The 4.5mm BONE-LOK® PLS IMPLANT is indicated for spondylolisthesis, spondylolysis, degenerative disc disease (DDD) as defined by back pain of discogenic origin as confirmed by radiographic studies, degeneration of the facets with instability and fracture, pseudoarthrosis, or failed previous fusion.

The intended use of the 4.5mm BONE-LOK® PLS Implant is to stabilize the spine as an aid to fusion through bilateral immobilization of the facet joints. The 4.5mm BONE-LOK® PLS Implant may be used to supplement legally marketed anterior fusion products in order to create an anterior/posterior fixation construction as an aid to fusion. The screws are inserted posteriorly through the superior side of the facet, across the facet joint and into the pedicle. The 4.5mm BONE-LOK® PLS Implant is intended for lumbar bilateral facet fixation, with or without bone graft, at single or multiple levels from L1 to S1. The intended use of the associated manual surgical instruments is to aid in the implantation of the 4.5mm BONE-LOK® PLS Implant.

Device Description

The 4.5mm BONE-LOK® PLS Implant is a double-helix screw with a compressionlocking collar made of medical grade titanium alloy and is provided "STERILE". The Single use PERPOS™ PLS System contains the 4.5mm BONE-LOK® PLS Implant and disposable surgical instruments for use in implanting the device and is provided "STERILE". The re-usable Compression Tool is provided separately in a "NONSTERILE" condition; sterilization is by moist heat (steam autoclave) and is performed on-site.

AI/ML Overview

The provided text is a 510(k) summary for a medical device (Single Use PERPOS™ PLS System, BONE-LOK® PLS Implant). It describes the device, its intended use, and claims substantial equivalence to predicate devices.

However, the document does NOT contain any information regarding acceptance criteria, study details, or performance data of the device.

The document discusses:

Device Identification: Trade names, common names, classification, product codes.
Predicate Devices: Lists previously cleared devices to which the current device claims substantial equivalence.
Device Description: Materials and general characteristics of the implant and associated instruments.
Intended Use/Indications for Use: Specifies the medical conditions the implant is used for and its role in spinal fusion.
Technological Characteristics and Substantial Equivalence: Asserts that the device is similar to predicates in these aspects.
FDA Clearance Letter: Confirms the 510(k) clearance based on substantial equivalence.

Therefore, I cannot provide the requested information, which includes a table of acceptance criteria and device performance, sample sizes for test and training sets, data provenance, ground truth establishment, expert details, adjudication methods, or results of MRMC or standalone studies.

The 510(k) pathway for medical device clearance in the US primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than requiring extensive clinical trials or performance studies against predefined acceptance criteria for novel device functions. Performance data, if present, would typically be found in more detailed sections of the 510(k) submission, which are not included in this publicly available summary.

Dear Ms. Emerson:

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.
