Traumatic or pathologic conditions of the shoulder resulting in fracture of the glenohumeral joint. Including humeral head fracture and displaced 3-or 4-part proximal humeral fractures.
The usual goal of total shoulder replacement is to relieve or eliminate pain. The Aequalis Shoulder Fracture System is intended to accomplish these goals. With the Aequalis Shoulder Fracture System, the natural glenoid is replaced as warranted by the state of disease or injury. Thus the Aequalis Shoulder Fracture System is intended for use as a total shoulder replacement system, or as a hemi-shoulder. The modular nature of the system allows for the later conversion of a primary hemiarthroplasty to a total shoulder replacement. The present Device Modification submission consists in the addition of a long stem to each diameter of the previous range.
This document is a 510(k) premarket notification for a medical device (AEQUALIS Shoulder Fracture System), not a study report. Therefore, it does not contain the information required to describe acceptance criteria and a study proving the device meets those criteria.
The document states that the FDA reviewed the premarket notification and determined the device is "substantially equivalent" to legally marketed predicate devices. This means that the device meets the regulatory requirements for marketing, but it does not involve a specific clinical study with acceptance criteria and a detailed performance evaluation as would be found in a clinical trial report.
Here's why the requested information cannot be extracted from the provided text:
- Acceptance criteria and reported device performance: This document does not detail specific acceptance criteria for performance metrics (e.g., success rates, complication rates, range of motion improvements) or report any performance data from a study.
- Sample size, data provenance: No study is described, so no sample size or data origin is mentioned.
- Number of experts, qualifications, adjudication method: These pertain to establishing ground truth in a clinical or imaging study, which is not present here.
- MRMC comparative effectiveness study: No such study is mentioned or implied.
- Standalone (algorithm only) performance: This is a physical implant, not an algorithm.
- Type of ground truth: Ground truth is not relevant in this context, as no performance data based on ground truth is being presented.
- Training set sample size/ground truth: This pertains to machine learning models, which is not what this document is about.
In summary, the provided text is a regulatory filing for marketing clearance, not a scientific or clinical study report.
§ 888.3660 Shoulder joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
