Can the Interspinous Device, SPIRE (TM), be an Alternative Fixation Modality in Posterior Lumbar Fusion Instead of Pedicle Screw?

摘要

AIM: Although conventional posterior lumbar interbody fusion (PLIF) using pedicle screws provides successful outcomes, pedicle screw related complications are sometimes noted. SPIRE (TM) was invented as an interspinous fixation device (ISD) to replace pedicle screw. The aim of this study is to evaluate the clinical and radiological outcomes in patients who underwent unilateral PLIF using SPIRE (TM) compared with a pedicle screw.
