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

A characteristic dysfunction of the hand has been observed in various cervical spinal disorders when there is involvement of the spinal cord. There is loss of power of adduction and extension of the ulnar two or three fingers and an inability to grip and release rapidly with these fingers. These changes have been termed "myelopathy hand" and appear to be due to pyramidal tract involvement. The characteristic nature of the signs permit the distinction between

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.
