APTUS Hand Scaphoid Plates are indicated for fractures and non-unions of the scaphoid.

The purpose of this submission is to obtain marketing clearance for an additional device design to expand the range of the Medartis APTUS® Hand Plates, previously cleared under K102537.
The subject device APTUS Hand Scaphoid Plates is available in three designs - small, standard, large - all with 6 screw holes. All plates have anatomical designs that are appropriate for the scaphoid. The subject device plates are compatible with screws and k-wires previously cleared in K102537, K051567, K232144 (for srews), K092038, K202589 and K232144 (for k-wires).
The subject device plates are manufactured from unalloyed titanium conforming to ASTM F67, and are provided non-sterile and sterile.

This document is a 510(k) Premarket Notification from the FDA regarding the "APTUS Hand Scaphoid Plates." It outlines the regulatory review and states that the device is substantially equivalent to legally marketed predicate devices.

However, the provided text does not contain any information about acceptance criteria or a study that proves the device meets specific performance criteria related to an AI/Software as a Medical Device (SaMD) product.

Instead, this document pertains to a physical medical device (bone fixation plates) and references mechanical testing to demonstrate performance and substantial equivalence to predicate devices, not AI performance.

Therefore, I cannot fulfill your request as the required information (acceptance criteria for an AI/SaMD product, details of an AI performance study, number of experts, ground truth establishment, etc.) is absent from the provided text.

The document explicitly states: "Clinical data were not provided in this submission." and refers to "Mechanical fatigue and static testing" as the non-clinical testing performed.

To complete your request, I would need a regulatory submission document for an AI/SaMD product that discusses its performance characteristics, acceptance criteria, and the study conducted to demonstrate its capabilities.

Ask a specific question about this device

The Acumed Hand Plating System is intended for the management of fractures, fusions, and osteotomies of the distal, middle, and proximal phalanges and metacarpals and other bones of appropriate size for the devices.

The Hand Plating System consists of plates, locking screws, lag screws, and k-wires. Plates are available in a variety of shapes to accommodate varying fracture patterns and/or patient anatomy. The plates come in thicknesses of 0.8 mm to 1.3 mm. The locking screws and lag screws have major thread diameters of 1.5 mm to 2.3 mm, provided in lengths ranging from 5 mm to 20 mm. The lag screws and k-wires are used for fixation independent of the plates. The plates are made of titanium per ASTM F-67. The screws, lag screws, and the k-wires are made of titanium alloy per ASTM F136. All plates and screws are provided sterile and non-sterile.

The provided text describes a 510(k) submission for the Acumed Hand Plating System, which is a medical device for orthopedic fixation. It does not describe the acceptance criteria or a study proving the device meets those criteria in the context of an AI/algorithm-based device.

The document explicitly states: "The non-clinical testing enclosed in this submission includes static and cyclic performance testing and engineering analysis." This refers to mechanical and engineering tests, not studies related to algorithm performance or human-in-the-loop improvements.

Therefore, for your request regarding AI/algorithm acceptance criteria and studies, the provided text does not contain the necessary information. It is a traditional medical device submission focused on substantial equivalence to existing predicate devices based on design, materials, and mechanical performance.
