    MODIFICATION TO AVALON CUP SYSTEM

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    Indication: for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following:

    1. Non-inflammatory degenerative joint disease including: osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia,
    2. Inflammatory degenerative joint disease including rheumatoid arthritis;
    3. Correction of functional deformity;
    4. Revision procedures where other treatments or devices have failed; and, treatment of nonunion, femoral neck fractures of the proximal femur with head Involvement that are unmanageable using other techniques.
    Device Description

    The Avalon cup is manufactured from Titanium 6AL 4V Eli (ASTM F136). The Avalon Cup is porous coated with commercial pure (CP) titanium sintered beads (ASTM F67) to promote fixation. The Avalon Cup is a low profile cup available in three versions: [No-hole], [Three hole], and a [Multi-hole]. The holes are to allow for added fixation with bone screws. The Avalon Cup's outer geometry consists of a 14° flared rim and 8 external cutouts, which are machined into the peripheral exterior of the cup.

    AI/ML Overview

    The provided document, K022711 for the Avalon Cup System, is a 510(k) premarket notification for an orthopedic implant. It primarily focuses on demonstrating substantial equivalence to a previously cleared device. Therefore, it does not contain the detailed information requested regarding specific acceptance criteria, a dedicated study proving performance against those criteria, or an AI/algorithm-related evaluation.

    The document states:

    "The proposed device modification has been tested and meets and exceeds the requirements provided in the Draft Guidance Document for Testing Orthopedic Implants With Modified Metallic Surfaces Apposing Bone Or Bone Cement."

    and

    "The Avalon Acetabular cup system demonstrated adequate performance in design control activities."

    However, it does not provide the acceptance criteria, the specific study results, or any of the detailed information about sample size, ground truth, expert involvement, or AI performance as requested. The "modification" is a "line extension" to add a sintered beaded coated option, which is explicitly stated to have no changes to any other aspect of the cup. The basis of substantial equivalence relies on the new device being "identical (except for sintering process)" to the previously cleared device.

    Therefore, I cannot populate the table or answer the specific questions about acceptance criteria, study details, and AI evaluation based on the information provided in this 510(k) summary. The document is about demonstrating equivalence for a minor material change, not about proving device performance against detailed statistical acceptance criteria or evaluating an algorithm.

    AI/ML Overview

    The provided text is a 510(k) Premarket Notification from the FDA for the "Avalon Cup System." This document is a regulatory approval, not a scientific study describing device performance and acceptance criteria.

    Therefore, I cannot provide the requested information about acceptance criteria and a study proving device performance because the document does not contain this type of data.

    Specifically:

    • It does not contain a table of acceptance criteria or reported device performance.
    • It does not describe any study, sample sizes, data provenance, expert qualifications, or adjudication methods.
    • It does not mention MRMC comparative effectiveness studies, standalone algorithm performance, or ground truth types.
    • It does not discuss training sets or how ground truth for training sets was established.

    This document solely indicates that the FDA has reviewed the submission for the Avalon Cup System and determined it is "substantially equivalent" to legally marketed predicate devices, allowing it to be marketed. It lists the indications for use but does not delve into the specific performance data that led to this determination.
