Idiopathic scolioosis: long-term results of treatment of patients with the method of transpedicular fixation. Retrospective longitudinal study

Abstract

BACKGROUND: Тhe study of the treatment results of patients with idiopathic scoliosis should include both objective assessment methods, such as radiography and multispiral computed tomography, and subjective methods related to the response of the patient or his/her parents to treatment. A set of indicators will only allow an objective assessment of the long-term treatment outcomes.
 AIM: To examine long-term treatment results of posterior transpedicular fixation in patients with idiopathic scoliosis of varying severity.
 MATERIALS AND METHODS: Long-term treatment results by posterior transpedicular fixation were studied in 300 patients with idiopathic scoliosis of varying severity. To assess the effectiveness of treatment, clinical and radiological diagnostic methods and SRS30 and SRS22 questionnaires were used.
 RESULTS: Treatment results in 1 year were studied in all patients and in 2 years in 225 patients (75%). In 150 patients (50%), the long-term treatment results was studied in 5, and in 15 of them (10%) in 1012 years. The achieved correction value was maintained with a slight loss depending on the magnitude of the initial deformity and correction achieved after the operation. The SRS22 questionnaire 2 years after treatment of grade II deformity (according to Chaklin) showed that the indicators of postoperative function and remained practically unchanged, and the scores on self-esteem, appearance, and attitude were higher (p 0.05). In grade IV deformity, the scores on the appearance and attitude of others were high without significant differences.
 CONCLUSION: Dorsal correction of the spine using transpedicular implants in patients with idiopathic scoliosis allows obtaining good treatment outcomes, which was confirmed by the preservation of correction during dynamic X-ray examination and assessment using the SRS22 questionnaire.
