Background and objectives. The Alexander Technique (AT) is a self-care method usually taught in one-to-one lessons. AT lessons have been shown to be helpful in managing long-term health-related conditions (Int J Clin Pract 2012;66:98−112). This systematic review aims to draw together evidence of the effectiveness of AT lessons in managing musculoskeletal (MSK) conditions, with empirically based evidence of physiological changes following AT training, to provide a putative theoretical explanation for the observed benefits of Alexander lessons. Methods and results. Systematic searches of a range of databases were undertaken to identify prospective studies evaluating AT instruction for any musculoskeletal condition, using PICO criteria, and for studies assessing the physiological effects of AT training. Citations (N=332) were assessed and seven MSK intervention studies were included for further analysis. In two large well-designed randomised controlled trials, AT lessons led to significant long-term (1 year) reductions in pain and incapacity caused by chronic back or neck pain (usual GP-led care comparator). Three smaller RCTs in chronic back and neck pain, respectively, and a pain clinic service evaluation broadly supported these findings. A pilot study reported preliminary evidence for pain reduction in knee osteoarthritis patients. Further studies showed significant improvements in general coordination, walking gait, motor control and balance, possibly resulting from improved postural muscle tone regulation and adaptability, in people with extensive AT training. Conclusion. Available evidence supports the effectiveness of AT lessons for people with chronic back or neck pain. Studies suggest some of the observed benefit may be due to improvements in movement coordination, balance and postural tone. Conflicts of interest: None.

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.

To evaluate the current biomechanical and clinical evidence available on the use and effectiveness of lumbar interspinous devices. Literature review. A PubMed search was done using the following key words: interspinous implants, interspinous devices, interspinous spacers, dynamic stabilization, X-stop, Coflex, Wallis, DIAM. The abstracts of all the articles were reviewed. Further critical analysis was done of the relevant articles. Special emphasis was given to those articles pertaining to biomechanical and clinical results. A total of 50 articles were found, 18 of them also related to the effect of spacers on the biomechanics of the spine. 25 articles were on the X-stop device. However, level I evidence is lacking. Only two prospective randomized controlled trials have been done and these were on the X-Stop device. Analysis of current evidence suggests a potential beneficial effect of lumbar interspinous spacers in select group of patients. However, further level I evidence is required to justify their widespread use for all the proposed indications. The results of the ongoing trials are keenly awaited

Purposes of the study and background. An increasing number of clinical studies involving a range of chronic pain conditions report widespread mechanical pressure pain hypersensitivity, which is commonly interpreted as resulting from central sensitization (CS). Secondary hyperalgesia (increased pinprick sensitivity surrounding the site of injury) is considered to be a manifestation of central sensitization. However, it has not been rigorously tested whether central sensitization induced by peripheral nociceptive input, involves widespread mechanical pressure pain hypersensitivity. The aim of this study was to assess whether high frequency electrical stimulation (HFS), which induces a robust secondary hyperalgesia, also induces a widespread decrease of pain pressure thresholds (PPTs). Summary of the methods and results. We measured PPTs bilaterally on the temples (temporalis muscles), on the legs (tibialis anterior muscles) and on the ventral forearm (flexor carpi radialis muscles) before, 20 min after, and 45 min after applying HFS on the ventral forearm of sixteen healthy young volunteers. To evaluate the presence of secondary hyperalgesia, mechanical pin-prick sensitivity was assessed on the skin surrounding the site where HFS was applied and also on the contralateral arm. HFS induced a significant increase in mechanical pinprick sensitivity on the HFS-treated arm. However, HFS did not decrease PPTs either in the area of increased pinprick sensitivity nor at more distant sites. Conclusion. The present study provides no evidence for the hypothesis that central sensitization, induced after intense activation of skin nociceptors, involves a widespread decrease of PPTs. No conflicts of interest. Sources of Funding: This study was funded by the Université Catholique de Louvain

