Within the intervertebral disc (IVD), nucleus pulposus (NP) cells reside within a unique microenvironment. Factors such as hypoxia, osmolality, pH and the presence of cytokines all dictate the function of NP cells and as such the cells must adapt to their environment to survive. Previously we have identified the expression of aquaporins (AQP) within human IVD tissue. AQPs allow the movement of water across the cell membrane and are important in cellular homeostasis. Here we investigated how AQP gene expression was regulated by the microenvironment of the IVD. Human NP cells were cultured in alginate beads prior to cytokine, osmolality, pH and hypoxia treatments and subsequent RT-qPCR to assess regulation of AQP gene expression.Introduction
Methods
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). 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.Purpose and background
Methods
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. 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.Background and objectives
Methods and results
The biopsychosocial (BPS) model is recommended for managing non-specific low back pain (NSLBP) but the best method for teaching the BPS model is unclear. E-learning is a promising alternative to face-to-face methods. This study was a pilot randomised controlled trial (RCT) with embedded interview study to investigate the feasibility of conducting a main RCT and to explore the impact of an BPS for NSLBP e-learning programme on experienced practitioners' attitudes to back pain. Mixed methods evaluated the impact of an evidence-based e-learning programme on participants' attitudes to back pain. A pilot RCT assessed 45 experienced osteopaths' attitudes before and after the intervention, using the Pain Attitudes and Beliefs Scale (PABS) and the Attitudes to Back Pain Scale (ABS). The qualitative study explored 9 participants' views on the e-learning programme and possible impact on their clinical practice. 91% of participants completed the course and the overall satisfaction was very high. Participants' views on the BPS model ranged between not being structural enough, already done and transformative. The e-learning programme was well accepted. It would be feasible to run a main study using the same recruitment procedures, eligibility criteria, randomisation procedure, consent process, data collection and outcome measures.A statement of the purposes of the study and background
A summary of the methods used and the results
The intervertebral disc (IVD) is a highly hydrated tissue which is reduced during degeneration leading to loss of function. Aquaporins (AQP) are a family of 13 (AQP0-12) transmembrane channel proteins that selectively allow the passage of water and other small molecules in and out of cells and are responsible for maintaining water homeostasis. AQP1, 2, 3 and 5 have been identified in the IVD. Here gene and protein expression of all 13 AQPs was investigated in a large cohort of human IVDs to investigate expression during IVD degeneration. Gene expression of all 13 AQPs was investigated in non-degenerate and degenerate tissue from 102 human NP samples using RT-qPCR. AQPs which were expressed at gene level were further investigated in 30 IVD samples by Immunohistochemistry.Introduction
Methods
Advances in surgical and anesthetic technique have resulted in a reducing length of stay for lumbar decompression, with the first day case procedure published in the literature in 1980. Current evidence suggests day case surgery is associated with improved patient satisfaction, faster recovery, reduced infection rates and financial savings. Following the introduction of a locally agreed day case protocol for lumbar microdiscectomy, we reviewed our 30-day postoperative complication rates. To review postoperative complication rates for patients who underwent day case primary lumbar microdiscectomy.Background
Aims
Patient-rated measures are the gold standard for assessing spine surgery outcomes, but there is no consensus on the appropriate timing of follow-up. Journals often demand a minimum 2-year follow-up, but the indiscriminate application of this principle may not be warranted. We examined the course of change in patient outcomes up to 5 years postoperatively. The data from 3′334 consecutive patients (1′789 women, 1′545 men; aged 61±15 years) undergoing first-time surgery between 1.1.2005 and 31.12.2010 for differing lumbar degenerative disorders were evaluated. The Core Outcome Measures Index (COMI) was completed by 3′124 (94%) patients preoperatively, 3′164 (95%) at 3 months follow-up, 3′153 (95%) at 1 year, 3′112 (93%) at 2 years, and 2′897 (87%) at 5 years. 2′502 (75%) completed COMI at all five timepoints.Background
Methods
Early intervention is advocated to prevent long-term work absence due to musculoskeletal (MSK) pain. The SWAP trial tested whether adding a vocational advice (VA) service to best current care led to fewer days work absence over 4 months. The SWAP trial was a cluster randomised controlled trial in 6 general practices, 3 randomised to best current care (control), 3 randomised to best current care and the VA service (intervention). Patients were ≥18 years, absent from work ≤6 months or struggling at work due to MSK pain. Primary outcome was number of days absent over 4 months. Exploratory subgroup analyses examined whether the effect was larger for patients with spinal pain compared to other MSK pain.Introduction
Methods
PROMs have become an integral assessment tool of clinical effectiveness and patient satisfaction. To date, PROMs for lumbar discectomy are not an NHS requirement, although voluntary collection via the British Spine Registry is encouraged. Despite this, PROMs for day case microdiscectomy is scarcely reported. We present PROMs for day case microdiscectomy at Lancashire Teaching Hospitals.
To review PROMs to quantify leg pain, back pain, EQ5D and ODI scores. Evaluate PROMs data collection compliance.Background
Aims
To identify whether patients were satisfied with the overall educational component of the specialist nurse (CNS)/occupational therapist (OT) led pre-operative assessment clinic in order to identify areas which required improvement. The pre-operative specialist nurse led clinic was set up in 2002. The aim was to provide high quality information to patients undergoing elective spinal surgery in order to manage expectations and optimise post-operative recovery. Initially the clinic was specialist nurse led however, in 2006 occupational therapy input was introduced in order to provide an increased depth of information in regard to function and activities of daily living post operatively. In addition this has allowed assistive equipment to be provided pre-operatively. The format of this clinic has enhanced the patient's journey by facilitating reduced length of stay and more timely discharge. A questionnaire was forwarded to a random sample of two hundred patients who attended for pre-operative assessment in the twelve-month period between April 2014 & March 2015. Sixty questionnaires were returned (30% response rate).Purpose of Study/Background
Methodology
Persistent low back and leg pain is a common and highly disabling musculoskeletal condition. Many patients seek the opinion of a neurosurgeon with a view to surgical intervention. Few data are available which document the experiences of patients at these consultations. To investigate the experiences of patients seeking a neurosurgical opinion for back and leg pain.Background
Aims
Neuropathic pain is a challenging pain syndrome to manage. Low back-related leg pain (LBLP) is clinically diagnosed as either sciatica or referred leg pain and sciatica is often assumed to be neuropathic. Our aim was to describe the prevalence and characteristics of neuropathic pain in LBLP patients. Analysis of cross-sectional data from a prospective, primary care cohort of 609 LBLP patients. Patients completed questionnaires, and received clinical assessment including MRI. Neuropathic characteristics (NC) were measured using the self-report version of the Leeds Assessment of Neuropathic Symptoms and Signs scale (SLANSS; score of ≥12 indicates pain with NC).Purpose of study and background
Methods
Many studies have investigated the kinematics of the lumbar spine and the morphological features of the lumbar discs. However, the segment-dependent immediate changes of the lumbar intervertebral space height during flexion-extension motion are still unclear. This study examined the changes of intervertebral space height during flexion-extension motion of lumbar specimens. First, we validated the accuracy and repeatability of a custom-made mechanical loading equipment set-up. Eight lumbar specimens underwent CT scanning in flexion, neural, and extension positions by using the equipment set-up. The changes in the disc height and distance between adjacent two pedicle screw entry points (DASEP) of the posterior approach at different lumbar levels (L3/4, L4/5 and L5/S1) were examined on three-dimensional lumbar models, which were reconstructed from the CT images.Objectives
Methods
Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors need to be identified. The objective of this study was to identify the pre-operative prognostic factors related to the effect of vertebroplasty on acute pain control using a cohort of surgically and non-surgically managed patients. Patients with single-level acute osteoporotic vertebral compression fracture at thoracolumbar junction (T10 to L2) were followed. If the patients were not satisfied with acute pain reduction after a three-week conservative treatment, vertebroplasty was recommended. Pain assessment was carried out at the time of diagnosis, as well as three, four, six, and 12 weeks after the diagnosis. The effect of vertebroplasty, compared with conservative treatment, on back pain (visual analogue score, VAS) was analysed with the use of analysis-of-covariance models that adjusted for pre-operative VAS scores.Objectives
Patients and Methods
Cement augmentation of pedicle screws could be used to improve screw stability, especially in osteoporotic vertebrae. However, little is known concerning the influence of different screw types and amount of cement applied. Therefore, the aim of this biomechanical A total of 54 osteoporotic human cadaver thoracic and lumbar vertebrae were instrumented with pedicle screws (uncemented, solid cemented or fenestrated cemented) and augmented with high-viscosity PMMA cement (0 mL, 1 mL or 3 mL). The insertion torque and bone mineral density were determined. Radiographs and CT scans were undertaken to evaluate cement distribution and cement leakage. Pull-out testing was performed with a material testing machine to measure failure load and stiffness. The paired Objectives

Pedicle-lengthening osteotomy is a novel surgery for lumbar spinal stenosis (LSS), which achieves substantial enlargement of the spinal canal by expansion of the bilateral pedicle osteotomy sites. Few studies have evaluated the impact of this new surgery on spinal canal volume (SCV) and neural foramen dimension (NFD) in three different types of LSS patients. CT scans were performed on 36 LSS patients (12 central canal stenosis (CCS), 12 lateral recess stenosis (LRS), and 12 foraminal stenosis (FS)) at L4-L5, and on 12 normal (control) subjects. Mimics 14.01 workstation was used to reconstruct 3D models of the L4-L5 vertebrae and discs. SCV and NFD were measured after 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm pedicle-lengthening osteotomies at L4 and/or L5. One-way analysis of variance was used to examine between-group differences.Objectives

We performed a systematic review of the literature to determine the safety and efficacy of bone morphogenetic protein (BMP) compared with bone graft when used specifically for revision spinal fusion surgery secondary to pseudarthrosis. The MEDLINE, EMBASE and Cochrane Library databases were searched using defined search terms. The primary outcome measure was spinal fusion, assessed as success or failure in accordance with radiograph, MRI or CT scan review at 24-month follow-up. The secondary outcome measure was time to fusion.Objectives

