We present a novel method of performing an ‘open-door’ cervical laminoplasty. The complete laminotomy is sited on alternate sides at successive levels, thereby allowing the posterior arch to be elevated to alternate sides. Foraminotomies can be carried out on either side to relieve root compression. The midline structures are preserved. We undertook this procedure in 23 elderly patients with a spondylotic
Postoperative radiculopathy is a complication of posterior cervical decompression associated with tethering of the nerve root. We reviewed retrospectively 287 consecutive patients with cervical compression

The purpose of this study was to investigate
the clinical predictors of surgical outcome in patients with cervical spondylotic
myelopathy (CSM). We reviewed a consecutive series of 248 patients
(71 women and 177 men) with CSM who had undergone surgery at our
institution between January 2000 and October 2010. Their mean age
was 59.0 years (16 to 86). Medical records, office notes, and operative
reports were reviewed for data collection. Special attention was
focused on pre-operative duration and severity as well as post-operative
persistence of myelopathic symptoms. Disease severity was graded
according to the Nurick classification. Our multivariate logistic regression model indicated that Nurick
grade 2 CSM patients have the highest chance of complete symptom
resolution (p <
0.001) and improvement to normal gait (p = 0.004)
following surgery. Patients who did not improve after surgery had
longer duration of myelopathic symptoms than those who did improve
post-operatively (17.85 months (1 to 101) vs 11.21 months (1 to
69); p = 0.002). More advanced Nurick grades were not associated
with a longer duration of symptoms (p = 0.906). Our data suggest that patients with Nurick grade 2 CSM are most
likely to improve from surgery. The duration of myelopathic symptoms
does not have an association with disease severity but is an independent
prognostic indicator of surgical outcome. Cite this article:
This study evaluates factors related to myelopathic
symptoms in patients with ossification of the posterior longitudinal
ligament (OPLL). A total of 87 patients with OPLL were included.
Of these, 53 (Group I) had no symptoms or presented with neck pain
and radiculopathy and 34 (Group II) had myelopathic symptoms. Gender, age,
and history of trauma were evaluated in the two groups. The range
of movement of the cervical spine was measured using plain radiographs.
The number of involved segments, type of OPLL, and maximal compression ratio
were analysed using CT and signal change in the spinal cord was
evaluated using MRI. The patients’ age was found to be significant (p = 0.001). No
difference was found between gender and the range of movement in
the two groups. The maximum compression of the spinal canal showed
a difference (p = 0.03). The signal change of the spinal cord was
different between the two groups. In patients with OPLL of the cervical
spine, myelopathic symptoms are not related to the range of movement
or the number of involved segments.
Ankylosing spondylitis (AS) is a progressive
multisystem chronic inflammatory disorder. The hallmark of this pathological
process is a progressive fusion of the zygapophyseal joints and
disc spaces of the axial skeleton, leading to a rigid kyphotic deformity
and positive sagittal balance. The ankylosed spine is unable to
accommodate normal mechanical forces, rendering it brittle and susceptible
to injury. Traumatic hyperextension injury of the cervical spine
leading to atlantoaxial subluxation (AAS) in AS patients can often
be fatal. We report a non-traumatic mechanism of injury in AS progressing
to AAS attributable to persistent hyperextension, which resulted
in fatal migration of C2 through the foramen magnum. Cite this article:

Five had progressive weakness and one had recurrent pain in the
lower limbs. There was incomplete recovery following subsequent

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
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
Methods
The aim of this study was to compare outcomes after growth-friendly treatment for early-onset scoliosis (EOS) between patients with skeletal dysplasias versus those with other syndromes. We retrospectively identified 20 patients with skeletal dysplasias and 292 with other syndromes (control group) who had completed surgical growth-friendly EOS treatment between 1 January 2000 and 31 December 2018. We compared radiological parameters, complications, and health-related quality of life (HRQoL) at mean follow-up of 8.6 years (SD 3.3) in the dysplasia group and 6.6 years (SD 2.6) in the control group.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 optimal procedure for the treatment of ossification of the posterior longitudinal ligament (OPLL) remains controversial. The aim of this study was to compare the outcome of anterior cervical ossified posterior longitudinal ligament en bloc resection (ACOE) with posterior laminectomy and fusion with bone graft and internal fixation (PTLF) for the surgical management of patients with this condition. Between July 2017 and July 2019, 40 patients with cervical OPLL were equally randomized to undergo surgery with an ACOE or a PTLF. The clinical and radiological results were compared between the two groups.Aims
