To systematically evaluate whether bracing can effectively achieve curve regression in patients with adolescent idiopathic scoliosis (AIS), and to identify any predictors of curve regression after bracing. Two independent reviewers performed a comprehensive literature search in PubMed, Ovid, Web of Science, Scopus, and Cochrane Library to obtain all published information about the effectiveness of bracing in achieving curve regression in AIS patients. Search terms included “brace treatment” or “bracing,” “idiopathic scoliosis,” and “curve regression” or “curve reduction.” Inclusion criteria were studies recruiting patients with AIS undergoing brace treatment and one of the study outcomes must be curve regression or reduction, defined as > 5° reduction in coronal Cobb angle of a major curve upon bracing completion. Exclusion criteria were studies including non-AIS patients, studies not reporting p-value or confidence interval, animal studies, case reports, case series, and systematic reviews. The GRADE approach to assessing quality of evidence was used to evaluate each publication.Aims
Methods
The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months.Aims
Methods
To determine whether side-bending films in scoliosis are assessed for adequacy in clinical practice; and to introduce a novel method for doing so. Six surgeons and eight radiographers were invited to participate in four online surveys. The generic survey comprised erect and left and right bending radiographs of eight individuals with scoliosis, with an average age of 14.6 years. Respondents were asked to indicate whether each bending film was optimal (adequate) or suboptimal. In the first survey, they were also asked if they currently assessed the adequacy of bending films. A similar second survey was sent out two weeks later, using the same eight cases but in a different order. In the third survey, a guide for assessing bending film adequacy was attached along with the radiographs to introduce the novel T1-45B method, in which the upper endplate of T1 must tilt ≥ 45° from baseline for the study to be considered optimal. A fourth and final survey was subsequently conducted for confirmation.Aims
Methods
Surgical approaches to cervical ossification of the posterior longitudinal ligament (OPLL) remain controversial. The purpose of the present study was to analyze and compare the long-term neurological recovery following anterior decompression with fusion (ADF) and posterior laminectomy and fusion with bone graft and internal fixation (PLF) based on > ten-year follow-up outcomes in a single centre. Included in this retrospective cohort study were 48 patients (12 females; mean age 55.79 years (SD 8.94)) who were diagnosed with cervical OPLL, received treatment in our centre, and were followed up for 10.22 to 15.25 years. Of them, 24 patients (six females; mean age 52.88 years (SD 8.79)) received ADF, and the other 24 patients (five females; mean age 56.25 years (SD 9.44)) received PLF. Clinical data including age, sex, and the OPLL canal-occupying ratio were analyzed and compared. The primary outcome was Japanese Orthopaedic Association (JOA) score, and the secondary outcome was visual analogue scale neck pain.Aims
Methods
The aim of this study was to investigate the impact of the level of upper instrumented vertebra (UIV) in frail patients undergoing surgery for adult spine deformity (ASD). Patients with adult spinal deformity who had undergone T9-to-pelvis fusion were stratified using the ASD-Modified Frailty Index into not frail, frail, and severely frail categories. ASD was defined as at least one of: scoliosis ≥ 20°, sagittal vertical axis (SVA) ≥ 5 cm, or pelvic tilt ≥ 25°. Means comparisons tests were used to assess differences between both groups. Logistic regression analyses were used to analyze associations between frailty categories, UIV, and outcomes.Aims
Methods
This systematic review aims to identify 3D predictors derived from biplanar reconstruction, and to describe current methods for improving curve prediction in patients with mild adolescent idiopathic scoliosis. A comprehensive search was conducted by three independent investigators on MEDLINE, PubMed, Web of Science, and Cochrane Library. Search terms included “adolescent idiopathic scoliosis”,“3D”, and “progression”. The inclusion and exclusion criteria were carefully defined to include clinical studies. Risk of bias was assessed with the Quality in Prognostic Studies tool (QUIPS) and Appraisal tool for Cross-Sectional Studies (AXIS), and level of evidence for each predictor was rated with the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. In all, 915 publications were identified, with 377 articles subjected to full-text screening; overall, 31 articles were included.Aims
Methods
This study aimed to evaluate rasterstereography of the spine as a diagnostic test for adolescent idiopathic soliosis (AIS), and to compare its results with those obtained using a scoliometer. Adolescents suspected of AIS and scheduled for radiographs were included. Rasterstereographic scoliosis angle (SA), maximal vertebral surface rotation (ROT), and angle of trunk rotation (ATR) with a scoliometer were evaluated. The area under the curve (AUC) from receiver operating characteristic (ROC) plots were used to describe the discriminative ability of the SA, ROT, and ATR for scoliosis, defined as a Cobb angle > 10°. Test characteristics (sensitivity and specificity) were reported for the best threshold identified using the Youden method. AUC of SA, ATR, and ROT were compared using the bootstrap test for two correlated ROC curves method.Aims
Methods
To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation. A retrospective study was conducted using prospectively collected data and patient-reported outcome measures, including the Oswestry Disability Index (ODI), between 2008 and 2019. Postoperative sRDH was identified from clinical notes and the centre’s MRI database, with all imaging providers in the region checked for missing events. The Kaplan-Meier method was used to calculate five-year sRDH incidence. Cox proportional hazards model was used to identify independent variables predictive of sRDH, with any variable not significant at the p < 0.1 level removed. Hazard ratios (HRs) were calculated with 95% confidence intervals (CIs).Aims
Methods
Gram-negative infections are associated with comorbid patients, but outcomes are less well understood. This study reviewed diagnosis, management, and treatment for a cohort treated in a tertiary spinal centre. A retrospective review was performed of all gram-negative spinal infections (n = 32; median age 71 years; interquartile range 60 to 78), excluding surgical site infections, at a single centre between 2015 to 2020 with two- to six-year follow-up. Information regarding organism identification, antibiotic regime, and treatment outcomes (including clinical, radiological, and biochemical) were collected from clinical notes.Aims
Methods
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
Methods
Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age. Patients aged ≥ 18 years with a traumatic CCS between January 2012 and December 2017 in Wales were identified. Patient demographics and data about injury, management, and outcome were collected. Statistical analysis was performed to assess mortality and between-group differences.Aims
Methods
Psychoeducative prehabilitation to optimize surgical outcomes is relatively novel in spinal fusion surgery and, like most rehabilitation treatments, they are rarely well specified. Spinal fusion patients experience anxieties perioperatively about pain and immobility, which might prolong hospital length of stay (LOS). The aim of this prospective cohort study was to determine if a Preoperative Spinal Education (POSE) programme, specified using the Rehabilitation Treatment Specification System (RTSS) and designed to normalize expectations and reduce anxieties, was safe and reduced LOS. POSE was offered to 150 prospective patients over ten months (December 2018 to November 2019) Some chose to attend (Attend-POSE) and some did not attend (DNA-POSE). A third independent retrospective group of 150 patients (mean age 57.9 years (SD 14.8), 50.6% female) received surgery prior to POSE (pre-POSE). POSE consisted of an in-person 60-minute education with accompanying literature, specified using the RTSS as psychoeducative treatment components designed to optimize cognitive/affective representations of thoughts/feelings, and normalize anxieties about surgery and its aftermath. Across-group age, sex, median LOS, perioperative complications, and readmission rates were assessed using appropriate statistical tests.Aims
Methods
To determine the value of scoliosis surgery, it is necessary to evaluate outcomes in domains that matter to patients. Since randomized trials on adolescent idiopathic scoliosis (AIS) are scarce, prospective cohort studies with comparable outcome measures are important. To enhance comparison, a core set of patient-related outcome measures is available. The aim of this study was to evaluate the outcomes of AIS fusion surgery at two-year follow-up using the core outcomes set. AIS patients were systematically enrolled in an institutional registry. In all, 144 AIS patients aged ≤ 25 years undergoing primary surgery (median age 15 years (interquartile range 14 to 17) were included. Patient-reported (condition-specific and health-related quality of life (QoL); functional status; back and leg pain intensity) and clinician-reported outcomes (complications, revision surgery) were recorded. Changes in patient-reported outcome measures (PROMs) were analyzed using Friedman’s analysis of variance. Clinical relevancy was determined using minimally important changes (Scoliosis Research Society (SRS)-22r), cut-off values for relevant effect on functioning (pain scores) and a patient-acceptable symptom state (PASS; Oswestry Disability Index).Aims
Methods
To develop and internally validate a preoperative clinical prediction model for acute adjacent vertebral fracture (AVF) after vertebral augmentation to support preoperative decision-making, named the after vertebral augmentation (AVA) score. In this prognostic study, a multicentre, retrospective single-level vertebral augmentation cohort of 377 patients from six Japanese hospitals was used to derive an AVF prediction model. Backward stepwise selection (p < 0.05) was used to select preoperative clinical and imaging predictors for acute AVF after vertebral augmentation for up to one month, from 14 predictors. We assigned a score to each selected variable based on the regression coefficient and developed the AVA scoring system. We evaluated sensitivity and specificity for each cut-off, area under the curve (AUC), and calibration as diagnostic performance. Internal validation was conducted using bootstrapping to correct the optimism.Aims
Methods
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.
Cauda equina syndrome (CES) can be associated with chronic severe lower back pain and long-term autonomic dysfunction. This study assesses the recently defined core outcome set for CES in a cohort of patients using validated questionnaires. Between January 2005 and December 2019, 82 patients underwent surgical decompression for acute CES secondary to massive lumbar disc prolapse at our hospital. After review of their records, patients were included if they presented with the clinical and radiological features of CES, then classified as CES incomplete (CESI) or with painless urinary retention (CESR) in accordance with guidelines published by the British Association of Spinal Surgeons. Patients provided written consent and completed a series of questionnaires.Aims