Lumbar intraspinal cysts (LICs) are rare incidental MRI findings in back pain. Their space-occupying nature make them plausible factors in both non-specific and radicular back pain. Retrospective cohort study of patients with MRI reports of LICs at our center over 5 years. N=26, 13 male, mean age 66 ± 12 years.Background:

Larger breasted women are at higher risk of wearing ill-fitting breast-support garments. Failure to support breasts during everyday activity can lead to physiological conditions including back and breast pain. This study aimed to identify initial and short-term (4 weeks) biomechanical change and patient reported outcome measures (PROMS) in larger breasted women with non-specific back pain (NSBP) when wearing different breast-support garments. 20 females (Age: 32.1±9.4 years; Bra sizes: 36DD-32K) with NSBP were recruited using modified red flags screening. Participants were tested initially in their usual bra, followed by the professionally-fitted and Optifit bras, in randomised order. Pre/post assessments comprised an established bra-fit assessment, body chart analysis, frequency of wear and pain, continuous-pain intensity (SF-MPQ-2), back stiffness and discomfort, neck disability and thoracic posture in standing using 3D-movement analysis. 100% of Usual and 90% of professionally-fitted bras failed the bra-fit assessment, compared to 5% with the Optifit. Though worn the least on average, a short-term intervention with the Optifit bra resulted in significant reductions in reported thoracic pain, clinically important reductions in neck disability, back pain frequency, continuous-pain intensity, stiffness and discomfort compared to the other bras. The Optifit and professionally-fitted bras significantly reduced reported lumbosacral pain compare to the usual bra. There was no initial change in thoracic posture with the Optifit bra however, significant improvements in flexion-extension posture were seen post-intervention.Background:
Methods & Results:
Following lumbar spine surgery patients with a high BMI appear to have increased post-operative complications including surgical site infections (SSI), urinary complications, increased anaesthetic/operative time and a greater need for post-operative blood transfusion. There is no current evidence, however, analysing the effect of BMI on functional outcome. We aimed to analyse the effect of BMI on functional outcome following lumbar spine surgery.Background:
Purpose:
Inconsistent outcome reporting is a problematic issue in systematic reviews of clinical trials in non-specific LBP (NSLBP). To facilitate statistical pooling and improve reliability of reviews, the development of a core outcome set (COS) is recommended. In 1998, Deyo et al. proposed a standardized set of domains and measurement instruments for LBP clinical research. An international steering committee (ISC) was formed to update 1998 recommendations, and to determine, at first, which outcome domains should be included in a COS for clinical trials in NSLBP. The ISC used the OMERACT framework 2.0 to draw a list of potential core domains. This list was presented in a 3-round Delphi survey, in which researchers, clinicians and patients were invited to participate. Criteria for consensus were established a-Background and purpose:
Methods:
Spondylodiscitis is an uncommon condition with an incidence of 1:100,000 to 1:250,000 in developed countries. Diagnosis and treatment can be delayed resulting in poor outcomes. A high index of suspicion is necessary considering the associated mortality, reported at 2–17%. Establishing a diagnosis can be challenging as features are non-specific and onset may be insidious. While treatment is usually conservative, certain situations require surgery. All patients however require careful assessment and monitoring for complications that may require further intervention. A review of our practice in Wexham Park and Heatherwood Hospital NHS Trust from 2009 to 2013 produced a guideline suggesting the need for blood cultures, imaging with MRI and involvement of the infectious diseases and spinal teams. We re-audited (20 cases) to assess compliance with the guidelines, which were in place to reduce the delay in diagnosis. Recurrent presentation, infections of unknown origin and deterioration after a short course of antibiotics were indicators for triggering imaging of the spine for discitis. Delays in diagnosis were more marked in bacterial cases rather than tuberculosis. It was impossible to predetermine patients that would require surgical intervention. Our compliance with the guideline had improved from 70 to over 90% and there were no relapses or mortality.
The use of Patient Reported Outcome Measures (PROMs) to measure effectiveness of care, and supporting patient management is being advocated increasingly. PROMs data are often collected using hard copy questionnaires. New technology enables electronic PROM data collection. To identify patient and practitioner perceived opportunities and challenges to implementing electronic PROM data capture as part of the process for developing a PROM phone and online app.Background to the study:
Purpose of the study:
Chronic back pain is a complex and poorly understood condition incorporating sensory, cognitive and emotional elements. Research demonstrates a strong association between chronic back pain and cognitive and non-cognitive factors such as anxiety, depression, fear-avoidance and self-efficacy. However, until very recently, the way in which chronic back pain sufferers process their emotions was largely unknown. To this end, we conducted two case-control studies using a between-groups correlational design to investigate the relationship between chronic back pain and emotional processing. In study 1, 55 chronic back pain sufferers and 55 pain-free individuals were administered the Emotional Processing Scale (EPS) to determine whether chronic back pain sufferers process their emotions differently from pain-free individuals. In study 2, 32 CBP sufferers and 27 pain-free individuals were administered the EPS, PHQ-9 and the GAD-7 to further test if chronic back pain is associated with altered emotional process and whether anxiety and depression may play a role in this relationship.Background and purpose of study:
Methods and results:
Low back pain (LBP) is the leading cause of disability worldwide, and greater understanding of mechanisms leading to increased disability in LBP is necessary. Pain-related guilt and in particular social guilt (one type of pain-related guilt) has recently been linked to greater depression, anxiety and disability in LBP. Research has also shown that greater acceptance of pain is associated with less pain intensity, depression, pain-related anxiety and disability, and with greater daily activity and overall wellbeing in chronic pain patients. The current study aim was to understand the relationship between pain-related guilt and pain-related acceptance in LBP. The study examined the relationship between pain-related guilt and pain-related acceptance in a sample of 287 LBP patients. A series of hierarchical multiple regression analyses were conducted in which known correlates of pain-related acceptance (pain intensity, disability, depression and anxiety) were controlled for, with the objective of testing whether pain-related guilt explains any unique variance in pain-related acceptance. Social guilt was the strongest predictor of reduced pain-related acceptance in all analyses.Statement of the purposes of the study and background:
Summary of the methods used and the results:
To identify treatment effect modifiers within the STarT Back Trial which demonstrated prognostic stratified care was effective in comparison to standard care for patients with low back pain. Secondary analysis of the STarT Back Trial using 688 patients with available 4-month follow-up data. Disability (baseline and 4 months) was assessed using the Roland Morris Disability Questionnaire (RMDQ) using continuous and dichotomized (>7) outcome scores. Potential treatment effect modifiers were evaluated with group x predictor interaction terms using linear and logistic regression models. Modifiers included: age, gender, education, socio-economic status (SES), employment status, work satisfaction, episode duration, general health (SF-12), number of pain medications, and treatment expectations.Purpose and Background:
Methods:
Low Back Pain and Neck Pain rank 1 and 4 on the causes of years lost to disability (YLDs) in the UK. Treatment options are broad including popular approaches such as chiropractic care but with NHS funding limited to recent initiatives such as Any Qualified Provider (AQP). Eleven chiropractic practices with AQP contracts took part in the study. As part of routine clinical practice, patients are entered onto a web based patient reported outcome system that sends automated e mails links to questionnaires, prior to the initial visit (includes the Bournemouth Questionnaire (BQ) and STarT Back, and at 14, 30 and 90 days (BQ and Patient Global Impression of Change (PGIC)). Data from subjects consenting for such use were used in the analysis.Background:
Method:
To employ a simple and fast method to evaluate those patients with neurological deficits and misplaced screws in relatively safe lumbosacral spine, and to determine if it is necessary to undertake revision surgery. A total of 316 patients were treated by fixation of lumbar and lumbosacral transpedicle screws at our institution from January 2011 to December 2012. We designed the criteria for post-operative revision scores of pedicle screw malpositioning (PRSPSM) in the lumbosacral canal. We recommend the revision of the misplaced pedicle screw in patients with PRSPSM = 5′ as early as possible. However, patients with PRSPSM < 5′ need to follow the next consecutive assessment procedures. A total of 15 patients were included according to at least three-stage follow-up.Objectives
Methods
A distinction has been posited between cognitive (informational) and affective (emotional) reassurance, with a suggestion that affective reassurance may negatively affect patient outcomes by reducing patients' motivation to engage with information conducive to recovery. Cognitive reassurance, though, provides explanations and information to help patients self-manage, and so aids recovery. However, research is lacking on how each actually affects patient outcomes in primary care. To develop a valid measure of practitioner reassurance, and assess the impact of different reassurance strategies on patients' outcomes.Background:
Purpose of the Study:
Internet interventions provide an opportunity to encourage patients with LBP to self-manage and remain active, by tailoring advice and providing evidence-based support for increasing physical activity. This paper reports the development of the ‘SupportBack’ internet intervention, designed for use with usual primary care, as the first stage of a feasibility RCT currently underway comparing: usual primary care alone; usual care plus the internet intervention; usual care plus the internet intervention with physiotherapist telephone support. The internet intervention delivers a 6-week, tailored programme focused on graded goal setting, self-monitoring, and provision of tailored feedback to encourage physical activity/exercise increases or maintenance. 22 patients with back pain from primary care took part in ‘think aloud’ interviews, to qualitatively explore the intervention, provide feedback on its relevance and quality and identify any extraneous content or omissions.Background:
Methods:
Clinical interpretations of Degenerative Lumbar Disc Disease are not described in the literature. The purpose of this study was to establish a consensus of expert clinical opinion in order to fuel further research. A reliable and valid electronic survey was designed to include theoretical constructs relating to training and education, general knowledge, assessment and management practices. Clinicians from the Society of Back Pain Research U.K. were invited to take part. Quantitative data was collated and coded using Bristol on-line survey software, and content analysis was used to systematically code and categorize qualitative data.Purpose and Background:
Methods:
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. 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.Background:
Methods:
We have recently shown, using transcranial magnetic stimulation (TMS) to assess voluntary activation (VA), that neural drive to back muscles is reduced in subjects with chronic low back pain. There is also evidence that central nervous system drive to abdominal muscles is altered in these subjects, however VA has not yet been assessed for these muscles in healthy subjects; this is the purpose of the present study. Twenty one healthy subjects (10M:11F) participated. Electromyographic activity was recorded from back and abdominal muscles and flexor torque was measured using a dynamometer. Subjects performed a series of isometric voluntary contractions (10%–100% MVC) of rectus abdominis during which TMS was applied to the motor cortex. The resulting superimposed twitches (SIT) were measured and VA was derived.Background:
Methods:
Outcome after traumatic spinal fracture is difficult to predict. Some patients have ongoing pain while others make a good recovery and there is therefore considerable debate as to which fractures should be treated operatively. Delayed operations for ongoing pain post fracture are more expensive with a longer recovery. The sagittal balance of the spine may predict patient outcomes post fracture. Identify subjects with stable spine fractures not requiring acute fixation and compare their sagittal parameters measured on initial standing x-ray with whether or not they have ongoing pain.Background:
Aim:
Merely publishing clinical guidelines is insufficient to ensure their implementation in clinical practice. We aimed to clarify the decision-making processes that result in the delivery of particular treatments to patients with low back pain (LBP) in primary care and to examine clinicians' perspectives on the National Institute for Health and Care Excellence (NICE) clinical guidelines for managing LBP in primary care. We conducted semi-structured interviews with 53 purposively-sampled clinicians from south-west England. Participants were: 16 General Practitioners (GPs), 10 chiropractors, 8 acupuncturists, 8 physiotherapists, 7 osteopaths, and 4 nurses. Thematic analysis showed that official guidelines comprised just one of many inputs to clinical decision-making. Clinicians drew on personal experience and inter-professional networks and were constrained by organisational factors when deciding which treatment to prescribe, refer for, or deliver to an individual patient with LBP. Some found the guideline terminology - “non-specific LBP” - unfamiliar and of limited relevance to practice. They were frustrated by disparities between recommendations in the guidelines and the real-world situation of short consultation times, difficult-to-access specialist services and sparse commissioning of guideline-recommended treatments.A statement of the purposes of the study and background:

To explore clinicians' perceptions of empathy during musculoskeletal clinical consultations. Empathy is considered essential to creating a positive experience within healthcare for both the patient and clinician, improving adherence, creating trust and improving patient experience. However, little is known about how clinicians acquire and display empathic communication skills during musculoskeletal consultations.Purpose:
Background:
Cauda Equina Syndrome (CES) is a rare condition which, even in the presence of prompt surgical decompression, can have devastating consequences for patients in terms of bladder and bowel dysfunction. The aim of this project was to develop a post-operative pathway for the assessment and management of bladder and bowel dysfunction in patients with CES. Beaumont Hospital performs a high volume of spinal surgeries. A small number are lumbar decompression surgeries due to CES. While sphincter function is routinely screened by a physiotherapist post-operatively, to date there has been no protocol in place for assessment and management of bladder and bowel dysfunction in this population. This project was carried out in collaboration with consultants in urology and colorectal surgery, as well as clinical nurse specialists in both areas.Purpose and background:
Method:
Despite the rise of back pain disability, objective mechanical assessment is generally lacking. Quantification of intervertebral kinematics using fluoroscopy provides objective measurement, but its use in clinical practice has not been assessed. This study reviewed cases referred to one UK site for lumbar spine quantitative fluoroscopic (QF) examinations and compared the reasons for referral with the findings reported. Fifty-seven consecutive referrals were reviewed. Patients underwent passive recumbent and/or weight-bearing active examinations in either the sagittal or both the sagittal and coronal planes. Data were extracted from anonymised QF reports and analysed for patient characteristics, reason for referral, working diagnosis at referral, level(s) of interest, previous surgical procedures and findings reported. Reports were also thematically analysed for key findings. Most patients had chronic back conditions of moderate or severe intensity. Most (38/57) were male, mean age 47 (SD 13.1) and mean complaint duration 5.4 years (0.3–32 years). They were referred mainly to investigate segmental instability (19/54) or spondylolisthesis (13/54) to inform either surgical referral or conservative management. Instability was reported in only 8/57 cases, but restricted and hypermobile levels in the same patient was also common (13/57). In 11 cases no mechanical abnormality was found.Purpose and Background:

Method:
The inability of intervertebral joints to resist perturbation due to laxity is traditionally measured in cadaveric specimens as their neutral zones (NZ). However in patients, quantitative fluoroscopic (QF) examinations substitute the Initial Attainment Rate for this. If these two measures correspond sufficiently, a clinical method for measuring segmental instability is possible. This study explored this by determining the criterion validity of the Initial Attainment Rate against the Dynamic NZ in an unloaded multilevel porcine spine. A 5-segment porcine spine was prepared and mounted on a motorised horizontal motion platform fitted with a digital force gage. Left and right bending moments were calculated about each intervertebral joint for 10 repeated side bends using an inverse dynamics method. The Dynamic NZs and Initial Attainment Rates in the first 10° of platform motion at each level were correlated. The Initial Attainment Rates were comparable to those found Background and Purpose:
Methods and Results:
The aim of this study is to evaluate the long-term outcome after posterior spinal stabilization surgery for the management of de novo non-tuberculous bacterial spinal infection. Patients presenting to a single tertiary referral spinal centre between August 2011 and June 2014 were included in the study. 21 patients with nontuberculous bacterial infection were identified and included in the study. All patients were managed surgically with posterior stabilisation, with or without neural decompression, without debridement of the infected tissue. Neurological state was assessed using the frankel grading system before and after urgery. Long-term follow-up data was collected using SpineTango COMI questionnaires and Euro Qol EQ-5D system with a mean follow-up duration of 20 months postoperatively. The mean improvement in neurological deficits was 0.92 Frankel grade (range 0–4). At final followup, at a mean of 20 months, mean COMI score was 4.59, average VAS for back pain was 4.28. These symptoms were having no effect or only minor effect on the work or usual activities in 52%. 38% of patients reported a good quality of life. The average EQ-5D value was 0.569. There were no problems with mobility in 44% of patients. In 72% there were no problems with self-care.Back ground:
Method and Result:
T2D is postulated to be an important aetiological factor for lumbar disc degeneration (LDD), which itself has a well documented relationship with low back pain. Obesity increases risk of both T2D, low back pain and LDD. Connective tissue modification has been reported in hyperglycaemia, but the epidemiology of LDD in T2D has not been described to date. A population sample of unselected same-sex adult twin pairs was studied who had attended a spine MR study and completed general health questionnaires defining T2D by self-report. LDD had been coded as the sum of five lumbar discs coded (0–3) for each of height, signal intensity, disc bulge and anterior osteophytes. Risk factors for LDD included age, body-mass index (BMI), sex, alcohol consumption and smoking. Mean age of the 1011 participants = 54 years (sd=8), mean BMI=25 kg/m2 (sd=4), 95% female. The prevalence of T2D was 6%. Twins with T2D had increased BMI (27 vs 25 kg/m2, p<0.001) and were older (59 vs 54 years, p<0.001). LDD score in T2D was significantly higher in diabetic cases than controls (14.9 vs 13.1, p=0.04) in univariable analysis. In multivariable analysis inclusion of age and BMI abrogated the effect of T2D.Background and aims:

The spread of upright MRi scanning is a relatively new development in the UK. However, there is a lack of information about whether weight bearing scans confer any additional useful information for low back conditions. Forty-five patient referrals to the upright MRI Department at the AECC for weight bearing lumbar spine scans between November 1st 2014 and June 30th 2015, and the resulting radiologists' reports were reviewed. Age, gender, clinical history, summary of findings, type of weight bearing scanning performed (sitting, standing, flexion, extension) were abstracted. All patients were scanned in a 0.5T Paramed MRopen scanner and all also received supine lumbar spine sagittal and axial scans. The patients comprised 18 females and 27 males, mean age 52 years, (SD 15.5). Thirty had leg pain, 6 of which was bilateral. In 15, a stenotic lesion was suspected. Other reasons for referral were; possible malignancy (1), effects of degenerative change (4), spondylolisthesis (2), fracture, (1), previous surgery (3), trauma (1), sacroiliitis (1) and instability (3). In 12/45 cases, reportable findings were more prominent, and sometimes only identifiable, on weight bearing scans, while in a further 4, the reverse was true. All but one of these involved disruption of the spinal or root canals. Eight of them also involved positional alignment.Purpose and Background:
Methods and Results:
To evaluate if adding clonidine to a standard nerve root block containing local anaesthetic and steroid improved the outcome of patients with severe lumbar nerve root pain secondary to MRI proven lumbar disc prolapse. We undertook a single blind, prospective, randomised controlled trial evaluating 100 consecutive patients with nerve root pain secondary to lumbar disc prolapse undergoing trans-foraminal epidural steroid injection either with or without the addition of clonidine. 50 patients were allocated to each arm of the study. The primary outcome measure was the avoidance of a second procedure- repeat injection or micro-discectomy surgery. Secondary outcome measures were also studied: pain scores for leg and back pain using a visual analogue scale (VAS), the Roland Morris Disability Questionnaire (RMDQ) and the Measure Your Own Medical Outcome Profile (MYMOP). Follow up was carried out at 6 weeks, 6 months and 1 year.Purpose:
Methods:
The use of Patient Reported Outcome Measures (PROMs) is being increasingly advocated but data are still being collected using paper systems. This is costly and environmentally challenging. New innovations are required to balance the challenges of capturing PROM data while considering budgets, and access to IT, and patient choice. To develop and test a mobile phone and web app for collecting patient reported outcomes about musculoskeletal symptoms.Background to the study:
Purpose of the study:
To produce objective evidence that lifting is more comfortable in lumbar flexion than lumbar extension. Traditionally, lifting is taught in lumbar extension (“straight back”) but in our experience is more comfortable and stronger in flexion with backward lumbar tilt. 58 subjects performed maximal comfortable static lifts: ‘Natural’ lifting position - hip flexion, knee extension, lumbar extension Traditionally taught position - hip flexion, knee flexion, lumbar extension Backward pelvic tilt - hip flexion, knee flexion, lumbar flexion The order of these lifting methods varied to allow for variation due to fatigue/recruitment. All lifts were measured with a computerised dynamometer. The mean force for natural lifting was 13.4 kgs, for traditionally taught lifting 15.1 kgs and for backward pelvic tilt lifting 22.2 kgs This represented a 13% greater load for traditionally taught lift compared with natural lift, 66% greater for backward pelvic tilt compared with natural lift and 48% greater for backward pelvic tilt compared with traditionally taught lift.Purpose:
Method and results:
Modic change (MC) describes vertebral endplate and bone marrow lesions visible on MRI. MC has been associated with disc degeneration (DD). Independent association of MC with low back pain (LBP) is unclear. The objectives of this study were to assess the relationship between MC and severe, disabling LBP; prevalence and features of DD and incident MC during 10-year follow-up. Unselected TwinsUK volunteers were recruited to MRI and nurse interview in 1996–2000 (n=823): a subset attended for follow-up a decade later (n=429). T2-weighted lumbar MR scans were coded blindly for MC, DD (loss of disc height and signal intensity, disc bulge and anterior osteophytes) and Schmorl's nodes (SN). Mean baseline age = 54.0 (32–70) years with 96% female. Prevalence of MC was 32.2% (baseline) and 48.7% (follow-up). Univariable analyses showed subjects having MC were older (p<0.001) and more overweight (p=0.026). At both timepoints subjects reporting severe LBP episodes demonstrated more MC (both p<0.001) than those without LBP. In multivariable analyses, MC remained significantly associated with episodes of severe, disabling LBP (OR 1.58; 95% CI 1.04–2.41) even after adjustment for age, BMI, DD and SN. Loss of disc height and disc signal intensity were independently associated with prevalent MC at baseline, and disc height and disc bulge with incident MC during follow-up.Background and purpose of study:
Methods and results:
MRI findings associated with spondyloarthritis (SpA) can be difficult to distinguish from the more prevalent findings of degeneration. Despite this, the two groups of MRI-findings are often evaluated in separate studies and in different study populations, which may reduce their applicability in daily clinical practice. The purpose of this study was to estimate the prevalence of degenerative and SpA related MRI-findings in the spine and sacroiliac joints (SIJ) in patients with persistent LBP. Patients with persistent LBP (n=1037, median age 33 [IQR 27–37], 54% women) referred to an outpatient, secondary care and non-surgical department were included in the study. MRI of the whole spine and the SIJ was performed and degenerative and SpA-related MRI-findings were evaluated by experienced musculoskeletal radiologists.Purpose and background:
Methods:
Sacroiliitis identified by MRI is considered as a keystone in the diagnosis of spondyloarthritis. To reduce the number of unnecessary MRI scans it would be ideal if sacroiliac (SI) joint pain provocation tests could be used to identify patients at risk of having sacroiliitis. The aim of the current study was to investigate the diagnostic value of three pain provocation SI-joint tests for sacroiliitis identified by MRI. Patients (n=454, mean age 32 years, 54% women) without clinical signs of nerve root compression were selected from a cohort consisting of patients with persistent low back pain referred to an outpatient spine clinic. Data from the Gaenslen's Test, Thigh Thrust Test and Long Dorsal Sacroiliac Ligaments Test and sacroiliitis identified by MRI were analysed.Purpose and background:
Methods:
Previous studies have stated that presence of concomitant back pain has a negative effect on the outcome of lumbar decompression/microdiscectomy but none have actually defined what level of back pain should be considered as significant. This is a study of consecutive patients who underwent a primary single level lumbar micro decompression /microdiscectomy performed by thirty nine surgeons at a single tertiary spinal centre between August 2011 and December 2014. The aim was to determine the differential effect of the intensity of back pain and leg pain as a predictor of outcome. Data was prospectively collected using SpineTango COMI questionnaires pre-operatively and at 3 months postoperatively. 995 patients who had a complete dataset were included in the analysis. Multivariate regression analysis and ROC curves were used to evaluate factors associated with poor outcome. At 3 months follow up 72.16% of patients were satisfied with the outcome of surgery. The VAS for low back pain was a significant predictor of poor outcome. Of patients with a VAS of 6 or more 34% had a poor outcome following surgery while of patients with a VAS of less than 6, 17% had a poor outcome at three months.Back ground:
Method and Result:
To compare static and dynamic lumbar intervertebral ranges of motion (IV-RoM) in patients with chronic, nonspecific low back pain with upper and lower cut off values derived from healthy controls when variability and measurement errors were reduced. Measurements from functional radiographs suffer from high variability and measurement errors, making cut off values for excessive or insufficient motion problematical. This study compared maximum lumbar IV-RoM and maximum IV-RoM at any point in continuous motion sequences in patients with chronic, non-specific back pain with upper and lower cut off values for L2 to L5 from matched controls using quantitative fluoroscopy, where variation and measurement errors were reduced. Participants underwent passive recumbent examinations in the sagittal and coronal planes. Values based on were developed for both maximum and continuous motion in controls (n=40). Fishers exact test was used to analyse proportions of patients whose IV-RoMs exceeded reference values. For maximum IV-RoM in patients, there were no statistically significant differences between groups for the lower value. Only flexion at L4/5 significantly exceeded the upper value (p=0.03). For continuous IV-RoM, left L3/4 (p=0.01) and right L4/5 (p=0.01) were significantly below the lower cut off values. Both flexion L4/5 (p=0.05) and left L3/4 (p=0.01) were significantly above the upper cut off values.Purpose and Background:
Methods and Results:
Several reports showed superior fusion rates, as high as 100%, using rhBMP-2 with ALIF cages. This has led to the widespread off-label use of rhBMP-2 in several other lumbar fusion procedures. There is paucity of reports analysing the clinic-radiological outcome of using rhBMP-2 to promote bone union in cases of symptomatic pseudoarthosis following lumbar spine fusion. 52 consecutive patients who underwent revision spinal surgery for symptomatic pseudoarthosis utilizing rhBMP-2 between 2008 and 2013 were included in the study. Demographic, and surgical data were collected from medical records. Functional outcomes were recorded using the ODI. All patients had preoperative fine-cut CT scan to confirm pseudoarthosis. Postoperative CT-scan at 6 months was routinely done to confirm fusion.Introduction:
Methods:
To establish the demand, referral pathways, utility and patient satisfaction of a physiotherapy led post operative spinal surgery review clinic. 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.Objectives:
Methods:
Implementation fidelity (IF) is the extent to which an intervention is implemented as intended by its developers, and increases confidence that changes in study outcomes are due to the effect of the intervention itself and not due to variability in implementation. The aim of this study was to evaluate the IF within a behaviour-change self-management intervention for people with chronic low back pain and/or osteoarthritis, consisting of six weekly sessions (SOLAS ISRCTN49875385). In a sample of data, the intervention was delivered by physiotherapists (n=9) in seven sites. IF was assessed using self-report (by physiotherapists) of all sessions (n=60), direct observations (by the research team) of 40% of the sessions (n=24) and audio-recorded observations (by the research team) of all sessions (n=60) using checklists. Data were analysed in SPSSv20 to assess % agreement between methods and fidelity scores.Purpose and background:
Methods:
Identification of nerve root involvement (NRI) in patients with low back-related leg pain (LBLP) can be challenging. Diagnostic models have mainly been developed in secondary care with conflicting reference standards and predictor selection. This study aims to ascertain which cluster of items from clinical assessment best identify NRI in primary care consulters with LBLP Cross-sectional data on 395 LBLP consulters were analysed. Potential NRI indicators were seven clinical assessment items. Two definitions of NRI formed the reference standards: (i) high confidence (≥80%) NRI clinical diagnosis (ii) high confidence (≥80%) NRI clinical diagnosis with confirmatory magnetic resonance imaging (MRI) findings. Multivariable logistic regression models were constructed and compared for both reference standards. Model performances were summarised using the Hosmer-Lemeshow statistic and area under the curve (AUC). Bootstrapping assessed internal validity.Background:
Methods:
Combined physical and psychological (CPP) programmes are widely recommended for Chronic Low Back Pain (CLBP) patients. Patients with longstanding CLBP participating in a two-week CPP-programme improve in functional status and quality of life and the results are maintained for at least one year. First indications of maintenance of improved patient-reported outcomes are shown at two-year follow-up assessment. Evaluation of the long-term (at least five years of follow up) maintenance of positive results of a short, intensive, evidence based CPP-programme.Background:
Purpose:
Many operations have been recommended to treat Pars Interarticularis fractures that have separated and are persistently symptomatic, but little other than conservative treatment has been recommended for symptomatic incomplete fractures. 10 consecutive patients aged 15–28 [mean 21.7 years] were treated operatively between 2010–2014. All but one were either professional athletes [3 cricketers, 2 athletics, 1 soccer] or academy cricketers [3 patients]. 8 patients had unilateral fractures, and two had bilateral fractures at the same level. The duration of pre-operative pain and disability with exercise ranged from 4–24 months [mean 15.4 months]. The operation consists of a percutaneous compression screw inserted through a 1.5cm midline skin incision under fluoroscopic guidance: 6 cases were also checked with the O-arm intra-operatively. Post-operation the patients were mobilised with a simple corset and discharged the following day with a customised rehabilitation program. All 12 fractures in 10 patients healed as demonstrated on post-operative CT scans at between 3–6 months. One patient had the screw revised at 24 hours for an asymptomatic breach, and one patient developed a halo around the fracture site without screw loosening, and had a successful revision operation to remove the screw and graft the pars from the screw channel. All patients achieved a full return to asymptomatic activity, within a timescale of 4–12 months post-surgery, depending on the sport. Athletes that have persistent symptoms from incomplete pars interarticularis fractures should consider percutaneous fixation rather than undergoing prolonged or repeated periods of rest.
