Cortical bone trajectory (CBT) screw is an attractive technique in terms of fixation strength and less invasiveness. However, the insertion of a pedicle screw penetrating cortical bone on the ideal trajectory is technically demanding. The use of 3-dimensional (3D) patient-matched guides may facilitate the use of this technique. In this technical note and case series, the use of a patient-matched 3D targeting guide for a circumferential fixation with CBT screws is described.

Abstract

Cortical bone trajectory (CBT) screw is an attractive technique in terms of fixation strength and less invasiveness. However, the insertion of a pedicle screw penetrating cortical bone on the ideal trajectory is technically demanding. The use of 3-dimensional (3D) patient-matched guides may facilitate the use of this technique. In this technical note and case series, the use of a patient-matched 3D targeting guide for a circumferential fixation with CBT screws is described.
