Cervical endoscopic versus open foraminotomy for uncovertebral
An MRI scan was undertaken which showed right-sided cervical foraminal stenosis (with uncovertebral
and facet joint osteophytic changes at C3/4 and C4/5) (Figure 3).
Magnetic Resonance Imaging of the cervical spine was positive for degenerative changes in the cervical spine, multilevel disc desiccation at C2-C5 without disc height loss, C2-C3 and C3-C4 disc bulge with uncovertebral
joint hypertrophy and bilateral neural foraminal narrowing, and spinal canal stenosis (Figure 1(a)).
Radiographic studies indicated moderate osteopenia, mild degenerative disc disease from T4-T9, mild uncovertebral
arthrosis at C5-C6 and a mild s-shaped thoracolumbar curve (<15 [degrees] Cobb angle) (See Figure 1).
Comparison of clinical and radiographic outcome in instrumented anterior cervical discectomy and fusion with or without direct uncovertebral
degenarative changes of the uncovertebral
and zygapophyseal joints (70-75% of cases) (3,A,8).
X rays showed no instability but demonstrated moderate degenerative disc disease at C5-C6 with uncovertebral
hypertrophic spurring on the left at C5-C6.
Each segment of the subaxial spine allows for coupled rotation and lateral bending, due to the unique shape of the uncovertebral
articulation and facet joints, which further increases the functional range of cervical motion.
For example Case 34 "Uncovertebral
osteoarthrosis" provides clear clinical reasoning that results in a reasonable explanation for persistent migraine type headaches and a concurrent cervical spine source for neck pain also radiating into the head.
joint was identified laterally on both sides, and right uncovertebral
joint was resected completely with great care to avoid damage to the vertebral artery.
The cervical radiographs (Figures 1A, 1B, and 1C) revealed: 1) atlantodental space measured 6 mm, indicating anterior atlantoaxial subluxation and potential sagittal atlantoaxial instability, with borderline spinal stenosis at C1; 2) degenerative disc disease from C3-7 with central stenosis at C4 and C5; 3) moderate uncovertebral
arthrosis at C3-4, C4-5, C5-6 and C6-7; 4) postural alterations; 5) moderate osteopenia; and 6) arteriosclerosis of aortic knob.
