Device Description

The VHS™ Pediatric Hip Screw System is a compression fixation system used for the treatment of femoral fractures. It consists of adjustable plates, lag screws, compression screws and bone screws. Materials: The devices are manufactured from 316 LVM or 22-13-5 stainless steel per ASTM standards. Function: The system functions to provide immediate stability and temporary fixation during the natural healing process following fractures of the distal femur.

AI/ML Overview

The provided text is a summary of a 510(k) premarket notification for the VHS™ Pediatric Hip Screw System. This document focuses on establishing substantial equivalence to existing devices, which is a regulatory pathway for medical devices. It does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria in the way a clinical or technical validation study would for an AI/ML device.

The 510(k) process for this type of medical device generally relies on demonstrating that the new device has the same intended use and technological characteristics as a predicate device, and that any differences do not raise new questions of safety or effectiveness. Performance data would typically involve mechanical testing to ensure material strength and functional integrity, but these specific details are not provided in this summary.

Therefore, I cannot fulfill your request for information related to acceptance criteria, a study proving the device meets them, sample sizes, expert involvement, or AI/ML specific evaluations (such as MRMC studies, standalone performance, or ground truth establishment for training data). This document is not the appropriate source for such information.

Dear Dr. Abendschein:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 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.

Regulation Number and Section

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
