   EXPANDABLE INDICATIONS
   The Biomet Side Access Distal Femoral Expandable offers a treatment option for patients requiring distal femoral replacement who have not yet achieved full skeletal maturity (open epiphysis) or patients who require surgery who have significant residual leg length discrepancy. Indication for use of this device is most commonly tumor resection but could also involve osteoarthritis; rheumatoid arthritis; correction of deformity; and correction or revision of unsuccessful osteotomy, arthrodesis or previous joint replacement.
   The devices are single use implants intended for implantation with bone cement or with Biomet Compress.

The new devices included in this submission are additional components to Biomet's Orthopaedic Salvage System (OSS) that offer surgeons additional prostheses options to be used in limb salvage reconstruction. The new devices include proximal femoral components and tibial components.

The provided text describes a 510(k) premarket notification for the Biomet Orthopaedic Salvage System (OSS™) and related components. This document focuses on demonstrating substantial equivalence to previously marketed predicate devices, primarily through non-clinical testing. As such, it does not contain the kind of detailed information about acceptance criteria for a device's performance, human reader studies, or training/test set specifics that would typically be found in an AI/ML device submission.

Therefore, many of the requested fields cannot be filled from this document. However, based on the information available, here's what can be provided and what cannot:

1. A table of acceptance criteria and the reported device performance

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the document. The testing described is non-clinical (mechanical and material characterization), not involving human patient data or a "test set" in the context of AI/ML evaluation.

3. 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)

This information is not applicable/provided for this non-clinical submission. Ground truth determination by experts is not relevant to the mechanical and material testing described.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable/provided for this non-clinical submission. Adjudication methods are typically used for establishing ground truth in clinical evaluations, which were not performed here.

5. 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

This information is not applicable/provided. This submission is for a physical orthopedic implant, not an AI/ML diagnostic or assistive device that would involve human readers.

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

This information is not applicable/provided. This submission is for a physical orthopedic implant, not an AI/ML algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

This information is not applicable/provided. The "ground truth" for the non-clinical tests would be established engineering standards, material properties specifications, and mechanical performance requirements, rather than clinical ground truth types listed.

8. The sample size for the training set

This information is not applicable/provided. There is no AI/ML training set involved in this submission.

9. How the ground truth for the training set was established

This information is not applicable/provided. There is no AI/ML training set involved in this submission.

Summary of the Study:

The studies conducted for the Biomet Orthopaedic Salvage System (OSS™) - Proximal Femoral & Hybrid Tibial were non-clinical performance tests aimed at demonstrating the device's substantial equivalence to existing predicate devices.

The studies included:

• Device Fatigue Testing: Performed on proximal femoral and hybrid tibial components.
• Range-of-Motion (ROM) Analysis: Likely assessed the mechanical range of motion of the components.
• Material Characterization: Specifically for the OsseoTi™ material, confirming it is identical to previously cleared materials.

The conclusion of these non-clinical tests was that "the devices performed within the intended use, did not raise any new safety and efficacy issues and were found to be substantially equivalent to the predicate devices." No clinical testing was deemed necessary for this determination.

I am sorry, but the provided text does not contain the level of detail required to answer your request regarding acceptance criteria and study information for a medical device. The document is a 510(k) summary for a medical device (Biomet Orthopaedic Salvage System (OSS) Line Extension) indicating substantial equivalence to predicate devices, but it does not include:

1. A table of acceptance criteria and reported device performance: The document lists "Device Fatigue Testing", "Device Static Disassociation Testing", "Tensile Properties Testing", and "Material Characterization for OsseoTi" as performed tests, but does not provide specific acceptance criteria or the numerical results of these tests.
2. Sample sizes used for the test set and data provenance: No information on sample sizes (N) for any of the non-clinical tests is given.
3. Number of experts used to establish ground truth and their qualifications: This is not applicable as no clinical study for ground truth establishment is mentioned.
4. Adjudication method: Not applicable.
5. Multi-reader multi-case (MRMC) comparative effectiveness study: The document explicitly states "No clinical testing was necessary for a determination of substantial equivalence." and "Clinical Performance Data/Information: N/A". Therefore, no MRMC study was conducted.
6. Standalone performance (algorithm only without human-in-the-loop performance): This is not applicable as the device is a physical orthopedic implant system, not a software algorithm.
7. Type of ground truth used: Not applicable as no clinical study requiring ground truth was conducted.
8. Sample size for the training set: Not applicable as this relates to AI/machine learning models, and the device is a physical implant.
9. How the ground truth for the training set was established: Not applicable for the same reason as above.

The document primarily focuses on demonstrating substantial equivalence to existing predicate devices based on non-clinical performance testing and material characterization, without the need for new clinical studies to establish safety and effectiveness for a novel performance claim.
