Aims. The aim of this study was to determine the diagnostic utility of histological analysis in spinal biopsies for spondylodiscitis (SD). Patients and Methods.
Background. Endplate defect is an MRI trait, found to be associated with intervertebral disc degeneration. There is a lack of understanding regarding the mechanism underlying lumbar disc degeneration (LDD). This large-scale longitudinal population-based study aimed to determine the order of appearance of degenerative change in the vertebral body and intervertebral disc, the influence of endplate degeneration on LBP and whether there is a genetic influence on endplate damage. Methods. Individuals from the TwinsUK spine study having longitudinal T2-weighted lumbar MRI scans at baseline (n=996) and a decade later (n=438) were included. LDD, vertebral endplate defect expressed as a total endplate (TEP) score and Modic change (MC) were assessed using standard techniques. Mixed-effects models were used to determine the association between spine
Patients with cauda equina syndrome (CES) require emergency imaging and surgical decompression. The severity and type of symptoms may influence the timing of imaging and surgery, and help predict the patient’s prognosis. Categories of CES attempt to group patients for management and prognostication purposes. We aimed in this study to assess the inter-rater reliability of dividing patients with CES into categories to assess whether they can be reliably applied in clinical practice and in research. A literature review was undertaken to identify published descriptions of categories of CES. A total of 100 real anonymized clinical vignettes of patients diagnosed with CES from the Understanding Cauda Equina Syndrome (UCES) study were reviewed by consultant spinal surgeons, neurosurgical registrars, and medical students. All were provided with published category definitions and asked to decide whether each patient had ‘suspected CES’; ‘early CES’; ‘incomplete CES’; or ‘CES with urinary retention’. Inter-rater agreement was assessed for all categories, for all raters, and for each group of raters using Fleiss’s kappa.Aims

Introduction purpose and background. Implicit in the diagnosis of CES is the presence of leg pain with a spectrum of bladder and/or bowel disturbance and/or peri-anal sensory loss. Current research describes the
The aim of this study was to report the long-term prognosis of patients with multiple Langerhans cell histiocytosis (LCH) involving the spine, and to analyze the risk factors for progression-free survival (PFS). We included 28 patients with multiple LCH involving the spine treated between January 2009 and August 2021. Kaplan-Meier methods were applied to estimate overall survival (OS) and PFS. Univariate Cox regression analysis was used to identify variables associated with PFS.Aims

Purpose of the Study. To develop an online self-assessment and self-management tool (BACKonLINE™) for discerning between people with characteristics of predominantly centrally (CD) or peripherally (PD) driven LBP. Background. Low back pain (LBP) may worsen with time, making appropriate treatment important. In the NHS Physiotherapy services LBP patients may wait for 14–24 weeks for treatments. Many factors contribute to LBP, but it is predominantly initially viewed as a result of peripheral tissue damage. However, evidence show that persistent LBP is associated with amplification in pain processing in the central nervous system (central sensitisation). Sometimes, this may drive symptoms, resulting in poorer outcomes and requiring longer management. Timely assessment and appropriate management is therefore paramount. Method. Design: 2-round Delphi study. Sample: Purposive sample of international LBP physiotherapy experts. For Round1, series of questions were developed using literature search on characterising
The aim of the study was to determine if there was a direct correlation between the pain and disability experienced by patients and size of their disc prolapse, measured by the disc’s cross-sectional area on T2 axial MRI scans. Patients were asked to prospectively complete visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores on the day of their MRI scan. All patients with primary disc herniation were included. Exclusion criteria included recurrent disc herniation, cauda equina syndrome, or any other associated spinal pathology. T2 weighted MRI scans were reviewed on picture archiving and communications software. The T2 axial image showing the disc protrusion with the largest cross sectional area was used for measurements. The area of the disc and canal were measured at this level. The size of the disc was measured as a percentage of the cross-sectional area of the spinal canal on the chosen image. The VAS leg pain and ODI scores were each correlated with the size of the disc using the Pearson correlation coefficient (PCC). Intraobserver reliability for MRI measurement was assessed using the interclass correlation coefficient (ICC). We assessed if the position of the disc prolapse (central, lateral recess, or foraminal) altered the symptoms described by the patient. The VAS and ODI scores from central and lateral recess disc prolapses were compared.Aims

