An effectiveness using transpedicular fixation instrumentation for spine arthrodesis

Mykola Polishchuk, Eugene Slynko, Andriy Muravskiy


The objective of this research was to determine the efficacy and safety of an instrumentation device designed for transpedicular spinal fixation by evaluating fusion rates and clinical pain and function scores; to determine complication rates associated with the device; and to compare the obtained data with that previously published in the literature. Thirty-six consecutive patients were enrolled in this 3-year monitored investigation. The study population was derived from three diagnostic categories: tumour of spine, spondylolisthesis and degenerative disc disease, vertebral fracture. The data source consisted of radiographs, clinical examination. Patients were evaluated preoperatively, intraoperatively, and postoperatively at 3, 6 months. These data compare favourably to existing reports of spinal arthrodesis effected with other types of instrumentation and without device implantation. In a 3-year trial, the transpedicular fixation instrumentation produced successful spinal fusion in the majority of our patients, with acceptable complication rates.