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
Minimal clinically important differences (MCID)
in the scores of patient-reported outcome measures allow clinicians to
assess the outcome of intervention from the perspective of the patient.
There has been significant variation in their absolute values in
previous publications and a lack of consistency in their calculation. The purpose of this study was first, to establish whether these
values, following spinal surgery, vary depending on the surgical
intervention and their method of calculation and secondly, to assess
whether there is any correlation between the two external anchors
most frequently used to calculate the MCID. . We carried out a retrospective analysis of prospectively gathered
data of adult patients who underwent elective spinal surgery between
1994 and 2009. A total of 244 patients were included. There were
125 men and 119 women with a mean age of 54 years (16 to 84); the
mean follow-up was 62 months (6 to 199) The MCID was calculated
using three previously published methods. Our results show that the value of the MCID varies considerably
with the operation and its method of calculation. There was good
correlation between the two external anchors. The global outcome
tool correlated significantly better. We conclude that
To report the outcome of spinal deformity correction through anterior spinal fusion in wheelchair-bound patients with myelomeningocele. We reviewed 12 consecutive patients (7M:5F; mean age 12.4 years (9.2 to 16.8)) including demographic details, spinopelvic parameters, surgical correction, and perioperative data. We assessed the impact of surgery on patient outcomes using the Spina Bifida Spine Questionnaire and a qualitative questionnaire.Aims
Methods
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
To benchmark the radiation dose to patients during the course of treatment for a spinal deformity. Our radiation dose database identified 25,745 exposures of 6,017 children (under 18 years of age) and adults treated for a spinal deformity between 1 January 2008 and 31 December 2016. Patients were divided into surgical (974 patients) and non-surgical (5,043 patients) cohorts. We documented the number and doses of ionizing radiation imaging events (radiographs, CT scans, or intraoperative fluoroscopy) for each patient. All the doses for plain radiographs, CT scans, and intraoperative fluoroscopy were combined into a single effective dose by a medical physicist (milliSivert (mSv)).Aims

