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

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

Developmental cervical spinal stenosis (DcSS) is a well-known predisposing factor for degenerative cervical myelopathy (DCM) but there is a lack of consensus on its definition. This study aims to define DcSS based on MRI, and its multilevel characteristics, to assess the prevalence of DcSS in the general population, and to evaluate the presence of DcSS in the prediction of developing DCM. This cross-sectional study analyzed MRI spine morphological parameters at C3 to C7 (including anteroposterior (AP) diameter of spinal canal, spinal cord, and vertebral body) from DCM patients (n = 95) and individuals recruited from the general population (n = 2,019). Level-specific median AP spinal canal diameter from DCM patients was used to screen for stenotic levels in the population-based cohort. An individual with multilevel (≥ 3 vertebral levels) AP canal diameter smaller than the DCM median values was considered as having DcSS. The most optimal cut-off canal diameter per level for DcSS was determined by receiver operating characteristic analyses, and multivariable logistic regression was performed for the prediction of developing DCM that required surgery.Aims

This review provides a concise outline of the advances made in the care of patients and to the quality of life after a traumatic spinal cord injury (SCI) over the last century. Despite these improvements reversal of the neurological injury is not yet possible. Instead, current treatment is limited to providing symptomatic relief, avoiding secondary insults and preventing additional sequelae. However, with an ever-advancing technology and deeper understanding of the damaged spinal cord, this appears increasingly conceivable. A brief synopsis of the most prominent challenges facing both clinicians and research scientists in developing functional treatments for a progressively complex injury are presented. Moreover, the multiple mechanisms by which damage propagates many months after the original injury requires a multifaceted approach to ameliorate the human spinal cord. We discuss potential methods to protect the spinal cord from damage, and to manipulate the inherent inhibition of the spinal cord to regeneration and repair. Although acute and chronic SCI share common final pathways resulting in cell death and neurological deficits, the underlying putative mechanisms of chronic SCI and the treatments are not covered in this review.
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

The current pandemic caused by COVID-19 is the biggest challenge for national health systems for a century. While most medical resources are allocated to treat COVID-19 patients, several non-COVID-19 medical emergencies still need to be treated, including vertebral fractures and spinal cord compression. The aim of this paper is to report the early experience and an organizational protocol for emergency spinal surgery currently being used in a large metropolitan area by an integrated team of orthopaedic surgeons and neurosurgeons. An organizational model is presented based on case centralization in hub hospitals and early management of surgical cases to reduce hospital stay. Data from all the patients admitted for emergency spinal surgery from the beginning of the outbreak were prospectively collected and compared to data from patients admitted for the same reason in the same time span in the previous year, and treated by the same integrated team.Aims

The timing of surgical fixation in spinal fractures is a contentious topic. Existing literature suggests that early stabilization leads to reduced morbidity, improved neurological outcomes, and shorter hospital stay. However, the quality of evidence is low and equivocal with regard to the safety of early fixation in the severely injured patient. This paper compares complication profiles between spinal fractures treated with early fixation and those treated with late fixation. All patients transferred to a national tertiary spinal referral centre for primary surgical fixation of unstable spinal injuries without preoperative neurological deficit between 1 July 2016 and 20 October 2017 were eligible for inclusion. Data were collected retrospectively. Patients were divided into early and late cohorts based on timing from initial trauma to first spinal operation. Early fixation was defined as within 72 hours, and late fixation beyond 72 hours.Aims

Severe spinal deformity in growing patients often requires surgical management. We describe the incidence of spinal deformity surgery in a National Health Service. Descriptive study of prospectively collected data. Clinical data of all patients undergoing surgery for spinal deformity between 2005 and 2018 was collected, compared to the demographics of the national population, and analyzed by underlying aetiology.Aims

The aim of this study was to explore the prognostic factors for postoperative neurological recovery and survival in patients with complete paralysis due to neoplastic epidural spinal cord compression. The medical records of 135 patients with complete paralysis due to neoplastic cord compression were retrospectively reviewed. Potential factors including the timing of surgery, muscular tone, and tumour characteristics were analyzed in relation to neurological recovery using logistical regression analysis. The association between neurological recovery and survival was analyzed using a Cox model. A nomogram was formulated to predict recovery.Aims

