[Short-term clinical results of interspinous dynamic fixation of Coflex for the prevention of adjacent segment degeneration after lumbar fusion].
To observe the short-term clinical results of the adjacent segment degeneration after the implantation of Coflex system at the interspinous space of adjacent segment to lumbar fusion. ⋯ Coflex system can obviously limit the motion range and maintain the disc space height of adjacent segment to lumbar fusion, and prevent its degeneration in some degree.

[The efficacy and complication analysis of interspinous dynamic device (Wallis) in patients of degenerative lumbar disease].
To review degenerative lumbar disease treated with Wallis and the re-herniation cases after the implantation of Wallis, so as to evaluate the effect of the device. ⋯ Although existing problems such as recurrence after surgery, the clinical outcome of Wallis in treating protrusion of lumbar intervertebral disc and lumbar stenosis is satisfied in middle-early stage.

[Device implanted complications of Coflex interspinous dynamic stabilization].
To investigate device implanted complications and corresponding therapeutic strategies of Coflex interspinous dynamic stabilization system for lumbar spine intraoperatively and postoperatively. ⋯ Coflex interspinous dynamic stabilization system implanted should be avoided to cases who suffered with osteoporosis, too narrow interspinous space and intervertebral coronal spondylolysis or sagittal instability; and choice of device, depth of implantation and intensity of clumping should be appropriate. For patients with symptom but device still in right position, conservative treatment can be carried out; but for patients subjected to malposition of device, failure of implantation intraoperatively or intolerance to device, revisions and salvages should be underwent with internal fixation of pedicle screws.