The aim of this study was to determine the differences in spinal imaging characteristics between subjects with or without lumbar developmental spinal stenosis (DSS) in a population-based cohort. This was a radiological analysis of 2,387 participants who underwent L1-S1 MRI. Means and ranges were calculated for age, sex, BMI, and MRI measurements. Anteroposterior (AP) vertebral canal diameters were used to differentiate those with DSS from controls. Other imaging parameters included vertebral body dimensions, spinal canal dimensions, disc degeneration scores, and facet joint orientation. Mann-Whitney U and chi-squared tests were conducted to search for measurement differences between those with DSS and controls. In order to identify possible associations between DSS and MRI parameters, those who were statistically significant in the univariate binary logistic regression were included in a multivariate stepwise logistic regression after adjusting for demographics. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported where appropriate.Aims

Whether a combined anteroposterior fusion or a posterior-only fusion is more effective in the management of patients with Scheuermann’s kyphosis remains controversial. The aim of this study was to compare the radiological and clinical outcomes of these surgical approaches, and to evaluate the postoperative complications with the hypothesis that proximal junctional kyphosis would be more common in one-stage posterior-only fusion. A retrospective review of patients treated surgically for Scheuermann’s kyphosis between 2006 and 2014 was performed. A total of 62 patients were identified, with 31 in each group. Parameters were compared to evaluate postoperative outcomes using chi-squared tests, independent-samples Aims

