To review our practice of requesting nerve root blocks, to see how effective our therapeutic blocks are and how many of our diagnostic blocks confirm clinical suspicion and help decision making. Retrospective cohort analysis. 120 fluoroscopically guided nerve root blocks were performed between 20/08/2008 and 29/12/2008. There were 100 patients who had pain diary data available, 42 males (mean age 52.02 range 20-76) 58 females (mean age 60.03, range 22-88). We recorded: clinical diagnosis, reason for block, result of block on a 10 point visual analogue pain diary on days 0, 2, 14 and at review. A successful block was defined as an improvement of at least 2 points. For the diagnostic blocks we also recorded whether the block result influenced surgical decision making. Block methods will be illustrated in diagram. Results will be displayed graphically and in text. 18 blocks were cervical (1 purely diagnostic, 6 therapeutic, and 10 mixed, 1 data unavailable). 71 blocks were lumbar (1 purely diagnostic, 28 purely therapeutic, and 37 mixed, 5 data unavailable). 28% of all blocks were successful immediately (2 unavailable data) and 22% at two weeks (1 unavailable data). By 3 months the success rate for therapeutic blocks was 26%. Of the blocks done for diagnostic reasons, 86% influenced a clinical decision at the next outpatient appointment. Our results justify the continuance of this service. Increased care should be taken that patients' outcome data is collected

Few studies have examined the order in which a spinal osteotomy and total hip replacement (THR) are to be performed for patients with ankylosing spondylitis. We have retrospectively reviewed 28 consecutive patients with ankylosing spondylitis who underwent both a spinal osteotomy and a THR from September 2004 to November 2012. In the cohort 22 patients had a spinal osteotomy before a THR (group 1), and six patients had a THR before a spinal osteotomy (group 2). The mean duration of follow-up was 3.5 years (2 to 9). The spinal sagittal Cobb angle of the vertebral osteotomy segment was corrected from a pre-operative kyphosis angle of 32.4 (SD 15.5°) to a post-operative lordosis 29.6 (SD 11.2°) (p < 0.001). Significant improvements in pain, function and range of movement were observed following THR. In group 2, two of six patients had an early anterior dislocation. The spinal osteotomy was performed two weeks after the THR. At follow-up, no hip has required revision in either group. Although this non-comparative study only involved a small number of patients, given our experience, we believe a spinal osteotomy should be performed prior to a THR, unless the deformity is so severe that the procedure cannot be performed.

To assess how effective are the prognostic scores and the role of delayed presentation in predicting the outcomes in patients with metastatic spine disease.

Retrospectively data collected from December 2006 to December 2009. Medical records review included types of tumours, duration of symptoms, duration from referral to definitive treatment, expected survival, functional status before and after treatment. Karnofsky performance score and Modified Tokuhashi were used.

Results: 50 patients underwent surgical stabilisation for metastatic spine disease with or with out cord compression. Age ranged from 39 to 87 years (Avg: 64). Patients had four main types of tumours; (Myeloma 30%, Lymphoma 22% Lung CA 16% and Renal 12 %).

Inpatients without cord compression, the average time from referral to definitive treatment is 17 days. Over all fictional status improved in 70% of cases following surgical intervention. Patients who presented with cord compression had surgery with in 49 hours. Patients with high prognostic scores did not survive as long as expected. On the contrary, patients with poor prognostic scores survived longer than expected. This discrepancy is significant in patients with lung and renal malignancies. Patients with Myeloma did well as per the prognostic scores.

Prognostic scores are not uniformly effective in all types of malignancies. Factors like delayed presentation and general condition were not included in the prognostic factors. Hence, we conclude that we cannot make a decision purely based on the prognostic scores to perform either palliative or definitive surgery.

