Aims. Patients with cauda equina syndrome (CES) require emergency imaging and surgical decompression. The severity and type of symptoms may influence the timing of imaging and surgery, and help predict the patient’s prognosis. Categories of CES attempt to group patients for management and prognostication purposes. We aimed in this study to assess the inter-rater reliability of dividing patients with CES into categories to assess whether they can be reliably applied in clinical practice and in research. Methods. A literature review was undertaken to identify published descriptions of categories of CES. A total of 100 real anonymized clinical vignettes of patients diagnosed with CES from the Understanding Cauda Equina Syndrome (UCES) study were reviewed by consultant spinal surgeons, neurosurgical registrars, and medical students. All were provided with published category definitions and asked to decide whether each patient had ‘suspected CES’; ‘early CES’; ‘incomplete CES’; or ‘CES with urinary retention’. Inter-rater agreement was assessed for all categories, for all raters, and for each group of raters using Fleiss’s kappa. Results. Each of the 100 participants were rated by four medical students, five neurosurgical registrars, and four consultant spinal surgeons. No groups achieved reasonable inter-rater agreement for any of the categories. CES with retention versus all other categories had the highest inter-rater agreement (kappa 0.34 (95% confidence interval 0.27 to 0.31); minimal agreement). There was no improvement in inter-rater agreement with clinical experience. Across all categories, registrars agreed with each other most often (kappa 0.41), followed by medical students (kappa 0.39). Consultant spinal surgeons had the lowest inter-rater agreement (kappa 0.17). Conclusion. Inter-rater agreement for categorizing CES is low among clinicians who regularly manage these patients. CES categories should be used with caution in clinical practice and research studies, as groups may be heterogenous and not comparable. Cite this article: Bone Joint J 2023;105-B(9):1007–1012

Background. 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. Methods. 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. Results. The majority of MDT discussions were for a surgical opinion (n=293, 25% clinician led, n=351, 30% patient led). Of these, 46% (n=135) of clinician surgical opinions were directly listed compared to 20% (n=70) of patient led discussions. Similar rates of consultant clinic review were seen between the two groups (22% and 32%), suggesting that the majority of patients discussed for surgical consideration were appropriate. 517 (45%) were discussed for management opinion. Conclusions. This evaluation demonstrates that a majority of cases (68%) identified by ASPPs for surgical opinion were either directly listed or had consultant clinic surgical review. The results and trends identified will guide future patient pathway development and ASPP training. Conflicts of interest: No conflicts of interest. Sources of funding: No sources of funding

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. Method and Results. 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. Conclusion. APP-led AIS clinics can provide similar levels of management and assessment as Spinal Consultants with improved waiting times and high levels of satisfaction. Conflicts of interest: No conflicts of interest. Sources of funding: No funding obtained

Aims. The aim of this study was to assess the reliability of using MRI scans to calculate the Spinal Instability Neoplastic Score (SINS) in patients with metastatic spinal cord compression (MSCC). Methods. A total of 100 patients were retrospectively included in the study. The SINS score was calculated from each patient’s MRI and CT scans by two consultant musculoskeletal radiologists (reviewers 1 and 2) and one consultant spinal surgeon (reviewer 3). In order to avoid potential bias in the assessment, MRI scans were reviewed first. Bland-Altman analysis was used to identify the limits of agreement between the SINS scores from the MRI and CT scans for the three reviewers. Results. The limit of agreement between the SINS score from the MRI and CT scans for the reviewers was -0.11 for reviewer 1 (95% CI 0.82 to -1.04), -0.12 for reviewer 2 (95% CI 1.24 to -1.48), and -0.37 for reviewer 3 (95% CI 2.35 to -3.09). The use of MRI tended to increase the score when compared with that using the CT scan. No patient having their score calculated from MRI scans would have been classified as stable rather than intermediate or unstable when calculated from CT scans, potentially leading to suboptimal care. Conclusion. We found that MRI scans can be used to calculate the SINS score reliably, compared with the score from CT scans. The main difference between the scores derived from MRI and CT was in defining the type of bony lesion. This could be made easier by knowing the site of the primary tumour when calculating the score, or by using inverted T1-volumetric interpolated breath-hold examination MRI to assess the bone more reliably, similar to using CT.

