No
The document describes a mechanical spinal fixation system and does not mention any software, image processing, or AI/ML capabilities.
Yes
The device is described as a "pedicle screw system indicated for the treatment of severe spondylolisthesis (Grades 3 and 4) of the L5-S1 vertebra" and also to "provide immobilization of spinal segments...as an adjunct to fusion in the treatment of...instabilities or deformities." This directly addresses the treatment of medical conditions and support for healing, classifying it as therapeutic.
No
The device is a spinal fixation system intended to stabilize and promote spinal fusion, which is a treatment, not a diagnostic process.
No
The device description explicitly states it is a "multiple component, posterior spinal fixation system consisting of polyaxial pedicle screws, rods (Straight and pre-bent) and setscrews," fabricated from titanium alloy. This clearly indicates a physical hardware device, not software.
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 surgical implant system used to stabilize the spine and promote fusion. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details physical components like screws, rods, and setscrews made of titanium alloy. This aligns with a surgical implant, not a device used to examine samples from the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other elements typically associated with in vitro diagnostics.
Therefore, the Mikron Spinal Fixation System is a surgical implant device, not an IVD.

§ 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.

These devices have the same intended use, technological characteristics and basic design as the proposed device. The only changes to Mikron Spinal Fixation System are new sizes and shapes added to the product span (i.e., addinq various sizes of screws, and different size and shapes (straight and pre-bent) of rods).
3.4 Device Description
The Proposed Device is a top-loading multiple component, posterior spinal fixation system consisting of polyaxial pedicle screws, rods (Straight and pre-bent) and setscrews. The Mikron Spinal Fixation System will allow surgeons to build a spinal implant construct to stabilize and promote spinal fusion. The Mikron Spinal Fixation System is supplied non-sterile, single use and fabricated from titanium alloy (Ti6Al4V-ELI) that conforms to ASTM F136.

They both have same top-loading interconnection mechanism with same setscrew. The design incorporates the same design features as the predicate over new lengths and diameters to create a complete range of sizes for the surgeon. The system is attached to the vertebral body by means of screws at the non-cervical spine.
3.6.3 Function
All subject devices have the same function, which is acting as a spinal implant construct to stabilize and promote spinal fusion.
3.6.4 Level of Attachment
Levels of fixation of the Proposed and the Predicate Devices are for the thoracic, lumbar and sacral spine.