There is no universally agreed definition of
cauda equina syndrome (CES). Clinical signs of CES including direct
rectal examination (DRE) do not reliably correlate with cauda equina (CE)
compression on MRI. Clinical assessment only becomes reliable if
there are symptoms/signs of late, often irreversible, CES. The only
reliable way of including or excluding CES is to perform MRI on
all patients with suspected CES. If the diagnosis is being considered,
MRI should ideally be performed locally in the District General
Hospitals within one hour of the question being raised irrespective
of the hour or the day. Patients with symptoms and signs of CES
and MRI confirmed CE compression should be referred to the local
spinal service for emergency surgery. CES can be subdivided by the degree of neurological deficit (bilateral
radiculopathy, incomplete CES or CES with retention of urine) and
also by time to surgical treatment (12, 24, 48 or 72 hour). There
is increasing understanding that damage to the cauda equina nerve roots
occurs in a continuous and progressive fashion which implies that
there are no safe time or deficit thresholds. Neurological deterioration
can occur rapidly and is often associated with longterm poor outcomes.
It is not possible to predict which patients with a large central
disc prolapse compressing the CE nerve roots are going to deteriorate neurologically
nor how rapidly. Consensus guidelines from the Society of British Neurological
Surgeons and British Association of Spinal Surgeons recommend decompressive
surgery as soon as practically possible which for many patients
will be urgent/emergency surgery at any hour of the day or night. Cite this article:
Stratifying patients with Low Back Pain (LBP) using the STarT Back Tool and delivering targeted treatment has demonstrated efficacy in individual physiotherapy settings. Physiotherapy interventions for LBP patients are often delivered in groups. This study aimed to explore the sustainability and cost effectiveness of a group stratified intervention in primary care. This non-randomised controlled trial compared a novel group stratified intervention to a historical non-stratified group control. Patients from 30 GP practices in Waterford Primary Care were stratified and offered a matched targeted group intervention. The historical control received a generic group intervention. The primary outcome measure was disability (RMDQ) at 12 weeks. A cost effectiveness analysis was also undertaken. Analysis was by intention to treat. Ethical approval was obtainedBackground
Methods
To explore the cost-utility of implementing stratified care for low back pain (LBP) in general practice, compared with usual care, within patient risk subgroups (low, medium and high risk of persistent disabling pain determined by the STarT Back tool). Adopting a cost-utility framework alongside a prospective, sequential comparison of separate patient cohorts (922 patients in total) with six-month follow-up, the base case analysis estimated the incremental LBP-related healthcare cost per additional quality-adjusted life year (QALY) by risk subgroup. Uncertainty was explored with cost-utility planes and acceptability curves. Sensitivity analyses examined alternative approaches (a complete case analysis, the incorporation of non-LBP-related healthcare use and estimation of societal costs relating to work absence).Purpose and background
Methods
Medical Research Council (MRC) guidelines recommend applying theory within interventions to explain how behaviour change occurs. Guidelines endorse self-management of chronic low back pain (CLBP) and osteoarthritis (OA), but evidence for its effectiveness is weak. This literature review aimed to determine the use of behaviour change theory and techniques within group-based self-management randomised controlled trials for chronic musculoskeletal pain, including CLBP and OA. A two phase search strategy of electronic databases was used to identify systematic reviews and studies relevant to this area. Articles were coded independently for their use of behaviour change theory, and the number of behaviour change techniques (BCTs) was identified using a 93 item taxonomy, Taxonomy (v1).Background
Methods
Research has suggested baby wearing results in happier healthier babies [1]. Various designs of carrier are available, is there one which has less impact on the biomechanics of the cervical spine? 18 volunteers (9 male and female) performed a warm up procedure on the neck (movement through each range of motion), repeated thrice. Measurement of the active cervical range of motion (ACROM) in flexion and extension using a Cervical Range of Motion device, described in previous studies [2]. Volunteers were then allocated a baby carrier to wear including a specially designed “baby” mannequin (dimensions based on population average statistics for a 1yro). Volunteers continued with ADLs, returning after 2 hours. With the carrier removed, measurements were repeated (without warm-up). Volunteers were assessed at the same time of day, thrice (control, single carrier, double carrier) with at least 1 day between carrying.Introduction
Methods
Over two-thirds of pregnant women experience low back pain (LBP) that interferes with everyday activities, work and sleep. Acupuncture appears a safe, promising intervention but there are no high quality trial data, regarding its clinical or cost-effectiveness in comparison to standard care. EASE Back was a feasibility and pilot RCT designed to inform a full trial evaluating the addition of acupuncture to standard care for pregnancy-related LBP. In preparation for the pilot trial, phase 1 of EASE Back consisted of semi-structured interviews exploring the views of pregnant women, midwives and physiotherapists about pregnancy-related LBP, use of acupuncture, and participation in clinical trials. Transcript data were anonymised and analysed using thematic analysis. Three members of the team independently coded a sample of transcripts to develop the coding framework.Purpose and background
Methods
Emerging research has indicated that ‘significant others’ (spouses/relatives) may have important influences on continued work participation for individuals with chronic non-specific musculoskeletal pain (CMP). In order to expand on this novel area of research, data from studies conducted in The Netherlands and the UK were assimilated. In both studies, worker and significant other perceptions of pain self-efficacy, perceived partner responses to pain, pain catastrophizing, and contribution to work participation were explored in relation to the worker's CMP. In the Netherlands, questionnaire data were collected from workers with CMP and their significant others (n=103), and in the UK, in-depth semi-structured interviews were conducted (n=10). Appropriate quantitative and qualitative analysis techniques were applied.Background
Method
Patients' beliefs about the origin of their pain and their cognitive processing of pain-related information have both been shown to be associated with poorer prognosis in low back pain (LBP), but the relationship between specific beliefs and specific cognitive processes is not known. The aim of this study was to study the relationship between diagnostic uncertainty and recall bias in two groups of chronic LBP patients, those who were certain about their diagnosis, and those who believed that their pain was due to an undiagnosed problem. Patients (N=68) endorsed and subsequently recalled pain, illness, depression and neutral stimuli. They also provided measures of pain, diagnostic status, mood and disability. Both groups exhibited a recall bias for pain stimuli, but only the group with diagnostic uncertainty additionally displayed a recall bias for illness-related stimuli. This bias remained after controlling for depression and disability. Sensitivity analyses using grouping by diagnosis/explanation received supported these findings. Higher levels of depression and disability were found in the group with diagnostic uncertainty, but levels of pain intensity did not differ between the groups.Purpose of the study and background
Summary of the methods used and the results
Spinal stability is associated with low back pain and affects the spines ability to support loads. Stability can be achieved if the applied force follows the curvature of the spine, passing close to the vertebral centroids. Previously we showed that calculated muscle forces required for stability in an idealised model increased with increasing and more evenly distributed lumbar curvatures. The purpose of this study was to calculate the muscle forces required for stability in standing in a group of healthy adults. Positional MRI was used to acquire sagittal images of the lumbar spine in a standing posture in 30 healthy adults. Sacral inclination was measured and active shape modelling used to characterise lumbar spine shape. A two-dimensional model of the lumbar spine was constructed using vertebral centroid positions and a simplified representation of the lumbar extensor muscles. The muscle forces required at each level to produce a follower load were calculated using a force polygon.Background and Aim
Methods
Characteristics of muscle activity, represented by surface electromyography (EMG), have shown differences between patients with low back pain and healthy adults; how they relate to functional/clinical scales remains unclear. The purpose of the current study was to examine the correlation between frequency characteristics of EMG and patients' self-rated score of disability using continuous wavelet transform (CWT) analysis. Fifteen patients with chronic mechanical low back pain (LBP) and 10 healthy adults were recruited. Patients completed the Roland-Morris Disability Questionnaire (RMDQ) and bilateral EMG activity was obtained from erector spinae at vertebral level L4 and T12. Subjects performed 3 brief maximal voluntary contractions (MVCs) of the back extensors and the torque was measured using a dynamometer. CWT was applied to the EMG signals of each muscle in a 200ms window centred around the peak torque obtained during the MVCs. The ratio (low/high frequencies) of the energy, the peak energy, and the frequency of the peak energy were calculated for each muscle and then averaged and correlated with the individual's RMDQ score. Patients had significantly lower peak power than the controls (p=0.04). Additionally, RMDQ positively correlated to the average ratio of energy (rho=0.71; p=0.01), meaning higher disability corresponded to a dominant distribution of energy in the lower-frequencies; but negatively correlated to the average frequency of peak energy (rho=-0.61; p=0.035), meaning lower frequency of peak energy corresponded to higher levels of disability.Purposes of the study and background