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. Methods & Results. 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). Discussion. These results have made it evident that there is a need for improvement to our current CES pathway at all levels. Our current system is overloaded with poor referrals that backlog the MRI scanner, leading to delays. Providing training for referrers in the first instance may improve things, however a more thorough overhaul of the pathway is required. Conflicts of interest: No conflicts of interest.

INTRODUCTION. The correct placement of pedicle screws is a major part of spine fusion and it requires experienced trained spinal surgeons. In the era of European Working Time Directive (EWTD), surgical trainees have less opportunity to acquire skills. Josh Kauffman (Author of The First 20 Hours) examined the K. Anders-Ericsson study that 10,000 hours is required to be an expert. He suggests you can be good at anything in 20 hours following 5 methods. This study was done to show the use of accelerated learning in trainees to achieve competency and confidence on the insertion of pedicle screws. METHODS. Data was collected using 3 experienced spine surgeons, 8 trainees and 1 novice (control) on the cadaveric insertion of pedicle screws over a 4 day didactic lecture in the cadaver lab. Each candidate had 2 cadavers and 156 screw placements over 4 hour shifts. Data was collected for time of pedicle screw insertion for each level on the left and right side. A pre-course and post-course questionnaire (Likert scale) was conducted. RESULTS. There were 8 candidates (surgeons) involved. 1 spinal SpR, 6 spine fellows and 1 junior consultant. A physiotherapist was the control novice. The surgeons and the control got significantly faster over time. The control made significantly more errors than the surgeons. Surgeons were significantly faster by the end (p value < 0.05). The control got faster over time and by the end, was no longer significantly slower than the surgeon when they first started. CONCLUSION. Pedicle screw insertion can cause significant morbidity, which includes paralysis. As a trainee, this is not an easy skill to acquire or practice. This focused pedicle screw course shows that a junior spinal surgeon can achieve improved competency and confidence in 20 hours but furthermore a complete novice can learn to insert pedicle screws and reach a level of competence almost at the level of the trainee in 20 hours as well

Aims. Early cases of cauda equina syndrome (CES) often present with nonspecific symptoms and signs, and it is recommended that patients undergo emergency MRI regardless of the time since presentation. This creates substantial pressure on resources, with many scans performed to rule out cauda equina rather than confirm it. We propose that compression of the cauda equina should be apparent with a limited sequence (LS) scan that takes significantly less time to perform. Methods. In all, 188 patients with suspected CES underwent a LS lumbosacral MRI between the beginning of September 2017 and the end of July 2018. These images were read by a consultant musculoskeletal radiologist. All images took place on a 3T or 1.5T MRI scanner at Stoke Mandeville Hospital, Aylesbury, UK, and Royal Berkshire Hospital, Reading, UK. Results. The 188 patients, all under the age of 55 years, underwent 196 LS lumbosacral MRI scans for suspected CES. Of these patients, 14 had cauda equina compression and underwent emergency decompression. No cases of CES were missed. Patients spent a mean 9.9 minutes (8 to 10) in the MRI scanner. Conclusion. Our results suggest that a LS lumbosacral MRI could be used to diagnose CES safely in patients under the age of 55 years, but that further research is needed to assess safety and efficacy of this technique before changes to existing protocols can be recommended. In addition, work is needed to assess if LS MRIs can be used throughout the spine and if alternative pathology is being considered. Cite this article: Bone Joint J 2020;102-B(4):501–505

Purpose. A Virtual Spinal Clinic (VSC) was set-up at a regional spinal referral centre to see if patient care could be improved through early advice to provide timely management, early onward referral, improve patient satisfaction and minimise chronicity. The clinic was based on the successful virtual model used throughout the country within orthopaedic fracture clinics. VSC is a Consultant led multi-disciplinary (MDT) clinic run by Advanced Practitioners (AP). Methods. A 3-month trial of the VSC was completed bi-weekly. Patients diagnosed with conservatively managed spinal fractures were referred from the on-call service. A management plan was devised by a Consultant Spinal Surgeon and communicated to patients by the AP via a telephone-call consultation where clinical advice and management could be discussed. Results. 23 clinics completed. 271 patient contacts. 216 reviewed virtually. Completed outcomes of VSC. 34.65% Discharged. 51.18% Routine appointment. 14.17% Urgent appointment. Conclusion. VSC successfully completed safe and timely assessments, management plans, telephone consultations and onward referrals for Greater Manchester patients with acute spinal fractures. Patients had earlier access to health professionals to provide advice, reassurance, complete onward referrals and safety-netting. Patient satisfaction improved, with patient reporting the telephone consultation was reassuring and allowed early return to previous function. VSC reduced patients waiting time for a follow-up appointment and reduced patients travel time across Greater Manchester. In the future, it is hoped that the 6-week follow-up telephone call service will be utilised more as VSC develops. No conflicts of interest. No funding obtained

