Guidelines recommend epidural steroid injections (ESI) for treating severe disc-related sciatica based on trial data showing modest reductions in leg pain, disability and surgery avoidance. Despite their widespread use, there is no clear evidence about which patients are more likely to benefit from ESI. The aim of this study was to generate consensus on potential predictors of outcome following ESI for disc-related sciatica to include in data collection in a future cohort study. A list of potential predictors of outcome following ESI was generated from existing literature and a consensus meeting with seven experts. Items were subsequently presented in a two-round on-line modified Delphi study to generate consensus among experts on which items are agreed as potential predictors of outcome from ESI (consensus defined as 70% agreement with ranking of remaining items).Background
Methods
Historically, patients undergoing surgery for adolescent idiopathic scoliosis (AIS) have been nursed postoperatively in a critical care (CC) setting because of the challenges posed by prone positioning, extensive exposures, prolonged operating times, significant blood loss, major intraoperative fluid shifts, cardiopulmonary complications, and difficulty in postoperative pain management. The primary aim of this paper was to determine whether a scoring system, which uses Cobb angle, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and number of levels to be fused, is a valid method of predicting the need for postoperative critical care in AIS patients who are to undergo scoliosis correction with posterior spinal fusion (PSF). We retrospectively reviewed all AIS patients who had undergone PSF between January 2018 and January 2020 in a specialist tertiary spinal referral centre. All patients were assessed preoperatively in an anaesthetic clinic. Postoperative care was defined as ward-based (WB) or critical care (CC)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
Methods
Fracture of the odontoid process (OP) in the elderly is associated with mortality rates similar to those of hip fracture. The aim of this study was to identify variables that predict mortality in patients with a fracture of the OP, and to assess whether established hip fracture scoring systems such as the Nottingham Hip Fracture Score (NHFS) or Sernbo Score might also be used as predictors of mortality in these patients. We conducted a retrospective review of patients aged 65 and over with an acute fracture of the OP from two hospitals. Data collected included demographics, medical history, residence, mobility status, admission blood tests, abbreviated mental test score, presence of other injuries, and head injury. All patients were treated in a semi-rigid cervical orthosis. Univariate and multivariate analysis were undertaken to identify predictors of mortality at 30 days and one year. A total of 82 patients were identified. There were 32 men and 50 women with a mean age of 83.7 years (67 to 100).Aims
Patients and Methods
Acute and chronic spinal pain are major causes of disability, and many patients use analgesics to treat their pain. However, increased use of analgesics, particularly prescription opioids have the potential to be overused and cause dependence. Psychological factors such as stress, anxiety, depression, pain acceptance, pain catastrophising and alexithymia influence both the pain response and analgesic use, yet to date no studies have explored these variables in spinal pain patients. Therefore, the aim of this study is to assess the nature, prevalence and correlates of analgesic dependence among patients with acute or chronic spinal pain. Patients over the age of 18 attending outpatient services at the Royal Derby Hospital with complaints of either acute or chronic spinal pain and currently using analgesics to treat their pain completed the Current Opioid Misuse Measure, the Depression, Anxiety and Stress Scale-21, the Chronic Pain Acceptance Questionnaire-8, the Pain Catastrophising Scale, the Toronto Alexithymia Scale-20, and the Leeds Dependence Questionnaire, a measure of analgesic dependence. Preliminary findings from 52 patients (16 males and 36 females) with chronic spinal pain ranging from 23–88 years old, show that greater pain catastrophising is a significant predictor of analgesic dependence (Purpose and background
Methods and results
Rates of mortality as high as 25% to 30% have been described
following fractures of the odontoid in the elderly population. The
aim of this study was to examine whether easily identifiable variables
present on admission are associated with mortality. A consecutive series of 83 elderly patients with a fracture of
the odontoid following a low-impact injury was identified retrospectively.
Data that were collected included demographics, past medical history
and the results of blood tests on admission. Radiological investigations
were used to assess the Anderson and D’Alonzo classification and
displacement of the fracture. The mean age was 82.9 years (65 to
101). Most patients (66; 79.5%) had a type 2 fracture. An associated
neurological deficit was present in 11 (13.3%). All were treated
conservatively; 80 (96.4%) with a hard collar and three (3.6%) with
halo vest immobilisation.Aims
Patients and Methods
Low back pain (LBP) is a major health challenge globally. Research has identified common trajectories of pain over time. We aimed to investigate whether trajectories described in one primary care cohort can be confirmed in another, and to determine the prognostic value of factors collected 5 years prior to the identification of the trajectory. The study was carried out on 281 patients who had consulted primary care for LBP, at that point completed a baseline questionnaire, and then returned a questionnaire at 5-years follow-up plus at least 3 (of 6) subsequent monthly questionnaires. Baseline factors were measured using validated tools. Pain intensity scores from the 5-year follow-up and monthly questionnaires were used to cluster participants into 4 previously derived pain trajectories (no or occasional mild, persistent mild, fluctuating, persistent severe), using latent class analysis. Posterior probabilities of belonging to each cluster were estimated for each participant. The posterior probabilities for the assigned clusters were very high (>0.90) for each cluster except for the smallest ‘fluctuating’ cluster (0.74). Lower social class (OR 2.9; 95% CI 1.2, 7.0), higher pain intensity (1.6 per unit; 1.2, 2.2), and pain duration greater than 3 years (2.7; 1.0, 7.3), were significantly associated with a more severe trajectory 5-years later, as were higher physical disability, emotional impact of pain, and perception pain will last a long time.Background and objectives
Methods and results
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
We investigated the pre-operative and one-year post-operative health-related quality of life (HRQOL) outcome by using a Euroqol (EQ-5D) questionnaire in 263 patients who had undergone surgery for herniation of a lumbar disc. Data from the National Swedish Register for lumbar spinal surgery between 2001 and 2002 were used and, in addition, a comparison between our cohort and a Swedish EQ-5D population survey was performed. We analysed the pre- and post-operative quality of life data, age, gender, smoking habits, pain and walking capacity. The mean age of the patients was 42 years (20 to 66); 155 (59%) were men and 69 (26%) smoked. Pre-operatively, 72 (17%) could walk at least 1 km compared with 200 (76%) postoperatively. The mean EQ-5D score improved from 0.29 to 0.70, and the HRQOL improved in 195 (74%) of the patients. The pre-operative score did not influence the post-operative score. In most patients, all five EQ-5D dimensions improved, but did not reach the level reported by an age- and gender-matched population sample (mean difference 0.17).
Aim:. To determine if patients with coronal plane deformity in the lumbar spine have a higher grade of lumbar spine subtype compared to controls. Method:. This was a retrospective case/control study based on a review of radiological investigations in 250 patients aged over 40 years who had standing plain film lumbar radiographs with hips present. Measurements of lumbar coronal plane angle, lumbar lordosis, sacral slope, pelvic tilt and pelvic incidence were obtained. “Cases” with degenerative scoliosis (n=125) were defined as patients with a lumbar coronal plane angle of >10°. Lumbar spine subtype was categorised (1–4) using the Roussouly classification. Lumbar spine subtype was dichotomised into low (type 1,2) or high (type 3,4). Prevalence of lumbar spine subtype in cases versus controls was compared using the Chi squared test. Pelvic incidence was compared using an unpaired T-test.
The aim of this study was to assess the ability of morphological spinal parameters to predict the outcome of bracing in patients with adolescent idiopathic scoliosis (AIS) and to establish a novel supine correction index (SCI) for guiding bracing treatment. Patients with AIS to be treated by bracing were prospectively recruited between December 2016 and 2018, and were followed until brace removal. In all, 207 patients with a mean age at recruitment of 12.8 years (SD 1.2) were enrolled. Cobb angles, supine flexibility, and the rate of in-brace correction were measured and used to predict curve progression at the end of follow-up. The SCI was defined as the ratio between correction rate and flexibility. Receiver operating characteristic (ROC) curve analysis was carried out to assess the optimal thresholds for flexibility, correction rate, and SCI in predicting a higher risk of progression, defined by a change in Cobb angle of ≥ 5° or the need for surgery.Aims
Methods
To report the surgical outcome of patients with severe Scheuermann’s kyphosis treated using a consistent technique and perioperative management. We reviewed 88 consecutive patients with a severe Scheuermann's kyphosis who had undergone posterior spinal fusion with closing wedge osteotomies and hybrid instrumentation. There were 55 males and 33 females with a mean age of 15.9 years (12.0 to 24.7) at the time of surgery. We recorded their demographics, spinopelvic parameters, surgical correction, and perioperative data, and assessed the impact of surgical complications on outcome using the Scoliosis Research Society (SRS)-22 questionnaire.Aims
Methods
In a multicentre, randomised study of adolescents undergoing
posterior spinal fusion for idiopathic scoliosis, we investigated
the effect of adding gelatine matrix with human thrombin to the
standard surgical methods of controlling blood loss. Patients in the intervention group (n = 30) were randomised to
receive a minimum of two and a maximum of four units of gelatine
matrix with thrombin in addition to conventional surgical methods
of achieving haemostasis. Only conventional surgical methods were
used in the control group (n = 30). We measured the intra-operative
and total blood loss (intra-operative blood loss plus post-operative
drain output).Aims
Patients and Methods
This review of the literature presents the current understanding of Scheuermann’s kyphosis and investigates the controversies concerning conservative and surgical treatment. There is considerable debate regarding the pathogenesis, natural history and treatment of this condition. A benign prognosis with settling of symptoms and stabilisation of the deformity at skeletal maturity is expected in most patients. Observation and programmes of exercise are appropriate for mild, flexible, non-progressive deformities. Bracing is indicated for a moderate deformity which spans several levels and retains flexibility in motivated patients who have significant remaining spinal growth. The loss of some correction after the completion of bracing with recurrent anterior vertebral wedging has been reported in approximately one-third of patients. Surgical correction with instrumented spinal fusion is indicated for a severe kyphosis which carries a risk of progression beyond the end of growth causing cosmetic deformity, back pain and neurological complications. There is no consensus on the effectiveness of different techniques and types of instrumentation. Techniques include posterior-only and combined anteroposterior spinal fusion with or without posterior osteotomies across the apex of the deformity. Current instrumented techniques include hybrid and all-pedicle screw constructs.