Statement of purpose of study and background. As the treatment of low back pain (LBP) continues to evolve, there is greater recognition of the importance of optimising the therapeutic relationship to better deliver improved patient outcomes. Contextual effects, such as communication, have been shown to influence the therapeutic relationship, but it is not known how these factors evolve over time. This study analysed interviews from two studies (one cross-sectional and one longitudinal) to explore patients’ and physiotherapists’ perspectives of treatment outcomes and experiences in episodes of LBP in the same dialogic space. The objective was to explore the alignment between these perceptions to identify factors that influence the therapeutic relationship over time. Summary of methods used and results. Two secondary thematic analyses were undertaken, one analysing cross-sectional data and the other analysing longitudinal data, from an existing data set from the programme: “Exploring the relationship between communication and clinical decision-making in physiotherapy consultations for back pain”. All data were thematically analysed and organised using a framework approach. Six themes emerged from the cross-sectional data reporting consistency of opinion in the initial consultation stages, but highlighting inadequate patient involvement in shared decision making. Four main themes emerged from the longitudinal data, all of which reported interactional fears and anxieties identified on both the parts of the patient and the physiotherapist. Conclusion. These findings suggest that failing to involve the patient in adequately personalised treatment from the initial consultation may lead to diagnosis hunting and stereotyping behaviours within the therapeutic relationship, in turn leading to increased health resource usage.

Modern techniques facilitate the treatment of adult spinal deformity. Decision making is a challenge because of potential complications relating to the surgery itself and medical problems. This study aims to provide useful data in facilitating the decision making process. Retrospective analysis of consecutive single surgeon series of patients aged >50 between 2006-2009 undergoing multi-level spinal deformity surgery with concomitant decompression. Medical co-morbidities, age and ASA were recorded. 71 patients (57 female) mean age 66 (50-83). 29 (12 multiple) failed previous stenosis surgery. 14(19.7%) in hospital complications in 11(15.5%) patients. 4 were ‘medical’. 8/11 patients were revision cases versus 3/11 primary. 4 patients (5.6%) needed further surgery. 13(18.3%) outpatient complications in 12(16.9%)patients. 7/12 occurred in revision cases versus 5/12 in primary. 11(15.5%) needed further surgery. Revisional surgery in adult deformity presents a significantly higher overall complication rate than primary surgery (p= 0.0084), but both revisional and primary cases have a relatively high re-operation rate once initially discharged. The results indicate that complex medical and surgical factors contribute to the decision making challenge in patients with adult spinal deformity and stenosis

Background. The available treatments for NSLBP (Non-Specific Low Back Pain) provide, typically, small to moderate average benefits to patients. The aim of this pilot cluster RCT was to test the hypothesis that the use of a patient decision aid together with an informed shared decision making consultation would produce better outcomes in satisfaction with treatment at four month follow-up. Methods. We developed a DSP (Decision Support Package). We randomised the physiotherapists and trained those in the intervention arm in informed shared decision making and communication. Participants were recruited from a local physiotherapy department and those allocated to an appointment with an intervention therapist were sent a copy of the DSP in the post. Participants then attended their appointment as usual. Results. We recruited 148 participants, 85 (57%) participants were assigned to the DSP arm. There was an 80% response rate for the primary outcome, satisfaction with treatment. The adjusted odds ratio of satisfaction with treatments from participants in the DSP arm against those in the control arm was 0.54 (95% CI: 0.19, 1.53). The difference between the treatment arms for the RMDQ (Roland Morris Disability Questionnaire) at four month follow-up was −2.27 (95% CI: −4.47, −0.08). Conclusions. There were no differences in our primary outcome measure between the groups. There was a statistically significant and clinically important difference in the RMDQ. These data have informed our decision about progression to a full trial application