Objectives:. To establish the demand, referral pathways, utility and patient satisfaction of a physiotherapy led post operative spinal surgery review clinic. Methods:. From July 2014 to January 2015 a pilot physiotherapy led clinic was established. The following clinic data was collected: number of patients reviewed, surgical procedure, outcome of clinic assessment, numbers requiring further investigation, numbers requiring review in the consultant led clinic and adverse events. A patient satisfaction survey was also administered to all English speaking patients. Patients were asked to rate the ease of getting through to the service by phone, length of wait, time spent with the clinician, answers to questions, explanation of results, advice about exercise and return to activities, the technical skills of the clinician, their personal manner and their overall visit. Data was anonymised and inserted into an excel spreadsheet for analysis. Descriptive statistical analysis was undertaken. Results:. 28 patients were reviewed in the pilot clinic. 17 (61%) patients were reviewed and discharged. 11 (39%) patients required discussion with the consultant. The outcome was: Referral for further imaging: n=5 (18%), referral to other specialist: n=2 (6%), consultant led OPD clinic review n=4 (14%) and surgical review of wound n=1 (4%). 84% (n=21/25) of eligible patients completed a post operative satisfaction survey. 86% (n= 18/21) rated their overall visit as excellent. There were no adverse events reported. Conclusion:. The pilot clinic has informed the development of a permanent physiotherapy led post op clinic in the National Neurosurgical Spinal Service and demonstrates the value of interdisciplinary care in this population

Different methods of lateral mass(LM) screw placement in the cervical spine have been described. In the axial plane, 30 degrees is the recommended angle to avoid neurovascular injury. The estimation of this angle remains arbitrary and operator dependant. To assess how accurately the lateral trajectory angle (LTA) for cervical LM screws is achieved by visual estimation amongst experienced spinal surgeons. A sawbone model of cervical spine with simulated lordosis was used. Five spinal consultants and five senior spinal fellows were asked to insert 1.6 mm K wires into lateral masses of C3 to C6 bilaterally to simulate screws. The LTA in transverse plane was measured using a customised protractor. Basic statistical analyses of all the data were obtained. Using all the angles derived, a virtual screw trajectory was drawn in the lateral plane, on a normal axial Computerised Tomography scan of cervical spine of an anonymous patient using PACS system. The overall mean LTA for the group was 25.15 degrees, that of the fellows 24.4 and consultants 26.2 degrees. Mean deviation from 30 degrees for fellows was 5.2 and 6.4 degrees for consultants. Overall standard deviation was 4.78, for fellows and consultants it was 3.3 and 5.8 respectively. Two episodes of vertebral artery injury occurred at 15 and 16 degrees with simulated angles on CT. A moderate variability in visual estimation of the trajectory angle exists even amongst experienced surgeons during insertion of cervical LM screws. An anatomical landmark would be useful to improve the reliability of the procedure

