Device Description

The Lorenz Titanium Fracture / Rexastructive Devices are comprised of a variety of titanium fracture and reconstruction plates and screws with shapes and sizes designed for neassion of modition of marco on a varior of manum natures. The screws have both cross drive and canter dive head features, lag sames and as males will includes will includes straight, angle, double angle, and crescent, options with various lengths and thickness.

The Lorenz Titanium Fracture / Reconstructive Pre-Bent Plates are comprised of a specific range of existing plates. The plate is pre-shaped based on a CT Scan provided by the Surgeon specifically for a certain patient.

The Pro-batt plates may, in special cases, be attached to our Temporary Add-on Condyle (cleared under K002790). In these cases, the package inserts for both the Temporary Add-on Condyle will be included with the product. The poduct of the postkage insert for the Temporay Add-on Condyle is specific in identifying that on only indicated for temporary reconstruction and is not intended to a permanent implant

AI/ML Overview

This document is a 510(k) summary for the Walter Lorenz Surgical Mandibular Fracture/Reconstruction Devices and Pre-bent Plates. It does not describe a study that uses acceptance criteria and reports on device performance in the way requested by the prompt for an AI/CADe device. Instead, it details the substantial equivalence of the new device to previously cleared predicate devices.

Therefore, I cannot extract the requested information (acceptance criteria table, sample sizes, expert qualifications, adjudication methods, MRMC study details, standalone performance, ground truth types, or training set details) because this document does not pertain to the validation of an AI/CADe system. It is a regulatory submission for a physical surgical device.

Lorenz Titanium Fracture / Reconstruction Devices and Pre-bent Plates

Intended Use: The Lorenz Titanium Fracture / Reconstructive Devices and Pre-bent Plates are intended for use in the stabilization and fixation of mandibular fractures and mandibular reconstructive surgical procedures.

Contraindications:

Device Name:

  • Active infection. 1.
  • Foreign body sensitivity. Where material sensitivity is suspected, testing is to be completed prior to implantation. 2.
    1. Patients with limited blood supply, insufficient quantity of bone, or latent infection.
  • Patients with mental or neurologic conditions who are unvilling or incept macht mecallering postoperative care instructions. 1. If used in mandbular resertion cases, the mandibular reconstructive devices must be supported using a graft. If mandibular reconstructive devices are not supported by a graft, the devices can be expected to fracture, bend, brouk por fail.

Description: The Lorenz Titanium Fracture / Rexastructive Devices are comprised of a variety of titanium fracture and reconstruction plates and screws with shapes and sizes designed for neassion of modition of marco on a varior of manum natures. The screws have both cross drive and canter dive head features, lag sames and as males will includes will includes straight, angle, double angle, and crescent, options with various lengths and thickness.

The poduct of the postkage insert for the Temporay Add-on Condyle is specific in identifying that on only indicated for temporary reconstruction and is not intended to a permanent implant

Sterility Information: The places and screws will be marketed as non-sterile, single use devices.

Possible risks:

    1. Poor bone formation, Osteoporosis, Osteonyelitis, inhibited revasularization, or infection can cause loosening, bending one ing one fracture of the device.
    1. Nonunion or delayed union, which may lead to breakage of the implant.
    1. Migration, bending, fracture or loosening of the implant.
    1. Metal sensitivity, or allergic reaction to a foreign body.
    1. Decrease in bone density due to stress shielding.
    1. Pain, discomfort, abnormal sensation, or palpability due to the presence of the device.
    1. Increased fibrous tissue response around the fracture site and/or the implant.
    1. Necrosis of bone.
    1. Inadequate healing.
  • 10.Mandibular devices can fracture, bend, break or fail if used to bridge a mandibular resection site, in the absence of a graft.

Dear Ms. Reed:

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 (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115.
