The summary describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is described as providing "immobilization and stabilization of spinal segments as an adjunct to fusion" and is used in the treatment of various medical conditions like severe spondylolisthesis, fracture, scoliosis, and tumor, which aligns with the definition of a therapeutic device.
No
Explanation: The provided text describes a spinal fixation system intended for immobilization and stabilization of spinal segments as an adjunct to fusion. It details mechanical components and their uses for treatment, not for diagnosing conditions.
No
The device description explicitly states that the Lanx Spinal Fixation System consists of various physical components such as screws, hooks, rods, plates, and connectors, which are hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used in vivo (within the body) to provide mechanical support and stabilization to the spine during fusion. IVDs are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The device components (screws, hooks, rods, plates, connectors) are all physical implants designed for surgical use within the body.
- Anatomical Site: The device is used on the thoracic, lumbar, and sacral spine, which are internal anatomical structures.
- Lack of IVD Characteristics: There is no mention of analyzing biological specimens, using reagents, or providing diagnostic information based on laboratory tests.
This device is a surgical implant used for spinal fixation and fusion, which falls under the category of medical devices, but not specifically In Vitro Diagnostics.

§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when 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 (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). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:
“Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (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). The safety and effectiveness of these devices for any other conditions are unknown.”
“Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.”
(2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls:
(i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant.
(iii) Device components must be demonstrated to be biocompatible.
(iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(v) Labeling must include the following:
(A) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(B) Intended use and indications for use, including levels of fixation;
(C) Identification of magnetic resonance (MR) compatibility status;
(D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and
(E) Detailed instructions of each surgical step, including device removal.
(3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls:
(i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate.
(ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.

Technological Characteristics
The Lanx Spinal Fixation System consists of various screws, hooks, rods, plates, 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, allowing the surgeon to tailor the construct to the particular needs of the patient.
Performance Data
Performance testing and engineering analysis was performed and submitted to characterize the modified components of the system. The Lanx Spinal Fixation System functioned as intended and the observed test results demonstrate substantial equivalence to the predicate device.
Substantial Equivalence
The modified Lanx Spinal Fixation System is as safe and effective as the predicate device. The Lanx Spinal Fixation System has the same or similar intended use, indications, technological characteristics, and principles of operation as the predicate system. The minor differences in the modified components do not raise any new issues of safety or effectiveness. Mechanical testing also demonstrated comparable mechanical properties to the previously cleared Lanx Spinal Fixation System. Thus, the modified Lanx Spinal Fixation System is substantially equivalent to the predicate device.