Background:. 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. Methods:. 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. Results:. LICs originated at levels from L1-S2 (61.5% at L4/5), reaching 17mm. 2. (rapid one year progression in this case). LICs were described as synovial in all but two cases (hemorrhagic cyst; Tarlov perineural cysts). Background degenerative changes were reported in 88.5% of cases. Patients described up to 30-year histories of non-specific back pain.
The aims of this study were to determine the diagnostic yield of image-guided biopsy in providing a final diagnosis in patients with suspected infectious spondylodiscitis, to report the diagnostic accuracy of various microbiological tests and histological examinations in these patients, and to report the epidemiology of infectious spondylodiscitis from a country where tuberculosis (TB) is endemic, including the incidence of drug-resistant TB. A total of 284 patients with clinically and radiologically suspected infectious spondylodiscitis were prospectively recruited into the study. Image-guided biopsy of the vertebral lesion was performed and specimens were sent for various microbiological tests and histological examinations. The final diagnosis was determined using a composite reference standard based on clinical, radiological, serological, microbiological, and histological findings. The overall diagnostic yield of the biopsy, and that for each test, was calculated in light of the final diagnosis.Aims

Background. 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. Methods. 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. Results. Of 13,337 potential eligible citations, 49 relevant papers were identified that reported on 20 classification systems. Papers were grouped according to purpose and criteria of the classification systems. Five themes emerged: (i) pathoanatomical sources of pain (ii)
Thoracic spinal cord herniation is a relatively uncommon syndrome of anterior hemi cord dysfunction. However it has been reported in literature with increasing frequency over the last decade. Since the initial description of this clinical entity by Weitzman et al. in 1974, more than 100 cases have been described. Although
Background. Low back pain is a common condition amongst Armed Services personnel and can have significant impact upon their ability to undertake military duties, including being deployed into austere environments. Methods and results. This was a qualitative study of 16 military physiotherapists exploring their attitudes and beliefs towards management of low back pain. Semi-structured interviews were conducted and transcribed. The transcripts were analysed using a method of thematic content analysis. Six themes were identified; military culture, occupational issues, continuing professional development, clinical reasoning, need for a cure and labelling the patient. The highly challenging occupational demands placed on military patients appeared to prompt physiotherapists to request radiological investigations at an earlier stage than recommended in current guidelines. Justification for early investigation was considered to be both in the patients' and the Armed Services best interests, for the patient to initiate treatment with minimum delay whilst also decreasing the number of personnel unable to deploy for medical reasons. Conclusion. Obtaining investigative procedures at an early stage of the patients' management was justified by reference to the highly demanding physical duties undertaken by service personnel. The military physiotherapists' were very well informed about occupational demands placed on their patients; in this instance results from radiological investigations were used to inform not only the clinical management but more significantly the occupational management. The military physiotherapists regard for the significance of occupational factors sets them apart from those in civilian practice where management is predominantly based on
Clinical and radiological indicators of outcome in the use of X-Stops were sought by evaluating patient-centred outcomes alongside radiographic scrutiny of changes around implants with correlation to outcome. Prospectively collated outcome scores were correlated to outcome, with retrospective analysis of pre-operative MRI scans and 117 post-operative radiographs. Single surgeon series of 44 patients(52 implants). Clinical - ODI, walking distance, Low Back Outcome Score, MZDI and MSP. Radiographic - lucency(anterior and cranio-caudal to implant), coronal rotation, dorsal migration of implant. Failure defined by persistent symptoms requiring removal+/−decompression. Pre-operative features of success: lower ODI(p<0.05), higher LBOS(p<0.01), higher walking distance(p<0.01), lower MZDI(p<0.01). Marked differences were noted in post-operative scores for the two cohorts. An eight-fold improvement in walking distance in success patients compared to an increase to 1.8 times the baseline in failures. ODI improved ten times more in the success group at 20 cf2(failure). MZDI improvement was greater in the revisions at 2.2 cf 0.9 in successes. Ranking Pearson's coefficient of radiograph measurements in success and failure cohorts, revealed failure associated most to anterior lucency(R=0.93), rotation(R=-0.61), cranio-caudal lucency (R=-0.29) and migration (R=-0.25). Success most associated to rotation (R=-0.22). Failure radiographs revealed greater lucency cranio-caudal and ventral to the implant, more coronal rotation, and pronounced dorsal migration.
Diagnosis of cauda equina syndrome (CES) remains difficult; clinical assessment has low accuracy in reliably predicting MRI compression of the cauda equina (CE). This prospective study tests the usefulness of ultrasound bladder scans as an adjunct for diagnosing CES. A total of 260 patients with suspected CES were referred to a tertiary spinal unit over a 16-month period. All were assessed by Board-eligible spinal surgeons and had transabdominal ultrasound bladder scans for pre- and post-voiding residual (PVR) volume measurements before lumbosacral MRI.Aims