Introduction. The British Scoliosis Society published a document in 2008 which set out the minimum standards for paediatric spinal deformity services to achieve over a period of time. But how do the UK paediatric spinal deformity centres measure up to these benchmarks?. Methods. We performed a telephonic survey, contacting every UK spinal deformity centre. The questionnaire probed how each unit compared to the recommended standards. Results. Twenty three centres were interviewed, covering 81 surgeons in total (range 1-8 surgeons per centre). Four centres (17%) did not have 24-hour access to a MRI scanner and all but 2 centres had on-site facilities for long-cassette films/scoliograms. Five centres (22%) always had 2 consultant surgeons per case, 9 centres (39%) routinely have only 1 consultant surgeon per case, and the rest had 1 or 2 consultant surgeons depending on seniority. Six centres (26%) did not routinely have shared care of their patients with the paediatric team. All centres used intra-operative SSEP monitoring, a minority used MEP monitoring (34%), and all but 2 centres had either direct or indirect supervision by a consultant neurophysiologist. All centres have cell saver units available with over half using them routinely (14/23). None of the centres used routine chemoprophylaxis. All units used thromboembolic stockings, with five centres (22%) routinely using foot pumps. Nineteen centres (83%) routinely sent their spinal deformity patients to ITU/PICU postoperatively. Our survey also asked each center what supporting facilities were available, whether they ran adolescent clinics, and whether they participate in multi-disciplinary meetings and audit. In addition, we questioned what typed of drains each center used and the length of time that patients were followed-up. Conclusion. This survey shows how the UK spinal deformity units stand up against the BSS standards, provides an insight in to current UK practice and highlights areas for improvement

MRI scanning of spinal patients at the Primary Care Triage stage is pivotal in reducing inappropriate referrals into Secondary Care. A retrospective study was undertaken. Details of patients from spinal triage clinics referred for MRI scan were collated together with a provisional diagnosis. Following imaging the results and management plan were documented. 2191 Patients referred via GP's to Physiotherapy Specialist- lead spinal triage clinics from April to September 2009 inclusive. Referred to a spinal consultant routine/urgent, Managed conservatively, Failed to attend for MRI scanning or MRI cancelled, Sent for scanning for reassurance and discharged. Of 2191 patients seen in a 6-month period 194 (9%) were referred for MRI of which 81 (41%) were referred on to spinal consultant. This equates to 3.7% of the total number of patients triaged. Specialist physiotherapy diagnosticians with access to MRI scanning, allows simultaneous treatment and seamless transfer to spinal consultants for surgical intervention if appropriate. 1. This process is used effectively to manage large numbers of spinal referrals and minimises the number of patients seen unnecessarily in secondary care. 1. This is only possible with close multidisciplinary team working. 2.

We have examined how many and which potential complications (PCs) are recorded on the consent form by a group of consultant surgeons performing common spinal procedures - anterior cervical discectomy and fusion (ACDF) and posterior lumbar discectomy and/or medial facetectomy (PLD). Email survey. Consultant spinal surgeons performing ACDF and/or PLD practicing in Southwest England. Identification of the PCs each surgeon listed on the consent form for the specified procedures. There were 23 responses from 28 Consultant surgeons approached. 21 surgeons performed both ACDF and PLD, 2 performed only PLD. Surgeons quoted 5 to 17 (mode 10) PCs for ACDF and 4 to 15 (mode 13) for PLD. These did not necessarily represent the most common or most dangerous PCs recorded in the literature. 1,2. Small difference in PCs mentioned by Neurosurgeons and Orthopaedic surgeons was seen (ACDF mode: 12vs10, PLD mode: 12vs13). There was a strong correlation between the number of PCs recorded by surgeons for ACDF and PLD. We have found a wide variation in consenting practice amongst a group of surgeons performing common spinal operations. Issues of consent are common causes of formal complaints and potential litigation, causing anxiety for both patient and surgeon. A more homogenous consent process, employing objective measures where possible, may help reduce this burden and may be achieved by setting a national standard

Aims

To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation.

Aims

Psychoeducative prehabilitation to optimize surgical outcomes is relatively novel in spinal fusion surgery and, like most rehabilitation treatments, they are rarely well specified. Spinal fusion patients experience anxieties perioperatively about pain and immobility, which might prolong hospital length of stay (LOS). The aim of this prospective cohort study was to determine if a Preoperative Spinal Education (POSE) programme, specified using the Rehabilitation Treatment Specification System (RTSS) and designed to normalize expectations and reduce anxieties, was safe and reduced LOS.

