Background and Purpose. The UK's NIHR and Australia's NHMRC have funded two randomised controlled trials (RCTs) to determine if lumbar fusion surgery (LFS) is more effective than best conservative care (BCC) for adults with persistent, severe low back pain (LBP) attributable to lumbar spine degeneration. We aimed to describe clinicians’ decision-making regarding suitability of patient cases for LFS or BCC and level of equipoise to randomise participants in the RCTs. Methods. Two online cross-sectional surveys distributed via UK and Australian professional networks to clinicians involved in LBP care, collected data on clinical discipline, practice setting and preferred care of five patient cases (ranging in age, pain duration, BMI, imaging findings, neurological signs/symptoms). Clinicians were also asked about willingness to randomise each patient case. Results. Of 174 responses (73 UK, 101 Australia), 70 were
Aims. The current pandemic caused by COVID-19 is the biggest challenge for national health systems for a century. While most medical resources are allocated to treat COVID-19 patients, several non-COVID-19 medical emergencies still need to be treated, including vertebral fractures and spinal cord compression. The aim of this paper is to report the early experience and an organizational protocol for emergency spinal surgery currently being used in a large metropolitan area by an integrated team of
Purpose. This research project explored the experiences, attitudes, beliefs, and perceptions of healthcare professionals (physiotherapists and orthopaedic surgeons) and people with chronic low back pain (CLBP) regarding the barriers and facilitators to activity normalisation following physiotherapy. Methods. A qualitative study of the perspectives of patients, physiotherapists and
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

The aim of this study was to evaluate whether, after correction of an adolescent idiopathic scoliosis (AIS), leaving out the subfascial drain gives results that are no worse than using a drain in terms of total blood loss, drop in haemoglobin level, and opioid consumption. Adolescents (aged between 10 and 21 years) with an idiopathic scoliosis (major curve ≥ 45°) were eligible for inclusion in this randomized controlled noninferiority trial (n = 125). A total of 90 adolescents who had undergone segmental pedicle screw instrumentation were randomized into no-drain or drain groups at the time of wound closure using the sealed envelope technique (1:1). The primary outcome was a drop in the haemoglobin level during first three postoperative days. Secondary outcomes were 48-hour postoperative oxycodone consumption and surgical complications.Aims

The optimal procedure for the treatment of ossification of the posterior longitudinal ligament (OPLL) remains controversial. The aim of this study was to compare the outcome of anterior cervical ossified posterior longitudinal ligament en bloc resection (ACOE) with posterior laminectomy and fusion with bone graft and internal fixation (PTLF) for the surgical management of patients with this condition. Between July 2017 and July 2019, 40 patients with cervical OPLL were equally randomized to undergo surgery with an ACOE or a PTLF. The clinical and radiological results were compared between the two groups.Aims
Methods
The aims of this study were first, to determine if adding fusion to a decompression of the lumbar spine for spinal stenosis decreases the rate of radiological restenosis and/or proximal adjacent level stenosis two years after surgery, and second, to evaluate the change in vertebral slip two years after surgery with and without fusion. The Swedish Spinal Stenosis Study (SSSS) was conducted between 2006 and 2012 at five public and two private hospitals. Six centres participated in this two-year MRI follow-up. We randomized 222 patients with central lumbar spinal stenosis at one or two adjacent levels into two groups, decompression alone and decompression with fusion. The presence or absence of a preoperative spondylolisthesis was noted. A new stenosis on two-year MRI was used as the primary outcome, defined as a dural sac cross-sectional area ≤ 75 mm2 at the operated level (restenosis) and/or at the level above (proximal adjacent level stenosis).Aims
Methods
Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS.Aims

