The device description and performance studies focus on mechanical properties and structural components, with no mention of AI/ML or data processing.
Yes
The device is described as a spinal fixation system intended to promote fusion of the occipito-cervico-thoracic region of the spine for various medical conditions, indicating its use in treating and alleviating health conditions.
No
This device is a spinal fixation system, indicated for promoting fusion and providing stabilization in the spine. It is a surgical implant, not a tool used for diagnosing medical conditions.
No
The device description explicitly states that the system consists of various physical components such as screws, hooks, plates, rods, and connectors, all fabricated from medical grade titanium alloy. This indicates a hardware-based medical device, not a software-only one.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used for the surgical fixation and stabilization of the spine in skeletally mature patients. This is a therapeutic intervention performed directly on the patient's body.
- Device Description: The device is described as consisting of physical implants (screws, hooks, plates, rods, connectors) made of titanium alloy, designed to be surgically implanted.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (blood, tissue, etc.) outside of the body to provide information for diagnosis, monitoring, or screening.
IVD devices are used to perform tests on samples taken from the body, while this device is a surgical implant used to treat a condition within the body.

Device Description
The purpose of this 510(k) submission is to add a head-to-head cross connector and additional longitudinal rods and polyaxial pedicle screws. The modified system has the same intended use and fundamental scientific technology as the previously-cleared system.
Both the modified and predicate Lanx Posterior Cervicothoracic Spinal Fixation System consist of various screws, hooks, plates, rods, connectors, etc. that are used to build a construct to provide supplemental stabilization of spinal segments to support fusion. The system components can be assembled in a variety of configurations, with the anchors and connectors rigidly locked to the rod, allowing the surgeon to tailor the construct to the particular needs of the patient,
Both the modified and predicate Lanx Posterior Cervicothoracic Spinal Fixation System implants are fabricated from medical grade titanium alloy per ASTM F136. The modified Lanx Posterior Cervicothoracic Spinal Fixation System implants are manufactured using the same manufacturing processes, and are passivated and anodized in the same manner as the implants in the predicate Lanx Posterior Cervicothoracic Spinal Fixation System.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was conducted to characterize the modified Lanx Posterior Cervicothoracic Spinal Fixation System. Static and dynamic axial compression bending and static and dynamic torsion testing were performed in accordance ASTM F1717 on the modified and predicate systems, and the results compared. Also, axial grip and cantilever bending testing was performed in accordance with ASTM F1798 on the modified and predicate system, and the results compared. The modified device functioned as intended and the observed test results demonstrate substantial equivalence to a predicate device.

(a)
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.(b)

Device Description and Technological Characteristics
The purpose of this 510(k) submission is to add a head-to-head cross connector and additional longitudinal rods and polyaxial pedicle screws. The modified system has the same intended use and fundamental scientific technology as the previously-cleared system.
Both the modified and predicate Lanx Posterior Cervicothoracic Spinal Fixation System consist of various screws, hooks, plates, rods, connectors, etc. that are used to build a construct to provide supplemental stabilization of spinal segments to support fusion. The system components can be assembled in a variety of configurations, with the anchors and connectors rigidly locked to the rod, allowing the surgeon to tailor the construct to the particular needs of the patient,
Both the modified and predicate Lanx Posterior Cervicothoracic Spinal Fixation System implants are fabricated from medical grade titanium alloy per ASTM F136. The modified Lanx Posterior Cervicothoracic Spinal Fixation System implants are manufactured using the same manufacturing processes, and are passivated and anodized in the same manner as the implants in the predicate Lanx Posterior Cervicothoracic Spinal Fixation System.
Performance Data
Performance testing was conducted to characterize the modified Lanx Posterior Cervicothoracic Spinal Fixation System. Static and dynamic axial compression bending and static and dynamic torsion testing were performed in accordance ASTM F1717 on the modified and predicate systems, and the results compared. Also, axial grip and cantilever bending testing was performed in accordance with ASTM F1798 on the modified and predicate system, and the results compared. The modified device functioned as intended and the observed test results demonstrate substantial equivalence to a predicate device.
Substantial Equivalence
The modified Lanx Posterior Cervicothoracic Spinal Fixation System has the same intended use, indications, technological characteristics, and principles of operation as the predicate system. The modifications to the Lanx Posterior Cervicothoracic Spinal Fixation System do not raise new issues of safety or effectiveness. Also, mechanical testing demonstrated comparable mechanical properties to the predicate device. Thus, the modified Lanx Posterior Cervicothoracic Spinal Fixation System is substantially equivalent to the predicate device.