Purpose. To compare the incidence and nature of ‘neurophysiological events’ identified, post hoc, by a consultant neurophysiologist with those identified intra-operatively by clinical physiologists, before and after intervention(s). Methods. The IOM wave-recordings, event-logs and reports of all spinal deformity cases conducted by a team of clinical physiologists from April to June 2009 (Group 1) were reviewed retrospectively by the same, experienced clinical neurophysiologist, (MG). Interventions were then agreed. The first was to alter the IOM report document to drop down menus. The second was to arrange a series of teaching sessions for the clinical physiologists on a variety of aspects of IOM. Finally during these teaching sessions recent cases were brought to review in an informal setting to discuss. Following implementation of the interventions a further review from April to June 2010 (Group 2) was carried out in the same manner. The clinical physiologists did not know the time periods over which the review would be taking place. Results. From April to June 2009 (Group 1) thirty two patients were studied and from April to June 2010 (Group 2) thirty four patients were studies. Group 1. Twenty seven of these had been monitored using ‘multimodal’ IOM consisting of cortical (CSEP) and spinal (SSEP) somatosensory evoked potentials and motor (MEP/CMAP) evoked potentials. Two patients were inappropriate for MEP recording and two were monitored using epidural SSEP recording. During 10 operations (31%) the surgeons were notified of an ‘intra-operative neurological event’ judged by the clinical neurophysiologist as potentially requiring a surgical response. When the results were audited, only 2 (6%) of these ‘events’ were considered by the consultant clinical neurophysiologist to represent ‘true positive’ intra-operative neurophysiological findings. Group 2. Twenty six of these had been monitored using ‘multimodal’ IOM consisting of cortical (CSEP) and spinal (SSEP) somatosensory evoked potentials and motor (MEP/CMAP) evoked potentials. Four patients were inappropriate for MEP recording and had a combination of SSEP and CSEP. The remainder had IOM with unimodal. No epidural IOM was used during this period. During 4 operations (12%) the surgeons were notified of an ‘intra-operative neurological event’ judged by the clinical neurophysiologist as potentially requiring a surgical response. Post-operative examination of all the patients in both groups revealed that no ‘false negative’ conclusions had been reached. Conclusion. In this series clinical physiologists were found to alert the surgeons 5 times more frequently than was likely to have been the case with an experienced consultant clinical neurophysiologist (31% and 6% respectively). However the increased reporting of intra-operative events did not result in any alteration of the ultimate surgical strategy in any operation although tactical changes were sometimes necessary during the operation in order to test the reversibility of the flagged event. The implementation of two simple interventions resulted in the clinical physiologists alerting the surgeons only 1/3 of that previously (12%) of cases. The log indicated that on all occasions appropriate surgical action had been taken with no residual neurological deficit. This study, owing to its size, cannot answer the key question of safety. Further work to estimate the statistical power required of such a study is being sought. In the interim proving a track record of successful cases provides evidence of efficacy. Ethics Approval: None. Interest Statement: None

Background. Previous research in people with musculoskeletal low back pain (MLBP) in primary care shows that a reliable and valid measure of consultation-based reassurance enables testing reassurance against patient' outcomes. Little is known about the role of reassurance in people with MLBP consulting spinal surgeons, especially in cases where surgeons recommend not to have surgery. There might be several reasons to exclude surgery as a treatment option, that range from positive messages about symptoms resolving to negative messages, suggesting that all reasonable avenue of treatment have been exhausted. AIM to explore patient's experience of consultation-based reassurance in people with MLBP who have been recently advised not to have surgery. Methods. Semi-structured interviews were conducted with 30 low back pain patients who had recently consulted for spinal surgery and were advised that surgery is not indicated. Interview were audio recorded and transcribed, and then coded using NVIVO qualitative software and analysed using the Framework Analysis. Results. Most patients reported feeling dismissed and discouraged. They considered that consultants were better in relationship building and data gathering than in providing cognitive and generic reassurance. Major emerging themes included the complexity and confusion of their NHS journey, lack of continuity-of-care, lack of information for their condition and a sense of dismissal. Patients reported that they needed reassurance through clear explanations and discussion of pain management, but instead were discharged into a void. Conclusion. Effective communication with patients attending surgical settings to consult about their back pain is important, especially when no active treatment is being offered. No conflict of interest.

