Intended Use
The VERTEBRON PSS™ Pedicle Screw System is intended for noncervical, nonpedicle fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion in skeletally mature patients. The VERTEBRON PSS™ Pedicle Screw System is intended for non cervical pedicle fixation for the following indications: spondylolisthesis (Grade 3 and 4 at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment); trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion in skeletally mature patients.
Device Description
The VERTEBRON PSS™ Pedicle Screw System is comprised of non-sterile, single use, titanium alloy components. The VERTEBRON PSS™ Pedicle Screw System attaches to the vertebral body by means of screws to the non-cervical spinal and allows a surgeon to build a spinal implant construct. This system's design is intended to stabilize the spinal operative site during the fusion process of a bone graft in the disc space. The VERTEBRON PSS™ Pedicle Screw System is made up of rods, multi-axial and standard screws, hooks and locking caps. This submission adds both adjustable and fixed cross connectors.
More Information

No
The summary describes a mechanical spinal implant system and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is intended to stabilize the spinal operative site during the fusion process for various conditions such as degenerative disc disease, spondylolisthesis, trauma, and spinal stenosis. This directly treats or alleviates a disease/condition.

No

The VERTEBRON PSS™ Pedicle Screw System is described as a system for pedicle fixation and stabilization of the spinal operative site during the fusion process, which indicates it is a therapeutic or reconstructive device, not a diagnostic one.

No

The device description explicitly states it is comprised of "non-sterile, single use, titanium alloy components" such as rods, screws, hooks, and locking caps, which are physical hardware components.

Based on the provided information, the VERTEBRON PSS™ Pedicle Screw System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body. The description of the VERTEBRON PSS™ Pedicle Screw System clearly states it is comprised of components that "attaches to the vertebral body by means of screws to the non-cervical spinal" and is used to "stabilize the spinal operative site during the fusion process of a bone graft". This is a surgical implant, not a device that analyzes biological samples.
  • The intended use and device description focus on surgical intervention and stabilization of the spine. There is no mention of analyzing blood, urine, tissue, or any other bodily fluid or substance.

Therefore, the VERTEBRON PSS™ Pedicle Screw 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.