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
Methods
It is uncertain whether instrumented spinal fixation in nonambulatory children with neuromuscular scoliosis should finish at L5 or be extended to the pelvis. Pelvic fixation has been shown to be associated with up to 30% complication rates, but is regarded by some as the standard for correction of deformity in these conditions. The incidence of failure when comparing the most caudal level of instrumentation, either L5 or the pelvis, using all-pedicle screw instrumentation has not previously been reported. In this retrospective study, we compared nonambulatory patients undergoing surgery at two centres: one that routinely instrumented to L5 and the other to the pelvis. In all, 91 nonambulatory patients with neuromuscular scoliosis were included. All underwent surgery using bilateral, segmental, pedicle screw instrumentation. A total of 40 patients underwent fusion to L5 and 51 had their fixation extended to the pelvis. The two groups were assessed for differences in terms of clinical and radiological findings, as well as complications.Aims
Methods
Significant correction of an adolescent idiopathic scoliosis in the coronal plane through a posterior approach is associated with hypokyphosis. Factors such as the magnitude of the preoperative coronal curve, the use of hooks, number of levels fused, preoperative kyphosis, screw density, and rod type have all been implicated. Maintaining the normal thoracic kyphosis is important as hypokyphosis is associated with proximal junctional failure (PJF) and early onset degeneration of the spine. The aim of this study was to determine if coronal correction per se was the most relevant factor in generating hypokyphosis. A total of 95 patients (87% female) with a median age of 14 years were included in our study. Pre- and postoperative radiographs were measured and the operative data including upper instrumented vertebra (UIV), lower instrumented vertebra (LIV), metal density, and thoracic flexibility noted. Further analysis of the post-surgical coronal outcome (group 1 < 60% correction and group 2 ≥ 60%) were studied for their association with the postoperative kyphosis in the sagittal plane using univariate and multivariate logistic regression.Aims
Methods
This study aimed to evaluate the incidence and prognosis of patients with spinal metastasis as the initial manifestation of malignancy (SM-IMM). We retrospectively reviewed the electronic medical records of 338 patients who underwent surgical treatment for metastatic spinal disease. The enrolled patients were divided into two groups. The SM-IMM group included patients with no history of malignancy whose site of primary malignancy was diagnosed after the identification of spinal metastasis. The other group included patients with a history of treatment for primary malignancy who then developed spinal metastasis (SM-DTM). The incidence of SM-IMM by site of primary malignancy was calculated. The difference between prognoses after surgical treatment for SM-IMM and SM-DTM was established.Aims
Patients and Methods
The aim of this study was to determine the influence of pelvic parameters on the tendency of patients with adolescent idiopathic scoliosis (AIS) to develop flatback deformity (thoracic hypokyphosis and lumbar hypolordosis) and its effect on quality-of-life outcomes. This was a radiological study of 265 patients recruited for Boston bracing between December 2008 and December 2013. Posteroanterior and lateral radiographs were obtained before, immediately after, and two-years after completion of bracing. Measurements of coronal and sagittal Cobb angles, coronal balance, sagittal vertical axis, and pelvic parameters were made. The refined 22-item Scoliosis Research Society (SRS-22r) questionnaire was recorded. Association between independent factors and outcomes of postbracing ≥ 6° kyphotic changes in the thoracic spine and ≥ 6° lordotic changes in the lumbar spine were tested using likelihood ratio chi-squared test and univariable logistic regression. Multivariable logistic regression models were then generated for both outcomes with odds ratios (ORs), and with SRS-22r scores.Aims
Patients and 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