Background. The BACK To Health programme is part of the wider North of England back pain and radicular pain pathway. The purpose of this programme is to provide a CPPP approach based on the NICE guidelines CG88 for those with back pain that has not responded to early management and simpler therapies. The purpose of this study is to present preliminary results of this programme. Method. Referral onto the programme occurred through triage and treat practitioners or consultant clinics. A total of 44 patients were referred, with 31 attending the programme. The programme was delivered as a 3 week residential programme, with patients present 9am-5pm Monday to Thursday. A MDT provided an intense programme consisting of education, physical exercise, practical coping strategies and group discussion. The work has received ethical approval from the School of Health and Social Care Research Ethics and Governance committee at Teesside University. Results. Significant improvements (p<0.05) were seen in the, EQ-5D-5L, GAD-7, PHQ9, pain VAS scores (respective mean improvement 0.170, 5.2, 5.5 and 1.25). Significant improvement (p<0.05) was seen in ODI scores but with a mean improvement of 7% clinical significance was not achieved. Self-management confidence by the end averaged 6/10. Conclusion. The majority of patients showed good response to the BACK To Health Programme. After undergoing 3 weeks of education and exercise using cognitive behavioural principles early improvements were seen in GAD-7, PHQ9, Pain VAS and EQ/5D/5L. At 6 months and 1 year we will follow these patients up to continually assess progress. No conflicts of interest. No funding obtained

Background. Low back pain (LBP) with or without leg pain, is one of the most common causes of pain and disability and a frequent cause of attendance to emergency departments (ED). Increasing numbers of patients create a difficult challenge for clinicians to effectively and appropriately manage patients with LBP in an urgent care setting. Purpose. To improve the management of atraumatic spinal pain patients admitted onto the emergency assessment unit (EAU) thus improving quality of care, reducing bed stay and facilitating appropriate discharge and follow-up within an interdisciplinary model. Method. From January 2014, consultant physiotherapists, led a 7-day service to assess and manage patients admitted to the EAU with atraumatic back pain. Patients are referred for appropriately and timely investigations. Non-medical prescribing skills allow physiotherapists to offer pharmacological review and prescribing in line with best practice guidelines. All care is delivered within a framework of inter-professional care with involvement of emergency medicine, spinal orthopaedic, neurosurgical, pain management and pharmacy teams. Results. Length of stay has reduced by 25% in two years (potential saving £411,726 per annum). Official patient complaints have reduced to zero. Readmission within 30 days has fallen from 1.2% of the total number of admissions with atraumatic back pain to 0.8% despite earlier discharge. Cost of bed stay has fallen from. Conclusion. Highly skilled physiotherapists are ideally placed to lead and deliver safe and effective care for patients presenting with atraumatic back pain within an urgent care setting. This has resulted in improved care at lower cost. No conflicts of interest. No funding obtained

Introduction. The usefulness of markers of non-specific low back pain (NSLBP), including MRI derived measurements of cross-sectional area (CSA) and functional CSA (FCSA, fat free muscle area) of the lumbar musculature, is in doubt. To our knowledge, such markers remain unexplored in Lumbar Disc Degeneration (LDD), which is significantly associated with NSLBP, Modic change and symptom recurrence. This exploratory 3.0-T MRI study addresses this shortfall by comparing asymmetry and composition in asymptomatic older adults with and without Modic change. Methods. A sample of 21 healthy, asymptomatic subjects participated (mean age 56.9 years). T2-weighted axial lumbar images were obtained (L3/L4 to L5/S1), with slices oriented through the centre of each disc. Scans were examined by a Consultant MRI specialist and divided into 2 groups dependent on Modic presence (M) or absence (NM). Bilateral measurements of the CSA and FCSA of the erector spinae, multifidus, psoas major and quadratus lumborum were made using Image-J software. Muscle composition was determined using the equation [(FCSA/CSA)*100] and asymmetry using the equation [(Largest FCSA-smallest FCSA)/largest FCSA*100]. Data were analysed using Mann-Whitney U tests (p value set at). Intrarater reliability was examined using Intraclass Correlations (ICCs). Results. ICCs ranged between 0.74 and 0.96 for all area measurements, indicating excellent reliability. There was no significant difference in TCSA and FCSA asymmetry (P=0.1–1.0) and muscle composition (P=0.1–1.0) between M and NM groups. Conclusion. Modic change in the absence of pain does not appear to influence cross-sectional asymmetry or composition of the lumbar musculature. CSA remains a controversial marker. No conflicts of interest.
