: 34 patients followed minimal invasive foraminal decompression in adult degeneration scoliosis from Jan 2018 to Oct 2019. Of the 34 patients 25 were females and 9 were males. The mean age was 63 years. The mean follow up period was 1 ± 0.5 years. All patients underwent pre- and postoperative assessment of VAS, Oswestry Disability Index, CT, MRI, electromyography. Sagittal balance parameters were calculated based on total body radiographs. A retrospective evaluation of the treatment outcomes were performed one year after surgery. The severity of pain was assessed by VAS and Oswestry Disability Index. Sagittal balance parameters were estimated based on the total body radiographs: PI, PT, SS, LL and PI - LL modifier were calculated. In 8 patients of the first group (23%), axial pain syndrome was retrospectively revealed. The VAS changed slightly from 8,11 ± 0,67 to 5,32 ± 0,51 (p <0.001). The PI - LL modifier was more than 35 degrees. Cobb angle was mere then 35 degrees. The Oswestry Disability Index changed from 74,81 ± 6,32 preoperatively to 37,68 ± 3,71 postoperatively. Subsequently, 4 patients of this group underwent reconstructive surgery on the spine using pedical screws and cages. In 26 patients (77%) sagittal balance parameters were normal after surgery. The PI - LL was less than 20 degrees. The Oswestry index changed from 78,14 ± 5,68 preoperatively to 8,32 ± 1,87 postoperatively, VAS changed from 8,68 ± 0,50 to 1,37 ± 0,51 (p <0.001). The results of surgical treatment were affected by the correct assessment of the prevailing pain syndrome, the preoperative dynamics of changes in the sagittal and frontal balance, modifier PI - LL, deformity angle. Conclusions: Isolated endoscopic decompression may be an alternative to reconstructive spinal surgery using pedical screws and cages in patients with adult degenerative scoliosis
