Intended Use

The APTUS Foot System 2.8-3.5 is indicated for use in fractures, osteotomies and arthrodesis of the tarsals, metatarsals and phalanges.

Device Description

The subject device sterile screws consist of sterile TriLock screws (locking), Cortical and Cancellous screws (non-locking). The APTUS TriLock Screws, Cortical Screws and Cancellous Screws that are compatible with the subject device plate are manufactured from titanium alloy conforming to ASTM F136. The APTUS K-Wires that are compatible with the subject device plates are manufactured from stainless steel conforming to ASTM F138 Standard Specification for Wrought 18Chromium-14Nickel-2.5Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673). The device-specific instruments (templates) are manufactured from unalloyed titanium, Grade 4, conforming to ASTM F67 Standard Specification for Unalloyed Titanium for Surgical Implant Applications (UNSR50250, UNS R50400, UNS R50550, UNS R50700).

The subject device Medartis APTUS Foot System 2.8-3.5 consisting of following plates and systems: 2.8 TriLock Plate Straight, 2.8 TriLock Plate Hole T Extended and 2.8 TriLock TMT-1 Medial Fusion Plates Large, APTUS Mid- and Hindfoot System 2.8/3.5 and Fusion System 3.5. The APTUS Mid- and Hindfoot System 2.8/3.5 includes TriLock 2.8 C Plates, 2.8 TriLock Calcaneus LCL Plates, 3.5 TriLock Calcaneus LCL Plates and 3.5 TriLock Calcaneus Step Plates. The subject device also includes sterile wedges that are used to support fixation of an opening wedge osteotomy. The wedges are stabilized by corresponding wedge screws that are placed through a plate. The subject device wedges are provided in two size series. The APTUS Fusion System 3.5 includes 3.5 TriLock Wing Plates, 3.5 TriLock Butterfly Plates, 3.5 TriLock TNC Fusion Plates, 3.5 TriLock NCM Fusion Plates, 3.5 TriLock TNCM Fusion Plates, 3.5 TriLock Talonavicular Fusion Plates. Furthermore, 3.5 TriLock Medial Column Fusion Plates, 3.5 TriLock Distal Medial Column Fusion Plates, 3.5 TriLock Proximal Column Fusion Plates. The APTUS Fusion System 3.5 plates include screw holes designed to accommodate appropriately sized bone screws and K-wires presently marketed as part of the APTUS System. The 2.8 TriLock Straight Plates are generic straight plates and used with 2.8 mm screws. The 2.8 TriLock Plate Hole T Extended are generic T plates and used with 2.8 mm screws. The 2.8 TriLock TMT-1 Medial Fusion Plates Large plates have anatomical designs that are appropriate for either the left or the right foot. The subject device plates are manufactured from unalloyed titanium, Grade 4, conforming to ASTM F67 Standard Specification for Unalloyed Titanium for Surgical Implant Applications (UNSR50250, UNS R50400, UNS R50550, UNS R50700). The subject device sterile screws consist of sterile TriLock screws (locking), Cortical and Cancellous screws (non-locking).

AI/ML Overview

The provided text describes the regulatory filing for the APTUS Foot System 2.8-3.5 and does not contain information related to a study proving the device meets acceptance criteria for an AI/software-based medical device. Instead, it details the substantial equivalence determination for a physical orthopedic implant system.

Therefore, I cannot extract the information required for acceptance criteria and study data for an AI/software device from this document.

The document states: "The mechanical test results show that the acceptance criteria were met. Clinical data were not provided in this submission." This indicates that mechanical testing was performed for the physical device components, but no clinical data (which might involve an AI component) was submitted.

As such, all the specific points requested (sample size, data provenance, expert ground truth, adjudication, MRMC study, standalone performance, ground truth type, training set size, training set ground truth) are not applicable to the provided text.

§ 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)
