Closed suction subfascial drainage is widely used after instrumented posterior spinal fusion in patients with a spinal deformity. The aim of this study was to determine the effect of this wound drainage on the outcomes in patients with adolescent idiopathic scoliosis (AIS). This was a further analysis of a randomized, multicentre clinical trial reporting on patients after posterior spinal fusion using segmental pedicle screw instrumentation. In this study the incidence of deep surgical site infection (SSI) and chronic postoperative pain at two years’ follow-up are reported. We conducted a randomized, multicentre clinical trial on adolescents undergoing posterior spinal fusion for AIS using segmental pedicle screw instrumentation. A total of 90 consecutive patients were randomized into a ‘drain’ or ‘no drain’ group at the time of wound closure, using the sealed envelope technique (1:1). The primary outcomes in the initial study were the change in the level of haemoglobin in the blood postoperatively and total blood loss. A secondary outcome was the opioid consumption immediately after surgery. The aim of this further study was to report the rate of deep SSI and persistent postoperative pain, at two years' follow-up.Aims

Aims. Scoliosis is a lateral curvature of the spine with associated rotation, often causing distress due to appearance. For some curves, there is good evidence to support the use of a spinal brace, worn for 20 to 24 hours a day to minimize the curve, making it as straight as possible during growth, preventing progression. Compliance can be poor due to appearance and comfort. A night-time brace, worn for eight to 12 hours, can achieve higher levels of curve correction while patients are supine, and could be preferable for patients, but evidence of efficacy is limited. This is the protocol for a randomized controlled trial of ‘full-time bracing’ versus ‘night-time bracing’ in adolescent idiopathic scoliosis (AIS). Methods. UK paediatric spine clinics will recruit 780 participants aged ten to 15 years-old with AIS, Risser stage 0, 1, or 2, and curve size (Cobb angle) 20° to 40° with apex at or below T7. Patients are randomly allocated 1:1, to either full-time or night-time bracing. A qualitative sub-study will explore communication and experiences of families in terms of bracing and research. Patient and Public Involvement & Engagement informed study design and will assist with aspects of trial delivery and dissemination. Discussion. The primary outcome is ‘treatment failure’ (Cobb angle progression to 50° or more before skeletal maturity); skeletal maturity is at Risser stage 4 in females and 5 in males, or ‘treatment success’ (Cobb angle less than 50° at skeletal maturity). The comparison is on a non-inferiority basis (non-inferiority margin 11%). Participants are followed up every six months while in brace, and at one and two years after skeletal maturity. Secondary outcomes include the Scoliosis Research Society 22 questionnaire and measures of quality of life, psychological effects of bracing, adherence,
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
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
The number of patients undergoing surgery for degenerative cervical radiculopathy has increased. In many countries, public hospitals have limited capacity. This has resulted in long waiting times for elective treatment and a need for supplementary private healthcare. It is uncertain whether the management of patients and the outcome of treatment are equivalent in public and private hospitals. The aim of this study was to compare the management and patient-reported outcomes among patients who underwent surgery for degenerative cervical radiculopathy in public and private hospitals in Norway, and to assess whether the effectiveness of the treatment was equivalent. This was a comparative study using prospectively collected data from the Norwegian Registry for Spine Surgery. A total of 4,750 consecutive patients who underwent surgery for degenerative cervical radiculopathy and were followed for 12 months were included. Case-mix adjustment between those managed in public and private hospitals was performed using propensity score matching. The primary outcome measure was the change in the Neck Disability Index (NDI) between baseline and 12 months postoperatively. A mean difference in improvement of the NDI score between public and private hospitals of ≤ 15 points was considered equivalent. Secondary outcome measures were a numerical rating scale for neck and arm pain and the EuroQol five-dimension three-level health questionnaire. The duration of surgery, length of hospital stay, and complications were also recorded.Aims
Methods
Postoperative complication rates remain relatively high after adult spinal deformity (ASD) surgery. The extent to which modifiable patient-related factors influence complication rates in patients with ASD has not been effectively evaluated. The aim of this retrospective cohort study was to evaluate the association between modifiable patient-related factors and complications after corrective surgery for ASD. ASD patients with two-year data were included. Complications were categorized as follows: any complication, major, medical, surgical, major mechanical, major radiological, and reoperation. Modifiable risk factors included smoking, obesity, osteoporosis, alcohol use, depression, psychiatric diagnosis, and hypertension. Patients were stratified by the degree of baseline deformity (low degree of deformity (LowDef)/high degree of deformity (HighDef): below or above 20°) and age (Older/Younger: above or below 65 years). Complication rates were compared for modifiable risk factors in each age/deformity group, using multivariable logistic regression analysis to adjust for confounders.Aims
Methods
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

To provide normative data that can assess spinal-related disability and the prevalence of back or leg pain among adults with no spinal conditions in the UK using validated questionnaires. A total of 1,000 participants with equal sex distribution were included and categorized in five age groups: 20 to 29, 30 to 39, 40 to 49, 50 to 59, and 60 to 69 years. Individuals with spinal pathologies were excluded. Participants completed the Scoliosis Research Society-22 (SRS-22r), visual analogue scale (VAS) for back/leg pain, and the EuroQol five-dimension index (EQ-5D/VAS) questionnaires, and disclosed their age, sex, and occupation. They were also categorized in five professional groups: doctors, nurses, allied health professionals, office workers, and manual workers.Aims
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
Methods
The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events. This was a longitudinal observation study. Data from herniated lumbar disc operations were retrieved from a large medical database using a combination of procedure and diagnosis codes from all public hospitals in Norway from 1999 to 2013. The impact of age, gender, geographical affiliation, education, civil status, income, and comorbidity on unfavourable events were analyzed by logistic regression.Aims
Patients and Methods
Cervical spondylosis is often accompanied by dizziness. It has
recently been shown that the ingrowth of Ruffini corpuscles into
diseased cervical discs may be related to cervicogenic dizziness.
In order to evaluate whether cervicogenic dizziness stems from the
diseased cervical disc, we performed a prospective cohort study
to assess the effectiveness of anterior cervical discectomy and
fusion on the relief of dizziness. Of 145 patients with cervical spondylosis and dizziness, 116
underwent anterior cervical decompression and fusion and 29 underwent
conservative treatment. All were followed up for one year. The primary
outcomes were measures of the intensity and frequency of dizziness.
Secondary outcomes were changes in the modified Japanese Orthopaedic
Association (mJOA) score and a visual analogue scale score for neck
pain.Aims

