    Intended Use

    The Akros Scruture Anchor LisFranc Repair Kit is intended as an adjunct in fracture repair involving metaphyseal and periarticular small bone fragments where screws are not indicated, and as an adjunct in external fixation systems involving plates, with fracture braces and casting. Specifically, the Akros Scruture Anchor LisFranc Repair Kit is intended to provide fixation during the healing process following Tarasometatarsal (TMT) injury, such as fixation of foot soft tissue separations due to a Lisfranc injury (Midfoot Reconstruction).

    Device Description

    The Akros Scruture Anchor Lisfranc Repair Kit is a multiple-anchor orthopedic fixation device system, offered in both a stainless steel and a titanium version. The system is designed as an adjunct in repair of unstable joints, specifically as a means to provide fixation between the bones of the midfoot during the healing process following a Lisfranc injury. The design of the implant permits placement through any fracture repair plate that can accept a 4.0mm cortical screw conforming to ASTM F543-13. The anchors are provided pre-threaded and pre-loaded on their installation tools in a one-time-use pre-sterilized kit, with the Kirschner wire and drill bit needed for site preparation included.

    AI/ML Overview

    The provided document is a 510(k) premarket notification letter and summary for a medical device called the "Akros Scruture Anchor LisFranc Repair Kit."

    Based on the content of the document, the device described is a metallic bone fixation appliance, not an Artificial Intelligence/Machine Learning (AI/ML) enabled device. Therefore, the information typically required for an AI/ML device's acceptance criteria and study proving its performance (such as ROC curves, sensitivity/specificity, sample sizes for AI model training/testing, expert ground truth establishment, etc.) is not present in this document.

    The document focuses on the substantial equivalence of this physical implant device to a predicate device, primarily through non-clinical testing (e.g., mechanical testing, biocompatibility).

    Here's what can be extracted, acknowledging the nature of the device:

    1. A table of acceptance criteria and the reported device performance

    The document does not provide a table with quantitative acceptance criteria and reported device performance in the manner expected for an AI/ML device (e.g., sensitivity, specificity, AUC). Instead, it states that:

    Acceptance Criteria Category (for physical device)Reported Device Performance (Summary)
    Mechanical Performance Testing (e.g., pull-to-failure, load-to-failure, torque, fatigue, fretting, pitting corrosion)"The results of these tests indicate that the performance of the Scruture Anchor device is adequate for its intended use." Data was adopted from a reference device due to design similarity.
    Biocompatibility (e.g., cytotoxicity, pyrogenicity, bacterial endotoxin)"Results demonstrated that the reference device meets an endotoxin limit of
