TI  - Comparison of Operative Time and Blood Loss With the FFX(R) Device Versus Pedicle 
      Screw Fixation During Surgery for Lumbar Spinal Stenosis: A Retrospective Cohort 
      Study.

AB  - Background Pedicle screw (PS) placement can be associated with soft tissue damage 
      and blood loss. The study objective was to evaluate differences in operative time 
      and blood loss between PS fixation and an implantable facet fusion device in 
      patients undergoing lumbar fusion surgery. Materials and methods A retrospective 
      analysis was performed on patients undergoing lumbar fusion surgery with PS 
      fixation or the lumbar Facet FiXation (FFX) device. Procedures were performed by 
      the same surgeon at a single institution. The PS group included patients from 
      2016 and the FFX group included patients from 2018. Variables including age, sex, 
      levels operated on, operative time, and operative blood loss were collected. 
      Results A total of 70 patients were included in the study. Twenty-eight in the PS 
      arm and 42 in the FFX arm. The PS group had a mean age of 67.5 +/- 9.3 years 
      compared to 70.4 +/- 11.5 years for the FFX group. The PS group had a higher 
      percentage of females (57.1%) versus the FFX group (31.0%); p = 0.025. Mean 
      number of levels operated on were similar between the PS and FFX groups (2.3 +/- 1 
      .1 vs. 2.2 +/- 1.0, respectively; p = 0.89). Mean operative time was significantly 
      longer for the PS group versus the FFX group (152.5 +/- 39.4 vs. 99.4 +/- 44.0 
      minutes; p < 0.001). Mean operative blood loss was significantly greater for the 
      PS group versus the FFX group (446.5 +/- 272.0 vs. 251.0 +/- 315.9 mL; p < 0.01). 
      Differences were independent of the number of levels operated on. Conclusion 
      Placement of the FFX device is associated with a significant reduction in 
      operative time and blood loss compared to PS fixation in patients undergoing 
      spinal fusion surgery.