The purpose of this retrospective study was to investigate the
clinical relevance of increased facet joint distraction as a result
of anterior cervical decompression and fusion (ACDF) for trauma. A total of 155 patients (130 men, 25 women. Mean age 42.7 years;
16 to 87) who had undergone ACDF between 1 January 2001 and 1 January
2016 were included in the study. Outcome measures included the Neck
Disability Index (NDI) and visual analogue scale (VAS) for pain.
Lateral cervical spine radiographs taken in the immediate postoperative
period were reviewed to compare the interfacet distance of the operated
segment with those of the facet joints above and below.Aims
Patients and Methods
Magnetically controlled growing rods (MCGRs) allow non-invasive
correction of the spinal deformity in the treatment of early-onset
scoliosis. Conventional growing rod systems (CGRS) need repeated
surgical distractions: these are associated with the effect of the
‘law of diminishing returns’. The primary aim of this study was to quantify this effect in
MCGRs over sequential distractions. A total of 35 patients with a maximum follow-up of 57 months
were included in the study. There were 17 boys and 18 girls with
a mean age of 7.4 years (2 to 14). True Distraction (TD) was determined
by measuring the expansion gap on fluoroscopy. This was compared
with Intended Distraction (ID) and expressed as the ‘T/I’ ratio.
The T/I ratio and the Cobb angle were calculated at several time
points during follow-up.Aims
Patients and Methods
There is little information about the optimum number of implants
to be used in the surgical treatment of idiopathic scoliosis. Retrospective
analysis of prospectively collected data from the Swedish spine
register was undertaken to discover whether more implants per operated
vertebra (implant density) leads to a better outcome in the treatment of
idiopathic scoliosis. The hypothesis was that implant density is
not associated with patient-reported outcomes, the correction of
the curve or the rate of reoperation. A total of 328 patients with idiopathic scoliosis, aged between
ten and 20 years at the time of surgery, were identified in the
Swedish spine register (Swespine) and had patient reported outcomes
including the Scoliosis Research Society 22r instrument (SRS-22r)
score, EuroQol 5 dimensions quality of life, 3 level (EQ-5D-3L)
score and a Viual Analogue Score (VAS) for back pain, at a mean
follow-up of 3.1 years and reoperation data at a mean follow-up
of 5.5 years. Implant data and the correction of the curve were
assessed from radiographs, preoperatively and a mean of 1.9 years
postoperatively. The patients were divided into tertiles based on
implant density. Data were analyzed with analysis of variance, logistic
regression or log-rank test. Some analyses were adjusted for gender,
age at the time of surgery, the flexibility of the major curve and
follow-up.Aims

The aim of this study was to evaluate improvements in the quality
and safety of paediatric spinal surgery following the implementation
of a specialist Paediatric Spinal Surgical Team (PSST) in the operating
theatre. A retrospective consecutive case study of paediatric spinal operations
before (between January 2008 and December 2009), and after (between
January 2012 and December 2013) the implementation of PSST, was
performed. A comparative analysis of outcome variables including
surgical site infection (SSI), operating time (ORT), blood loss (BL),
length of stay (LOS), unplanned staged procedures (USP) and transfusion
rates (allogenic and cell-saver) was performed between the two groups.
The rate of complications during the first two postoperative years
was also compared between the groups.Aims

We compared the clinical and radiological outcomes of using a
polyetheretherketone cage with (TiPEEK) and without a titanium coating
(PEEK) for instrumented transforaminal lumbar interbody fusion (TLIF). We conducted a randomised clinical pilot trial of 40 patients
who were scheduled to undergo a TLIF procedure at one or two levels
between L2 and L5. The Oswestry disability index (ODI), EuroQoL-5D,
and back and leg pain were determined pre-operatively, and at three,
six, and 12 months post-operatively. Fusion rates were assessed
by thin slice CT at three months and by functional radiography at
12 months.Aims
Materials and Methods
We aimed to retrospectively assess the accuracy and safety of
CT navigated pedicle screws and to compare accuracy in the cervical
and thoracic spine (C2-T8) with (COMB) and without (POST) prior
anterior surgery (anterior cervical discectomy or corpectomy and
fusion with ventral plating: ACDF/ACCF). A total of 592 pedicle screws, which were used in 107 consecutively
operated patients (210 COMB, 382 POST), were analysed. The accuracy
of positioning was determined according to the classification of
Gertzbein and Robbins on post-operative CT scans.Aims

To evaluate the incidence of primary venous thromboembolism (VTE),
epidural haematoma, surgical site infection (SSI), and 90-day mortality
after elective spinal surgery, and the effect of two protocols for
prophylaxis. A total of 2181 adults underwent 2366 elective spinal procedures
between January 2007 and January 2012. All patients wore anti-embolic
stockings, mobilised early and were kept adequately hydrated. In
addition, 29% (689) of these were given low molecular weight heparin
(LMWH) while in hospital. SSI surveillance was undertaken using the
Centers for Disease Control and Prevention criteria.Aims

