Meta Analysis[Unilateral versus bilateral pedicle screw fixation in lumbar spinal fusion: a meta-analysis of available evidence].
To evaluate the effectiveness of unilateral versus bilateral pedicle screw fixation in lumbar spinal fusion. ⋯ Both unilateral and bilateral pedicle screw fixation are effective in lumbar spinal fusion. To compare with bilateral fixation, unilateral fixation can shorten operation time, reduce amount of bleeding and medical expenses. And there is a similar effect of inpatient stay, fusion rate, complication rate and excellent and good rate.

[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.

[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.

[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.
