Abstract: Objective. To perform comparative analysis of posterior stabilization methods combined with cement vertebroplasty and osteoplasty with deproteinized bone allograft in the treatment of uncomplicated burst fractures of the vertebral bodies associated with osteoporosis. Material and Methods. The study was a retrospective analysis. Two groups of patients were formed, inclusion and exclusion criteria were determined. The follow-up period was 12 months. The magnitude of kyphosis correction according to the Cobb method, the magnitude of residual postoperative kyphotic deformity, its recurrence in the long term postoperative period, and the length of transpedicular fixation were assessed. Sagittal balance parameters and subjective assessments of the patient’s condition were not evaluated. Results. With a statistically significant difference, it can be said that the main predictors of recurrence of local kyphosis, incomplete correction of deformity and increased pain syndrome are the level of injury (T12 vertebra), the degree of initial kyphotic deformity, incomplete achievement of its correction after surgery (>10°), and the value of T-criterion according to densitometry. The length of fixation does not affect the loss of correction and recurrence of kyphosis, however it may correlate with the severity of osteoporosis. Conclusions. When comparing posterior stabilization methods in combination with cement vertebroplasty or osteoplasty, there was no statistical difference in clinical and radiological outcomes.