Our aim was to perform a systematic review of the literature
to assess the incidence of post-operative epidural haematomas and
wound infections after one-, or two-level, non-complex, lumbar surgery

wound drainage. Studies were identified from PubMed and EMBASE, up to and including
27 August 2015, for papers describing one- or two-level lumbar discectomy
and/or laminectomy for degenerative disease in adults which reported
any form of subcutaneous or subfascial drainage.Aims

Identifying cervical spine injuries in confused or comatose patients
with multiple injuries provides a diagnostic challenge. Our aim
was to investigate the protocols which are used for the clearance
of the cervical spine in these patients in English hospitals. All hospitals in England with an Emergency Department were asked

All 22 Major Trauma Centres (MTCs) and 141 of 156 non-MTCs responded
(response rate 91.5%).Aim
Patients and Methods
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 total of 30 patients with thoracolumbar/lumbar adolescent idiopathic
scoliosis (AIS) treated between 1989 and 2000 with anterior correction
and fusion surgery using dual-rod instrumentation were reviewed. Radiographic parameters and clinical outcomes were compared among
patients with lowest instrumented vertebra (LIV) at the lower end
vertebra (LEV; EV group) (n = 13) and those treated by short fusion
(S group), with LIV one level proximal to EV (n = 17 patients). Aims
Patients and Methods
We assessed the frequency and causes of neurological
deterioration in 59 patients with spinal cord injury on whom reports
were prepared for clinical negligence litigation. In those who deteriorated
neurologically we assessed the causes of the change in neurology
and whether that neurological deterioration was potentially preventable.
In all 27 patients (46%) changed neurologically, 20 patients (74%
of those who deteriorated) had no primary neurological deficit.
Of those who deteriorated, 13 (48%) became Frankel A. Neurological
deterioration occurred in 23 of 38 patients (61%) with unstable
fractures and/or dislocations; all 23 patients probably deteriorated
either because of failures to immobilise the spine or because of
inappropriate removal of spinal immobilisation. Of the 27 patients who
altered neurologically, neurological deterioration was, probably,
avoidable in 25 (excess movement in 23 patients with unstable injuries,
failure to evacuate an epidural haematoma in one patient and over-distraction following
manipulation of the cervical spine in one patient). If existing
guidelines and standards for the management of actual or potential
spinal cord injury had been followed, neurological deterioration
would have been prevented in 25 of the 27 patients (93%) who experienced
a deterioration in their neurological status. Cite this article:

non-operatively or operatively in our institution. In all 16 patients were included (eight female: eight male; 50%
male), of whom nine had Hurler, five Morquio and two Hunter syndrome.
Six patients were treated non-operatively (mean age at presentation
of 6.3 years; 0.4 to 12.9); mean kyphotic progression +1.5o/year;
mean follow-up of 3.1 years (1 to 5.1) and ten patients operatively (mean
age at presentation of 4.7 years; 0.9 to 14.4); mean kyphotic progression
10.8o/year; mean follow-up of 8.2 years; 4.8 to 11.8)
by circumferential arthrodesis with posterior instrumentation in
patients with flexible deformities (n = 6).Aims
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
Methods
Lumbar disc herniation (LDH) is uncommon in youth
and few cases are treated surgically. Very few outcome studies exist
for LDH surgery in this age group. Our aim was to explore differences
in gender in pre-operative level of disability and outcome of surgery
for LDH in patients aged ≤ 20 years using prospectively collected
data. From the national Swedish SweSpine register we identified 180
patients with one-year and 108 with two-year follow-up data ≤ 20
years of age, who between the years 2000 and 2010 had a primary
operation for LDH. Both male and female patients reported pronounced impairment
before the operation in all patient reported outcome measures, with
female patients experiencing significantly greater back pain, having
greater analgesic requirements and reporting significantly inferior
scores in EuroQol (EQ-5D-index), EQ-visual analogue scale, most aspects
of Short Form-36 and Oswestry Disabilities Index, when compared
with male patients. Surgery conferred a statistically significant
improvement in all registered parameters, with few gender discrepancies.
Quality of life at one year following surgery normalised in both
males and females and only eight patients (4.5%) were dissatisfied with
the outcome. Virtually all parameters were stable between the one-
and two-year follow-up examination. LDH surgery leads to normal health and a favourable outcome in
both male and female patients aged 20 years or younger, who failed
to recover after non-operative management. Cite this article:
The aim of this study was to determine whether
obesity affects pain, surgical and functional outcomes following lumbar
spinal fusion for low back pain (LBP). A systematic literature review and meta-analysis was made of
those studies that compared the outcome of lumbar spinal fusion
for LBP in obese and non-obese patients. A total of 17 studies were
included in the meta-analysis. There was no difference in the pain
and functional outcomes. Lumbar spinal fusion in the obese patient resulted
in a statistically significantly greater intra-operative blood loss
(weighted mean difference: 54.04 ml; 95% confidence interval (CI)
15.08 to 93.00; n = 112; p = 0.007) more complications (odds ratio:
1.91; 95% CI 1.68 to 2.18; n = 43858; p <
0.001) and longer duration
of surgery (25.75 mins; 95% CI 15.61 to 35.90; n = 258; p <
0.001). Obese
patients have greater intra-operative blood loss, more complications
and longer duration of surgery but pain and functional outcome are
similar to non-obese patients. Based on these results, obesity is
not a contraindication to lumbar spinal fusion. Cite this article:
Acute angulation at the thoracolumbar junction
with segmental subluxation of the spine occurring at the level above
an anteriorly hypoplastic vertebra in otherwise normal children
is a rare condition described as infantile developmental thoracolumbar
kyphosis. Three patient series with total of 18 children have been
reported in the literature. We report five children who presented
with thoracolumbar kyphosis and discuss the treatment algorithm. We
reviewed the medical records and spinal imaging at initial clinical
presentation and at minimum two-year follow-up. The mean age at
presentation was eight months (two to 12). All five children had
L2 anterior vertebral body hypoplasia. The kyphosis improved spontaneously
in three children kept under monitoring. In contrast, the deformity
was progressive in two patients who were treated with bracing. The
kyphosis and segmental subluxation corrected at latest follow-up
(mean age 52 months; 48 to 60) in all patients with near complete
reconstitution of the anomalous vertebra. The deformity and radiological
imaging on a young child can cause anxiety to both parents and treating
physicians. Diagnostic workup and treatment algorithm in the management
of infantile developmental thoracolumbar kyphosis is proposed. Observation
is indicated for non-progressive kyphosis and bracing if there is evidence
of kyphosis and segmental subluxation deterioration beyond walking
age. Surgical stabilisation of the spine can be reserved for severe
progressive deformities unresponsive to conservative treatment. Cite this article:
This short contribution aims to explain how intervertebral disc ‘degeneration’ differs from normal ageing, and to suggest how mechanical loading and constitutional factors interact to cause disc degeneration and prolapse. We suggest that disagreement on these matters in medico-legal practice often arises from a misunderstanding of the nature of ‘soft-tissue injuries’.
Clinical, radiological, and Scoliosis Research
Society-22 questionnaire data were reviewed pre-operatively and
two years post-operatively for patients with thoracolumbar/lumbar
adolescent idiopathic scoliosis treated by posterior spinal fusion
using a unilateral convex segmental pedicle screw technique. A total
of 72 patients were included (67 female, 5 male; mean age at surgery
16.7 years (13 to 23)) and divided into groups: group 1 included
53 patients who underwent fusion between the vertebrae at the limit
of the curve (proximal and distal end vertebrae); group 2 included
19 patients who underwent extension of the fusion distally beyond
the caudal end vertebra. A mean scoliosis correction of 80% (45% to 100%) was achieved.
The mean post-operative lowest instrumented vertebra angle, apical
vertebra translation and trunk shift were less than in previous
studies. A total of five pre-operative radiological parameters differed
significantly between the groups and correlated with the extension
of the fusion distally: the size of the thoracolumbar/lumbar curve,
the lowest instrumented vertebra angle, apical vertebra translation,
the Cobb angle on lumbar convex bending and the size of the compensatory
thoracic curve. Regression analysis allowed an equation incorporating
these parameters to be developed which had a positive predictive
value of 81% in determining whether the lowest instrumented vertebra
should be at the caudal end vertebra or one or two levels more distal.
There were no differences in the Scoliosis Research Society-22 outcome
scores between the two groups (p = 0.17). In conclusion, thoracolumbar/lumbar curves in patients with adolescent
idiopathic scoliosis may be effectively treated by posterior spinal
fusion using a unilateral segmental pedicle screw technique. Five
radiological parameters correlate with the need for distal extension
of the fusion, and an equation incorporating these parameters reliably
informs selection of the lowest instrumented vertebra. Cite this article:
