The subject device is indicated for posterior surgical treatment of any or all of the following at the L1 to S1 (inclusive) spinal levels including: 1) Trauma, including spinal fractures and/or dislocations; 2) Spondylolisthesis; 3) Spondylolysis; 4) Pseudoarthrosis or failed previous fusions which are symptomatic or which may cause secondary instability or deformity; 5) Degenerative diseases which include: (a) degenerative disc disease (DDD) as defined by neck and/or back pain of discogenic origin as confirmed by patient history with degeneration of the disc as confirmed by radiographic studies and/or (b) degenerative disease of the facets with pain and/or instability on plain flexion and extension lateral radiographs where there is movement of the vertebral bodies relative to each other of more than 4mm. ## Device Story CHAMELEON™ Fixation System provides bilateral, transfacet spinal fixation to aid fusion. Device consists of partially threaded 4.5mm diameter titanium (Ti6Al4V) screws (30-50mm lengths) and optional angulating washers to increase load-bearing surface area. Used in posterior lumbar spine surgery (L1-S1) by surgeons to stabilize vertebral segments. Screws are non-sterile; require steam autoclave sterilization by healthcare facility prior to use. Provides mechanical stabilization to address instability from trauma or degenerative conditions. ## Clinical Evidence Bench testing only. Mechanical performance evaluated per ASTM F-2003 and ASTM F-543 standards. No clinical data provided. ## Technological Characteristics Material: Titanium alloy (Ti6Al4V) per ASTM F-136. Design: Partially threaded 4.5mm diameter screws (30-50mm lengths) with optional angulating washers. Energy: None (mechanical). Sterilization: Steam autoclave (user-performed). ## Predicate Devices - Depuy Discovery ([K012773](/device/K012773.md)) - Nuvasive Inc. - Townley Transfacet Screw ([K994308](/device/K994308.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

CHAMELEON™ Fixation System is designed to provide bilateral, transfacet fixation of the spinal facet joint in the lumbar spine. The facet screw included in the CHAMELEON™ Fixation System is a partially threaded 4.5mm diameter screw offered in lengths of 30-50mm (in 5mm increments). The device is composed no mairal grade Titanium (Ti6Al4V) that complies with ASTM F-136. The devices are offered with in washer or without a washer. Washers: Integral to the screw design, washers 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 screws to provide optimal bony contact over a range of screw trajectories. The devices are sold non-sterile and are packaged in a clear poly bag. These devices are sterilized by a healthcare professional using Steam Autoclave in accordance to the instructions for use provided by SpineFrontier, Inc., as well as the instructions provided by the manufacturer of the Autoclave. #### Intended Use [21 CFR 807.92(a)(5)] The subject device is intended to stabilize the spine as an aid to fusion by transfacet fixation. The subject device is indicated for posterior surgical treatment of any or all of the following at the I.1 to SI (inclusive) spinal levels including: 1) Trauma, including spinal fractures and/or dislocations; 2) Spondylolisthesis; 3) Spondylolysis; 4) Pseudoarthrosis or failed previous fusions which are symptomatic or which may cause secondary instability or deformity; 5) Degenerative diseases which include: (a) degenerative disc disease (DDD) as defined by neck and/or back pain of discogenic origin as confirmed by patient history with degeneration of the disc as confirmed by radiographic studies and/or (b) degenerative disease of the facets with pain and/or instability on plain flexion and extension lateral radiographs where there is movement of the vertebral bodies relative to each other of more than 4mm. #### Technological Characteristics [21 CFR 807.92(a)(6)| The device is substantially equivalent to the predicate devices based on comparison on physical and performance characteristics. ### Performance Data |21 CFR 807.92(b)(1)| The device is composed of biocompatible materials that have a long successful history in the orthopedic industry. The device performed well during various mechanical tests including comparison to predicate devices. The device was tested using the following standards as guidance: ASTM F-2003 (Standard Specifications and Test Methods for Components Used in the Surgical Fixation of the Spinal Skeletal System) and ASTM F-543 (Standards Specifications and Test Methods for Metallic Bone Screws). #### Conclusion [21 CFR 807.92(b)(3)| We believe that the subject device is substantially equivalent and as safe and effective as the predicate device. {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
