Patient-Specific Templates for Pedicle Screw Insertion in Spinal Fixation Surgery

4 pages•Published: August 17, 2017

Abstract

The increased use of pedicle screws in scoliosis creates a challenge for accurate and safe placement of
screw within the pedicle during the scoliosis surgery. Patient-specific templates (PST) is a novel
method to guide the surgeons for allocating and detecting the positions and trajectories of pedicle
screws in scoliosis surgery. Based on CT-scans and according to certain protocol, this technique will
allow the surgeon to construct a 3D model of spine and present the stage and vertebrae which contain
the most deformed bone. With preplanned surgery on specific software, we can develop an accurate
and safe position of pedicle screws and its trajectories. This method has the ability to customize the
placement and the size of each pedicle screw based on the unique morphology and landmarks of the
vertebrae.

Keyphrases: patient specific templates, pedicle screws, scoliosis, spine
