Abstract:
Objective To investigate clinical effect of limited decompression under endoscope combined with percutaneous transpedicular screw fixation for treatment of degenerative lumbar spinal stenosis.Methods Thirty-four senile patients with lower lumbar spinal stenosis were selected as our subjects from February 2010 to August 2011,and were treated with limited decompression under endoscope combined with percutaneous transpedicular screw fixation through posterior approach.The VAS scores of all patients were collected at the four periods including pre-operation,leaving hospital,3 months after operation,and the last follow-up.The therapeutic effectiveness for the postoperative follow-up was expressed as excellent,good,ordinary,and poor according to Nakai standard.Results The VAS scores at pre-operation,leaving hospital,3 month after operation,and the last follow-up were (7.9 ± 1.6),(2.9 ± 1.4),(1.9 ± 1.9),(2.4 ± 1.5)respectively,and the difference was significant (F =13.524,P =0.036).But no significant differences of VAS scores at three sequential tests after operation were observed (P ＞ 0.05).In the last postoperative follow-up,32 cases were graded as excellent,1 cases for good and 1 case for ordinary,and the excellent rate reached to 97％.Conclusion The therapeutic effectiveness of lumbar spinal stenosis limited decompression under endoscope combined with percutaneous transpedicular screw fixation is reliable.Furthermore,no side effects on spine and back muscles are observed.