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

Reviewing our experience of scoliosis in children with a Cavopulmonary Shunt or Fontan circulation and the cardiovascular challenges that this presents. A notes and x ray review was performed. Special attention was paid to the changes in cardiovascular status whilst prone. The review was from first presentation to latest follow up. There were 6 patients who underwent 7 major procedures between 2001 and 2009. All had cardiac procedures in early life. Both definitive fusion and growing instrumentation was used. All procedures were successful. Growing instrumentation allowed
The primary aim of this study was to evaluate the performance
and safety of magnetically controlled growth rods in the treatment
of early onset scoliosis. Secondary aims were to evaluate the clinical
outcome, the rate of further surgery, the rate of complications,
and the durability of correction. We undertook an observational prospective cohort study of children
with early onset scoliosis, who were recruited over a one-year period
and followed up for a minimum of two years. Magnetically controlled
rods were introduced in a standardized manner with distractions
performed three-monthly thereafter. Adverse events which were both related
and unrelated to the device were recorded. Ten children, for whom
relevant key data points (such as demographic information, growth
parameters, Cobb angles, and functional outcomes) were available,
were recruited and followed up over the period of the study. There
were five boys and five girls. Their mean age was 6.2 years (2.5
to 10).Aims
Patients and 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. Consensus guidelines from the Society of British Neurological
Surgeons and British Association of Spinal Surgeons recommend decompressive
surgery as soon as practically possible which for many patients
will be urgent/emergency surgery at any hour of the day or night. Cite this article:
We describe 13 patients with cerebral palsy and
lordoscoliosis/hyperlordosis of the lumbar spine who underwent a posterior
spinal fusion at a mean age of 14.5 years (10.8 to 17.4) to improve
sitting posture and relieve pain. The mean follow-up was 3.3 years
(2.2 to 6.2). The mean pre-operative lumbar lordosis was 108° (80
to 150°) and was corrected to 62° (43° to
85°); the mean thoracic kyphosis from 17° (-23° to
35°) to 47° (25° to 65°);
the mean scoliosis from 82° (0° to 125°)
to 22° (0° to 40°); the mean pelvic
obliquity from 21° (0° to 38°)
to 3° (0° to 15°); the mean sacral
slope from 79° (54° to 90°) to
50° (31° to 66°). The mean pre-operative
coronal imbalance was 5 cm (0 cm to 8.9 cm) and was corrected to
0.6 cm (0 to 3.2). The mean sagittal imbalance of -8 cm (-16 cm
to 7.8 cm) was corrected to -1.6 cm
(-4 cm to 2.5 cm). The mean operating time was 250 minutes (180
to 360 minutes) and intra-operative blood loss 0.8 of estimated
blood volume (0.3 to 2 estimated blood volume). The mean intensive
care and hospital stay were 3.5 days (2 to 8) and 14.5 days (10
to 27), respectively. Three patients lost a significant amount of
blood intra-operatively and subsequently developed chest or urinary
infections and superior mesenteric artery syndrome. An increased pre-operative lumbar lordosis and sacral slope were
associated with increased peri-operative morbidity: scoliosis and
pelvic obliquity were not. A reduced lumbar lordosis and increased
thoracic kyphosis correlated with better global sagittal balance
at follow-up. All patients and their parents reported excellent
surgical outcomes. Lordoscoliosis and hyperlordosis are associated with significant
morbidity in quadriplegic patients. They are rare deformities and
their treatment is challenging. Sagittal imbalance is the major
component: it can be corrected by posterior fusion of the spine
with excellent functional results. Cite this article:
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.
The identification of the extent of neural damage
in patients with acute or chronic spinal cord injury is imperative for
the accurate prediction of neurological recovery. The changes in
signal intensity shown on routine MRI sequences are of limited value
for predicting functional outcome. Diffusion tensor imaging (DTI)
is a novel radiological imaging technique which has the potential
to identify intact nerve fibre tracts, and has been used to image
the brain for a variety of conditions. DTI imaging of the spinal
cord is currently only a research tool, but preliminary studies
have shown that it holds considerable promise in predicting the
severity of spinal cord injury. This paper briefly reviews our current knowledge of this technique.
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) (
Anterior debridement, grafting of the defect and posterior instrumentation as a single-stage procedure is a controversial method of managing pyogenic vertebral osteomyelitis. Between 1994 and 2005, 37 patients underwent this procedure at our hospital, of which two died and three had inadequate follow-up. The remaining 32 were reviewed for a mean of 36 months (12 to 66). Their mean age was 48 years (17 to 68). A significant pre-operative neurological deficit was present in 13 patients (41%). The mean duration of surgery was 285 minutes (240 to 360) and the mean blood loss was 900 ml (300 to 1600). Pyogenic organisms were isolated in 21 patients (66%). All patients began to mobilise on the second post-operative day. The mean hospital stay was 13.6 days (10 to 20). Appropriate antibiotics were administered for 10 to 12 weeks. Early wound infection occurred in four patients (12.5%), and late infection in two (6.3%). At final follow-up, the infection had resolved in all patients, neurological recovery was seen in ten of 13 (76.9%) and interbody fusion had occurred in 30 (94%). The clinical outcome was excellent or good in 30 patients according to Macnab’s criteria. This surgical protocol can be used to good effect in patients with pyogenic vertebral osteomyelitis when combined with appropriate antibiotic therapy.
