COMPUTER 3D-MODELING OF PATIENT-SPECIFIC NAVIGATIONAL TEMPLATE FOR CERVICAL SCREW INSERTION

Objective. To prove the effectiveness of 3D computer modeling and printing of patient-specific templates for cervical spine screw fixation. Materials and Methods . Based on the MSCT data of three patients, 3D models of cervical vertebrae and guiding templates were produced. The screws were inserted transpedicularly into 3D-printed models of C 2 –C 7 vertebrae and C 1 lateral masses using standard cervical instrumentation. This technology was...
