The Equinoxe Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases or fractures of the glenohumeral joint where total or hemi- arthroplasty is determined by the surgeon to be the preferred method of treatment.
Clinical indications for the PRIMARY (P), LONG/REVISION (L), and FRACTURE (F) humeral components are as follows:
| P | L | F | Indications |
|---|---|---|---|
| √ | √ | Rheumatoid arthritis, osteoarthritis, osteonecrosis or post-traumatic degenerative problems | |
| √ | √ | Congenital abnormalities in the skeletally mature | |
| √ | Primary and secondary necrosis of the humeral head. | ||
| √ | √ | Humeral head fracture with displacement of the tuberosities | |
| √ | √ | Pathologies where arthodesis or resectional arthroplasty of the humeral head are not acceptable | |
| √ | √ | Revisions of humeral prostheses when other treatments or devices have failed (where adequate fixation can be achieved) | |
| √ | Displaced three-part and four-part upper humeral fractures | ||
| √ | Spiral and other fractures of the mid-humerus (in combination with glenohumeral degenerative diseases) | ||
| √ | Revision of failed previous reconstructions when distal anchorage is required | ||
| √ | √ | To restore mobility from previous procedures (e.g. previous fusion) |
The Equinoxe Reverse Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint and a grossly deficient, i rreparable rotator cuff. The Equinoxe Reverse Shoulder is also indicated for a failed glenohumeral joint replacement with loss of rotator cuff function resulting in superior migration of the humeral head.
The Equinoxe Platform Fracture Stem is indicated for use in skeletally mature individuals with acute fracture of the proximal humerus and displacement of the tuberosities, displaced 3- and 4part fractures of the proximal humerus (hemi-arthroplasty), or acute fracture of the proximal humerus with failure of the glenohumeral joint (primary total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is also indicated for acute fracture of the proximal humerus in combination with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty). The Equinoxe Platform Fractures Stein is indicated for cemented use only.
The Exactech Equinoxe Platform Fracture Stem is a cemented humeral stem designed for use with the Equinoxe primary shoulder components and the Equinoxe reverse shoulder components. The Equinoxe Platform Fracture Stem is intended to be used in cemented applications for repair of acute fracture of the proximal humerus.
The proposed and predicate (K092900) fracture stems have identical design features. However, the proposed stems will be made from forged titanium alloy (per ASTM F136 and ASTM F620), as opposed to the wrought titanium alloy (ASTM F1472) used in the predicate stems.
The provided document is a 510(k) premarket notification for a medical device, the Exactech® Equinoxe® Platform Fracture Stem. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study with acceptance criteria for device performance in a clinical or AI context.
Therefore, much of the requested information regarding acceptance criteria, performance metrics, sample sizes for test/training sets, expert qualifications, ground truth establishment, adjudication methods, and MRMC/standalone studies, cannot be found in this document.
The document describes material and mechanical testing to support substantial equivalence, not a study evaluating clinical performance or AI algorithm performance.
Here's what can be extracted from the provided text:
1. A table of acceptance criteria and the reported device performance
The document describes engineering evaluations for substantial equivalence, not a clinical performance study with acceptance criteria for performance metrics like sensitivity, specificity, accuracy, or reader improvement with AI.
| Acceptance Criteria (from this document) | Reported Device Performance (from this document) |
|---|---|
| Constructs must meet criteria without failure in dynamic compression test. | All constructs met the criteria without failure. |
| Device must be sufficient to sustain clinically relevant loads during its expected life under worst-case conditions. | An engineering evaluation determined that the proposed device is sufficient to sustain clinically relevant loads during its expected life. |
2. Sample size 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 "tests" described are engineering and mechanical evaluations of the device itself (compression test, engineering evaluation), not a study involving patient data.
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 provided in the document. The "ground truth" for the engineering tests would be the physical properties and performance characteristics of the materials and device design, established by engineering principles and testing standards, not by medical experts.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not provided in the document. Adjudication methods are relevant for clinical assessments or expert consensus, not for the mechanical testing described 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
There was no MRMC comparative effectiveness study and therefore no effect size reported. This document is for a physical implantable device, not an AI-powered diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
There was no standalone algorithm performance study. This document is for a physical implantable device, not an AI-powered diagnostic tool.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the mechanical tests, the ground truth would be based on engineering and material science principles and standards (e.g., ability to withstand specified loads, material properties conforming to ASTM standards). There is no mention of expert consensus, pathology, or outcomes data as ground truth for the evaluations presented.
8. The sample size for the training set
This information is not applicable and is not provided. There is no "training set" as this is not an AI/machine learning study.
9. How the ground truth for the training set was established
This information is not applicable and is not provided. There is no "training set" as this is not an AI/machine learning study.
