The intended use of the associated manual surgical instruments is to aid in the implantation of the 4.5mm Facet Compression Device. ## Device Story The Disposable Posterior Lumbar Stabilization Procedure Kit provides a 4.5mm double-helix facet screw with a compression-locking collar and self-retaining washer, alongside manual surgical instruments. The device is used by surgeons in an operating room setting to stabilize the spine as an aid to fusion. The screw is inserted posteriorly through the superior side of the facet, across the facet joint, and into the pedicle to achieve bilateral immobilization. The kit is provided sterile via gamma radiation, while a reusable compression tool is provided non-sterile for on-site steam autoclave sterilization. The device provides mechanical stabilization to the spine, potentially benefiting patients by facilitating fusion in cases of instability or degenerative conditions. ## Clinical Evidence Bench testing only. Performance test results indicate the device is safe and satisfies functional and performance requirements for its intended use. ## Technological Characteristics Titanium alloy (ASTM F-136). Double-helix screw design with compression-locking collar and self-retaining washer. 4.5mm diameter; 30-40mm length range. Manual surgical instruments included. Sterilization: Gamma radiation (kit); moist heat/steam autoclave (reusable tool). ## Predicate Devices - BONE-LOK® 4.5mm Facet Screw and BONE-LOK® FS Instrument Kit ([K043351](/device/K043351.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

It is available as 4.5mm diameter device and is obtainable in a 30-40mm length range. Disposable surgical instruments for use in implanting the device are {1}------------------------------------------------ also included in the kit. The kit is provided "STERILE"; sterilization is by gamma radiation. The re-usable Compression Tool is provided separately in a "NONSTERILE" condition; sterilization is by moist heat (steam autoclaye) and is performed on-site. #### INDICTIONS FOR USE The 4.5mm Facet Compression Device with Washer, which is included in the Disposable Posterior Lumbar Stabilization Procedure Kit, is indicated for spondylolisthesis. spondylolysis, degenerative disc disease (DDD) as defined by back pain of discogenic origin as confirmed by radiographic studies, degeneration of the facets with instability and fracture, pseudoarthrosis or failed previous fusion. ## INTENDED USE The intended use of the 4.5mm Facet Compression Device contained in the Disposable Posterior Lumbar Stabilization Disposable Kit is 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. The intended use of the associated manual surgical instruments is to aid in the implantation of the 4.5mm Facet Compression Device. # TECHNOLOGICAL CHARACTERISTICS The 4.5mm Facet Compression Device contained in the Disposable Posterior Lumbar Stabilization Procedure Kit is identical to the previously cleared BONE-LOK® 4.5mm Facet Screw. The manual surgical instruments are substantially equivalent to the instruments cleared as the BONE-LOK® FS Instrument Kit. ## BIOCOMPATIBILITY AND PERFORMANCE DATA The 4.5mm Facet Compression Device is made of a titanium alloy, which meets the requirements of ASTM F-136. The materials for the devices as well as the instruments are identical to materials used in a myriad of legally marketed orthopedic spinal fixation devices and instruments. Performance test results indicate that the device is safe and satisfies functional and performance requirements when used as indicated. The associated instruments have also met functional and performance requirements. ## CONCLUSIONS DRAWN FROM STUDIES Test results demonstrate that the devices contained in the Disposable Posterior Lumbar Stabilization Procedure Kit is substantially equivalent to the predicate devices and are capable of safely and effectively performing the stated intended use. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
