Transitioning Lumbar Fusions to Outpatient Using Midline Less Exposure Surgery Techniques with Transfacet and Mediolateral Cortical Bone Pedicle Screws

Synopsis: 
The combined approach of unilateral pedicle screws plus contralateral facet screw has equivalent outcomes to bilateral traditional pedicle screw. This study demonstrates the feasibility of an alternative of posterior fixation.

ABSTRACT

Objective: Posterior decompression and fusion have been the standard of treatment for degenerative disc disease as well as disc herniation. Recent advances in medicine and healthcare have shown a trend to move surgeries to the outpatient setting. The authors aim to assess the outcomes of unilateral cortical pedicle screw-rod construct combined with a contralateral transfacet pedicle screw (TFPS) in the outpatient setting.

Biomechanical Comparison of Same Size Transfacet Screws Versus Pedicle Screws Across the L5-S1 Native Disc

Issue: 
DOI: 
10.7727/wimj.2017.029
Pages: 
416–23
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.
