Abstract

The aim of our study is to evaluate the clinical and functional outcome following lumbar laminoplasty with posterior element reconstruction with mini-plate and screws for multilevel lumbar canal stenosis. This study was done on 40 patients (18 males and 22 females) of degenerative multilevel lumber canal stenosis patients underwent open double door lumbar laminoplasty with posterior element reconstruction with mini-plate and screws from January 2015 to June 2018. Thirty four patients underwent surgery for 2 level involvement and 6 underwent for 3 level involvement of lumbar canal stenosis. The mean post-operative hospital stay was 5.2 ± 1.1 days. Per-operative complication was dural tear in 2 cases. Pre-operative mean VAS score of back pain and leg pain were 7.0 ± 0.7 and 7.2 ± 1.1 which were significantly reduced to 1.0 ± 0.2 and 1.0 ± 0.8 respectively at final follow-up. All patients were followed-up for minimum 1 year. Pre-operative mean Japanese Orthopedic Association score was 8.6 ± 2.2 which was significantly increased to 14.8 ± 0.4 after 12 months of surgery. Pre-operative mean Oswestry Disability Index was 34.4 ± 3.0 which was significantly reduced to 8.5 ± 2.2 after 12 months of surgery. The outcome of lumbar laminoplasty with posterior element reconstruction with mini-plate and screws for multilevel lumbar canal stenosis show good result and can be one of the good option for the treatment for multilevel lumbar canal stenosis.
