The Savannah Lumbar Percutaneous Stabilization System (SLPSS) is intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the lumbar and/or sacral spine, specifically as follows:

When used as a pedicle screw fixation system of the posterior lumbar spine in skeletally mature patients, the SLPSS is indicated for one or more of the following: (1) degenerative spondylolisthesis with objective evidence of neurologic impairment. (2) fracture, (3) dislocation, (4) spinal tumor, and/or (5) failed previous fusion (pseudarthrosis).

In addition, when used as a pedicle screw fixation system, the SLPSS is indicated for skeletally mature patients: (a) having severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (L5-S1) vertebral joint; (b) who are receiving fusions using autogenous bone graft only; (c) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (d) who are having the device removed after the development of a solid fusion mass.

The Savannah Lumbar Percutaneous Stabilization System (SLPSS) is also intended to provide immobilization and stabilization of the spinal segments of the 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.

Device Description

The Savannah Lumbar Percutaneous Stabilization System is comprised of a variety of pedicle screws sizes, couplers, a ball swivel, rods and locking nuts that can be uniquely fitted for each individual case. All implantable components are manufactured from medical grade titanium alloy (Ti6Al4V-Eli).

AI/ML Overview

The provided text is a 510(k) summary for the Savannah Lumbar Percutaneous Stabilization System (SLPSS). It describes the device, its indications for use, and how it demonstrates substantial equivalence to predicate devices. However, the document does not contain information about acceptance criteria or a study that specifically proves the device meets such criteria.

Instead, the document states:

"The pre-clinical testing performed indicated that the Savannah Lumbar Percutaneous Stabilization System is substantially equivalent to predicate devices."

This implies that the device's performance was compared to existing, legally marketed devices (predicates) rather than against specific, predefined acceptance criteria through a standalone clinical or performance study with detailed metrics. The regulatory pathway chosen, a 510(k), relies on demonstrating "substantial equivalence" to a predicate device, which often involves comparing technical characteristics and performance data to show that the new device is as safe and effective as the predicate.

Therefore, for your request, the following information is largely not present in the provided text:

A table of acceptance criteria and the reported device performance: No specific acceptance criteria or performance metrics are listed.
Sample size used for the test set and the data provenance: Not mentioned.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not mentioned.
Adjudication method for the test set: Not mentioned.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs. without AI assistance: Not applicable, as this is a surgical implant, not an AI-assisted diagnostic device.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable for a surgical implant.
The type of ground truth used: Not applicable, as it's not a diagnostic device.
The sample size for the training set: Not mentioned.
How the ground truth for the training set was established: Not mentioned.

Summary of available information:

Device Name: Savannah Lumbar Percutaneous Stabilization System (SLPSS)
Regulatory Pathway: 510(k) Premarket Notification (K072116)
Claim of Performance: "The pre-clinical testing performed indicated that the Savannah Lumbar Percutaneous Stabilization System is substantially equivalent to predicate devices."
Predicate Devices Listed:
- Synthes USS Pedicle Screw System (K022949, K010108, K010658, K994121, K982987)
- DePuy Moss Miami Spinal System (K022623, K983583, K964024, K955348, K933881)
- U&I Optima Spinal System (K031585)
- Stryker Spine Xia Spinal System (K001319, K984251, K951725)
Nature of Testing: "Pre-clinical testing" was performed to demonstrate substantial equivalence, but details of this testing (e.g., in-vitro, mechanical, benchtop) are not provided in this summary.

Conclusion:

The provided document relies on showing substantial equivalence to predicate devices based on pre-clinical testing, rather than presenting a study with specific acceptance criteria as you've requested for a device that might involve diagnostic performance or AI. Therefore, most of the detailed information you are seeking is not available in this 510(k) summary.

Dear Dr. Jansen:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
