AI/ML Overview

The provided document describes the Auxein Brand Vertaux 5.5 mm Pedicle Screw System and its substantial equivalence to a predicate device (K091442, Medtronic Sofamor Danek, USA, CD HORIZON Spinal System). The acceptance criteria and the study proving the device meets these criteria are outlined primarily through a comparison with the predicate device and non-clinical testing.

Here's the breakdown:

1. Table of Acceptance Criteria and Reported Device Performance:

The acceptance criteria are implicitly defined by the equivalence to the predicate device and compliance with established performance and material standards. The device performance is reported as meeting these standards and being "equivalent" to the predicate.

The document describes non-clinical testing for the Auxein Brand Vertaux 5.5 mm Pedicle Screw System.

  • Sample Size for Test Set: Not explicitly stated as a number of devices or constructs. The testing refers to "Applicable standards" and "Relevant test results" for materials and "Static compression testing," "Static Torsional Testing," and "Fatigue Compression testing" as per ASTM F 1717-18 for performance. These standards typically involve specific numbers of specimens, but those numbers are not detailed in this submission.
  • Data Provenance: The testing was conducted for the Auxein Brand Vertaux 5.5 mm Pedicle Screw System to demonstrate compliance with ASTM standards. This is prospective testing performed for the purpose of this submission. The origin of the data is internal testing or outsourced testing to laboratories demonstrating compliance with the specified ASTM standards. No mention of country of origin for the test data specifically, beyond the company's location in India.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts:

This information is not applicable to this type of submission. This document describes a medical device (pedicle screw system) which is evaluated primarily through engineering and material testing standards, and comparison to existing predicate devices, rather than human expert interpretation of diagnostic images or clinical outcomes that would require ground truth establishment by experts.

The submission is a 510(k) for substantial equivalence, relying on:

  • Non-clinical mechanical and material testing.
  • Comparison of technological characteristics and intended use to a legally marketed predicate device.

4. Adjudication Method for the Test Set:

This information is not applicable as it's not a clinical study involving human interpretation or outcome assessment requiring adjudication. The "test set" here refers to the physical devices undergoing mechanical and material testing, which are evaluated against predefined pass/fail criteria from the ASTM standards.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not conducted or referenced in this document. This type of study is typically used for diagnostic devices that involve human interpretation (e.g., radiology AI tools). This submission is for an implantable surgical device evaluated by engineering standards, not diagnostic interpretative tasks.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance):

Not Applicable. This device is a pedicle screw system, not an algorithm or AI software. Therefore, there is no "standalone" algorithm performance to evaluate.

7. Type of Ground Truth Used:

The "ground truth" for the non-clinical testing is defined by the acceptance criteria and methodologies outlined in the referenced ASTM standards (ASTM F 136, ASTM F 899-12, ASTM F 1717-18). These standards define the parameters, test methods, and acceptable ranges or failure modes for the materials and mechanical performance of spinal implant constructs. For the comparative analysis, the "ground truth" is the characteristics of the predicate device (CD HORIZON Spinal System, K091442) to which substantial equivalence is claimed.

8. Sample Size for the Training Set:

Not Applicable. This submission is for a physical medical device (implantable pedicle screw system), not a software or AI device that requires a "training set."

9. How the Ground Truth for the Training Set Was Established:

Not Applicable. As no training set is involved for this type of medical device submission.

§ 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;