Background. Evidence-based practice advocates utilising best current research evidence, while reflecting patient preference and clinical expertise in decision making. Successfully incorporating this evidence into practice is a complex process. Based on recommendations of existing guidelines and systematic evidence reviews conducted using the GRADE approach, treatment pathways for common spinal pain disorders were developed. Aims. The aim of this study was to identify important potential facilitators to the integration of these pathways into routine clinical practice. Methods. A 22 person stakeholder group consisting of patient representatives, clinicians, researchers and members of relevant clinical interest groups took part in a series of moderated focus groups, followed up with individual, semi-structured interviews. Data were analysed using content analysis. Results. Participants identified a number of issues which were categorized into broad themes. Common facilitators to implementation included continual education and synthesis of research evidence which is reflective of everyday practice; as well as the use of clear, unambiguous messages in recommendations. Meeting additional training needs in new or extended areas of practice was also recognized as an important factor. Different stakeholders identified specific areas which could be associated with successful uptake. Patients frequently defined early involvement in a shared decision making process as important. Clinicians identified case based examples and information on important prognostic indicators as useful tools to aiding decisions. Conclusion. A number of potential implementation strategies were identified. Further work will examine the impact of these and other important factors on the integration of evidence-based treatment recommendations into clinical practice

Purposes and Background. Musculoskeletal disorders are leading causes of work disability. Our purpose was to develop a predictive model in a cohort from 2012 and validate the model in 2016 data. Methods and Results. Prospectively collected data was used to identify inception cohorts in 2012 (n=1652) and 2016 (n=199). Data from back pain claimants receiving treatment in physiotherapy clinics and the Ontario workers' compensation database were linked. Patients were followed for 1 year. Variables from a back pain questionnaire and clinical, demographic and administrative factors were assessed for predictive value. The outcome was cumulative number of calendar days receiving wage-replacement benefits. Cox regression revealed 8 significant predictors of shorter time on benefits in the 2012 cohort: early intervention (HR=1.51), symptom duration < 31 days (HR=0.88), not in construction industry (HR=1.89), high Low Back Outcome Score (HR=1.03), younger age (HR=0.99), higher benefit rate (HR=1.00), intermittent pain (HR=1.15), no sleep disturbance (HR=1.15). The 2012 model c-statistic was 0.73 with a calibration slope of 0.90 (SE=0.19, p=0.61) in the 2016 data, meaning not significantly different. The c-statistic in the 2016 data was 0.69. Median duration on benefits of those with a high risk score was 129 days in 2012 and 45 days in 2016. Conclusion. The 2012 model had a good fit and calibrated well in the 2016 data. Changes in case management by the WSIB might have resulted in significant differences between the 2012 and 2106 cohort. The difference in duration on benefits could affect treatment decision making in future. Conflicts of interest: IWH is funded by the Ministry of Labour in Ontario.

Purpose and background. A review of secondary healthcare provision for civilians suffering persistent pain and living in the British Forces Germany (BFG) community was carried out in order to better inform referral from primary care. This population consists mostly of British nationals each with differing linguistic skills and cultural backgrounds. Patients may be referred to Evangelisches Krankenhaus Bielefeld (EvKB) in Germany or to Guys and St Thomas' NHS Foundation Trust (GSTT) in the UK. It was considered important to identify potential language or cultural-related barriers to improve decision making when considering where best to refer for a pain management programme (PMP). Methods. Clinical visits undertaken at GSTT and EvKB involved observation of clinical activities, collection of documentation and informal staff discussions. Data were organised into common themes and categorised to provide information for written reflective accounts on each visit. Results. The PMP at EvKB is medical doctor-led, supported by integrated psychologists. English language skills of individual staff members appear varied. Patients stay in shared rooms on a medical ward environment. Group based pain education here is provided in German only. Access to the GSTT PMP requires competent English language skills. It is psychologist-led and delivered by an interdisciplinary team. Patients reside in individual living accommodation and attend group therapy sessions. Conclusion. To reduce risk of increasing anxiety, cultural differences related to language, medical hierarchy and privacy should be considered before referring non-German speakers with complex psychosocial needs to EvKB. Given the complexity of pain, non-native speakers may misunderstand translations of cultural nuances used in pain education. No conflicts of interest.

