SURGICAL CORRECTION OF ADULT IDIOPATHIC SCOLIOSIS IN PATIENTS OF YOUNG AND MIDDLE AGE

Objective.To evaluate the results of surgical correction of idiopathic scoliosis in patients aged 18-50 years, in terms of different age groups.Material and Methods.A total of 393 patients (348 women, 45 men) with idiopathic scoliosis were operated on during 1996-2015. In all cases, posterior correction of the deformity was performed using segmental third-generation instrumentation. The primary curve and structural countercurve were included in the fusion area. Hook fixation was performed in 298 cases, and hybrid (hooks and pedicle screws) in 95. The period of postoperative follow-up was 4.4 years on average. Analysis of immediate and long-term results was performed using X-ray and computer optical topography in three age groups (age at the time of surgery): 18 to 24 years (274 patients), 25 to 34 years (95 patients), 35 years and older (24 patients).Results.No statistically significant differences between age groups were revealed, both in initial parameters (magnitude of the primary curve, countercurve, and the apical vertebra rotation) and in surgical results (magnitude of correction, loss of correction and mobility). When interviewing patients with the SRS-24 questionnaire, the best results were obtained in the group of age 18-24, worse in the group of age 25-34, and even worse in the group of age over 35. Computer topography also revealed the absence of statistically significant difference between age groups.Conclusion.Surgical treatment of adult idiopathic scoliosis provides quite satisfactory results, especially in terms of improving the quality of life, that do not have significant differences when comparing three age groups within the age range exceeding 30 years.
