The Hammerdesis™ Interphalangeal Fusion System is intended to stabilize and aid in the fixation of fractures, fusions, and osteotomies of the phalanges.
The Hammerdesis™ Interphalangeal Fusion system is composed of a counter rotation ring implant, recovery dowel and K-wire to be used in conjunction with a peg and hole fusion of the phalanges. The implant comes in two different sizes to accommodate differing anatomies. The counter rotation ring has axial spikes that prevent either side of the joint from rotating and allow fusion of the joint.
The provided text is a 510(k) summary for the Hammerdesis™ Interphalangeal Fusion System, a medical device. This document focuses on demonstrating the substantial equivalence of the device to existing predicate devices, primarily through mechanical performance testing.
It does not contain information about an AI/ML-driven device or diagnostic study. Therefore, I cannot provide a response addressing acceptance criteria and study details related to AI/ML device performance, such as sample sizes for test/training sets, expert ground truth establishment, MRMC studies, or standalone algorithm performance.
The document describes the device, its indications for use, technological characteristics, and performance data related to its mechanical properties. The performance data section states:
"The subject Hammerdesis™ Interphalangeal Fusion System was evaluated in static torsion test, static and dynamic cantilever bend testing, and axial pullout. The subject device demonstrated superior performance in comparison to that of the predicate (K131459); therefore, the subject device mechanical performance is considered substantially equivalent to the predicate (K131459)."
This indicates that the acceptance criteria for this device are based on its mechanical equivalence or superiority to the specified predicate device in these specific tests, rather than diagnostic accuracy metrics.
To answer your request, the provided document would need to be about a diagnostic AI/ML device, which it is not.
§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
