title: [Comparison of the clinical efficacy between simple vertebral canal decompression and decompression plus laminoplasty].
abstract: OBJECTIVE
  To observe the clinical efficacy of the simple expansion of the spinal canal decompression, decompression plus hydroxyapatite/polyamide artificial lamina reconstruction, and decompression plus titanium mesh reconstruction in the treatment of spinal canal stenosi.
  
  
  METHODS
  A total of 39 patients with lumbar spinal stenosis (with or without disc herniation, spondylolisthesis less than I degree), who received therapy of surgery from January, 2011 to January, 2012, were retrospectively analyzed. All patients were divided into 3 groups: a laminectomy surgery alone group (group A, n=15), a decompression plus hydroxyapatite/polyamide artificial lamina reconstruction group (group B, n=14), and a laminectomy decompression plus reconstruction with titanium mesh group (group C, n=10). Intraoperative situation, the postoperative excellent rate and JOA score were analyzed.
  
  
  RESULTS
  The duration and blood loss in surgery in group A was much less than that in the group B and C (P<0.05), but there was no statistical significance between the group B and C. The postoperative excellent rate in three groups were similar in 3 months (P>0.05). Twelve months after the surgery, the group B and C showed advantage over the group A (P<0.05). JOA scores in 3 and 12 months after the surgery were all greater than that before the surgery (P<0.05). There was no difference in excellent rates in 3 groups in 3 months after the operation (P>0.05); the group B and C showed advantage over the group A in 12 months after the operation (P<0.05). No serious complications were related to the surgery in the 3 groups. Imaging changes were not significant difference.
  
  
  CONCLUSIONS
  The decompression plus hydroxyapatite/polyamide artificial lamina reconstruction and the decompression plus titanium mesh reconstruction show advantages in long-term effect over the simple vertebral canal decompression.
