POSTERIOR SPONDYLOSYNDESIS IN THE TREATMENT OF IDIOPATHIC THORACIC SCOLIOSIS

Abstract

Background. The distribution of idiopathic scoliosis is quite large and ranges from 50 to 80 % among all spinal deformities. Materials and methods. Preoperative clinical and radiological data and data 5 years after surgery in patients with idiopathic thoracic scoliosis operated on with the use of posterior transpedicular fixation and posterior fusion were analyzed. 179 patients (154 women, 25 men) aged from 10 to 25 years old (mean age is 16.1 years old) were examined and operated, divided into 2 two groups. Group I with mobile deformities included 72 patients (69:3), in whom only the main curvature arc was included in the area of posterior spondylosyndesis and fixation. Group II with rigid arches included 107 patients (85:22) with a more extensive spondylosyndesis zone. The average degree of correction was 78 % (from 45 to 98 %). Results. There were no statistically significant demographic or perioperative indicators between the groups, except for the average number of levels of posterior spondylosyndesis (group I: 9.6 (from 4 to 13), group II: 11.5 (from 8 to 15); p 25 ° (calculated from functional radiographs), the zone of fixation and posterior spondylosyndesis was extended by two or three spinal motion segments in the caudal direction to ensure sagittal and frontal balance.
