Lateral Spondylolisthesis is seen as a consequence of degenerative disc disease. It occurs primarily in the lumbar spine, and is often associated with adult degenerative scoliosis. When it occurs, it can result in severe back pain from disc instability and radicular leg pain from nerve root compression [1-6]. This is a descriptive study of a series of 32 patients with Lateral Lumbar Spondylolis...
STUDY DESIGN Retrospective radiographic analysis. OBJECTIVE To determine which lumbar interbody technique is most effective for restoring lordosis, increasing disk height, and reducing spondylolisthesis. SUMMARY OF BACKGROUND DATA Lumbar interbody fusions are performed in hopes of increasing fusion potential, correcting deformity, and indirectly decompressing nerve roots. No published study...
STUDY DESIGN Retrospective study. PURPOSE To compare initial fixation using the cortical bone trajectory (CBT) technique versus conventional pedicle screws (PS) in radiographs of postsurgical lumbar degenerative spondylolisthesis. OVERVIEW OF LITERATURE Few reports have documented the holding strength of CBT technique for spondylolisthesis cases. METHODS From October 2009 to June 2014, 21...
Progression of spondylolysis to spondylolisthesis in adults is very rare. It is always accompanied by disc degeneration at the slip level, or at a lower level. The intervertebral disc is indeed the main structure that opposes the anteriorly directed shear forces. Of course, the disc degeneration might also be a consequence, rather than a cause of the slip. The authors describe an unusual case o...
BACKGROUND The vacuum phenomenon within the intervertebral disc usually represents disc degeneration. There are no reports in the English literature that focus on the effect of an anterior vacuum disc on surgical outcome of same-segment spondylolisthesis. METHODS Patients with degenerative spondylolisthesis (DS) or isthmic spondylolisthesis (IS) who underwent a spinal surgery between January ...
BACKGROUND The two most common types of surgically treated lumbar spondylolisthesis in adults include the degenerative and isthmic types. The aim of this study was to compare the functional outcomes of surgical decompression and posterolateral instrumented fusion in patients with lumbar degenerative and isthmic spondylolisthesis. METHODS In this retrospective study, we reviewed the clinical o...
BACKGROUND In instrumented posterolateral fusion reduction of a spondylolisthesis is appealing on theoretical grounds since this may lead to indirect decompression of the entrapped nerve roots. However, there is no consensus in the literature whether a beneficial effect of reduction on outcome can be expected. The objective of the current study was to evaluate whether a correlation between the ...
We report a case of degenerative L4-L5 spondylolisthesis in a 32-year-old female who had undergone thoracic (lower level T12) fusion as a teenager. All other levels in the lumbar spine were normal on magnetic resonance imaging. Subsequent fusion of L4-L5 led to improvement in function and alleviation of pain for more than 4 years. The possible relationship between the previous fusion and degene...
Spondylolysis is a stress fracture of the pars interarticularis, which in some cases progresses to spondylolisthesis (forward slippage of the vertebral body). This slip progression is prevalent in children and occurs very rarely after spinal maturation. The pathomechanism and predilection for children remains controversial despite considerable clinical and basic research into the disorder over ...
