Synopsis:

The use of transfacet pedicle screws is a method for posterior fixation. Bilateral transfacet screws provided better immediate stability than equivalent-sized unilateral or a bilateral standard pedicle screws at L5-S1.

ABSTRACT

Objective: There is a resurgence in facet screw use; however, there is a paucity of data comparing the stability of transfacet pedicle screws (TFPS) to standard pedicle screw-rod constructs at L5-S1. The authors aim to compare the stabilizing potential of TFPS compared to pedicle screws of the same length and diameter at L5-S1 with an intact native disc.