Methods and Results
The use of NRB (Nerve Root Block) in radicular pain caused by stenosis is considered controversial in some centres, whereas its indication in radiculitis caused by disc herniation is widely accepted. Most studies evaluating NRB have combined disc herniation and stenosis pathologies in their inclusion criteria. This study explores the efficacy of NRB in different categories of stenosis: lateral recess, foraminal and combined. 68 patients underwent NRB by an ESP (Extended Scope Physiotherapist). 37 females, 31 males, mean age 75 years (range 23–87). Their stenosis was categorized as either lateral recess (n=43), foraminal (n=18), or combined (n=7) on MRI scan evaluation by 2 reviewers. Roland Morris Disability Questionnaire and Visual Analogue Scores were recorded pre-injection and 6 weeks post injection. 2 year final outcome was recorded with an ‘in-house’ questionnaire. 2 year outcome: Lateral recess stenosis: 37% had surgery, 40% required no further treatment. In foraminal stenosis: 17% had surgery, 50% required no further treatment. Combined pathology: 43% had surgery, 57% required no further treatment. Patients requiring no further treatment rated their 2 year outcome as satisfactory symptom control. Of the whole group 15% required a repeat injection, 7% were referred to pain clinic and one patient had died.Purpose of study and background
Methods and results
To study the relationship between Zygoapophysial Joint Tropism and pathologic fractures affecting lumbar and thoracic vertebrae in elderly patients. The sagittal plane orientation of the Zygoapophysial joints (facets or ZAJ) of 324 vertebrae of 63 patients were measured on MRI scans, stratified into lumbar and thoracic, fractured and non-fractured, and then classified according to the presence of tropism. The correlation between tropism and fractures, demographics pertaining to age, spinal level, and morbidity were studied.Purpose
Methods
In the majority of low back pain (LBP) patients a definitive cause for back pain cannot be established; consequently, many patients report feeling uncertain about their diagnosis. They also experience pain-related guilt, which can be divided into: social guilt, managing pain guilt and verification of pain guilt. This study aimed to test a theoretical (causal) model, which proposed that diagnostic uncertainty leads to pain-related guilt, which leads to depression, anxiety and finally to disability. Structural equation modelling was employed to test this model on 438 participants with LBP. The model demonstrated an adequate to good fit with the data. Diagnostic uncertainty predicts all three types of guilt. Verification of pain guilt predicts disability, managing pain guilt predicts anxiety, while social guilt was the strongest predictor of negative outcomes, predicting depression, anxiety and disability.Purpose of the study and background
Summary of the methods used and the results
Leg pain frequently accompanies low back pain and is associated with increased levels of disability and higher health costs than simple low back pain. Distinguishing between different types of low back- related leg pain (LBLP) is important for clinical management and research applications. The aim of this systematic review was to identify, describe and appraise papers that classify or subgroup populations with LBLP. The search strategy involved nine electronic databases including Medline and Embase, reference lists of eligible studies and relevant reviews. Selected papers were quality appraised independently by two reviewers using a standardised scoring tool.Background
Methods
To measure the prevalence, type and instigator of verbal interruptions during initial consultations between clinicians and patients with low back pain. During initial consultations, patients take on average, 92 seconds to outline their problem, if given the chance. Few achieve this, with clinicians interrupting (25–69% of cases) in as little as 12 seconds, either with an ‘overlap’, (a projection error of when a turn ends), or an ‘interruption’ (a start-up before the speaker's talk is complete). The prevalence and impact of these in back pain consultations is unknown.Purpose
Background
Implementation fidelity is the extent to which an intervention is delivered as intended by intervention developers, and is extremely important in increasing confidence that changes in study outcomes are due to the effect of the intervention itself and not due to variability in implementation. Growing demands on healthcare services mean that multiple condition interventions involving highly prevalent musculoskeletal pain conditions such as chronic low back pain (CLBP) and/or osteoarthritis (OA) are of increasing clinical interest. This is the first in-depth review of implementation fidelity within self-management interventions for any musculoskeletal pain condition. Structured self-management interventions delivered by health-care professionals (including at least one physiotherapist) in a group format involving adults with OA of the lumbar spine, hip or knee and/or CLBP were eligible for inclusion. The National Institutes of Health Behaviour Change Consortium Treatment Fidelity checklist was used by two independent reviewers to assess fidelity.Background
Methods
The primary aim of this pilot study was to assess and evaluate the SpineCor Pain Relief Brace as a method of reducing the pain experienced by patients diagnosed with degenerative scoliosis Participants (n=24) with an average age of 67 (+/− 8) old that fulfilled the study inclusion criteria were randomly allocated into either a treatment or control group. Both sets of participants received questionnaires (ODI, SF 36v2 and EQ5D-5L) at 1,3,6,9 and 18 months. In addition to the questionnaires the treatment group also received the SpineCor Pain Relief Brace and took part in a semi structured interview.Aim
Method
Osteoarthritis (OA) and chronic low back pain (CLBP > 12 weeks duration) are two of the most common and costly chronic musculoskeletal conditions globally. Healthcare service demands mean that group-based multiple condition interventions are of increasing clinical interest and a priority for research, but no reviews have evaluated the effectiveness of group-based physiotherapy-led self-management interventions (GPSMI) for both conditions concurrently. Rapid review methodologies are an increasingly valid means of expediting knowledge dissemination and are particularly useful for addressing focused research questions. The electronic databases of MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews and Cochrane Register of Controlled Trials were searched from the earliest date possible to August 26th 2013. Structured group-based interventions that aimed to promote self-management and that were delivered by health-care professionals (including at least one physiotherapist) involving adults with OA and/or CLBP were eligible for inclusion. The screening and selection of studies, data extraction and risk of bias assessment were conducted independently by two reviewers.Background
Methods
To assess the safety of day case lumbar decompressive surgery Retrospective study of 233 consecutive patients undergoing DCLDS who were identified from a prospective electronic database.Aim
Method
This study investigates the role of the patient and the therapeutic relationship with their medical practitioner in resolving CLBP (chronic low back pain). Many cases of chronic pain persist due to the stress response. The body is equipped with natural self-healing mechanisms that must be activated by the patient. This needs facilitation by someone trained to engage the patient in this process. Evidence shows that conventional medication; surgery and physical rehabilitation do not always resolve chronic pain. To ensure that the stress response doesn't sabotage biomedical intervention the patient may need to address any problems obstructing a healthy lifestyle. This means supporting healthy relationships, and good health in other areas such as: professional life, financial matters, beliefs and creativity. Recent Case Studies are described where patients presented with severe CLBP. The Roland Morris Low Back Pain Disability Questionnaire was used to measure outcomes. Treatment included education about the ANS (autonomic nervous system); an active health plan in which the patient takes responsibility for their own healing; and movement guidelines to support the parasympathetic NS. The results show a significant pain reduction and increase in mobility.Purposes of Study and Background
Summary of Methods used and Results
To use Patient Reported Outcome Measures (PROMs) to determine the effectiveness of lumbar spinal surgery at a single UK institution. Consecutive patients who underwent lumbar spinal surgery (discectomies or decompressions) from 1 January 2011 to 13 March 2013 at a UK District General Hospital were assessed. The procedures were performed or supervised by a senior Consultant Orthopaedic spinal surgeon. All patients completed PROM questionnaires before and three months following surgery. These included Visual Analogue Scores (VAS), SF-12, Oswestry Disability Index (ODI) and Roland Morris Low Back Pain Questionnaire (RMQ).Aim
Methods
To assess the safety of Zero Profile Interbody fusion (Zero P) device in Anterior Cervical Decompression and fusion (ACDF) for degenerative cervical stenosis. 89 consecutive patients treated with Zero P interbody device from September 2009 to September 2012 were included in this retrospective study. Inclusion criterion: degenerative cervical stenosis with myelopathy, persistent radiculopathy after at least 3 months of failed conservative management. Exclusion criterion: Paediatric population; patients with infection, metastatic disease and trauma. There were 39 females, 50 males with mean age of 55 (ranging from 24 to 84 years) 56 (64%) had surgery at 1 level, 31 (35%) at 2 levels, 1 (1%) at 3 levels. Total number of levels operated were 121. Common levels operated were C56 (62%) and C67 (47%) Majority were operated due to radicular symptoms, 56 (64%) had radicular symptoms, 28(31%) had myelopathy and 5 (5%) MyeloradiculopathyAim
Method
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. To evaluate the efficacy of OSRAS through a prospective audit.Introduction
Aim
