Intended Use

The Javelin Shoulder is intended for use in total and hemi-arthroplasty of the shoulder. It is meant to replace the natural humeral head and/or glenoid to relieve pain and reconstruct the joint to re-establish as much normal joint function as possible. The humeral component is for cemented and uncemented use. The glenoid component is for cemented use only.

The indications for use of the Javelin Shoulder when used as a total or hemi-shoulder include:

  • Aseptic necrosis of the humeral head.
  • Painful, disabling joint disease of the shoulder resulting from: degenerative arthritis, rheumatoid arthritis or post-traumatic arthritis.
  • Proximal humeral fracture and/or dislocation.
  • Clinical management problems where arthrodesis or alternative reconstruction techniques are less likely to achieve satisfactory results.

Additional indications for use as a total shoulder include:

  • Revision of previous unsuccessful total shoulder replacement, resurfacing or other procedure.
Device Description

The Javelin Shoulder is a fully anatomic design with an articulating humcral head that will allow it to be placed in the same position as the resected native humeral head. It will allow for variable adjustments for neck angle as well as varus/valgus variances in the neck resection. The humeral heads will be available in multiple diameters and head heights in order to better replicate the normal anatomic range of sizes in patient anatomy. The total system will consist of an array of sizes of humeral components, humeral heads, The total system will over manufactured from the exact same materials as the predicate devices.

AI/ML Overview

This 510(k) summary describes the Javelin Shoulder, an artificial shoulder humeral component. The submission focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria in a clinical study with a detailed statistical analysis of device performance.

Therefore, many of the requested elements for describing acceptance criteria and a study proving their fulfillment are not present in this document. The document describes the device, its intended use, and states that testing was performed to determine the components met performance criteria, but it does not elaborate on these criteria or the study details.

Here's a breakdown of the available and missing information based on your request:

1. Table of acceptance criteria and the reported device performance

Acceptance CriteriaReported Device Performance
Not specifiedTesting was performed to determine the subject components met the performance criteria. (Details of criteria and specific performance outcomes are not provided).

2. Sample size used for the test set and the data provenance

  • Sample size for the test set: Not specified. The document refers to "testing" but does not provide details on the number of components or the nature of the tests (e.g., mechanical, simulated use).
  • Data provenance: Not applicable in the context of human data. The "testing" mentioned would likely involve mechanical and materials testing of the device components, not clinical data from patients.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

  • Not applicable. This is a medical device submission for an orthopedic implant, not an AI/diagnostic device that requires expert-established ground truth from medical images or clinical evaluations. The "truth" here would pertain to the mechanical and material specifications of the implant.

4. Adjudication method for the test set

  • Not applicable. (See answer to #3.)

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

  • No. This is a physical medical device (shoulder implant), not a diagnostic device or AI software that would involve human readers or AI assistance in interpretation.

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

  • No. (See answer to #5.)

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

  • Not explicitly stated for the "testing" mentioned. For a physical implant, ground truth would typically refer to established engineering specifications, material properties, and biomechanical performance standards that the device needs to meet.

8. The sample size for the training set

  • Not applicable. This is not an AI/machine learning device. The "training set" concept does not apply.

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

  • Not applicable. (See answer to #8.)

Summary of what the document does provide regarding device performance:

The document states: "Testing was performed to determine the subject components met the performance criteria." It also emphasizes that the "intended use, material, manufacturing methods, packaging, and sterilization of the predicate and subject components are identical." This suggests that the performance criteria are primarily related to the mechanical and material characteristics of the implant, demonstrating that the Javelin Shoulder performs equivalently to its predicate devices, which are already legally marketed. For implants, performance criteria would typically include:

  • Mechanical strength and fatigue: Ensuring the implant can withstand physiological loads over time without failure.
  • Material biocompatibility: Confirming the materials are safe for implantation in the human body.
  • Dimensional accuracy: Verifying that the components conform to design specifications.
  • Sterility assurance: Confirming effective sterilization methods.

However, the specific tests conducted, the acceptance values for these tests, and the actual results are not detailed in this 510(k) summary. The purpose of a 510(k) summary is to summarize the safety and effectiveness information, not to provide full study reports.

§ 888.3690 Shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis.

(a)
Identification. A shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis is a device made of alloys, such as cobalt-chromium-molybdenum. It has an intramedullary stem and is intended to be implanted to replace the articular surface of the proximal end of the humerus and to be fixed without bone cement (§ 888.3027). This device is not intended for biological fixation.(b)
Classification. Class II.
