Cannulated Screw and Double Compression Cannulated Screw are intended for the treatment of fractures, and arthrodesis of bones with the appropriate screw size.

The Cannulated Compression Taper Screw (2.5-3.0 mm cannulated) are intended to be used as stand-alone bone screws for internal bone fixation for bone fractures, fusions, osteotomies and non-unions in the ankle, foot, hand, and wrist.

The Cannulated Compression Taper Screw (3.5 mm and larger, cannulated) are intended to be used as stand-alone bone screws for internal bone fixation for bone fractures, fusions, ostectomies and non-unions in the ankle, foot, hand, wrist, clavicle, scapula, olecranon, humerus, radius, ulna, tibia, calcaneus, femur, and fibula.

Cannulated Screws are implantable medical devices developed for application in osteosynthesis, with the purpose of reducing, compressing, aligning, stabilizing, and fixing different types of fractures, in small, medium, and large bones, of lower and upper limbs, and can be used in isolated form or associated with washers. This submission also includes the corresponding washers for Cannulated Screws.

The screws have a hexagonal connection for a wrench and can be found in three different models: Cannulated Screw, Double Compression Cannulated Screw and Cannulated Compression Taper Screw. These devices are found in a variety of diameters to meet the range of anatomies of the patients, are presented in Titanium Alloy according to the standard ASTM F136, being provided in non-sterile condition.

The provided text is a 510(k) Premarket Notification from the FDA regarding "Cannulated Screws." It details the device's indications for use, technological characteristics, and performance data. However, this document does not contain information about an AI/ML-driven medical device, a study involving human readers or expert ground truth, or an AI algorithm's performance.

The "Performance Data" section discusses mechanical properties testing of the physical screws (torsional properties, driving torque, axial pullout strength, chemical and mechanical properties) against ASTM standards. It concludes that the device presents safety and efficacy in terms of its mechanical properties, but this pertains to the physical product, not a diagnostic or AI-assisted system.

Therefore, I cannot provide the requested information regarding acceptance criteria and study details for an AI-driven device, as the provided document does not pertain to such a device.

The Cannulated Screws Neoortho are generally intended for fracture fixation of various bones and bone fragments, such as femoral neck, intercondylar femoral, malleolus, pilon tibial, calcaneus, talus, tibial plateau, tarsal, metatarsal, wrist, metacarpal, carpal, scaphoid and radius fracture. The Cannulated Screws Neoortho are also intended for fixation arthrodesis, iliosacral dislocations, and hallux valgus corrections. Accessories implants: The washer is used to increase bone contact area for distributing the forces/load and prevent the screw head from sinking into the bone.

The Neoortho Cannulated Screws include nine cannulated screw specifications and associated washers, which are manufactured from stainless steel and titanium alloy. The cannulated screw is a self-tapping screw with a cancellous or cortical thread that can be guided into a position via a guided wire. They are used to aid in the alignment and stabilization of fractures to the skeletal system.

The technological characteristic of the Neoortho Cannulated Screws are similar to the predicate devices including design, dimensions, and materials. The Neoortho cannulated screws and washers are fabricated from stainless steel per ASTM F138 and Ti-6Al-4V alloy per ASTM F136. The stainless steel and Ti-6Al-4V are commonly used material in orthopedic implants.

The provided text describes a 510(k) premarket notification for "Cannulated Screws Neoortho" and details the non-clinical tests performed to demonstrate substantial equivalence to predicate devices. It does not contain information about an AI device or details relating to acceptance criteria and studies typically associated with AI/ML medical devices. The document focuses on mechanical and sterilization properties for an orthopedic implant.

Therefore, I cannot provide an answer based on the prompt's request for AI device acceptance criteria, performance, and study details like sample size for test/training sets, expert qualifications, or MRMC studies.