This audit report outlines a physiotherapy lead spinal triage program for inpatients in a private hospital. The reason to trial this model was proposed as a way to expedite the assessment of inpatients presenting with back pain and implement an appropriate and prompt management plan. An audit tool was developed to record the patient details and outcomes of referrals to the spinal triage program. Length of time between referral and triage was recorded as was the number of patients that went on to require a spinal surgeon consult and spinal intervention. A total of 75 patients were referred into Spinal Triage over a 7 month period. The majority of in patients referred for spinal consult within this private hospital setting were triaged solely by physiotherapy (56%) and a management plan decided on in conjunction with the spinal surgeon on call who could access any imaging remotely. Six patients (8%) involved in the triage program went on to have spinal surgical intervention.Purpose of the study and background
Summary of the methods used and the results
60% of back pain patients report pain radiation in the leg(s), which is associated with worse symptoms and poorer recovery. The majority are treated in primary care, but detailed information about them is scarce. The objective of this study is to describe the characteristics of patients with back and leg pain-seeking treatment in primary care. Adult patients consulting their GP with back and leg pain were invited to the study. Participants completed questionnaires including sociodemographic, physical and psychosocial measures. They also underwent standardised clinical assessments by physiotherapists, and received an MRI scan.Background
Methods
Low birth weight is related to decreased lumbar spine vertebral canal size and bone mineral content later in life, suggesting that antenatal factors affect spine development. The purpose of this study was to explore associations between antenatal factors and lumbar spine morphology in childhood. Antenatal data and supine MR images of the lumbar spine were available for 161 children. Shape modelling, using principle components analysis, was performed on mid-sagittal images to quantify different modes of variation in lumbar spine shape. Previously collected measures of spine canal dimensions were analysed.Purpose and Background
Methods
The factors influencing normal spine curvature in midlife are unknown. We performed an MR and plain radiograph study on well characterised, unselected twin volunteers from the TwinsUK register ( T2 weighted MR scans and long spine standing radiographs were obtained at the same morning visit on twin pairs. Midline sagittal MR images were coded for 4 degenerative features. SpineviewTM software was applied plain films and calculated the angles of curvature. A classical twin study was performed. Multivariate regression analysis was used to determine the association between spine curves, LDD and confounders (age, body mass index).Background
Methods
The authors recognised that patients presenting to the Orthopaedic Spinal Rapid Access Service with symptoms and or signs of cauda equina syndrome may not have the diagnosis confirmed radiologically. Altered sensation in the ‘saddle area’, bilateral sciatica, urinary incontinence or retention, altered bowel habit, and sexual dysfunction are well recognised symptoms of cauda equina syndrome. Recognised side-effects of neuropathic medications commonly prescribed for radicular pain include: altered sensation, urinary incontinence or retention, and sexual dysfunction. We have undertaken a retrospective cohort analysis in order to identify the relationship between prescribed medications and presenting symptoms and signs. 151 patients were referred to the service within a 6 month period. Case notes of 34 patients presenting with symptoms and or objective signs of CES in absence of positive radiological findings were reviewed. Data collected included the patient's age, sex, prescribed medications and presenting symptoms.Introduction
Method
To identify methods used to measure free living sedentary behaviour in people with back pain and review the validity and reliability of identified measures. Databases including CINAHL, EMBASE, MEDLINE, AMED, PsycINFO, SPORTDiscus and the Sedentary Behaviour and Research Network website (Background and purpose
Methods
Differences in regional lumbar angles in sitting have been observed between subgroups of NSCLBP patients exhibiting motor control impairments (MCI) (O'Sullivan, 2005; Dankaerts et al, 2006). However, differences in standing posture and other spinal regions are unknown. This study aimed to compare regional spinal angles in healthy and MCI subgroups in sitting and standing. An observational, cross-sectional study investigated spinal kinematics of 28 Flexion Pattern (FP), 23 Active Extension Pattern (AEP) (O'Sullivan, 2005) and 28 healthy controls using 3D motion analysis (Vicon) during usual sitting and standing. Mean sagittal angle for Total Lumbar (TotLx), Total Thoracic (TotTx), Upper Thoracic (UTx), Lower Thoracic (LTx), Upper Lumbar (ULx) and Lower Lumbar (LLx) regions between groups were compared using one-way ANOVA.Background and Purpose of Study:
Methods:
Low back pain (LBP) is widespread in all populations and is a worldwide health problem, which poses substantial challenges for clinical management. Individuals with LBP may reduce their symptoms by implementing self-managed at-home interventions. The theoretical design of the LumbaCurve™ promotes the principles of a passive gravity-assisted traction (PGAT) stretch of the lumbar and sacral region in order to reduce LBP. This study aimed to assess the clinical effectiveness of the LumbaCurve™ in the management of LBP when compared to a control group of standardised care. Following a screening form using Red Flags and STarT Back tools, 60 individuals with LBP were recruited to the 4-week intervention. Eligible participants completed a pre-intervention questionnaire and were randomly allocated to either ‘standardised care’ or ‘standardised care PLUS LumbaCurve™’ group. Intervention material was trialled for 4 weeks consecutively, followed by a post-intervention questionnaire. Pre and post assessments applied the Roland Morris Disability Questionnaire (RMDQ), Patient Reported Outcome Measures (PROMS).Background
Methods
This paper describes the outcomes obtained from a 12 hour group based multidisciplinary functional restoration programme for patients with persistent low back pain who presented with psychosocial obstacles to recovery. The programme was designed to address modifiable psychosocial obstacles to recovery over a four week period, reduce pain related disability, improve pain self-efficacy and reduce patients' reliance on analgesic medication. A single group retrospective analysis.Objectives
Design
Chronic low back pain (CLBP) can be constant or episodic. Fluctuations are common. We present two different pictures of the CLBP experience; timelines illustrating back pain over time and ‘web diagrams’ showing a snapshot of a phase in time. Semi structured interviews from 34 participants from the UK BeST trial included timelines drawn collaboratively by the researcher and participant. Symptoms, events, treatment and consultations were arranged chronologically along a timeline. Initial thematic analysis on 63 interviews gave bio-psychosocial themes that were spoken about in an integrated way. Further analysis explored these interactions between themes. Interactions were classified as; helpful to recovery, unhelpful or mixed. Web diagrams were drawn for each interview and classified as Dense- mostly unhelpful interactions, Open – a combination of helpful and unhelpful interactions and Sparse – mostly helpful interactions.Background and Purpose
Methods
Back pain impinges upon all aspects of life, has a reported UK lifetime prevalence as high as 84% and considering approximately a third of our lives are spent asleep the paucity of research into the effect a mattress has on back pain and sleep is surprising. Mood changes, effecting an increase in pain perception, due to sleep loss may also lead to a downward spiral of increasing back pain and greater sleep loss. A controllable factor in this spiral, affecting both aspects, is the mattress but to the authors' knowledge none currently available on the market have any robust, published research to objectively support any claims made and at best being ‘endorsed’ by experts. This may lead to possible misinterpretation of efficacy and leave professionals at a loss with what to advise when questioned. Method: A three month, randomised, controlled, double blind crossover field study is proposed to take place in the participants own homes, ensuring the most natural sleep environment. Data collection: Three 28 day phases 1 - Baseline data, participants sleeping on their own mattress 2 - Random allocation of mattresses, half allocated test and half control 3 - Crossover of test and control mattress Subjective measures of back pain and sleep quality will be collected utilising a daily sleep diary and visual analogue scales. Objective measures of sleep quality using activity monitors during sleep.Purpose and Background
Methods and Data collection
Being involved in litigation is associated with poor outcomes, higher levels of pain, disability, catastrophising, fear-avoidance and other psychological factors. Poor access to treatments can contribute to chronicity of symptoms and poor outcomes, especially in patients involved in litigation with a longer time since the accident. To examine the relationship between time since the accident, access to treatments and current psychological variables.Background
Purpose
To assess implant performance, to evaluate fusion and to assess clinical and radiologic outcome of circumferential fusion using porous tantalum cages for ALIF in a 360-degree fusion. A retrospective cohort study was performed over a 4-year period that included the implantation of 280 tantalum cages in 98 patients by the technique of anterior lumbar interbody fusion (ALIF) and posterolateral spondylodesis. Radiographic follow-up was performed to document any implant related problems. Preoperative and postoperative clinical outcome measures were assessed. No neurological, vascular or visceral injuries were reported. There were no rod breakages and no symptomatic non-unions. One revision procedure was performed for fracture. Mean VAS back pain score in our patient cohort improved from 7.5 preoperatively to 1.9 at latest follow-up, mean VAS leg pain score improved from 6.2 to 1.1 and mean ODI score improved from 51.1 to 18.3. Porous tantalum cages have high strength and flexibility, in addition to having similar biomaterial properties to cancellous bone. Their use in 360-degree spondylodesis to treat degenerative lumbar spine deformity has been demonstrated to be very safe and effective, with excellent clinical and functional outcomes.
