Components include polyaxial screws, rods, hooks, and connectors. System provides immobilization and stabilization of spinal segments as an adjunct to fusion. Used in thoracic, lumbar, and sacral spine procedures. Surgeons implant components to treat instabilities or deformities. Mechanical testing confirms properties comparable to predicate. No software or algorithmic components. ## Clinical Evidence Bench testing only. No clinical data provided. ## Technological Characteristics Posterior pedicle fixation system. Components: polyaxial screws, rods, hooks, connectors. Materials: alloyed titanium and unalloyed titanium. Mechanical properties verified via bench testing. No software or electronic components. ## Regulatory Identification A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome. ## Predicate Devices - Lanx Spinal Fixation System ([K043484](/device/K043484.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Pedicle Screw Spinal System
21 CFR §888.3070 | Predicate Device Information K043484 Lanx Spinal Fixation System #### Predicate Device Identification The Lanx Spinal Fixation System is a posterior attachment pedicle fixation system. The system consists of a series of polyaxial screws, rods, cross connectors and interlocking mechanisms. The components are manufactured from alloyed titanium. ## Description of Device Modification This submission is intended to address a line extension to the Lanx Spinal Fixation System. The line extension includes additional pedicle screw sizes/configurations, hooks, connectors and the introduction of unalloyed titanium rods. #### Intended Use The Lanx Spinal Fixation System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis \\\DC - 071676/000630 - 1991386 v2 Page 1 of 2 {1}------------------------------------------------ # 1671633 (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). ## Statement of Technological Comparison The Lanx Deformity System has the same intended use and similar indications, principles of operation, and technological characteristics as the Lanx Spinal Fixation System. The minor differences in the line item extensions items do not raise any new questions of safety or effectiveness. Mechanical testing also demonstrated comparable mechanical properties to the predicate device.
