Device Description

The Echo Bi-Metric Microplasty Femoral Stem is a monolithic, collarless, straight stem designed to reduce hip pain for patients and restore joint biomechanics and stability. The femoral stem is designed to fit patient femoral anatomies for primary or revision hip arthroplasties. The stems are manufactured from Ti-6Al-4V per ASTM F136/ASTM F620 and feature a proximal circumferential porous plasma spray (PPS) coating for biological fixation per ASTM F1580.

Patient contacting, reusable implant specific instruments are manufactured from stainless steel and include an aluminum titanium nitride (AlTiN) PVD or titanium nitride (TiN) PVD coating.

AI/ML Overview

This document is a 510(k) premarket notification from the FDA regarding the Biomet Echo Bi-Metric Microplasty Line Extension, a hip joint prosthesis. The document does not contain information about acceptance criteria or a study proving the device meets them in the context of an AI/medical device performance evaluation as you've requested.

Here's why and what's present instead:

Type of Device: This is a physical orthopedic implant (hip prosthesis), not an AI-powered diagnostic or assistive device.
Regulatory Context: The FDA clearance is for "substantial equivalence" to existing legally marketed predicate devices, meaning it's demonstrated to be as safe and effective as devices already on the market. This is a common pathway for physical medical devices.
Performance Data: The "Summary of Performance Data" refers to mechanical tests performed on the physical implant (e.g., fatigue testing, range of motion analysis) to demonstrate its physical integrity and performance, not a study evaluating diagnostic accuracy or AI algorithm performance.

Therefore, your request for:

A table of acceptance criteria and the reported device performance: Not applicable in the AI context. The document mentions mechanical test standards like ISO 7206-6, ISO 7206-4, and ISO 21535, where the "performance" is that the device passes these mechanical tests, demonstrating its durability and function as an implant.
Sample size used for the test set and the data provenance: Not applicable. There's no test set of patient data for AI evaluation.
Number of experts used to establish the ground truth for the test set and the qualifications: Not applicable. No ground truth for an AI algorithm.
Adjudication method: Not applicable.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done: Not applicable.
If a standalone performance (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
The type of ground truth used: Not applicable.
The sample size for the training set: Not applicable.
How the ground truth for the training set was established: Not applicable.

In summary, the provided document details the FDA clearance for a physical hip implant based on its mechanical performance and substantial equivalence to existing devices, not the performance of an AI model.

Dear Ms. Amy Walriven:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

Regulation Number and Section

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
Classification. Class II.
