← Product Code MRW · K121850 # Typhoon(TM) Facet Screw Fixation System (K121850) _Choicespine, LP · MRW · Sep 20, 2012 · OR · SESE_ **Canonical URL:** https://fda.innolitics.com/device/K121850 ## Device Facts - **Applicant:** Choicespine, LP - **Product Code:** MRW - **Decision Date:** Sep 20, 2012 - **Decision:** SESE - **Submission Type:** Traditional - **Device Class:** Class U - **Review Panel:** OR - **Attributes:** Therapeutic ## Intended Use The Typhoon™ Facet Screw Fixation System is intended to stabilize the spine as an aid to fusion through bilateral immobilization of the facet joints, with or without bone graft, at single or multiple levels, from L1 to S1 inclusive. The Facet Screw Fixation System is indicated for treatment of any or all of the following: degenerative disc disease (DDD) as defined by neck and/or back pain of discogenic origin as confirmed by patient history and radiographic studies; degenerative disease of the facets with instability; Spondylolisthesis; Spondylolysis; Pseudoarthrosis and failed previous fusions which are symptomatic or which may cause secondary instability or deformity; and trauma, including spinal fractures and/or dislocations. For transfacet fixation, the Typhoon™ Facet Screw Fixation System screws are inserted posteriorly through the superior side of the facet, across the facet joint, and into the inferior pedicle. ## Device Story Typhoon™ Facet Screw Fixation System is a posterior spinal fixation implant set; consists of titanium alloy screws and washers. Used by surgeons in clinical settings to stabilize facet joints; facilitates spinal fusion. Screws are self-tapping (4.5mm and 5.5mm diameters); washers provide load-bearing surface and angulate to accommodate various trajectories. Implants are inserted posteriorly through the superior facet, across the joint, into the inferior pedicle. Provides mechanical stability to the spine; aids in fusion process for patients with degenerative conditions or trauma. ## Clinical Evidence Bench testing only. No clinical data provided. Mechanical performance validated via static bending, dynamic bending, static torsion, and axial pullout testing per ASTM F2193 and ASTM F543 standards. ## Technological Characteristics Implants: Titanium alloy (Ti6Al4V ELI) per ASTM F136. Instruments: 17-4 SS or 465 SS per ASTM F899/A564. Self-tapping screw design; 4.5mm and 5.5mm diameters; variable lengths (20-60mm). Includes angulating washers for load distribution. Mechanical fixation principle. ## Predicate Devices - Discovery™ Facet Screw System ([K012773](/device/K012773.md)) - Chameleon™ Fixation Screw System ([K071420](/device/K071420.md)) - Fixcet™ Spinal Facet Screw Fixation System ([K100154](/device/K100154.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The bone screws are designed to transfix the facet articular process in the spine to enhance spinal fusion and stability. The self-tapping screws are 4.5mm and 5.5mm in diameter. The 4.5mm screws are supplied in length ranging from 20mm to 60mm and the 5.5 mm screws range in length from 25mm to 60mm. Washers are available to increase the load bearing area of the screw in contact with the bone. These washers are designed to angulate about the head of the bone screw to provide optimal bony contact over a range of screw trajectories. {1}------------------------------------------------ ## Intended Use ર્દ્ર દ The Typhoon™ Facet Screw Fixation System is intended to stabilize the spine as an aid to fusion through bilateral immobilization of the facet joints, with or without bone graft, at single or multiple levels, from L1 to S1 inclusive. The Facet Screw Fixation System is indicated for treatment of any or all of the following: degenerative disc disease (DDD) as defined by neck and/or back pain of discogenic origin as confirmed by patient history and radiographic studies; degenerative disease of the facets with instability; Spondylolisthesis; Spondylolysis; Pseudoarthrosis and failed previous fusions which are symptomatic or which may cause secondary instability or deformity; and trauma, including spinal fractures and/or dislocations. For transfacet fixation, the Typhoon™ Facet Fixation System screws are inserted posteriorly through the superior side of the facet, across the facet joint, and into the inferior pedicle. #### Materials The Typhoon™ Facet Fixation System implants are manufactured from Titanium alloy (Ti6AI4V) per ASTM F-136. All instrument parts that come in contact with human tissue are made from either 17-4 SS per ASTM F899 or 465 SS per ASTM F899/A564. ## Substantial Equivalence Documentation was provided that demonstrate the Typhoon™ Facet Screw Fixation System to be substantially equivalent to previously cleared device systems. The substantial equivalence is based upon equivalence in intended use, indications, anatomic location, material, and performance. Mechanical testing was performed according to ASTM F2193 "Standard Specification and Test Method for Components used in the Surgical Fixation of the Spinal Skeletal System" and ASTM F543 "Standard Specifications and Test Metallic Bone Screws". Testing parameters executed were static bending, dynamic bending, static torsion, and axial pullout. {2}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the seal of the Department of Health & Human Services (HHS) of the United States of America.
