Case
Study #1
Postoperative Hypermobile Instability
The recumbent scan for this patient with recurrent low back pain
and polyradiculopathy following L4-S1 laminectomy and fusion is
shown on the left. The upright scan (right) shows postoperative
intersegmental hypermobile instability associated with fluctuating
stenosis of the central spinal canal at the level above the fusion.

Study #2
Upright Dynamic MRI Reveals Hidden Disc Herniation
The axial standing-extension gradient echo image (right) demonstrates
a focal posterior disc Herniation at the C4/5 level not visible
on the recumbent scan. Note associated spinal cord compression on
the standing-extension scan.
Case
Study #3
Evaluation of Spinal Stability
The recumbent scan (left) demonstrates minor degenerative anterolisthesis
at L4/5. The upright-flexion study (right) reveals further anterior
slip of L4 on L5. These scans show hypermobile translational spinal
instability, which can be a surgical indication in case of related
low back pain.

Study #4
Position Related Recurrent Disc Herniation
The recumbent scan for this patient with right-sided Radiculopathy
following partial Discectomy is shown on the left. The upright
scan (right) shows a disc Herniation at L5/S1.
Case
Study #5
Instability of L4-5 Vertebral Body in Weight Bearing
Clearly defined motion/instability of L4 with respect to
L5 vertebral body with subluxation, which worsens in weight bearing
images. This indicates instability and possible need for surgical
intervention. Note substantial change in disc heights at L2-3,
L3-4, L4-5, and L5-S1.