Background. Current policy and practice aimed at tackling work disability due to low back pain is largely aligned with the Psychosocial Flags Framework, which focuses on addressing individual beliefs and behaviours (yellow and blue flags). However, our understanding of the systemic and contextual factors (black flags) that are also proposed to act as obstacles within this Framework is under-represented, resulting in a disproportionate evidence base and suboptimal interventions. Methods. A ‘best-evidence’ synthesis was conducted to collate the evidence on those ‘black flags’ proposed to be the most important: compensatory systems (worker's compensation and disability benefits), healthcare provider systems and ‘significant others’ (spouse/partner/close family members). A systematic search of scientific and grey literature databases was performed, and the validity and merit of the available evidence was assessed using a system adapted from previous large-scale policy reviews conducted in this field. Results. Following a systematic exclusion process, 65 articles were selected from 1,762 records. Robust, credible and meaningful evidence was found to show that inflexible compensatory systems, a lack of ‘work-focused’ healthcare and communication amongst return-to-work stakeholders, along with inappropriate support from ‘significant others’ are obstacles to work participation for those with low back pain. Conclusions. This is the first attempt at synthesising the evidence on the ‘social’ factors proposed to be important influences on work disability due to low back pain within the Psychosocial Flags Framework. Results have relevance to researchers, policy makers, clinicians and employers, with wider implications for the revision of current psychosocial policy and practice.

Background. Recommendations in clinical practice guidelines for non-specific low back pain (NSLBP) are not necessarily translated into practice. Multiple research studies have investigated different strategies to implement best evidence into practice yet no synthesis of these studies is available. Objectives. To systematically review available studies to determine whether implementation efforts in this field have been successful; to identify which strategies have been most successful in changing healthcare practitioner behaviours and patient outcomes. Methods. A systematic review was undertaken, searching electronic databases, hand searching, writing to key authors and using prior knowledge of the field to identify papers. Included papers evaluated a strategy to implement best evidence about management of NSLBP into practice; measured key outcomes regarding change in practitioner behaviour/patient outcomes and subjected their data to statistical analysis. The Cochrane Effective Practice and Organisation of Care (EPOC) recommendations about data extraction and synthesis were followed. Study inclusion, data extraction and study risk of bias assessments were conducted independently. Results. Of 7654 potentially eligible citations, 17 papers reporting on 14 studies were included. Single/one-off implementation efforts were consistently unsuccessful. Increasing the frequency and duration of strategies led to greater success with those continuously ongoing over time the most successful. Risk of bias was highly variable with 7 of 17 papers rated at high risk. Conclusions. One-off implementation strategies may seem attractive but are largely unsuccessful in effecting meaningful change in practice. Increasing frequency and duration of strategies results in greater success and the most successful implementation strategies use consistently sustained interventions

Background Context. SPECT-CT is a hybrid imaging modality, which has become very well established in the diagnosis of inflammatory, vascular and malignant processes affecting the spine. However, little evidence exists on its application with degenerative pathologies. Purpose & Study Design. Systematic review on the use of SPECT-CT in the diagnosis of degenerative facet joint arthropathy. Patient Sample. 824 patients across 10 studies conducted over the last 6 years (2012 – 2018), with a mean age of 51.8 years old. All studies excluded patients with malignancy, infection or inflammatory aetiologies or those related to acute trauma. Only degenerative pathologies of the lumbar spine in an adult population were included. Methods. A systematic review of the literature available on the topic was conducted using the PubMed, Cochrane, Medline and Embase online databases of journal articles. Results. Five studies focused on SPECT-CT alone / versus CT. Two focused on SPECT-CT vs MRI, and three focussed on SPECT-CT guided facet joint injections. Of these 10 studies, seven concluded with results supporting SPECT CT's use, two reported discordance between SPECT-CT findings with those diagnosed from clinical examination / MRI scans, and one study's conclusions were equivocal. Conclusion. SPECT-CT shows promise as an imaging adjunct in assisting with the diagnosis and subsequent treatment of degenerative facet joint arthropathies. In patients whose MRI scans reveal multiple potential pain generators, SPECT-CT could help differentiate between clinically significant sources of pain and may even serve a purpose in guiding facet joint injections in patients with inconclusive MRI / CT scans.

