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
A variety of surgical methods and strategies have been demonstrated for Andersson lesion (AL) therapy. In 2011, we proposed and identified the feasibility of stabilizing the spine without curettaging the vertebral or discovertebral lesion to cure non-kyphotic AL. Additionally, due to the excellent reunion ability of ankylosing spondylitis, we further came up with minimally invasive spinal surgery (MIS) to avoid the need for both bone graft and lesion curettage in AL surgery. However, there is a paucity of research into the comparison between open spinal fusion (OSF) and early MIS in the treatment of AL. The purpose of this study was to investigate and compare the clinical outcomes and radiological evaluation of our early MIS approach and OSF for AL. A total of 39 patients diagnosed with AL who underwent surgery from January 2004 to December 2022 were retrospectively screened for eligibility. Patients with AL were divided into an MIS group and an OSF group. The primary outcomes were union of the lesion on radiograph and CT, as well as the visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores immediately after surgery, and at the follow-up (mean 29 months (standard error (SE) 9)). The secondary outcomes were total blood loss during surgery, operating time, and improvement in the radiological parameters: global and local kyphosis, sagittal vertical axis, sagittal alignment, and chin-brow vertical angle immediately after surgery and at the follow-up.Aims

The aim of this study was to reassess the rate of neurological, psoas-related, and abdominal complications associated with L4-L5 lateral lumbar interbody fusion (LLIF) undertaken using a standardized preoperative assessment and surgical technique. This was a multicentre retrospective study involving consecutively enrolled patients who underwent L4-L5 LLIF by seven surgeons at seven institutions in three countries over a five-year period. The demographic details of the patients and the details of the surgery, reoperations and complications, including femoral and non-femoral neuropraxia, thigh pain, weakness of hip flexion, and abdominal complications, were analyzed. Neurological and psoas-related complications attributed to LLIF or posterior instrumentation and persistent symptoms were recorded at one year postoperatively.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

The aim of this study was to investigate whether the type of cervical disc herniation influences the severity of symptoms at the time of presentation, and the outcome after surgical treatment. The type and extent of disc herniation at the time of presentation in 108 patients who underwent anterior discectomy for cervical radiculopathy were analyzed on MRI, using a four-point scale. These were dichotomized into disc bulge and disc herniation groups. Clinical outcomes were evaluated using the Neck Disability Index (NDI), 36-Item Short Form Survey (SF-36), and a visual analogue scale (VAS) for pain in the neck and arm at baseline and two years postoperatively. The perceived recovery was also assessed at this time.Aims

The outcome following the development of neurological complications after corrective surgery for scoliosis varies from full recovery to a permanent deficit. This study aimed to assess the prognosis and recovery of major neurological deficits in these patients, and to determine the risk factors for non-recovery, at a minimum follow-up of two years. A major neurological deficit was identified in 65 of 8,870 patients who underwent corrective surgery for scoliosis, including eight with complete paraplegia and 57 with incomplete paraplegia. There were 23 male and 42 female patients. Their mean age was 25.0 years (SD 16.3). The aetiology of the scoliosis was idiopathic (n = 6), congenital (n = 23), neuromuscular (n = 11), neurofibromatosis type 1 (n = 6), and others (n = 19). Neurological function was determined by the American Spinal Injury Association (ASIA) impairment scale at a mean follow-up of 45.4 months (SD 17.2). the patients were divided into those with recovery and those with no recovery according to the ASIA scale during follow-up.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

