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 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 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

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. Patients and Methods. 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. Results. There was a statistically significant relationship between greater
facet distraction and increased NDI and VAS pain scores. This was
further confirmed by Spearman correlation, which showed evidence
of a moderate correlation between both NDI score and facet joint
distraction (Spearman correlation coefficient 0.34; p < 0.001)
and VAS score and facet distraction (Spearman correlation coefficient
0.52; p < 0.001). Furthermore, there was a discernible transition
point between outcome scores. Significantly worse outcomes, in terms
of both NDI scores (17.8 vs 8.2; p < 0.001)
and VAS scores (4.5 vs 1.3; p < 0.001), were
seen with facet distraction of 3 mm or more. Patients who went on
to have a posterior fusion also had increased NDI and VAS scores,
independent of facet distraction. Conclusion. After undergoing ACDF for the treatment of
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

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:
We investigated the incidence of anomalies in
the vertebral arteries and Circle of Willis with three-dimensional
CT angiography in 55 consecutive patients who had undergone an instrumented
posterior fusion of the cervical spine. We recorded any peri-operative and post-operative complications.
The frequency of congenital anomalies was 30.9%, abnormal vertebral
artery blood flow was 58.2% and vertebral artery dominance 40%. The posterior communicating artery was occluded on one side in
41.8% of patients and bilaterally in 38.2%. Variations in the vertebral
arteries and Circle of Willis were not significantly related to
the presence or absence of posterior communicating arteries. Importantly,
18.2% of patients showed characteristic variations in the Circle
of Willis with unilateral vertebral artery stenosis or a dominant
vertebral artery, indicating that injury may cause lethal complications.
One patient had post-operative cerebellar symptoms due to intra-operative
injury of the vertebral artery, and one underwent a different surgical
procedure because of insufficient collateral circulation. Pre-operative assessment of the vertebral arteries and Circle
of Willis is essential if a posterior spinal fusion with instrumentation
is to be carried out safely. Cite this article:

The most common injury in rugby resulting in
spinal cord injury (SCI) is cervical facet dislocation. We report
on the outcome of a series of 57 patients with acute SCI and facet
dislocation sustained when playing rugby and treated by reduction
between 1988 and 2000 in Conradie Hospital, Cape Town. A total of
32 patients were completely paralysed at the time of reduction.
Of these 32, eight were reduced within four hours of injury and
five of them made a full recovery. Of the remaining 24 who were
reduced after four hours of injury, none made a full recovery and only
one made a partial recovery that was useful. Our results suggest
that low-velocity trauma causing SCI, such as might occur in a rugby
accident, presents an opportunity for secondary prevention of permanent
SCI. In these cases the permanent damage appears to result from
secondary injury, rather than primary mechanical spinal cord damage.
In common with other central nervous system injuries where ischaemia
determines the outcome, the time from injury to reduction, and hence
reperfusion, is probably important. In order to prevent permanent neurological damage after rugby
injuries, cervical facet dislocations should probably be reduced
within four hours of injury.
The effect of rheumatoid arthritis on the anatomy of the cervical spine has not been clearly documented. We studied 129 female patients, 90 with rheumatoid arthritis and 39 with other pathologies (the control group). There were 21 patients in the control group with a diagnosis of cervical spondylotic myelopathy, and 18 with ossification of the posterior longitudinal ligament. All had plain lateral radiographs taken of the cervical spine as well as a reconstructed CT scan. The axial diameter of the width of the pedicle, the thickness of the lateral mass, the height of the isthmus and internal height were measured. The transverse diameter of the transverse foramen (d1) and that of the spinal canal (d2) were measured, and the ratio d1/d2 calculated. The width of the pedicles and the thickness of the lateral masses were significantly less in patients with rheumatoid arthritis than in those with other pathologies. The area of the transverse foramina in patients with rheumatoid arthritis was significantly greater than that in the other patients. The ratio of d1 to d2 was not significantly different. A high-riding vertebral artery was noted in 33.9% of the patients with rheumatoid arthritis and in 7.7% of those with other pathologies. This difference was statistically significant. In the rheumatoid group there was a significant correlation between isthmus height and vertical subluxation and between internal height and vertical subluxation.
We have reviewed our experience in managing 11 patients who sustained an indirect sternal fracture in combination with an upper thoracic spinal injury between 2003 and 2006. These fractures have previously been described as ‘associated’ fractures, but since the upper thorax is an anatomical entity composed of the upper thoracic spine, ribs and sternum joined together, we feel that the term ‘fractures of the upper transthoracic cage’ is a better description. These injuries are a challenge because they are unusual and easily overlooked. They require a systematic clinical and radiological examination to identify both lesions. This high-energy trauma gives severe devastating concomitant injuries and CT with contrast and reconstruction is essential after resuscitation to confirm the presence of all the lesions. The injury level occurs principally at T4–T5 and at the manubriosternal joint. These unstable fractures need early posterior stabilisation and fusion or, if treated conservatively, a very close follow-up.
Fracture of the atlas is rare in children. We report a case of fracture of the atlas through a synchondrosis of the anterior arch complicated by atlantoaxial rotatory fixation in a four-year-old girl.

Neck injury of the whiplash type may lead to the cranial symptoms of the Barre-Lieou syndrome. Forty patients with this syndrome and 40 without it were investigated by a variety of imaging techniques. There was a clear correlation between root sleeve defects at C3/4 shown by special oblique myelographic views and cranial symptoms. Good results were obtained by anterior cervical discectomy and fusion at C3/4 in 21 cases. It is suggested that the syndrome may result from irritation of the sympathetic nervous supply at this level.