Study design. Literature review of the best available evidence on the accuracy of computer assisted pedicle screw insertion. Background. Pedicle screw misplacement rates with the conventional insertion technique and adequate postoperative CT examination have ranged from 5 to 29 % in the cervical spine, from 3 to 58 % in the thoracic spine, and from 6 to 41% in the lumbosacral region. Despite these relatively high perforation rates, the incidence of reported screw-related complications has remained low. Interestingly, the highest rates of neurovascular injuries have been reported from the lumbosacral spine in up to 17% of the patients. Gertzbein and Robbins introduced a 4-mm “safe zone” in the thoracolumbar spine for medial encroachment, consisting of 2-mm of epidural and 2-mm of subarachnoid space. Later, several authors have found the safety margins to be significantly smaller, suggesting that the “safe zone” thresholds of Gertzbein and Robbins do not apply to the thoracic spine, and seem to be too high even for the lumbar spine. The midthoracic and midcervical spine, as well as the thoracolumbar junction set the highest demands for accuracy in pedicle screw insertion, with no room for either translational or rotational error at e.g. T5 level. Computer assisted pedicle screw insertion (navigation) was introduced in the early 90's to increase the accuracy and safety of pedicle screw insertion. Material. PubMed literature search revealed two randomized controlled trials (RCT) comparing the in vivo accuracy of conventional and computer assisted pedicle screw insertion techniques. Three meta-analyses have assessed the published reports on the accuracy of pedicle screw insertion with or without computer assistance, one additional meta-analysis concentrated on the functional outcome of computer assisted pedicle screw insertion. Results. The RCTs by Laine et al and Rajasekaran et al achieved significantly higher screw placement accuracy with computer assistance than with the conventional techniquebased on anatomical landmarks. In a degenerative patient population, Laine et al reported a misplacement rate of 4.6% with computer assistance compared to 13.4% with the conventional technique. In addition to this quantitative difference, a qualitative difference in the misplaced screws was noticed: in the conventional group, 28 out of 37 misplaced screws were either inferior or medial, whereas in the computer assisted group, 1 out of 10 misplaced screws was situated in these ”danger zones”. In deformity surgery, Rajasekaran et al reported a 2% pedicle screw misplacement rate with a computer assisted technique compared to 23% with the conventional technique. Interestingly, in their study, the average screw insertion time in the computer assisted group was significantly shorter than with the conventional technique. The three meta-analyses, assessing up to 37 337 pedicle screws, reported significantly higher accuracy in the placement of pedicle screws with computerassistance compared with the conventional methods. The superiority of the computer assisted technique was even more obvious with abnormal surgical anatomy. CT-based and 3D-fluoroscopy-based navigation methods provided better accuracy compared to 2Dfluoroscopy-based navigation. No statistically significant benefit with computer assistance in the incidence of neuro-vascular complications, or in functional outcome was demonstrated. Conclusion. High pedicle screw misplacement rates have been reported with the conventional technique based on anatomical landmarks and intraoperative fluoroscopy. The concept of ”safe zone” is hypothetical, and underestimates the true risks of misplaced pedicle screws. Computer assistance significantly improves the accuracy and safety of pedicle screw insertion. It will, however, be difficult to correlate this increased accuracy to improved patient outcomes


Background and purpose of the study. Dropped Head Syndrome (DHS) is characterized by a chin on chest flexion neck deformity that is passively correctible. The condition is rare and literature on surgical and conservative management is focused on case studies and theoretical evidence. Purpose of the study. The purpose of this study was to investigate the value of physiotherapy in the treatment of DHS by case series analysis. Methods. The effectiveness of physiotherapy was examined in six patients, some of whom were still under treatment and evaluation. Photographs were taken of some of the patients in order to gain further insight into the condition. Conservative management was provided in the form of physiotherapy and the use of a collar. Physiotherapy treatment involved a focus on sagittal balance and treatment included education, manual therapy, exercises, postural and mirror work and modification of sitting and lying positions. Results. In the first completed case study the patient reported an improvement in the ability to correct their deformity and improved appearance following physiotherapy. Photographs taken before and after treatment appear to support this. At one year follow up this patient still followed the advice given and did the exercises taught and reported to find them beneficial in managing DHS. The same approach was applied with the other patients in the case series with treatment and analysis evolving as further insight into the condition was gained. Conclusion. The case series supports other reported cases in the literature which report benefit from the use of physiotherapy as well as raising questions around the potential causes and management of DHS.

