The provided document is a 510(k) premarket notification for a medical device called "Trident® II Tritanium® Acetabular Shells and 6.5 mm Low Profile Hex Screws." This document focuses on demonstrating substantial equivalence to previously cleared predicate devices, rather than detailing a study that proves the device meets specific acceptance criteria in the context of an AI/ML-driven medical device.
Therefore, most of the requested information (acceptance criteria table, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, training set details) is not present in this document as it pertains to AI/ML device validation, which is not the subject of this 510(k) submission.
However, I can extract the following relevant information based on the typical requirements for a 510(k) submission for a non-AI/ML device:
-
Acceptance Criteria and Reported Device Performance:
The document states that "performance testing show that the Trident® II Tritanium® Acetabular Shell and 6.5mm Low Profile Hex Screw are substantially equivalent to the predicates in terms of intended use, indications, design, materials, performance characteristics and operational principles." This implies that the acceptance criteria are met if the device's performance is comparable to the predicate devices. The performance is assessed through various non-clinical laboratory tests.Acceptance Criteria (Implied: Substantially Equivalent to Predicate) Reported Device Performance (Summary) Mechanical strength and fixation (e.g., push-out, lever-out, torque-out, fatigue, plastic deformation) Device demonstrated acceptable performance in all listed non-clinical tests (e.g., Push out (ASTM F1820), Lever out (ASTM F1820), Torque out (ASTM F1820), Fatigue, Plastic Deformation) ensuring substantial equivalence to predicate. Bone screw performance Demonstrated acceptable performance based on Bone Screw Testing (ASTM F543). Porous surface characteristics Porous surface meets requirements outlined in FDA guidance documents ("Guidance Document for Testing Orthopedic Implants With Modified Metallic Surfaces Apposing Bone Or Bone Cement"). Biocompatibility / Pyrogenicity Achieved acceptable endotoxin limit as specified in ANSI/AAMI ST72:2011 via Bacterial endotoxin testing (BET). Range of Motion Acceptable Range of Motion Analysis was performed. Fretting Evaluation (for MDM liner) Acceptable Fretting Evaluation of the MDM liner was performed. Material Chemistry Acceptable Material Chemistry evaluations were performed. -
Sample size used for the test set and the data provenance: Not applicable to this type of device submission. The tests are laboratory-based, often using a small number of physical samples (e.g., implants, screws) for mechanical testing to destruction or specific load cycles.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for mechanical performance is typically established through adherence to standardized test methods (e.g., ASTM standards) and material science principles, interpreted by engineers and material scientists.
-
Adjudication method for the test set: Not applicable. Performance data from laboratory tests do not involve human adjudication in the way clinical or image-based studies do.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done: No, an MRMC study was not done as this is a physical medical implant, not an AI/ML diagnostic or assistive device.
-
If a standalone performance study was done: The non-clinical laboratory testing represents the standalone performance evaluation of the device's physical and mechanical properties.
-
The type of ground truth used: The "ground truth" for this device's performance is defined by established engineering and materials science principles, standard test methodologies (e.g., ASTM standards), and regulatory guidance documents for orthopedic implants. For example, for mechanical strength tests, the ground truth is often a failure point or a resistance level under specific applied loads. For biocompatibility/pyrogenicity, it's the defined acceptable endotoxin limit.
-
The sample size for the training set: Not applicable. This device is not an AI/ML product developed using a training set.
-
How the ground truth for the training set was established: Not applicable.
In summary, this 510(k) document is for a traditional medical device (hip implant) and therefore lacks the detailed information typically requested for AI/ML device validation studies. The "study" mentioned here refers to the battery of non-clinical laboratory tests performed to demonstrate that the device is substantially equivalent to legally marketed predicate devices.