The National Institute for Health and Care Excellence
has issued guidelines that state fusion for non-specific low back
pain should only be performed as part of a randomised controlled
trial, and that lumbar disc replacement should not be performed.
Thus, spinal fusion and disc replacement will no longer be routine
forms of treatment for patients with low back pain. This annotation
considers the evidence upon which these guidelines are based. Cite this article:
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

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
for degenerative disease in patients with, or without post-operative
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

Pain catastrophising is an adverse coping mechanism,
involving an exaggerated response to anticipated or actual pain. The purpose of this study was to investigate the influence of
pain ‘catastrophising’, as measured using the pain catastrophising
scale (PCS), on treatment outcomes after surgery for lumbar spinal
stenosis (LSS). A total of 138 patients (47 men and 91 women, mean age 65.9;
45 to 78) were assigned to low (PCS score <
25, n = 68) and high
(PCS score ≥ 25, n = 70) PCS groups. The primary outcome measure
was the Oswestry Disability Index (ODI) 12 months after surgery.
Secondary outcome measures included the ODI and visual analogue
scale (VAS) for back and leg pain, which were recorded at each assessment
conducted during the 12-month follow-up period The overall changes in the ODI and VAS for back and leg pain
over a 12-month period were significantly different between the
groups (ODI, p <
0.001; VAS for back pain, p <
0.001; VAS
for leg pain, p = 0.040). The ODI and VAS for back and leg pain
significantly decreased over time after surgery in both groups (p
<
0.001 for all three variables). The patterns of change in the
ODI and VAS for back pain during the follow-up period significantly
differed between the two groups, suggesting that the PCS group is
a potential treatment moderator. However, there was no difference
in the ODI and VAS for back and leg pain between the low and high
PCS groups 12 months after surgery. In terms of minimum clinically important differences in ODI scores
(12.8), 22 patients (40.7%) had an unsatisfactory surgical outcome
in the low PCS group and 16 (32.6%) in the high PCS group. There
was no statistically significant difference between the two groups
(p = 0.539). Pre-operative catastrophising did not always result in a poor
outcome 12 months after surgery, which indicates that this could
moderate the efficacy of surgery for LSS. Cite this article:
Randomised controlled trials (RCTs) that assessed
the efficacy of bracing for adolescent idiopathic scoliosis have suffered
from small sample sizes, low compliance and lack of willingness
to participate. The aim of this study was to assess the feasibility
of a comprehensive cohort study for evaluating both the efficacy
and the effectiveness of bracing in patients with adolescent idiopathic
scoliosis. Patients with curves at greater risk of progression were invited
to join a randomised controlled trial. Those who declined were given
the option to remain in the study and to choose whether they wished
to be braced or observed. Of 87 eligible patients (5 boys and 63
girls) identified over one year, 68 (78%) with mean age of 12.5
years (10 to 15) consented to participate, with a mean follow-up
of 168 weeks (0 to 290). Of these, 19 (28%) accepted randomisation.
Of those who declined randomisation, 18 (37%) chose a brace. Patients
who were more satisfied with their image were more likely to choose
bracing (Odds Ratio 4.1; 95% confidence interval 1.1 to 15.0; p = 0.035).
This comprehensive cohort study design facilitates the assessment
of both efficacy and effectiveness of bracing in patients with adolescent
idiopathic scoliosis, which is not feasible in a conventional randomised
controlled trial. 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

reconstitution of the anomalous vertebra. The deformity and radiological

Spinal stenosis and disc herniation are the two
most frequent causes of lumbosacral nerve root compression. This
can result in muscle weakness and present with or without pain. The
difficulty when managing patients with these conditions is knowing
when surgery is better than non-operative treatment: the evidence
is controversial. Younger patients with a lesser degree of weakness
for a shorter period of time have been shown to respond better to surgical
treatment than older patients with greater weakness for longer.
However, they also constitute a group that fares better without
surgery. The main indication for surgical treatment in the management
of patients with lumbosacral nerve root compression should be pain
rather than weakness.
This article reviews the current knowledge of
the intervertebral disc (IVD) and its association with low back
pain (LBP). The normal IVD is a largely avascular and aneural structure
with a high water content, its nutrients mainly diffusing through
the end plates. IVD degeneration occurs when its cells die or become
dysfunctional, notably in an acidic environment. In the process
of degeneration, the IVD becomes dehydrated and vascularised, and
there is an ingrowth of nerves. Although not universally the case,
the altered physiology of the IVD is believed to precede or be associated
with many clinical symptoms or conditions including low back and/or
lower limb pain, paraesthesia, spinal stenosis and disc herniation. New treatment options have been developed in recent years. These
include biological therapies and novel surgical techniques (such
as total disc replacement), although many of these are still in
their experimental phase. Central to developing further methods
of treatment is the need for effective ways in which to assess patients
and measure their outcomes. However, significant difficulties remain
and it is therefore an appropriate time to be further investigating
the scientific basis of and treatment of LBP.
