On Unsatisfactory Outcomesof Transpedicular Fixation

Objective. The analysis of structure and frequency of unsatisfactory outcomes occurring after transpedicular spinal fusion. Material and Methods. The results of spinal fusion with internal transpedicular constructions in 96 patients with uncomplicated fractures in the lower thoracic and lumbar spine were assessed. Results. The following unsatisfactory outcomes were revealed within 1 to 5 years after surgery: breakage of rods – 9 cases, surface soft tissue inflammation – 3, screw misplacement outside anatomical landmarks – 2, kyphotic deformity, changing spinal axis in sagittal plane – 2, preservation of preoperative vertebral wedging after removal of the construction – 7 cases. Сonclusion. Complex systemic prevention of unsatisfactory outcomes and optimization of preoperative stage allow improving treatment results in patients with uncomplicated fractures of lower thoracic and lumbar vertebra.
