain. As nociplastic pain may be provoked by premorbid sensory profiles, such profiles may be prognostic in the development of nociplastic pain over time. To investigate whether four sensory profiles are prognostic in the development of symptoms of nociplastic pain in people with acute low back pain.Background
Objectives
Involving research users in setting priorities for research is essential to ensure research outcomes are patient-centred and to maximise research value and impact. The Musculoskeletal (MSK) Disorders Research Advisory Group Versus Arthritis led a research priority setting exercise across MSK disorders. The Child Health and Nutrition Research Initiative (CHRNI) method of setting research priorities with a range of stakeholders were utilised. The MSKD RAG identified, through consensus, four research Domains: Mechanisms of Disease; Diagnosis and Impact; Living Well with MSK disorders and Successful Translation. Following ethical approval, the research priority exercise involved four stages and two surveys, to: 1) gather research uncertainties; 2) consolidate these; 3) score uncertainties using agreed criteria of importance and impact on a score of 1–10; and 4) analyse scoring, for prioritisation.Background
Methods
Internet delivered interventions may provide a route to rapid support for behavioural self-management for low back pain (LBP) that could be widely applied within primary care. Although evidence is emerging that more complex technologies (mobile apps linked to digital wristbands) can have some impact on LBP-related disability, there is a need to determine the effectiveness of highly accessible, web-based support for self-management for LBP. We conducted a multi-centre pragmatic randomised controlled trial, testing ‘SupportBack’, an accessible internet intervention developed specifically for primary care. We aimed to determine the effectiveness of the SupportBack interventions in reducing LBP-related physical disability in primary care patients. Participants were randomised to 1 of 3 arms: 1) Usual care + internet intervention + physiotherapy telephone support, 2) Usual care + internet intervention, 3) Usual care alone. Utilising a repeated measures design, the primary outcome for the trial was disability over 12 months using the Roland Morris Disability Questionnaire (RMDQ) at 6 weeks, 3, 6 and 12 months. Results: 826 were randomised, with follow-up rates: 6 weeks = 83%; 3 months = 72%; 6 months = 70%; 12 months = 79%. Analysis is ongoing, comparing each intervention arm versus usual care alone. The key results will be presented at the conference.Background

Spinal muscle area (SMA) is often employed to assess muscle functionality and is important for understanding the risk individuals may have of developing back pain or the risk of postural instability and falls.. However, handgrip strength (HGS) has also been utilized as a measure of general muscle capacity. This study aimed to examine the relationship between SMA and HGS to assess whether the latter could be used as an accurate indicator of the former. 150 participants (75 males and 75 females, aged 47–70 years) were selected from the UK Biobank dataset. Handgrip strength values were extracted and averaged over left and right values. Abdominal MRI images were examined and cross-sectional area of the erector spinae and multifidus determined at the L3/4 level and summed to provide a total muscle area.Purpose of study and background
Methods
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
Methods and results
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
Methods
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
Methods
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
