Intended Use

The Fixion Intramedullary Nail is intended for use in the fixation of long bone fractures, including diaphyseal fractures in the humerus, tibia and femur. It is indicated for shaft fractures 5cm below the surgical neck, and 5cm proximal to the distal end of the medullary canal.

Device Description

The Fixion Intramedullary Nailing System consist of the following main components:

  1. The Nail Implant is an expandable, sealed, stainless steel, cylindrical, ribbed rod without interlocking holes. The proximal end has a one-way valve for expansion. The nail is cap protected.
  2. The Insertion Handle is a device designed to be connected to the nail proximal end, and used for nail insertion. Its distal end has locking "teeth" to prevent relative rotation between the nail and the handle.
  3. The Inflation Device is a pump, which rotation of its handle delivers saline into the nail. The pump pressure gauge indicates the expansion pressure. This action causes the nail expansion and abutment to the bone medullary cavity.
    In addition the system consists of additional accessories including a removal adapter, a slide hammer and a slide hammer adapter and a screwdriver.
AI/ML Overview

Here's the analysis of the provided text regarding the acceptance criteria and study for the Fixion Intramedullary Nailing System:

This document is a 510(k) premarket notification for a medical device. FDA 510(k) clearances typically rely on demonstrating "substantial equivalence" to a legally marketed predicate device rather than conducting extensive clinical efficacy studies with predefined acceptance criteria and performance metrics against a robust ground truth, as would be common for AI/ML-based software. Therefore, many of the requested categories are not applicable to this type of submission.

The "acceptance criteria" here are primarily about meeting existing material and handling standards and demonstrating similarity to already-cleared devices.

2. Sample Size Used for the Test Set and Data Provenance

This information is not applicable to this 510(k) submission. There is no "test set" in the context of an algorithm or diagnostic performance evaluation described. The submission focuses on demonstrating compliance with material standards and substantial equivalence to existing devices.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

This information is not applicable. No ground truth for a test set (in the context of diagnostic accuracy or AI performance) was established or is relevant to this type of device submission.

4. Adjudication Method for the Test Set

This information is not applicable. No test set requiring expert adjudication is described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, and Effect Size

No, an MRMC comparative effectiveness study was not done. This is a physical medical device (intramedullary nail), not a diagnostic algorithm or AI-assisted system where human reader performance would be a relevant metric.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done

No, a standalone performance evaluation (as would be done for an algorithm) was not done. This device is a surgical implant, not a standalone algorithm.

7. The Type of Ground Truth Used

The primary "ground truth" for this submission would be:

  • Engineering Standards: Conformance to established ASTM and ISO standards for materials (e.g., 316L stainless steel meeting F138).
  • Predicate Device Characteristics: The characteristics (intended use, operating principles, design, materials, packaging, sterilization) of the previously cleared Fixion IM Nailing System (K990717, K003212, K003215, K010901) and Fixion Interlocking Proximal Femoral Intramedullary Nailing System (K010988, K012967). The new device's characteristics are compared against these known, legally marketed devices.

There is no "ground truth" related to disease pathology or patient outcomes in this particular 510(k) submission beyond the general safety and effectiveness implied by equivalence to predicate devices.

8. The Sample Size for the Training Set

This information is not applicable. There is no "training set" in the context of an algorithm or AI system for a physical medical device.

9. How the Ground Truth for the Training Set was Established

This information is not applicable. As there is no training set, there is no method for establishing its ground truth.