Introduction. Studies of the vestibular system in patients with idiopathic scoliosis (IS) have shown abnormalities in the semicircular canals (SCC) and the basicranium. Rousie (2008) revealed a statistically increased incidence of structural anomalies in the SCCs with three-dimensional computer generated modelling. Some of these findings were replicated in a small population by Cheng (2010). The primary goals of this investigation are verification of SCC abnormalities of patients with IS versus controls with use of three-dimensional modelling with subsequent development of a unique phenotypical classification. Our long-term goal is to provide new direction for hypothesis directed identification and characterisation of genes causally related to IS. Methods. 20 patients with IS and 20 controls matched for age and sex will be identified through the clinic with approval from the institutional review board. Power analyses were done to detect the difference in distributions as the proportion of fisher tests with p values less than 0·05. A sample size of 20 per group gives 86–99% power to realise results under conservative assumptions. IS patients and controls undergo vestibular system examination via T2 MRI imaging. Extracted data are evaluated by a team including Dr Rousie, ENT, radiology, and orthopaedic surgery. DNA is extracted with Gentra Puregene kits from Qiagen (Valencia, CA, USA). Developmental genes related to SCC and axial somatogenesis are being identified through a bioinformatics approach, targeting known IS genomic loci. Custom single-nucleotide polymorphism panels, statistical linkage, and association will identify genes of significance for sequencing. Results. To date, 11 patients with IS and four controls have been recruited. Preliminary data are indicative of a significant percentage of abnormalities within the SCC system in children with IS. Analyses of preliminary findings continue according to the protocol. Conclusions. Research into genetic factors predicting IS progression and/or magnitudes of curvature have been inconclusive. Whether these abnormalities are primary or secondary to a larger systemic issue is speculative; however, they demonstrate a potential new phenotypical classification. Our initial findings show evidence of SCC abnormalities in patients with IS in a well defined patient population compared with healthy controls. Ultimately, our goal for this project is to pursue investigations of genes, pseudogenes, and conserved sequences shown to be related to vestibular structural formation during embryogenesis and development. The identification of a subset of individuals with IS and vestibular abnormalities will allow for the study of genes involved concomitantly in the embryological development of both systems, thus providing insight into the inter-relationship of these deformities

Aims/background. Current treatment recommendations advocate various exercise modalities for people with chronic Low Back Pain (cLBP). 1. Walking appears to represent an inexpensive and readily accessible activity for a range of individuals, including those who were previously sedentary. However, the effectiveness of such interventions are uncertain in cLBP. Methods. A systematic review was undertaken to examine the effectiveness of walking interventions across a range of chronic musculoskeletal pain conditions, including LBP. Six electronic databases were searched for relevant studies. Data for pain and self reported function were extracted and where appropriate, results were pooled and analysed using RevMan (v.5). Results. Twenty studies with a total of 1852 participants (Mean: 96) were included in the review. Only two provided data for cLBP, Data from one of these was not analysed as only median values were reported. The remaining study found no effect in favour of the walking intervention for pain (mean difference = −0.50 [95% confidence interval = −16.23, 17.23]) with a moderate improvement in function (−22.56 [−40.84, −4.26]). For osteoarthritis, analysis revealed small to moderate differences for both pain (−6.23 [−11.22, −1.24]; n=7) and function (−10.90 [−20.61, −1.19]; n=5). Discussion. Despite the potential benefits associated with walking, results of this systematic review found limited evidence to support the use of such interventions for people with cLBP. Further studies where walking is the predominant component of an overall intervention and which closely monitor any associated adverse events are required

