Retrolisthesis After Spinal Fusion

The incidence and clinical features of asd were based on data from the 28 patients who required and underwent revision surgery. L5s1 was initially fused in 7 patients, while 21 patients underwent floating fusion. Our patient unexpectedly experienced severe retrolisthesis at the adjacent intermediate segment despite insertion of an interspinous u at upper level and fusion at lower level.

Numerous biomechanical studies have confirmed that the fusion process imposes significant additional stress on adjacent segments, and a radiographic analysis found that posterior fusion increased the mobility of remaining free segments. Patients less than 35 years of age at the index spinal fusion, patients with uninstrumented fusion, and patients who had not achieved successful union were excluded. Preoperative t2-weighted magnetic resonance imaging shows spinal stenosis at l2-3 and l3-4, and spondylolisthesis at l4-5.

Of the latter, only one (case 10, l5s1) developed distal asd. Unfortunately, fusion alters the normal biomechanics of the spine, and a loss of motion at fused levels is compensated for by increasing motion at adjacent unfused segments. Students test was used to compare average ages at index fusion surgery between the patients with asd (28 patients) and the patients without asd (1,041 patients) in the fusion population.

Wiltse ll, radecki se, biel hm, dimartino pp, oas ra, farjalla g, ravessoud fa, wohletz c. Disc degeneration is a common finding adjacent to a fused segment, and listhesis, instability, hypertrophic facet joint arthritis, herniated nucleus pulposus, and stenosis have also been reported as asd. Ghiselli g, wang jc, bhatia nn, hsu wk, dawson eg. Dekutoski mb, schendel mj, ogilvie jw, olsewski jm, wallace lj, lewis jl. The disease group consisted of 26 of the 28 patients with asd, excluding the 2 patients for whom we did not have initial mri data.

Retrolisthesis After Spinal Fusion

Furthermore, the recent dramatic increase in the number of spinal fusions performed has been accompanied by a commensurate increase in asd. The measurement of observer agreement for categorical data. Our patient unexpectedly experienced severe retrolisthesis at the adjacent intermediate segment despite insertion of an interspinous u at upper level and fusion at lower level.

When facets and a disc degenerate, the translation of an adjacent segment may occur and produce retrolisthesis. A better determination of fusion levels during operative planning requires the ability to predict whether preexisting disc or facet degeneration will cause asd in the future. The procedure involves distraction of the posterior elements of adjacent vertebral bodies, and increase of canal and foraminal dimensions at the expense of limiting spine extension.

As a result, this segmental kyphosis can accelerate the retrolisthesis on the adjacent level as a compensatory mechanism to maintain a global balance. Minimum 2-year follow-up result of degenerative spinal stenosis treated with interspinous u (coflex) webb h, van woerden h. Compensatory mechanisms contributing to keep the sagittal balance of the spine.

Adjacent segment degeneration after lumbar spinal posterolateral fusion with instrumentation in elderly patients. Shono y, kaneda k, abumi k, mcafee pc, cunningham bw. After surgery, complete pain relief was achieved and he was able to ambulate without difficulty.

Preexisting facet degeneration may be associated with a high risk of adjacent segment problems. Fishers exact test was also performed for the four categorical variables on plain radiographs. Instrumented spinal fusion has been recommended for anticipated postoperative instability after wide decompression, unstable spondylolisthesis, and degenerative scoliosis.

In one patient (case 3), spinal stenosis developed in the intervening segment after skip fusions at l23 and l45. In general, back pain and radiating leg pain were relatively severe, although they were not quantitated. Interspinous devices for lumbar stenosis-a review of the literature. Although we observed a relatively low incidence of asd after lumbar or lumbosacral fusion requiring surgery, patients with asd had relatively severe symptoms and frequent neurological abnormalities. Note that the l5s1 segment does not show any deterioration of degeneration interobserver agreement for grading of disc and facet joints in initial mri was substantial and fair with weighted kappa coefficients of 0.
