The PILLAR SA PTC is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels in the lumbar spine (L2-S1). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis at the involved levels. These patients may have had a previous non-fusion surgery at the involved level(s). The PILLAR SA PTC is intended for use with autograft comprised of cancellous and/or corticocancellous bone graft.

The PILLAR SA PTC is intended for use with the four titanium alloy screws provided with the device. If the physician chooses to use fewer than four of the provided screws, then supplemental fixation must be used to augment stability. As an example, the supplemental fixation system that may be used is the Firebird Spinal Fixation System.

Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the PILLAR SA PTC.

Device Description

The PILLAR SA PTC device is implanted in the intervertebral disc space and is intended to facilitate vertebral fusion by stabilizing adjacent vertebrae, maintaining disc height, and preventing the collapsing of one vertebrate onto another.

The PILLAR SA PTC is designed to be used as a standalone device, when implanted with accompanying stabilizing screws. The PILLAR SA PTC spacers are provided sterile.

AI/ML Overview

This document is a 510(k) summary for the PILLAR® SA PTC, an intervertebral body fusion device. It focuses on demonstrating substantial equivalence to predicate devices, rather than establishing acceptance criteria and proving performance through a study with a test set, ground truth, and expert adjudication as typically described for AI/ML device evaluations.

Therefore, many of the requested categories are not applicable or cannot be extracted from this document.

Here's a breakdown of what can and cannot be answered based on the provided text:

1. A table of acceptance criteria and the reported device performance

The document states that the performance of PILLAR SA PTC was assessed through various mechanical and material tests. It doesn't present explicit "acceptance criteria" in a numerical sense but rather aims to show that the device performs similarly to predicate devices and meets relevant ASTM standards.

Test Conducted	Reported Device Performance / Outcome
Axial Compression (ASTM F2077)	Demonstrated substantial equivalence to predicate devices.
Compression-Shear (ASTM F2077)	Demonstrated substantial equivalence to predicate devices.
Expulsion (draft standard 04.25.05.02)	Demonstrated substantial equivalence to predicate devices.
Subsidence (ASTM F2267)	Demonstrated substantial equivalence to predicate devices.
Tensile Strength (ASTM F1147)	Demonstrated substantial equivalence to predicate devices.
Shear (ASTM F1044 & ASTM F1160)	Demonstrated substantial equivalence to predicate devices.
Wear (ASTM F1877)	Demonstrated substantial equivalence to predicate devices.
TABER Abrasion (ASTM F1978)	Demonstrated substantial equivalence to predicate devices.
Characterization of Porous Titanium Endplates & Interface (ASTM F1854)	Performed (details not provided, implying satisfactory results).
Bacterial Endotoxin Testing (BET) (ANSI/AAMI ST-72:2011)	Endotoxin limit less than 20EU per device (confirms sterility and safety).

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the document. The "tests" described are primarily mechanical and material characterization, not clinical studies with patients or data sets in the typical sense of AI/ML evaluation.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable as the "ground truth" for mechanical properties would be derived from physical measurements and material specifications, not expert consensus on interpretations.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is a medical device for spinal fusion, not an AI/ML diagnostic or assistive tool for human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. The "device" is a physical implant.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the mechanical and material tests, the ground truth would be established by:

ASTM standards: Defined methodologies and acceptance ranges for mechanical properties (e.g., strength, wear).
Material specifications: Chemical composition, microstructure, and physical properties of the PEEK OPTIMA LT1 and Ti-6Al-4V as described by ASTM F-2026, ASTM F1580, or ASTM F136.
Sterility standards: Endotoxin limits as per ANSI/AAMI ST-72:2011.

8. The sample size for the training set

Not applicable. There is no "training set" in the context of this device's evaluation.

9. How the ground truth for the training set was established

Not applicable.

Device Description

The PILLAR SA PTC in a standalone intervertebral body implant that is comprised of a PEEK OPTIMA LT1 core material as described by ASTM F-2026, with two integrated porous titanium

{4}------------------------------------------------

alloy (Ti-6Al-4V) endplates as described by ASTM F1580 or ASTM F136. The PILLAR SA PTC device is implanted in the intervertebral disc space and is intended to facilitate vertebral fusion by stabilizing adjacent vertebrae, maintaining disc height, and preventing the collapsing of one vertebrate onto another.

The PILLAR SA PTC is designed to be used as a standalone device, when implanted with accompanying stabilizing screws. The PILLAR SA PTC spacers are provided sterile.

Intended Use / Indications for Use

The PILLAR SA PTC is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels in the lumbar spine (L2-S1). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis at the involved levels. These patients may have had a previous non-fusion surgery at the involved level(s). The PILLAR SA PTC Spacer System is intended for use with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft.

Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the PILLAR SA PTC.

Summary of the Technological Characteristics of the Device Compared to the Selected Predicate Devices

The technological characteristics of the PILLAR SA PTC are similar to the predicate devices in terms of design, dimensions, intended use, materials, and performance characteristics. There are no significant differences between the PILLAR SA PTC and the predicate devices which would adversely affect the use of the product.

Performance Data – Summary of Non-Clinical Test Conducted for Determination of Substantial Equivalence

The performance of PILLAR SA PTC was assessed for the following: axial compression (ASTM F2077), compression-shear (ASTM F2077), expulsion (draft standard 04.25.05.02), subsidence (ASTM F2267), tensile strength (ASTM F1147), shear (ASTM F1044 & ASTM F1160), wear (ASTM F1877) and TABER abrasion (ASTM F1978). PILLAR SA PTC also underwent characterization of the porous titanium (ASTM F1854) endplates and interface. In addition, bacterial endotoxin testing (BET) has been performed. BET as specified in ANSI/AAMI ST-72:2011 confirm an endotoxin limit less than 20EU per device.

Test results demonstrated that PILLAR SA PTC is substantially equivalent to the predicate devices FORZA PTC Spacer System (K152475), PILLAR SA PEEK Spacer System (K081849), and Stalif Midline II Ti (K150643).

{5}------------------------------------------------

Basis of Substantial Equivalence

The new PILLAR SA PTC has the same intended use and similar indications for use as the Stalif Midline II Ti (K150643) and FORZA PTC Spacer System (K15475), similar technological characteristics and design as the FORZA PTC Spacer System (K152475), PILLAR SA PEEK Spacer System (K081849), and Stalif Midline II Ti (K150643), same or similar materials as the FORZA PTC Spacer System (K152475) and the same principles of operation as FORZA PTC Spacer System (K152475), PILLAR SA PEEK Spacer System (K081849), and Stalif Midline II Ti (K150643).