To determine if the term “back pain” has uniform meaning to spinal surgeons. A survey of specialists attending an international meeting on spinal surgery. Participants were shown 5 schematic pain drawings and then asked to categorize the pain as either back or leg pain. An international cohort of neurosurgeons,
This study addressed two questions: first, does surgical correction of an idiopathic scoliosis increase the volume of the rib cage, and second, is it possible to evaluate the change in lung function after corrective surgery for adolescent idiopathic scoliosis (AIS) using biplanar radiographs of the ribcage with 3D reconstruction? A total of 45 patients with a thoracic AIS which needed surgical correction and fusion were included in a prospective study. All patients underwent pulmonary function testing (PFT) and low-dose biplanar radiographs both preoperatively and one year after surgery. The following measurements were recorded: forced vital capacity (FVC), slow vital capacity (SVC), and total lung capacity (TLC). Rib cage volume (RCV), maximum rib hump, main thoracic curve Cobb angle (MCCA), medial-lateral and anteroposterior diameter, and T4-T12 kyphosis were calculated from 3D reconstructions of the biplanar radiographs.Aims

Venous Thromboembolism (VTE) is the most common complication following major joint surgery. While attention has focused on VTE following joint arthroplasty their exists a gap in the literature examining the incidence of VTE in spinal surgery; with a shortage of epidemiological data, guidelines for optimal prophylaxis are limited. This survey, undertaken at the 2009 BASS Annual Meeting, sought to examine prevailing trends in VTE thromboprophylaxis in spinal surgery and to compare selections made by Orthopaedic and Neurosurgeons. We developed a questionnaire based around eight clinical scenarios. Participants were asked to supply details on their speciality (orthopaedics or neurosurgery) and level of training (grade) and to select which method(s) of thromboprophylaxis they would employ for each scenario. Thirty-nine participants provided responses to the eight scenarios; complete details, including speciality and grade of those surveyed, were complied for 27 of the 39 questionnaires completed. LMWH was the preferred pharmacological method of thromboprophylaixs selected 31% and 72% of the time by orthopaedic and neurosurgeons respectively. For each of the eight clinical scenarios LMWH and BK TEDS were selected more frequently by neurosurgeons than
Although lumbosacral transitional vertebrae (LSTV) are well-documented, few large-scale studies have investigated thoracolumbar transitional vertebrae (TLTV) and spinal numerical variants. This study sought to establish the prevalence of numerical variants and to evaluate their relationship with clinical problems. A total of 1,179 patients who had undergone thoracic, abdominal, and pelvic CT scanning were divided into groups according to the number of thoracic and lumbar vertebrae, and the presence or absence of TLTV or LSTV. The prevalence of spinal anomalies was noted. The relationship of spinal anomalies to clinical symptoms (low back pain, Japanese Orthopaedic Association score, Roland-Morris Disability Questionnaire) and degenerative spondylolisthesis (DS) was also investigated.Aims

The aim of the present study was to answer the question whether curve morphology and location have an influence on rigid conservative treatment in patients with adolescent idiopathic scoliosis (AIS). We retrospectively analyzed AIS in 127 patients with single and double curves who had been treated with a Chêneau brace and physiotherapeutic specific exercises (B-PSE). The inclusion criteria were the presence of structural major curves ≥ 20° and < 50° (Risser stage 0 to 2) at the time when B-PSE was initiated. The patients were divided into two groups according to the outcome of treatment: failure (curve progression to ≥ 45° or surgery) and success (curve progression < 45° and no surgery). The main curve type (MCT), curve magnitude, and length (overall, above and below the apex), apical rotation, initial curve correction, flexibility, and derotation by the brace were compared between the two groups.Aims
Methods
The aim of this study was to use diffusion tensor imaging (DTI) to investigate changes in diffusion metrics in patients with cervical spondylotic myelopathy (CSM) up to five years after decompressive surgery. We correlated these changes with clinical outcomes as scored by the Modified Japanese Orthopedic Association (mJOA) method, Neck Disability Index (NDI), and Visual Analogue Scale (VAS). We used multi-shot, high-resolution, diffusion tensor imaging (ms-DTI) in patients with cervical spondylotic myelopathy (CSM) to investigate the change in diffusion metrics and clinical outcomes up to five years after anterior cervical interbody discectomy and fusion (ACDF). High signal intensity was identified on T2-weighted imaging, along with DTI metrics such as fractional anisotropy (FA). MJOA, NDI, and VAS scores were also collected and compared at each follow-up point. Spearman correlations identified correspondence between FA and clinical outcome scores.Aims

