Method of Surgical Treatment of Spine Injury with the Use of Extracorporeal Navigation System Based on Additive Technologies

Abstract

We present a method of minimally invasive transcutaneous insertion of screws using a prefabricated extracorporeal navigation system using additive technologies (based on primary data obtained from the DICOM package in multi-detector computed tomography of the affected spine segment) according to the principle of personalized medicine. The method was tested on 10 dogs of different breeds with generally similar mechanism of trauma and typical consequences that led to fracture and dislocation of one of the lumbar vertebrae. In all animals, a positive treatment outcome of different degrees was achieved. Regression of the neurological deficit without significant postoperative inflammatory reaction was noted. The proposed method of treatment reduces the risk of malposition in pedicular and interbody pins and reduces radiation intraoperative exposure.