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

The aim of this study was to compare the effect of a percutaneous
radiofrequency heat lesion at the medial branch of the primary dorsal
ramus with a sham procedure, for the treatment of lumbar facet joint
pain. A randomised sham-controlled double blind multicentre trial was
carried out at the multidisciplinary pain centres of two hospitals.
A total of 60 patients aged >
18 years with a history and physical
examination suggestive of facet joint pain and a decrease of ≥ 2
on a numerical rating scale (NRS 0 to 10) after a diagnostic facet
joint test block were included. In the treatment group, a percutaneous
radiofrequency heat lesion (80oC during 60 seconds per
level) was applied to the medial branch of the primary dorsal ramus.
In the sham group, the same procedure was undertaken without for
the radiofrequency lesion. Both groups also received a graded activity
physiotherapy programme. The primary outcome measure was decrease
in pain. A secondary outcome measure was the Global Perceived Effect scale
(GPE).Aims
Patients and Methods
Vertebral compression fractures are the most prevalent complication of osteoporosis and percutaneous vertebroplasty (PVP) has emerged as a promising addition to the methods of treating the debilitating pain they may cause. Since PVP was first reported in the literature in 1987, more than 600 clinical papers have been published on the subject. Most report excellent improvements in pain relief and quality of life. However, these papers have been based mostly on uncontrolled cohort studies with a wide variety of inclusion and exclusion criteria. In 2009, two high-profile randomised controlled trials were published in the
The aim of this study was to evaluate the feasibility
of using the intact S1 nerve root as a donor nerve to repair an avulsion
of the contralateral lumbosacral plexus. Two cohorts of patients
were recruited. In cohort 1, the L4–S4 nerve roots of 15 patients
with a unilateral fracture of the sacrum and sacral nerve injury
were stimulated during surgery to establish the precise functional
distribution of the S1 nerve root and its proportional contribution
to individual muscles. In cohort 2, the contralateral uninjured
S1 nerve root of six patients with a unilateral lumbosacral plexus
avulsion was transected extradurally and used with a 25 cm segment
of the common peroneal nerve from the injured leg to reconstruct
the avulsed plexus. The results from cohort 1 showed that the innervation of S1 in
each muscle can be compensated for by L4, L5, S2 and S3. Numbness
in the toes and a reduction in strength were found after surgery
in cohort 2, but these symptoms gradually disappeared and strength
recovered. The results of electrophysiological studies of the donor
limb were generally normal. Severing the S1 nerve root does not appear to damage the healthy
limb as far as clinical assessment and electrophysiological testing
can determine. Consequently, the S1 nerve can be considered to be
a suitable donor nerve for reconstruction of an avulsed contralateral
lumbosacral plexus. Cite this article:
The aim of this study was first, to determine
whether CT scans undertaken to identify serious injury to the viscera were
of use in detecting clinically unrecognised fractures of the thoracolumbar
vertebrae, and second, to identify patients at risk of ‘missed injury’. We retrospectively analysed CT scans of the chest and abdomen
performed for blunt injury to the torso in 303 patients. These proved
to be positive for thoracic and intra-abdominal injuries in only
2% and 1.3% of cases, respectively. However, 51 (16.8%) showed a
fracture of the thoracolumbar vertebrae and these constituted our subset
for study. There were eight women and 43 men with mean age of 45.2
years (15 to 94). There were 29 (57%) stable and 22 (43%) unstable
fractures. Only 17 fractures (33.3%) had been anticipated after
clinical examination. Of the 22 unstable fractures, 11 (50%) were
anticipated. Thus, within the whole group of 303 patients, an unstable spinal
injury was missed in 11 patients (3.6%); no harm resulted as they
were all protected until the spine had been cleared. A subset analysis
revealed that patients with a high Injury Severity Score, a low
Glasgow Coma Scale and haemodynamic instability were most likely
to have a significant fracture in the absence of positive clinical
findings. This is the group at greatest risk. Clinical examination alone cannot detect significant fractures
of the thoracolumbar spine. It should be combined with CT imaging
to reduce the risk of missed injury.
We compared a group of 46 somatised patients with a control group of 41 non-somatised patients who had undergone elective surgery to the lumbar spine in an attempt to identify pre-operative factors which could predict the outcome. In a prospective single-centre study, the Distress and Risk Assessment method consisting of a modified somatic perception questionnaire and modified Zung depression index was used pre-operatively to identify somatised patients. The type and number of consultations were correlated with functional indicators of outcome, such as the Oswestry disability index and a visual analogue score for pain in the leg after follow-up for six and 12 months. Similar improvements in the Oswestry disability index were found in the somatised and non-somatised groups. Somatised patients who had a good outcome on the Oswestry disability index had an increased number of orthopaedic consultations (50 of 83 patients (60%) vs 29 of 73 patients (39.7%); p = 0.16) and waited less time for their surgery (5.5 months) (

We report the results of vertebral column resection
(VCR) for paediatric patients with spinal deformity. A total of
49 VCRs in paediatric patients from four university hospitals between
2005 and 2009 with a minimum two-year follow-up were retrospectively
identified. After excluding single hemivertebral resections (n =
25) and VCRs performed for patients with myelomeningocele (n = 6),
as well as spondylectomies performed for tumour (n = 4), there were
14 patients who had undergone full VCR at a mean age of 12.3 years
(6.5 to 17.9). The aetiology was congenital scoliosis in five, neuromuscular
scoliosis in three, congenital kyphosis in two, global kyphosis
in two, adolescent idiopathic scoliosis in one and secondary scoliosis
in one. A total of seven anteroposterior and seven posterolateral approaches
were used. The mean major curve deformity was 86° (67° to 120°) pre-operatively
and 37° (17° to 80°) at the two-year follow-up; correction was a
mean of 54% (18% to 86%) in the anteroposterior and 60% (41% to
70%) in the posterolateral group at the two-year follow-up (p =
0.53). The mean Scoliosis Research Society-24 total scores were
100 (92 to 108) for the anteroposterior and 102 (95 to 105) for
the posterolateral group. There was one paraparesis in the anteroposterior
group necessitating urgent re-decompression, with a full recovery. Patients undergoing VCR are highly satisfied after a successful
procedure.
Diastematomyelia is a rare congenital abnormality
of the spinal cord. This paper summarises more than 30 years’ experience
of treating this condition. Data were collected retrospectively
on 138 patients with diastematomyelia (34 males, 104 females) who
were treated at our hospital from May 1978 to April 2010. A total

Low bone mass and osteopenia have been described in the axial and peripheral skeleton of patients with adolescent idiopathic scoliosis (AIS). Recently, many studies have shown that gene polymorphism is related to osteoporosis. However, no studies have linked the association between IL6 gene polymorphism and bone mass in AIS. This study examined the association between bone mass and IL6 gene polymorphism in 198 girls with AIS. The polymorphisms of IL6-597 G→A, IL6-572 G→C and IL6-174 G→A and the bone mineral density in the lumbar spine and femoral neck were analysed and compared with their levels in healthy controls. The mean bone mineral density at both sites in patients with AIS was decreased compared with controls (p = 0.0022 and p = 0.0013, respectively). Comparison of genotype frequencies between AIS and healthy controls revealed a statistically significant difference in IL6-572 G→C polymorphism (p = 0.0305). There was a significant association between the IL6-572 G→C polymorphism and bone mineral density in the lumbar spine, with the CC genotype significantly higher with the GC (p = 0.0124) or GG (p = 0.0066) genotypes. These results suggest that the IL6-572 G→C polymorphism is associated with bone mineral density in the lumbar spine in Korean girls with AIS.
The post-operative changes in the serum levels of CRP and serum amyloid A (SAA) were investigated prospectively in 106 patients after posterior lumbar interbody fusion. In 96 patients who did not have complications related to infection within the first year after operation, the median levels of CRP before operation and on days 3, 7 and 13 after were 0.02 (0.01 to 0.03), 9.12 (2.36 to 19.82), 1.64 (0.19 to 6.10) and 0.53 (0.05 to 2.94) mg/dl, respectively and for SAA, 2.6 (2.0 to 3.8), 1312.1 (58.0 to 3579.8), 77.3 (1.8 to 478.4), 14.1 (0.5 to 71.9) μg/ml, respectively. The levels on day 3 were the highest for both CRP and SAA and significantly decreased (p <
0.01) by day 7 and day 13. In regard to CRP, no patient had less than the reference level (0.1 mg/dl) on day 7. In only three had the level decreased to the reference level, while in 93 it was above this on day 13. However, for SAA, the levels became normal on day 7 in 10 cases and on day 13 in 34 cases. The ratios relative to the levels on day 3 were significantly lower for SAA compared with CRP on day 7 and day 13. Of the ten patients with infection in the early stages, the level of CRP decreased slightly but an increase in SAA was observed in six. We concluded that SAA is better than CRP as a post-operative inflammatory marker.
