Objective. To analyze the results of the use of minimally invasive technologies in the treatment of patients with degenerative deformity of the lumbar spine. Material and Methods. Design: Single-center, non-randomized continuous retrospective cohort study. The level of evidence is 3b (UK Oxford, version 2009). A total of 57 patients (10 men and 47 women) were operated for degenerative scoliosis of the lumbar spine using minimally invasive techniques. The quality of life indicators using ODI, SF-36, VAS, as well as linear and angulometric parameters of the spine were studied. Results. The age of patients ranged from 37 to 81 years (62/62 [55; 67], hereinafter the data format is mean/median [1; 3rd quartile]). In the postoperative period, patients operated on with MIS techniques showed a statistically significant decrease in pain by 4.3/4.0 [3; 6] points in the lumbar spine, and by 4.3/4.0 [3; 6] points in the legs. Quality of life indicators according to ODI improved by 24/23 [19; 29], and the level of functional adaptation according to the SF-36 questionnaire – by 18/18 [14; 21] in terms of physical parameters and by 18/20 [16; 23] in terms of mental parameters. The deformity angle in the frontal plane according to Cobb decreased by 12.9°/13.0° [10°; 17°], lumbar lordosis changed by 3.3°/2.0° [-1°; 7°], segmental angle L4–S1 – by 1.0°/0.0° [-5°; 7°], and SVA changed by -7.5/-2.0 [-29; 15] mm. As a result of minimally invasive surgical intervention, a good clinical result was obtained in correcting the scoliotic deformity angle from 17.5°/16.0° [11°; 22°] to 4.6°/4.0° [1°; 7°]. Conclusion. The study showed the effectiveness of minimally invasive surgical treatment of degenerative scoliosis of the lumbar spine with short-segment fixation, which allowed obtaining satisfactory clinical results in 93 % of cases with a minimum number of complications (7 %).
