Abstract
Objective. To perform a comparative radiological analysis of the methods of hybrid stabilization (posterior fixation in combination with cement vertebroplasty and osteoplasty with deproteinized allobone) and circular stabilization (posterior fixation in combination with anterior fusion) used in the treatment of uncomplicated burst fractures of the vertebral bodies associated with osteoporosis.Material and Methods. The study is retrospective. Two groups of patients were formed, and inclusion and exclusion criteria were determined. The magnitude of kyphosis correction (according to Cobb), the magnitude of residual postoperative kyphotic deformity, as well as its recurrence in the long-term postoperative period, and the sagittal balance (Barrey index) were assessed. The follow-up period was 12 months. Subjective assessments of the patient’s condition were not considered.Results. The magnitude of initial kyphotic deformity (>20°), incomplete achievement of kyphosis correction after surgery (> 5°), the value of densitometry T-score, and sagittal imbalance before and after surgical intervention are, with a statistically significant difference, the main predictors of local kyphosis recurrence, incomplete correction of deformity and decompensated sagittal imbalance.Conclusions. When comparing the methods of hybrid and circular stabilization, there was no statistical difference in radiological outcomes.