Competency levels of AOSpine members (Europe) based on whether or not they had undertaken a full 12 month fellowship in spinal surgery. Self-assessment questionnaire distributed to members (60 questions relating to: previous surgical training, fellowships and their nature, and both theoretical and practical competency amongst basic and advanced spinal conditions). 289 completed responses. Competency levels with(out) fellowship; differences in fellowship training; overall competence in spinal surgery as neurosurgeons versus those trained as
We have examined how many and which potential complications (PCs) are recorded on the consent form by a group of consultant surgeons performing common spinal procedures - anterior cervical discectomy and fusion (ACDF) and posterior lumbar discectomy and/or medial facetectomy (PLD). Email survey. Consultant spinal surgeons performing ACDF and/or PLD practicing in Southwest England. Identification of the PCs each surgeon listed on the consent form for the specified procedures. There were 23 responses from 28 Consultant surgeons approached. 21 surgeons performed both ACDF and PLD, 2 performed only PLD. Surgeons quoted 5 to 17 (mode 10) PCs for ACDF and 4 to 15 (mode 13) for PLD. These did not necessarily represent the most common or most dangerous PCs recorded in the literature. 1,2. Small difference in PCs mentioned by Neurosurgeons and
To establish the incidence of litigation in Cauda Equina Syndrome (CES) and the causes of litigation. Review of 10 years of abbreviated records of the National Health Service litigation authority (NHSLA) (1997-2007) and eight years of medical negligence cases (MNC) reported on by the two senior authors (2000-2008). Patients who experienced CES and litigated. There were 117 patients in the NHSLA records and 23 patients in the MNC group. Review of timing of onset, delay in diagnosis, responsible specialist, place, and resulting symptoms. NHSLA cases. 62/117 cases were closed. The responsible specialists were as follows. Orthopaedic. 60. Accident and Emergency. 32. Other. 25. The commonest failure was delay in diagnosis, and the commonest complications were “neurological”, bladder and bowel. MNC cases. F:M;17/6. L4/5 13 cases, L5/S1 9 cases. The responsible specialist was orthopaedic (7), other (7) and in 8 cases the opinion was that there was no case to answer. Delay to treatment averaged 6.14 days. 18/23 patients described bowel and bladder symptoms, the information was not available in the remainder. Litigation is major problem in CES. In most cases
The purpose of this study was to evaluate the incidence and analyze the trends of surgeon-reported complications following surgery for adolescent idiopathic scoliosis (AIS) over a 13-year period from the Scoliosis Research Society (SRS) Morbidity and Mortality database. All patients with AIS between ten and 18 years of age, entered into the SRS Morbidity and Mortality database between 2004 and 2016, were analyzed. All perioperative complications were evaluated for correlations with associated factors. Complication trends were analyzed by comparing the cohorts between 2004 to 2007 and 2013 to 2016.Aims

Introduction. Genetic predisposition is a key causal factor in adolescent idiopathic scoliosis (AIS), which is the most common form of spinal deformity. However, common quantitative genetic effect estimates such as hereditability have not been fully evaluated and reported for this disorder. We aimed to determine the sibling recurrent risk and hereditability of AIS in first-degree relatives of 513 Chinese patients with this disorder. Methods. Family members of 513 Chinese patients with AIS attending a scoliosis clinic were assessed. A diagnosis of AIS was made with the criteria of Cobb angle greater than 20°. The evaluation included clinical assessment and physical examination in a health screening centre by medical doctors with use of forward bending test. Any positive screening cases were referred to a scoliosis clinic for follow-up spinal radiograph. All radiographs were assessed by an
