The device is indicated for posterior surgical treatment of any or all of the following at the L1 to S1 (inclusive) spinal levels: Spondylolisthesis, Pseudoarthrosis or failed previous fusions which are symptomatic; Degenerative Disc Disease (DDD) as defined by back pain of discogenic origin with degeneration of disc confirmed by history and radiographic studies and/or degenerative disease of the facets with instability. ## Device Story Resolute Facet Screw System provides bilateral transfacet fixation for lumbar spine stabilization. System consists of single-use, non-sterile, cannulated titanium alloy screws in fully or partially threaded designs. Used by surgeons in posterior spinal procedures to aid fusion at L1-S1 levels. Device functions as mechanical fixation hardware; no software or electronic components. Clinical benefit derived from stabilizing spinal segments in patients with degenerative conditions or failed prior fusions. ## Clinical Evidence Bench testing only. No clinical data provided. Substantial equivalence supported by cantilever testing and engineering analysis. ## Technological Characteristics Titanium alloy (6AL-4v-ELI per ASTM F136). Cannulated, single-use, non-sterile screws. Fully and partially threaded designs. Mechanical fixation device; no energy source, software, or connectivity. ## Predicate Devices - Spineology® Capture™ Facet Screw System ([K092464](/device/K092464.md)) - NuVasive® Triad® Facet Screw System ([K020411](/device/K020411.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