Introduction. Morphological parameters are used to describe curve characters in AIS like curve location, curve magnitude, stiffness etc. Like all other morphological metrics the accuracy is more when digital imaging, archiving and extraction of features is used rather than manual measurements. The content Based Image Retrieval system is anew software that allows rapid, accurate documentation of AIS images and their retrieval by visual content. Classification systems and their shortcomings. Traditional classifications only looked at curve location (Ponsetti/Friedman); this was enhanced to add curve flexibility (to include or exclude secondary curves in fusion) (PUMC, King/Moe etc). Newer classifications like the Lenke have added sagittal profile into the decision making equation. From 5 basic curve types the subtypes have increased to 42 potential curve patterns by the addition of one parameter!! In future as we understand the 3-D geometry of these curves better we may want to add more measureable items (like degree of rotation) and by adding one term the subtypes would be 128!!! This suggests that we need to have a simple easy to remember way of classifying or eliminate classifications altogether. Experimental evidence. Several experiments were conducted with the new CBIR software which showed that similar images of scoliosis cases could be retrieved without resorting to a classification scheme. Even surgical planning can be made by downloading all similar cases operated before. The variability can be set to any level of precision desired. Significance. In future we may eliminate classifications to decide on curve types and for surgical planning and recall from a large multicentre database similar curves and their surgical plan

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).

Aims

The purpose of this study was to evaluate the incidence and analyze the trends of surgeon-reported complications following surgery for adolescent idiopathic scoliosis (AIS) over a 13-year period from the Scoliosis Research Society (SRS) Morbidity and Mortality database.

Aims

Fracture of the odontoid process (OP) in the elderly is associated with mortality rates similar to those of hip fracture. The aim of this study was to identify variables that predict mortality in patients with a fracture of the OP, and to assess whether established hip fracture scoring systems such as the Nottingham Hip Fracture Score (NHFS) or Sernbo Score might also be used as predictors of mortality in these patients.

Aims

The aim of this study was to explore the prognostic factors for postoperative neurological recovery and survival in patients with complete paralysis due to neoplastic epidural spinal cord compression.

Aims

During revision procedures for aseptic reasons, there remains a suspicion that failure may have been the result of an undetected subclinical infection. However, there is little evidence available in the literature about unexpected positive results in presumed aseptic revision spine surgery. The aims of our study were to estimate the prevalence of unexpected positive culture using sonication and to evaluate clinical characteristics of these patients.

Aims

The aim of this study was to determine the influence of developmental spinal stenosis (DSS) on the risk of re-operation at an adjacent level.

The widespread use of MRI has revolutionised the diagnostic process for spinal disorders. A typical protocol for spinal MRI includes T1 and T2 weighted sequences in both axial and sagittal planes. While such an imaging protocol is appropriate to detect pathological processes in the vast majority of patients, a number of additional sequences and advanced techniques are emerging. The purpose of the article is to discuss both established techniques that are gaining popularity in the field of spinal imaging and to introduce some of the more novel ‘advanced’ MRI sequences with examples to highlight their potential uses.

The revised Tokuhashi, Tomita and modified Bauer scores are commonly used to make difficult decisions in the management of patients presenting with spinal metastases. A prospective cohort study of 199 consecutive patients presenting with spinal metastases, treated with either surgery and/or radiotherapy, was used to compare the three systems. Cox regression, Nagelkerke’s R² and Harrell’s concordance were used to compare the systems and find their best predictive items. The three systems were equally good in terms of overall prognostic performance. Their most predictive items were used to develop the Oswestry Spinal Risk Index (OSRI), which has a similar concordance, but a larger coefficient of determination than any of these three scores. A bootstrap procedure was used to internally validate this score and determine its prediction optimism.

The OSRI is a simple summation of two elements: primary tumour pathology (PTP) and general condition (GC): OSRI = PTP + (2 – GC).

This simple score can predict life expectancy accurately in patients presenting with spinal metastases. It will be helpful in making difficult clinical decisions without the delay of extensive investigations.