To evaluate the incidence of complications and the radiographic and clinical outcomes from 2-stage reconstruction including 3-column osteotomy for revision adult spinal deformity. A prospective cohort study performed over 2 years at a major tertiary referral centre for adult spinal deformity surgery. All consecutive patients requiring 2-stage corrective surgery for revision adult spinal deformity were included. Radiographic parameters and clinical outcome measures were collected preoperatively and at 6 weeks, 6 months, 1 year and 2 years postoperatively. Radiographic parameters analysed included pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis and sagittal vertical axis. Clinical outcome measures collected included EQ-5D, ODI, SRS 22 and VAS Pain Scores. Performing anterior column reconstruction followed by 3-column osteotomy and extension of instrumentation for revision spinal deformity resulted an excellent correction of sagittal alignment, minimal surgical complications and significant improvements in HRQOL. Restoration of lumbar lordosis, pelvic tilt and sagittal vertical axis were observed in addition to postoperative improvements in EQ-5D, ODI, SRS 22 and VAS Pain Scores at follow-up. Performing anterior column reconstruction prior to a 3-column osteotomy minimises complications associated with 3-column osteotomy and extension of posterior instrumentation. We propose a treatment algorithm for safe and effective treatment in revision adult deformity surgery.
To assess the clinical and radiologic outcome of MM patients with thoracic spine involvement and concomitant pathologic sternal fractures with a resultant severe sagittal plane deformity. A prospective cohort study (n=391) was performed over a 7-year period at a national tertiary referral centre for the management of multiple myeloma with spinal involvement. Clinical, serological and pathologic variables, radiologic findings, treatment strategies and outcome measures were prospectively collected. Pre-treatment and post-treatment clinical outcome measures utilised included EQ-5D, VAS, ODI and RMD scoring systems. 13 MM patients presented with a severe symptomatic progressive sagittal plane deformity with a history of pathologic thoracic compression fractures and concomitant pathologic sternal fracture. All patients with concomitant sternal fractures displayed the radiographic features and spinopelvic parameters of positive sagittal malalignment and attempted clinical compensation. All patients had poor health related quality of life measures when assessed. Pathologic sternal fracture in a MM patient with thoracic compression fractures is a risk factor for the development of a severe thoracic kyphotic deformity and sagittal malalignment. This has been demonstrated to be associated with a very poor health related quality of life.
To examine the impact of a structured rehabilitation programme as part of an integrated multidisciplinary treatment algorithm for adult spinal deformity patients. A prospective cohort study was performed over a 2-year period at a major tertiary referral centre for adult spinal deformity surgery. All consecutive patients requiring 2-stage corrective surgery for sagittal malalignment were included (n=32). Details of physiotherapy initial evaluation, inpatient rehabilitation progress, details of bracing treatment and time to discharge were collected. Clinical outcome scores were measured preoperatively and at 6 weeks, 6 months and 1 year postoperatively. After second stage corrective surgery, the mean time to standing without assistance was 2.1 days, mean time to independent ambulation was 4.2 days, mean time to competent ascending and descending stairs was 5.6 days and mean time to moulded orthosis application 7.1 days. Successful progression through the structured rehabilitation programme was associated with high clinical outcome scores and improved health related quality of life (HRQOL). The introduction of this programme contributed to the development of an enhanced recovery pathway for patients having adult spinal deformity surgery, reducing inpatient length of stay and optimising clinical outcomes.
Neural axis anomalies in idiopathic scoliosis (AIS) are well documented, with prevalence of 7% in adolescents; 20% in early-onset and up to 40% in congenital, the case for pre-operative MRI of brainstem to sacrum is well made in these groups. SK is rarer than AIS and the prevalence of anomalies is not defined. The case for routine MRI scan is unclear. A recent report concluded that routine MRI was not indicated, although this was based on only 23 MRI scans in 85 patients. At our institution all patients are undergo whole spine MRI following a diagnosis of SK. We aimed to assess the incidence of significant neural anomalies in Scheuermann's Kyphosis. Using a keyword search for “Scheuermann”, we reviewed all SK patients' MRI reports over the past 6 years. 117 MRI scans were identified. 13 patients did not fulfil the radiological criteria for SK and thus 104 (73M: 31F) scans were reviewed. 14 (13%) of 104 scans showed unexpected Significant abnormal findings. There were 8 (8%) with neural axis anomalies: 4 syrinxes; 1 cord anomaly; 2 cerebellar descents and 1 cerebellar tumour. All these patients had normal neurological examination except one with examination consistent with a known diagnosis of Parkinson's. A further 6 patients had non-neural anomalies. The presence of neural axis anomalies may influence the management of a patient with SK. Neurological compromise during correction is higher in patients with neural axis anomalies and this risk can often be partially mitigated by a preceding neurosurgical procedure (such as foramen magnum decompression or shunt). Furthermore it is well described that these anomalies often occur in patients who demonstrate a normal neurological examination. This study confirms this. Given that MRI is widely available and considering the devastating life implications of neurological injury, we advise pre-operative MRI scan in all SK patents.
This study aimed to verify the accuracy of the DIERS Formetric Scan when assessing vertebral rotation of the apical vertebrae in Adolescent Idiopathic Scoliosis (A.I.S) patients, to determine whether the DIERS Formetric Scans can be used instead of or alongside radiographs when assessing A.I.S patients. Both the radiographs and the DIERS Formetric Scans of 60 Preoperative A.I.S patients. All patients included in our study had predominant thoracic curves using the Lenke classification method, Cobb angle range 33° – 85°. Each radiograph was categorised into groups according to the severity of Nash-Moe rotation score of the apical vertebrae. Three groups were formed Nash-Moe +1 (20 patients), Nash-Moe +2 (27 patients), Nash-Moe +3 (13 patients). Each result was then compared to the maximal rotation analysed by the DIERS Formetric Scan, which took place on the same day as the radiographs. The results were then assessed using a Pearson Correlation Coefficient and a One-Way ANOVA with Post-Hoc Tukey HSD Analysis. The Nash-Moe +1 Group scored a mean maximal rotation of 14.65° ±6.56 (11.82 – 17.48) (95% Confidence Interval), Nash-Moe +2 mean maximal rotation was 19.6° ±7.1 (16.92 – 22.28) and Nash-Moe +3 scored 21.53° ±8.9 (16.99 – 26.37). The Pearson Correlation Coefficient of this assessment was +0.342 (p value 0.07) demonstrating a weak positive correlation. The One-Way ANOVA analysis with Post-Hoc Tukey HSD analysis. The results of this analysis was an F value score of +4.115 (p Value 0.021) for the overall One-Way ANOVA test. The Post-Hoc Tukey HSD tests demonstrate that there is a statistical difference between Group 1 and Group 3 (p value 0.030) but there is no statistical difference between Group 1 and Group 2 (p value 0.068) as well as no statistical difference between Group 2 and Group 3 (p value 0.716). DIERS Formetric Scan assessment of vertebral rotation shows a positive correlation with the Nash-Moe method. This allows us to rely on the Formetric scans and thus a possible reduction in radiographs when assessing A.I.S, this reduces the exposure to ionising radiation in A.I.S patients.
The use of serial casting in the management of early onset scoliosis (EOS) has been well described. Our aim was to evaluate outcomes of plaster jacket therapy in patients with EOS from a tertiary referral centre. A retrospective review of hospital records and PACS images of 27 patients to identify patients treated with serial casting over a five year period. The primary outcome measure was the need for surgical intervention, with change in Cobb angle used as a secondary outcome measure Mean age at presentation was 14 months (range 10 – 42), including 14 male and 13 female patients, with an average follow-up of 34 months. Curves were categorised according to aetiology: 16 idiopathic, 6 syndromic, 3 congenital and 2 neuromuscular curves. The mean Cobb angle at diagnosis was 43.7° (range 22 – 115) and mean rib vertebral angle difference (RVAD) was 22.2° (8 – 70). Duration of treatment was 9.9 months (range 3 – 27), with an average of two plaster jacket changes per child. At the time of review, patients fell into one of three groups. Group one (10 patients) failed conservative treatment due no improvement in Cobb angle (mean 48.4° compared with pre-op 53.9°, p value 0.55) and either had insertion of growing rods or had been listed for this procedure, at a mean age of 51.8 months. Group two (12 patients) had a mean Cobb angle of 38.9° pre-treatment which improved to 23.5° (p value <0.05) and were either treated in a brace or had discontinued treatment. The mean RVAD at initial diagnosis was 36.6° in group 1 compared with 13.8° in group 2 (p<0.05). All patients in group one requiring surgical treatment had an RVAD of greater than 20°. Serial casting is on-going for five patients (group three). Complications occurred in 30% of patients including pressure sores, chest infection and respiratory compromise requiring intubation. Current NICE guidance recognises that serial casting ‘rarely corrects scoliosis’ but recommends it may be used ‘to allow growth before a more permanent treatment is offered’. In our experience, serial casting did not allow any patients with a progressive scoliosis (determined by an RVAD of greater than 20°), to reach a single definitive fusion. However serial casting appeared to halt to curve progression until the child was suitable for the insertion of a growing rod system.
