The 510(k) summary describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.
Yes.
The device is used to provide temporary stabilization until a solid spinal fusion develops for various spinal conditions, indicating a therapeutic purpose.
No
The device is a lumbar plate fixation system for temporary stabilization of the spine, not for diagnosing medical conditions.
No
The device description explicitly lists physical components (base plate, cover plate, bone screws), indicating it is a hardware device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Description: The Unity LX Anterolateral Lumbar Plate Fixation System is a physical implantable device consisting of plates, screws, and a cover plate. It is used for surgical fixation of the spine.
- Intended Use: The intended use is to provide temporary stabilization to the lumbar spine until fusion occurs. This is a surgical intervention, not a diagnostic test performed on a sample.
The information provided clearly describes a surgical implant used for structural support, not a device used for testing biological samples.

Intended Use / Indications for Use
The Unity LX™ Anterolateral Lumbar Plate Fixation System is indicated for use as an anteriorly or anterolaterally placed supplemental fixation device for the lumbar region of the spine (L1-L5) above the bifurcation of the vascular structures. When properly used, this system will help provide temporary stabilization until a solid spinal fusion develops. Specific indications include:
Degenerative disc disease (defined as back pain of discogenic origin with 1) degenerative disc confirmed by history and radiographic studies)
- 2) Pseudoarthrosis
-
- Spondylolysis
-
- Spondylolisthesis
-
- Fracture
-
- Neoplastic disease
-
- Unsuccessful previous fusion surgery
-
- Lordotic deformities of the spine
-
- Idiopathic thoracolumbar or lumbar scoliosis
-
Deformities (i.e., scoliosis, kyphosis, and/or lordosis) associated with deficient posterior elements such as that resulting from laminectomy, spina bifida, or mvelomenigocele
-
Neuromuscular deformity (i.e., scoliosis, lordosis, and/or kyphosis) associated with pelvic obliquity

§ 888.3060 Spinal intervertebral body fixation orthosis.
(a)
Identification. A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.(b)
Classification. Class II.

Substantial Equivalence
The Unity LX Anterolateral System, the Unity Anterior System and the Synthes ATB System have the same intended use and similar indications, technological characteristics and principles of operation. The only technological differences between the Unity LX Anterolateral Lumbar Fixation Plate and its predicates are minor dimensional characteristics and have been addressed with side-by-side mechanical verification testing. These differences do not present any new issues of safety or effectiveness, therefore, the Unity LX Anterolateral Lumbar Fixation Plate is substantially equivalent to its predicate devices.

Dear Mr. Sprunck:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA). it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA`s issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set
