The indications for the Corin Icona Hip Stem as a total hip arthroplasty, and when used in combination with a Corin hemiarthroplasty head, as a hip hemiarthroplasty, include:

• · Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis
• Rheumatoid arthritis
• · Correction of functional deformity
• · Treatment of non-union and femoral neck fractures
• Developmental dysplasia of the hip (DDH) / congenital dysplasia of the hip (CDH)

The Corin Icona Hip Stem is indicated for cementless use only.

The Corin Icona Hip Stem is a tapered stem design manufactured from Titanium alloy (Ti6Al4V) (ASTM F136) with a layer of commercially pure titanium (ISO 5832-2, ASTM F1580) and an additional layer of electrochemically deposited calcium phosphate (ASTM F1609) applied.

The Icona Hip Stem is intended for use in hemiarthroplasty and total hip arthroplasty in skeletally mature patients, to provide increased mobility and reduce pain by replacing the damaged hip joint articulation where there is evidence of sufficient sound bone to seat and support the components.

The design is a fully-coated titanium femoral hip stem featuring a polished neck with 12/14 tapered male trunnion for assembly with Corin modular femoral head components. Additionally, the Icona stem features a trapezoidal, tripled tapered body, providing for rotational and axial stability.

The Icona Hip Stem is a collared stem available in two different offsets (Standard and Lateralised) and twelve (12) different sizes, totaling 24 options.

The Icona Hip Stem is compatible with the following acetabular systems:

· Traditional – Trinity (K093472, K110087, K111481, K122305, K130128, K130343, K131647) and Trinity PLUS (K17255) · Dual mobility - Trinity Dual Mobility (K170359) and MobiliT (K191831)

· Bipolar - Bipolar-i (K183114)

This document is a 510(k) Premarket Notification from the FDA for a hip stem device (Icona Hip Stem). It does not describe an AI/ML medical device, but rather a traditional medical device (hip implant). Therefore, much of the requested information regarding acceptance criteria and studies for AI/ML performance metrics (like sample size for test/training sets, experts for ground truth, MRMC studies, standalone performance, etc.) is not applicable to this document.

However, I can extract the relevant information regarding the traditional device's performance criteria and supporting studies as presented in the document:

1. Table of Acceptance Criteria and Reported Device Performance

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

This information is typically not provided in detail within a 510(k) summary for mechanical testing of traditional orthopedic implants. The document states "Non-clinical testing and rationales provided to support substantial equivalence," but does not specify sample sizes for these mechanical tests (e.g., number of stems tested for fatigue).

• Provenance: The tests are non-clinical (laboratory/mechanical testing), not patient data.

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

Not applicable for a traditional orthopedic implant's mechanical testing or equivalence comparison to predicate devices. "Ground truth" in this context would refer to established engineering standards (ISO, ASTM) and the performance of predicate devices.

4. Adjudication Method

Not applicable for this type of device submission. Adjudication is relevant for expert review of data, often in clinical studies or for AI ground truth establishment.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done

No, this is not an AI/ML device, so an MRMC study comparing human readers with and without AI assistance is not applicable.

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

No, this is not an AI/ML device.

7. The Type of Ground Truth Used

For this traditional device, the "ground truth" used to establish substantial equivalence is primarily:

• Established engineering standards: ISO 7206-4, ISO 7206-6, ISO 21535, ASTM F136, ASTM F1580, ASTM F1609. The device's performance in these tests is compared against the performance of the predicate devices or the requirements of these standards.
• Performance of legally marketed predicate devices: The Icona Hip Stem's design, materials, and mechanical performance are compared to those of already cleared predicate devices. Substantial equivalence implies that the new device performs as safely and effectively as the predicate.

8. The Sample Size for the Training Set

Not applicable, as this is not an AI/ML device; there is no "training set."

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

Not applicable, as there is no "training set."
