The aim of this study was to determine whether the sequential
application of povidone iodine-alcohol (PVI) followed by chlorhexidine
gluconate-alcohol (CHG) would reduce surgical wound contamination
to a greater extent than PVI applied twice in patients undergoing
spinal surgery. A single-centre, interventional, two arm, parallel group randomised
controlled trial was undertaken, involving 407 patients who underwent
elective spinal surgery. For 203 patients, the skin was disinfected before surgery using
PVI (10% [w/w (1% w/w available iodine)] in 95% industrial denatured
alcohol, povidone iodine; Videne Alcoholic Tincture) twice, and
for 204 patients using PVI once followed by CHG (2% [w/v] chlorhexidine
gluconate in 70% [v/v] isopropyl alcohol; Chloraprep with tint).
The primary outcome measure was contamination of the wound determined
by aerobic and anaerobic bacterial growth from samples taken after
disinfection.Aims
Patients and Methods
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

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
Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors need to be identified. The objective of this study was to identify the pre-operative prognostic factors related to the effect of vertebroplasty on acute pain control using a cohort of surgically and non-surgically managed patients. Patients with single-level acute osteoporotic vertebral compression fracture at thoracolumbar junction (T10 to L2) were followed. If the patients were not satisfied with acute pain reduction after a three-week conservative treatment, vertebroplasty was recommended. Pain assessment was carried out at the time of diagnosis, as well as three, four, six, and 12 weeks after the diagnosis. The effect of vertebroplasty, compared with conservative treatment, on back pain (visual analogue score, VAS) was analysed with the use of analysis-of-covariance models that adjusted for pre-operative VAS scores.Objectives

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

The aims of our study were to provide long-term information on
the behaviour of the thoracolumbar/lumbar (TL/L) curve after thoracic
anterior correction and fusion (ASF) and to determine the impact
of ASF on pulmonary function. A total of 41 patients (four males, 37 females) with main thoracic

The widespread use of MRI has revolutionised
the diagnostic process for spinal disorders. A typical protocol
for spinal MRI includes T1 and T2 weighted sequences in both axial
and sagittal planes. While such an imaging protocol is appropriate
to detect pathological processes in the vast majority of patients,
a number of additional sequences and advanced techniques are emerging.
The purpose of the article is to discuss both established techniques
that are gaining popularity in the field of spinal imaging and to
introduce some of the more novel ‘advanced’ MRI sequences with examples
to highlight their potential uses. 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

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 consensus needs to be reached on the best method
of calculating the MCID. This then needs to be defined for each
spinal procedure. Using a blanket value for the MCID for all spinal
procedures should be avoided. Cite this article:
Back pain is a common symptom in children and
adolescents. Here we review the important causes, of which defects
and stress reactions of the pars interarticularis are the most common
identifiable problems. More serious pathology, including malignancy
and infection, needs to be excluded when there is associated systemic
illness. Clinical evaluation and management may be difficult and
always requires a thorough history and physical examination. Diagnostic
imaging is obtained when symptoms are persistent or severe. Imaging
is used to reassure the patient, relatives and carers, and to guide
management. Cite this article:
Whether to combine spinal decompression with
fusion in patients with symptomatic lumbar spinal stenosis remains
controversial. We performed a cohort study to determine the effect
of the addition of fusion in terms of patient satisfaction after
decompressive spinal surgery in patients with and without a degenerative spondylolisthesis. The National Swedish Register for Spine Surgery (Swespine) was
used for the study. Data were obtained for all patients in the register
who underwent surgery for stenosis on one or two adjacent lumbar
levels. A total of 5390 patients fulfilled the inclusion criteria
and completed a two-year follow-up. Using multivariable models the
results of 4259 patients who underwent decompression alone were
compared with those of 1131 who underwent decompression and fusion.
The consequence of having an associated spondylolisthesis in the
operated segments pre-operatively was also considered. At two years there was no significant difference in patient satisfaction
between the two treatment groups for any of the outcome measures,
regardless of the presence of a pre-operative spondylolisthesis.
Moreover, the proportion of patients who required subsequent further
lumbar surgery was also similar in the two groups. In this large cohort the addition of fusion to decompression
was not associated with an improved outcome. Cite this article:
Dysphagia is a common complication of anterior
surgery of the cervical spine. The incidence of post-operative dysphagia
may be as high as 71% within the first two weeks after surgery,
but gradually decreases during the following months. However, 12%
to 14% of patients may have some persistent dysphagia one year after
the procedure. It has been shown that female gender, advanced age,
multilevel surgery, longer operating time and severe pre-operative
neck pain may be risk factors. Although the aetiology remains unclear
and is probably multifactorial, proposed causes include oesophageal
retraction, prominence of the cervical plate and prevertebral swelling.
Recently, pre-operative tracheal traction exercises and the use
of retropharyngeal steroids have been proposed as methods of reducing
post-operative dysphagia. We performed a systematic review to assess the incidence, aetiology,
risk factors, methods of assessment and management of dysphagia
following anterior cervical spinal surgery. Cite this article:
In a retrospective cohort study we compared the
clinical outcome and complications, including dysphagia, following
anterior cervical fusion for the treatment of cervical spondylosis
using either a zero-profile (Zero-P; Synthes) implant or an anterior
cervical plate and cage. A total of 83 patients underwent fusion
using a Zero-P and 107 patients underwent fusion using a plate and
cage. The mean follow-up was 18.6 months ( When compared with the traditional anterior cervical plate and
cage, the Zero-P implant is a safe and convenient procedure giving
good results in patients with symptomatic cervical spondylosis with
a reduced incidence of dysphagia post-operatively. Cite this article:
