Evaluation of the Efficacy and Safety of FFX Facet Cages Compared With Pedicle Screw Fixation in Patients With Lumbar Spinal Stenosis: A Long-Term Study.

Study Design: Hybrid retrospective/prospective study.

Objective: The study evaluated the long-term safety and efficacy of the FFX facet cage versus pedicle screw (PS) fixation in patients with lumbar spinal stenosis (LSS).

Summary Of Background Data: A previous single-arm study reported on the safety, fusion rate, and patient outcomes associated with the use of the FFX facet cage in patients with lumbar spinal stenosis.

Intracranial Solitary Fibrous Tumour Management: A French Multicentre Retrospective Study.

Background: Intracranial solitary fibrous tumour (iSFT) is an exceptional mesenchymal tumour with high recurrence rates. We aimed to analyse the clinical outcomes of newly diagnosed and recurrent iSFTs.

Methods: We carried out a French retrospective multicentre ( = 16) study of histologically proven iSFT cases.

Comparison of the Biomechanical Effect of the FFX Device Compared With Other Lumbar Fusion Devices: A Finite Element Study.

Background: Lumbar decompression can result in postsurgical instability and spondylolisthesis in patients with lumbar spinal stenosis (LSS). While pedicle screw (PS) constructs improve stability and support fusion, their use can lead to adjacent level degeneration due to rigidity and resultant overload of anatomical structures. The FFX device is a facet spacer designed to be a less invasive alternative for obtaining fusion compared with PS.

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

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.
