Background. Clinical guidelines recommend epidural steroid injection (ESI) for severe sciatica but there is uncertainty of effectiveness. The POiSE study aims to identify factors, routinely collected in clinical practice that predict outcome in patients who have ESI. This presentation describes characteristics and early clinical outcomes of POiSE participants. Methods. Prospective cohort study in 19 NHS spinal services in England, inviting patients with sciatica listed for an ESI. Participant baseline characteristics and 6-week follow-up outcomes are presented. Outcomes include pain intensity (0–10 NRS), disability (Oswestry Disability Index 0–100) and global change in symptoms.
Background. Serious traumatic injury is a leading cause of death and disability globally, with the majority of survivors developing chronic pain. Methods. The aims of this study were to describe early predictors of poor long-term outcome for post-trauma pain. We conducted a prospective observational study, recruiting patients admitted to a Major Trauma Centre hospital in England within 14 days of their injuries, and followed them for 12 months. We defined a poor outcome as Chronic Pain Grade ≥ II and measured this at both 6-months and 12-months. A broad range of candidate predictors were used, including surrogates for pain mechanisms, quantitative sensory testing, and psychosocial factors. Univariate models were used to identify the strongest predictors of poor outcome, which were entered into multivariate models.
Background. Embodiment- and distraction-based approaches to immersive virtual reality (IVR) show promise in treating persistent low back pain (PLBP). However, which approach is more effective is unclear. This study aims to evaluate the impact of distraction- and embodiment-based IVR on pain processing and patient-reported outcome measures in PLBP. Method. Individuals with PLBP were randomised to receive eight sessions of either distraction- or embodiment-based IVR over two weeks. Outcome measures were evaluated at baseline and after the eighth session. Pain processing was evaluated using conditioned pain modulation (CPM) and temporal summation (TS).
Lumbar fusion remains the gold standard for the treatment of discogenic back pain. Total disc replacement has fallen out of favor in many institutions. Other motion preservation alternatives, such as nucleus replacement, have had limited success and none are commercially available at this time. Two prospective, nonrandomized multicenter studies of lumbar disc nucleus replacement using the PerQdisc 2.0 nucleus replacement device in patients with lumbar discogenic back pain. Early clinical results are presented. A total of 16 patients from 4 international sites (Germany, Paraguay, Canada and Belgium) were enrolled in the trial between May 2019 and February 2021. Data collection points include baseline and postoperatively at 1, 2, 6, and 12 months. Clinical outcome measures were obtained from the Visual Analog Scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), SF-12V2, Analgesic Score (AS), and radiographic assessments. Prospectively gathered data on patient reported outcomes, neurological outcome, surgical results, radiological analysis, and any adverse events. 16 patients had successful implantation of the device. There have been no expulsions of the device. Early postoperative results are available in 13/16 patients at 6 months and 11/16 patients at 12 months. There have been 4 (25%) revision surgeries 3–12 months post implantation between the two trials. 12 of 13 (92%) patients had Minimal Clinically Important Difference (MCID) in ODI at 6 months and 10 of 11 (91%) at 12 months. Mean decrease in ODI from baseline to 12 months was 44.8. At 12 months 8 (73%) patients are not taking pain medication, 1 (9%) patient is taking a narcotic for pain management. 73% of patients are working without restrictions at 12 months post implant. Early clinical and technical results are encouraging. Long term follow up is essential and is forthcoming. Additional patient recruitment and data points are ongoing.
Background. The aim of the Groningen Spine Center (GSC) is to provide personalized and effective interventions to patients with spine-related disorders. The GSC comprises a multidisciplinary team to triage and treat patients most optimally. Aim. To investigate the patient reported clinical results of the treatments of the GSC during seven years of its existence. Patients and methods. The basis of this study is a natural cohort of all patients admitted to the GSC. Treatments existed of rehabilitation, surgery, anesthesiology, medication, referral to else, advice and self-management, or any combination of the above. Baseline characteristics, pain (Numeric Rating Scale; NRS), disability (Pain Disability Index; PDI) and quality of life (Euroqol 5-D;EQ5D) were obtained at baseline and discharge. Per calendar year, effects will be presented. Descriptive statistics, effect sizes and t-tests were calculated.
Purpose of the study and background. A 2011 Cochrane review concluded that spinal manipulative therapy (SMT) is no better than other interventions for reducing pain and improving function in chronic low back pain (CLBP). Using individual participant data (IPD) from trials has advantages, among others: a more precise estimate of the effect and the potential to identify moderators. Our objective was to assess the effect of SMT in adults with CLBP and to identify relevant moderators. Methods. All trials from the 2011 Cochrane review were included in this IPD. We updated the search (April 2016) IPD from eligible studies was requested. Primary outcomes were pain intensity (VAS/NRS) and back-specific function (RMDQ). Risk of bias was assessed. For the treatment effect, an one-stage approach (mixed model technique, intention-to-treat principle) was used; a second-stage approach was conducted as confirmation. For the moderator analyses, one-stage approach was conducted for 19 variables.