Study Purpose

To review systematically review literature on the early diagnosis of spinal metastases and prediction of spinal cord compression (SCC) due to spinal metastases

Methods and results

From 13 electronic bibliographic databases were searched we identified 2,425 potentially relevant articles of which 31 met the inclusion criteria. These were quality appraised. Seventeen studies reported retrospective data, 10 were prospective studies, and three were other study designs. There was one systematic review. There were no randomised controlled trials. There were approximately 7,900 participants in the included studies and 5,782 participants were analysed. The sample sizes ranged from 41 to 859. Cancers reported were: lung alone (n=3); prostate alone (n=6); breast alone (n=7); mixed cancers (n=13); and unclear (n=1). Ninety-three prognostic factors were identified as potentially significant in predicting risk of SCC or collapse. Many of the included studies provided limited information about patient population and selection criteria and they varied in methodological quality, rigour and transparency. Several studies with mixed case populations identified type of cancer (e.g. breast, lung or prostate cancer) as a significant factor in predicting SCC, but determining the risk differential is difficult because of residual bias in studies. Overall the quality of the research was poor. The only predictors identified for SCC were number of spinal metastases, duration of disease, total disease burden and immediate symptomatology of cord involvement.

Purpose and background

Although low back pain (LBP) with leg pain, is considered by most a poor prognostic indicator, it is at the same time believed to have a favourable natural resolution, and is often treated along similar lines to non-specific LBP, in line with current guidelines. It is unclear whether patients with LBP and leg pain are a distinct subgroup that might benefit from early identification and targeted interventions. We set out to investigate the impact of LBP with leg pain on health outcomes and health resources compared with that of LBP alone, and to explore which factors contribute to the observed disability outcomes.

Methods

A systematic literature search of all English language peer reviewed publications was conducted using Medline, EMBASE, and CINAHL for the years 1994 to 2009.

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. Methods. 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. Results. Torsion index (TI) and apical vertebral rotation (AVR) were identified as accurate predictors of curve progression in early visits. Initial TI > 3.7° and AVR > 5.8° were predictive of curve progression. Thoracic hypokyphosis was inconsistently observed in progressive curves with weak evidence. While sagittal wedging was observed in mild curves, there is insufficient evidence for its correlation with curve progression. In curves with initial Cobb angle < 25°, Cobb angle was a poor predictor for future curve progression. Prediction accuracy was improved by incorporating serial reconstructions in stepwise layers. However, a lack of post-hoc analysis was identified in studies involving geometrical models. Conclusion. For patients with mild curves, TI and AVR were identified as predictors of curve progression, with TI > 3.7° and AVR > 5.8° found to be important thresholds. Cobb angle acts as a poor predictor in mild curves, and more investigations are required to assess thoracic kyphosis and wedging as predictors. Cumulative reconstruction of radiographs improves prediction accuracy. Comprehensive analysis between progressive and non-progressive curves is recommended to extract meaningful thresholds for clinical prognostication. Cite this article: Bone Jt Open 2024;5(3):243–251

Aims. 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. Methods. 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. Results. After abstract and full-text screening, 205 out of 216 articles were excluded. The 11 included studies all reported occurrence of curve regression among AIS patients who were braced. Regression rate ranged from 16.7% to 100%. We found evidence that bracing is effective in achieving curve regression among compliant AIS patients eligible for bracing, i.e. curves of 25° to 40°. A similar effect was also found in patients with major curve sizes ranging from 40° to 60° when combined with scoliosis-specific exercises. There was also evidence showing that a low apical vertebral body height ratio, in-brace correction, smaller pre-brace Cobb angle, and daily pattern of brace-wear compliance predict curve regression after bracing. Conclusion. Bracing provides a corrective effect on scoliotic curves of AIS patients to achieve curve regression, given there is high compliance rate and the incorporation of exercises.