Spinal tuberculosis (TB) remains an important concern. Although spinal TB often has sequelae such as myelopathy after treatment, the predictive factors affecting such unfavourable outcomes are not yet established. We investigated the clinical manifestations and predictors of unfavourable treatment outcomes in patients with spinal TB. We performed a multicentre retrospective cohort study of patients with spinal TB. Unfavourable outcome was defined according to previous studies. The prognostic factors for unfavourable outcomes as the primary outcome were determined using multivariable logistic regression analysis and a linear mixed model was used to compare time course of inflammatory markers during treatment. A total of 185 patients were included, of whom 59 patients had unfavourable outcomes.Aims
Patients and Methods
Early cases of cauda equina syndrome (CES) often present with nonspecific symptoms and signs, and it is recommended that patients undergo emergency MRI regardless of the time since presentation. This creates substantial pressure on resources, with many scans performed to rule out cauda equina rather than confirm it. We propose that compression of the cauda equina should be apparent with a limited sequence (LS) scan that takes significantly less time to perform. In all, 188 patients with suspected CES underwent a LS lumbosacral MRI between the beginning of September 2017 and the end of July 2018. These images were read by a consultant musculoskeletal radiologist. All images took place on a 3T or 1.5T MRI scanner at Stoke Mandeville Hospital, Aylesbury, UK, and Royal Berkshire Hospital, Reading, UK.Aims

The purpose of this study was to investigate the prevalence of
sarcopenia and to examine its impact on patients with degenerative
lumbar spinal stenosis (DLSS). This case-control study included two groups: one group consisting
of patients with DLSS and a second group of control subjects without
low back or neck pain and related leg pain. Five control cases were
randomly selected and matched by age and gender (n = 77 cases and
n = 385 controls) for each DLSS case. Appendicular muscle mass,
hand-grip strength, sit-to-stand test, timed up and go (TUG) test,
and clinical outcomes, including the Oswestry Disability Index (ODI)
scores and the EuroQol EQ-5D were compared between the two groups.Aims
Patients and Methods
The aim of this study was to determine whether chilled irrigation
saline decreases the incidence of clinical upper limb palsy (ULP;
a reduction of one grade or more on manual muscle testing; MMT),
based on the idea that ULP results from thermal damage to the nerve
roots by heat generated by friction during bone drilling. Irrigation saline for drilling was used at room temperature (RT,
25.6°C) in open-door laminoplasty in 400 patients (RT group) and
chilled to a mean temperature of 12.1°C during operations for 400
patients (low-temperature (LT) group). We assessed deltoid, biceps,
and triceps brachii muscle strength by MMT. ULP occurring within
two days post-operatively was categorised as early-onset palsy.Aims