Lower back pain (LBP) is one of the ten leading causes of disease burden globally, producing significant detrimental effects on physical and emotional wellbeing whilst having a substantial economic burden for society. There is an inverse relationship between socio-economic status and pain prevalence. The effectiveness of a locally run ‘Back to Fitness Programme’ (6-week education and exercise programme) in the most deprived local authority area in England was evaluated. Patients at Blackpool Hospitals NHS Trust over a 6-month timeframe were included. Initial data were collected from 49 patients (mean age 53.4 years, 67% female). The amount of final data collected varied per outcome measure due to a range of factors. Participants reported the programme had helped with their understanding of pain (n=16, 100%), ability to move around and function (n=15, 94%), and level of pain (n=14, 88%). Looking at Roland Morris Disability Questionnaire scores (n=17), 88% (n=15) of patients indicated a reduction (n=12, 71%) or no change (n=3, 18%) in perceived disability. The Pain Self Efficacy Questionnaire (n=18) showed that 78% (n=14) of participants perceived an increase in their average level of confidence to move despite pain. There was an overall improvement in understanding of pain reflected by Revised Neurophysiology of Pain Questionnaire scores (n=44): 89% (n=39) improved (n=36, 82%) or did not change (n=3, 7%). Regarding lumbar flexion post-programme (n=17), 77% (n=13) of participants demonstrated an improvement (n=9, 53%) or no change (n=4, 24%).A statement of the purposes of the study and background
A summary of the methods used and the results
Background. Complex interventions, such as exercise for LBP, often have many treatment targets. Matching a primary outcome to the target(s) of exercise interventions may provide greater standardized mean differences (SMDs) than using an unmatched primary outcome. We aimed to explore whether the conclusions of exercise trials for LBP might differ with i) improved matching of outcomes to treatment targets and ii) the use of composite outcome measures. Methods and
Background:. Low back pain (LBP) is the most common symptom encountered by osteopaths in the UK and affects a third of the UK population each year. Guidelines recommend using the biopsychosocial (BPS) model for non-specific LBP but it remains unclear what the BPS model actually is and how it applies in osteopathy. The aim of this study was to define the factors included in a BPS approach for non-specific LBP in a manual therapy using a systematic search and scoping review. Methods:. An online search was performed on seven electronic databases. Guidelines and systematic reviews published after 2004 were included. 10% of the articles randomly selected were analysed by second reviewer to assess consistency of information extraction. Disagreements were discussed between the two reviewers. Mediation from the third author was not required.
Aim. To compare outcomes of revision lumbar discectomy to primary surgery in the same patient cohort. Methods. Prospective outcome data in 36 patients who underwent primary and subsequent revision surgery for lumbar disc herniation between 1995 and 2009. Outcome measures used were Visual Analogue Scores for back (VAB) and leg pain (VAL), the Oswestry Disability Index (ODI) and Low Back Outcome Score (LBO). 5 early recurrences within 3 months were excluded.
Introduction. Iatrogenic spondylolisthesis occurs infrequently after posterior decompression. Posterior surgery is challenging due to altered anatomy and scarring. Anterior lumbar interbody fusion (ALIF) allows indirect decompression, restoration of lordosis and fusion. Material and Methods. Retrospective review of 6 patients (5 female, 1 male, mean age 64±5.8 years) with iatrogenic spondylolisthesis (5 L4/L5; 1 L4/L5) treated with stand-alone ALIF (Synfix, BMP2). Assessment of pelvic incidence, listhesis, pre- and post-operative ODI, VAS, global lumbar lordosis and segmental lordosis as outcome measurements.
To compare outcomes and costs of transforaminal endoscopic surgical discectomy (TES) with those of microdiscectomy (Micro). 48 patients with a primary lumbar disc prolapse were randomly allocated by computer to surgery. Assessments were made of leg and back pain (VAS), Oswestry Disability index (ODI), and SF-36 as primary outcomes. Cost data was collated. 25 TES and 23 Micro patients are reported with similar age, sex, smoking status and affected disc levels (14 v.17 L5/S1). Three months following surgery leg pain scores had decreased by 55 and 65% in the two groups. Patient satisfaction ratings were equal. ODI had decreased 15 points in both groups by 1yr and this improvement was maintained to 2 years (final scores: 7±3 TES v.14±13 Micro - means ±SD; p<0.05). Similar changes were noted in SF36-P. Mean bed stay was lower in the TES group (16 v. 40 hours). Other post-operative costs were similar. There were no immediate complications. One revision was required at 12 months (TES) and one at 18 months (Micro). Two patients presented with a disc prolapse at a different level and side (both TES).
Introduction. Orthopaedic Spinal Rapid Access Service (OSRAS) was developed in our institute to provide a structured pathway for management of urgent spinal pathologies during working hours of Monday to Friday. It was delivered through a published rota by a multi displinary team of Extended Scope Practitioner carrying a bleep and a Spinal Surgeon. Aim. To evaluate the efficacy of OSRAS through a prospective audit.
