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.

However, to date, studies on the biomechanics of the cervical spine have not assessed the role of coupled motions in the lumbar spine. Accordingly, we investigated the biomechanics of the cervical spine following

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