Background. A local authority approached us, for a cost-beneficial solution to their increasing low back pain referrals. We proposed developing a student-led clinic – an intervention delivered by students but supervised by clinicians. We then conducted scoping reviews on student-led clinics in the management of health conditions and on the self-management of back pain. The findings suggested that student-led self-management interventions for low back health should be feasible. The next step was to co-construct the intervention with key stakeholders. Co-Construction. A hybrid of Action Research and Design Science methodology was used to co-construct the intervention with five key stakeholder groups (council staff, managers and human resources, employee healthcare, students, and lecturers). Three rounds of focus groups explored the ‘problem’, the possible solutions, the process, and the content. Themes were taken from each of these focus groups and the similarities and differences were analysed. This analysis and subsequent synthesis with the evidence base created potential intervention models, which were discussed and refined with the stakeholder groups. Intervention. The proposed intervention is focused on providing evidence informed biopsychosocial support for work-relevant back pain, based on identifying obstacles and solutions to improve coping with back health at work. An onboarding workshop challenges positively their thinking around back pain and work. This is followed by up to three 1:1 sessions that support the individual to identify work-relevant back health goals and agree a plan to achieve them using techniques to facilitate behaviour change. Conclusion. The intervention is evidence informed and aims to address the prioritised needs of the stakeholders. Conflicts of interest. No conflicts of interest. Sources of funding.

Aims. 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). Methods. 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. Discussion. The primary outcome is ‘treatment failure’ (Cobb angle progression to 50° or more before skeletal maturity); skeletal maturity is at Risser stage 4 in females and 5 in males, or ‘treatment success’ (Cobb angle less than 50° at skeletal maturity). The comparison is on a non-inferiority basis (non-inferiority margin 11%). Participants are followed up every six months while in brace, and at one and two years after skeletal maturity. Secondary outcomes include the Scoliosis Research Society 22 questionnaire and measures of quality of life, psychological effects of bracing, adherence, anxiety and depression, sleep, satisfaction, and educational attainment. All data will be collected through the British Spine Registry. Cite this article: Bone Jt Open 2023;4(11):873–880

Background. 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. Methods. 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. Results. 2726 citations were identified; 11 studies were eligible. Overall study quality was low with all judged to have moderate or high risk of bias. Forty-five prognostic factors were identified but were measured inconsistently. The most commonly assessed prognostic factors were related to pain and function (n=7 studies), imaging features (n=6 studies), health and lifestyle (n=5 studies), patient demographics (n=4 studies) and clinical assessment findings (n=4 studies). No prognostic factor was found to be consistently associated with outcomes following ESI. Most studies found no association or results that conflicted with other studies. Conclusions. There is little, and low quality, evidence to guide practice in terms of factors that predict outcomes in patients following ESI for disc-related sciatica. The results can help inform some of the decisions about potential prognostic factors that should be assessed in future well-designed prospective cohort studies. Conflicts of interest: No conflicts of interest.

A Core Outcome Set (COS) for treatment of adolescent idiopathic scoliosis (AIS) is essential to ensure that the most meaningful outcomes are evaluated and used consistently. Measuring the same outcomes ensures evidence from clinical trials and routine clinical practice of different treatments can be more easily compared and combined, therefore increasing the quality of the evidence base. The SPINE-COS-AYA project aims to develop a gold standard COS which can be used internationally in research and routine clinical practice to evaluate the treatment (surgical and bracing) of AIS. In this qualitative study, the views of adolescents and young adults with AIS (10-25 years of age), their family members and healthcare professionals in a UK region were sought, via interviews, on treatment outcomes. Participants were purposively recruited from a variety of sources including NHS outpatient clinics and social media. Semi-structured interviews were analysed using thematic analysis. Key findings will be presented, to include potential core outcome domains identified by the different subgroups. The core outcome domains identified in this research programme will subsequently form part of an international consensus survey to agree a COS. In future, if the COS is used by healthcare staff and researchers, it will be easier for everyone, including patients and their families, to assess which treatment works best
