Properly used, in the presence of adequate immobilization, absorbable SmartNail™ is intended for use in the fixation of fragments of fractured non-load bearing bones, osteotomies and arthrodeses, for example in the fixation of apical fragments, osteochondral fragments and cancellous/non-load bearing fragments. The SmartNail™ includes an arthroscopic applicator set. The arthroscopic applicator set consists of Handle, Tip, Piston, House, Wrench, Drill bit and K-wires.

The SmartNail™ is not intended for use in and is contraindicated for: 1) Fractures and osteotomies of cortical bone (except cortical bones of the foot and the hand), 2) Fractures and osteotomies in weight bearing cancellous bone, 3) Situations where internal fixation is otherwise contraindicated, e.g., active or potential infection and where patient co-operation cannot be guaranteed (e.g. alcoholism), 4) Treatment of physeal fractures in children, because the effect of SmartNail™ upon the healing of growth plate has not been tested clinically.

Device Description

The SmartNail™ is provided with a diameter of 1.5 mm and lengths of 16, 20 and 25 mm. 5 barbs, placed at intervals of 1.5 mm on two sides of the SmartNail™, prevent the implanted SmartNail™ from slipping out. The SmartNail™ is made of polylactide homopolymer and polylactide copolymer materials with strength retention time 20-50 weeks.

AI/ML Overview

This 510(k) summary (K993074) for the Bionx Implants Inc. SmartNail™ does not contain information about acceptance criteria or a study demonstrating device performance against such criteria.

The provided document is a 510(k) premarket notification for a medical device. This type of submission focuses on demonstrating "substantial equivalence" to a legally marketed predicate device, rather than proving a device meets specific performance acceptance criteria through clinical or analytical studies in the way an AI/ML device submission would.

Here's why the requested information is not present and what the document does provide:

Type of Device: The SmartNail™ is an "Absorbable Bone Fixation Nail," a physical implant, not a software-as-a-medical-device (SaMD) or an AI/ML diagnostic tool. Therefore, the usual metrics like sensitivity, specificity, AUC, or reader studies are not applicable.
Purpose of 510(k): The primary goal of a 510(k) is to show that a new device is as safe and effective as a predicate device, as stated in the "Substantial Equivalence" section. This is typically achieved by comparing design, materials, manufacturing processes, intended use, and sometimes non-clinical performance data (e.g., mechanical strength, degradation properties) to the predicate.
"Study that proves the device meets the acceptance criteria": For a physical implant like the SmartNail™, this would typically involve biocompatibility testing, mechanical testing (e.g., tensile strength, bending strength), and potentially animal studies or limited human clinical data to support safety and performance. However, these are generally presented as justification for substantial equivalence, not as a direct "performance study" with a defined acceptance criterion table in the summary. The summary mentions "strength retention time 20-50 weeks," which relates to performance, but no comparative data or acceptance criteria are provided in this specific document excerpt.

Therefore, I cannot populate the table or answer the specific questions related to acceptance criteria, sample sizes, experts, adjudication, MRMC studies, or ground truth as these concepts are not addressed in this 510(k) summary for a physical implant.

The provided document details the following:

Dear Mrs. Annala:

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.

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.
