Intended Use

The Arthrex Spine Compression FT Screws are intended to stabilize the spine as an aid to fusion through immobilization of the facet joints, either through bilateral transfacet fixation, or unilateral transfacet fixation when used contralateral to pedicle screw fixation. The Arthrex Spine Compression FT Screws are intended to be used with or without bone graft, at a single or multiple levels, from C2 to S1, for treatment of any or all of the following: pseudoarthrosis and failed previous fusions which are symptomatic or which may cause secondary instability or deformity; spondylolisthesis; spondylolysis; degenerative disc disease (DDD) as defined by neck and/or back pain of discogenic origin as confirmed by radiographic studies; degeneration of the facets with instability and trauma including spinal fractures and/or dislocations. The Arthrex Spine Compression FT Screw is also indicated for fracture fixation of small bones and bone fragments including pars interarticularis and odontoid. The fracture fixation of pars interarticularis is indicated for the adult and adolescent population (12 to 21 years of age).

Device Story

Arthrex Spine Compression FT Screws are headless, threaded, cannulated titanium implants. Designed for spinal stabilization and small bone fracture fixation. Screws feature variable-stepped thread pitch to provide compression and stability between bony fragments or joints. Used by surgeons in clinical settings for spinal fusion procedures or fracture repair. Output is mechanical fixation of bone segments. Benefits include stabilization of spinal segments or bone fragments to facilitate healing and fusion.

Clinical Evidence

Bench testing only. Performance evaluated via axial push-out and static cantilever bending per ASTM F2193. MR safety and compatibility assessed per ASTM F2182-19 and ASTM F2119-13, including displacement force, torque, RF heating, and image artifacts. Clinical literature summary provided to support expanded indications.

Technological Characteristics

Headless, threaded, cannulated titanium implants. Variable-stepped thread pitch. Mechanical fixation. Testing performed per ASTM F2193 (spinal screws), ASTM F2182-19 (RF heating), and ASTM F2119-13 (MR artifacts).

Indications for Use

Indicated for spinal stabilization as an aid to fusion (C2-S1) via facet joint immobilization (bilateral or unilateral with pedicle screws) for pseudoarthrosis, failed fusions, spondylolisthesis, spondylolysis, degenerative disc disease, facet degeneration, and trauma. Also indicated for fracture fixation of small bones/fragments, including pars interarticularis (adults and adolescents 12-21 years) and odontoid.

The screws have a fully threaded screw shaft with a tapering head and a variable-stepped thread pitch that allows the screw the ability to provide compression and stability between bony fragments or joints. | | Indications for Use | The Arthrex Spine Compression FT Screws are intended to stabilize the spine as an aid to fusion through immobilization of the facet joints, either through bilateral transfacet fixation, or unilateral transfacet fixation when used contralateral to pedicle screw fixation.

The fracture fixation of | Page 1 of 3 {5} Arthrex K250920 - Page 2 of 3 | | pars interarticularis is indicated for the adult and adolescent population (12 to 21 years of age). | | --- | --- | | **Performance Data** | Arthrex conducted axial push-out and static cantilever bending in accordance with in conformance with the FDA currently recognized version of ASTM F2193 Standard Specifications and Test Methods for Components Used in the Surgical Fixation of the Spinal Skeletal System-Annex 4: Test Method for Measuring the static and fatigue bending strength of metallic spinal screws on the subject Arthrex Spine Compression FT Screws to demonstrate performance is substantially equivalent to the predicate devices. Arthrex has conducted the recommended non-clinical testing per the FDA Guidance, “Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment”, which includes magnetically induced displacement force, magnetically induced torque, heating by RF fields, and image artifact (set up and parameters may not be the same). In addition, Arthrex has performed in vivo electromagnetic simulation to further establish the safety and compatibility of the system in MR environment. The maximum mass of the Arthrex Spine Compression FT Screw is less than that of the worst-case construct previously tested of the Arthrex Compression FT Screw family. Therefore, the system does not represent a new worst-case in terms of MR compatibility compared to the modeled implants for force, torque, and image artifact testing. Radio frequency induced heating was evaluated using ASTM F2182-19 Test Method for Measurement of Radio Frequency Induced Heating near Passive Implants during Magnetic Resonance Imaging and Guidance for FDA, Assessment of Radiofrequency-Induced Heating in the Magnetic Resonance (MR) Environment for Multi-Configuration Passive Medical Devices. Image artifact was evaluated using ASTM F2119-13, Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants. A clinical literature summary was provided to support the expansion of indications. The subject Arthrex Spine Compression FT Screw device testing performance characteristics, fall within the scope of FDA’s Facet Screw Systems – Performance Criteria for Safety and Performance Based Pathway Guidance for Industry and Food and Drug Administration Staff Document issued on April 13, 2022. | | **Technological Comparison** | The Arthrex Spine Compression FT Screw System has the same intended use/indications, fundamental scientific technology, materials, sterility, and packaging method as the predicates | Page 2 of 3 {6} Arthrex K250920 - Page 3 of 3 | | Corridor Fixation System (K192744) and Arthrex Compression FT Screw (K201132, K182361, K170382, K150456, K132217) devices. | | --- | --- | | **Conclusion** | Based on the intended use, fundamental scientific technology, and the data provided in this Traditional 510(k), Arthrex has determined that the Arthrex Spine Compression FT Screws are substantially equivalent to the predicate device. Any differences between the proposed and predicate device are considered minor and do not raise different questions concerning safety and effectiveness. | Page 3 of 3
