Abstract

Aims: To assess the results of minimally invasive surgery approach for degenerative lumbar spinal stenosis. Methods: From 03/2015 to 09/2016 the surgery was performed on 62 patients (25 men and 37 women; 32-81years; median age, 57,61 ± 9,6 years). We carried out bilateral interlaminar fenestration and unroofing for the decompression of nerve roots by using a unilateral approach. Result: Average of surgical time was 65,00±10,97 minutes for per level, 85,88 ± 18,05 minutes for two levels. Surgical results were classified by JOA score at the last follow up, 58/62 patients, average time 33,47 ± 16,89 months. Excellent: 22 (37,9%), good: 31 (53,4%), fair: 3 (5,1%), poor: 2 (3,6%). VAS back pain improved from 5,03 ± 1,24 to 0,67 ± 1,09, VAS radicular pain improved from 7,23 ± 0,98 to 0,95 ±1,42, ODI improved from 66,32 ± 5,39 to 17,47±11,77, JOA improved from 11,29 ± 1 to 24,39 ± 2,70. The increasing of spinal canal on MRI at the last follow up (35/62 patients)  significant difference (p < 0,001): A-P diameter: 4,82 ± 1,65 mm (pre-op: 6,43 ± 1.34 mm; post-op: 11,25 ±1,59mmm); Dural sac cross-sectional area: 73,06 ± 18,80 mm² (pre-op:49,29 ± 15,09, post-op: 122,35 ± 25,79). Complications: dural tear were 2 (3,2%) and epidural hematoma in 01(1,6%). Conclusion: Minimally invasive surgery is safe, effective and lower rate of complication for degenerative lumbar spinal stenosis.
