Percutaneous pedicle screw/rod fixation

Abstract

Percutaneous instrumented posterior fixation with pedicle screws and rods is frequently used. The insertion of the percutaneous pedicle screws is identical among the various platforms, whereas insertion of the rod can be done in three different ways, depending on the system utilized. The target entry point is at the junction of the lateral facet and the transverse process (or ala, for S1). We prefer to use beveled Jamshidi needles, since they provide better directional insertion.