Surgical management of symptomatic lumbar degenerative disc disease (DDD) currently consists of fusion or implantation of a first generation total disc replacement (TDR). This study is the first to evaluate an elastomeric one-piece TDR in a 50-patient European study. Fifty patients with single-level, symptomatic lumbar DDD at L4-S1 who were unresponsive to at least 6-months of non-operative therapy were enrolled in a clinical trial of a viscoelastic TDR (VTDR) at three European sites. Patients were assessed clinically and radiographically at 6 weeks, 3 and 6 months, and 1 and 2 years. Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) were used to assess clinical outcomes. Twenty-eight males and twenty-two females were enrolled in the study. The average age of patients was 39.7 (23 to 61). The operative level was L4/L5 in 13 patients and L5/S1 in 37 patients. There were no intra-operative complications. Quantitative radiographic assessment indicates that the VTDR restores and maintains a physiologically appropriate disc height and angle, while providing range of motion and translation similar to those provided by the natural disc. Mean ODI scores decreased from 48% pre-operatively to 25% at two years follow up. Mean VAS low back pain scores decreased from 7.1 cm pre-op to 3 cm at two years. Median scores indicate that half of the patient population has ODI scores below 13% and VAS back pain scores below 0.5 cm. Clinically and radiologically, this elastomeric disc is performing satisfactorily, and the causes of clinical failures can be more readily identified.
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.
Introduction. Lumbar spinal pain can be a consequence of discogenic pain. After failure of conservative management, lumbar fusions are popular and considered the gold standard. However, these techniques are associated with significant morbidity. A percutaneous trans-sacral technique may address these for L4/L5 and/or L5/S1 alone spinal fusions. Our unit has adopted this technique and presents our initial experience of 51 patients and preliminary results. Method. Patients with a confirmed clinical and radiological evidence of degenerate intervertebral disc with or without prior surgical intervention were selected. Patients with a history of pelvic surgery/radiotherapy were excluded. Data was collected prospectively using the Global Patient Outcome Scoring System and Oswestry Disability Index (ODI) scores at clinical follow-up.
Background. Phone based Physiotherapy is a topical area of investigation. Salisbury, (2013) states it may be as effective as usual care. It is also suggested that satisfaction is similar, but more specific attitudes have not been investigated. This study aims to retrospectively investigate the attitudes of PD vs usual care patients and to identify any differences in the attitudes of spine pain vs peripheral pain patients. Methods and
Background and purpose. Sleep disturbance is a prevalent symptom in people with chronic low back pain (CLBP >12 weeks), but there is currently no knowledge of the effectiveness of physiotherapy for this problem. This study evaluated the feasibility of a randomised controlled trial (RCT) exploring the effects of physiotherapy on sleep disturbance in CLBP [Current controlled trial ISRCTN 54009836]. Methods. A sample of 60 consenting patients with CLBP [23 M, 37 F; mean (SD) age = 44.93 (13.41) years] were recruited in Beaumont Hospital, Dublin and randomly allocated to one of three groups [supervised exercise class (SEC), walking programme (WP) and usual physiotherapy (UP)] in a concealed manner. The main outcomes were sleep quality, functional disability, pain, and quality of life at baseline, 3 and 6 months.
Purpose of the study. To take a snapshot opinion of General Practitioner understanding of the prevalence, diagnosis and management of coccydynia. Methodology. We designed a simple 5 question survey to administer to our local GPs. The survey was sent to 107 GP practices in Devon whose details were provided by The Devon Access Referral Team. We received 128 electronic replies. We also submitted the survey to 50 GPs who attended a study day at our institution – and ensured they had not already completed the electronic format of the same work. Thus we received 178 replies which we believe to be a highly representative sample of our local GPs opinion.
Purpose. The aim of this study is to assess the safety and efficacy of a remote-operated magnetic growth rod in the treatment of 11 patients with progressive early onset scoliosis (EOS). Introduction. The Growth rod technique (GR) has been a viable treatment option for progressive early onset scoliosis (EOS). However, an increased complication rate has been associated with conventional GR due to frequent surgeries required for lengthening. The safety and efficacy of a remote-operated magnetic growth rod (RO-MGR) has been previously reported in a porcine model. We are reporting the preliminary clinical results of this device which obviates the need for repeated surgeries. Methods. Prospective analysis of early clinical and radiographic data of 11 patients, with EOS, undergoing index RO-MGR treatment and at least 3 distractions. The mean age was 8 years (Range 5-12 years). Four patients had single rod (SR) instrumentation and the remaining 7 had a dual rod (DR) construct. Diagnosis was idiopathic 3, neuromuscular 3, congenital 3, syndromic 1 and neurofibromatosis one. In total, 57 rod distractions were performed. Distractions were performed in the clinic without anesthesia or analgesics. The mean preoperative Cobb angle was 68° (range 46°-108°). The mean preoperative T1-S1 length was 304mm (range 243-361mm).
