The AOS Trochanteric Nail is intended to treat stable and unstable proximal fractures of the femur including pertrochanteric, intertrochanteric and high subtrochanteric fractures and combinations of these fractures. The long trochanteric nail is additionally indicated for subtrochanteric fractures, pertochanteric fractures associated with shaft fractures, pathologic fractures (including prophylactic use) in osteoporotic bone of the trochanteric and diaphyseal areas, long subtrochanteric fracture, insilateral femoral fractures, proximal and distal non-unions and malunions and revisions procedures.

Device Description

The AOS Trochanteric Nail is femoral intramedullary nail that is design to enter through the greater trochanter. It consists of an intramedullary nail, sliding lag screw, anti-rotation screws and end cap. The Trochanteric Nail is a cannulated nail with proximal diameter of 15mm. The short Trochanteric Nails are18cm in length and the long Trochanteric Nails are 30cm, 36cm and 42cm in length. The nails are produced in diameters of 9mm, and 11mm. The proximal end of the nail has two holes; one to accept the 11mm lag screw and one to accept the optional 5.0mm anti-rotation screw. There are two nail configurations with the proximal holes angled at 125° or 130°. The proximal holes in the long nails having 10° of anteversion and are in a left and a right configuration. The proximal end of the nail is threaded to accept an end can. The distal end of the nail contains one cross locking hole and one cross locking slot. The distal hole and the slot are design to accept 5.0mm screws.

AI/ML Overview

The provided text is a 510(k) summary for the AOS Trochanteric Nail, an intramedullary fixation rod for treating femoral fractures. This document focuses on demonstrating substantial equivalence to previously marketed devices rather than presenting a study with acceptance criteria and device performance metrics in the way a clinical trial for a diagnostic device would.

Therefore, the requested information components related to acceptance criteria, device performance, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, and ground truth for training sets are not applicable (N/A) in this context.

This 510(k) summary is for a Class II medical device (intramedullary fixation rod) and relies on demonstrating an equivalence to legally marketed predicate devices, not on a performance study against specific acceptance criteria.

Summary of available information:

A table of acceptance criteria and the reported device performance:
- N/A. The document is a 510(k) summary for a medical device seeking market clearance based on substantial equivalence, not a performance study with explicit acceptance criteria. The "performance" is implicitly demonstrated through comparison to predicate devices' design and intended use.
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- N/A. No test set or clinical data is presented for performance evaluation in this 510(k) summary.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
- N/A. No ground truth establishment by experts is mentioned, as there is no specific performance study.
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- N/A. No adjudication method is mentioned, as there is no specific performance study.
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- N/A. This device is a physical implant (intramedullary nail), not an AI-powered diagnostic tool, so an MRMC study is irrelevant.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- N/A. This is a physical medical device, not an algorithm.
The type of ground truth used (expert concensus, pathology, outcomes data, etc):
- N/A. No performance study necessitating ground truth is presented.
The sample size for the training set:
- N/A. Not a machine learning or AI device.
How the ground truth for the training set was established:
- N/A. Not a machine learning or AI device.

Key information from the document that is relevant:

Device Name: AOS Trochanteric Nail
