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
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:
We conducted a prospective follow-up MRI study
of originally asymptomatic healthy subjects to clarify the development
of Modic changes in the cervical spine over a ten-year period and
to identify related factors. Previously, 497 asymptomatic healthy
volunteers with no history of cervical trauma or surgery underwent
MRI. Of these, 223 underwent a second MRI at a mean follow-up of
11.6 years (10 to 12.7). These 223 subjects comprised 133 men and 100
women with a mean age at second MRI of 50.5 years (23 to 83). Modic
changes were classified as not present and types 1 to 3. Changes
in Modic types over time and relationships between Modic changes
and progression of degeneration of the disc or clinical symptoms
were evaluated. A total of 31 subjects (13.9%) showed Modic changes at
follow-up: type 1 in nine, type 2 in 18, type 3 in two, and types In the cervical spine over a ten-year period
We describe three patients with pre-ganglionic (avulsion) injuries of the brachial plexus which caused a partial Brown-Séquard syndrome.
