The Catalyst R1 Reverse Shoulder System is a reverse total shoulder replacement for patients with a functional deltoid muscle and a grossly deficient rotator cuff joint suffering from pain and dysfunction due to:
· Severe arthropathy with a grossly deficient rotator cuff;
- · Previously failed joint replacement with a grossly deficient rotator cuff;
- Fracture of glenohumeral joint from trauma or pathologic conditions of the shoulder including humeral head fracture, displaced 3- or 4-part fractures of proximal humerus, or reconstruction after tumor resection:
- · Bone defect in proximal humerus;
- · Non-inflammatory degenerative disease including osteoarthritis and avascular necrosis of the natural head and/ or glenoid:
- · Inflammatory arthritis including rheumatoid arthritis;
- · Correction of functional deformity
The humeral stems are intended for cemented or uncemented applications.
The glenoid baseplate is intended for uncemented use with the addition of screws for fixation.
The Catalyst R1 Reverse Shoulder System is a total shoulder prosthesis designed for use in patients with a non-functional rotator cuff. The articulation of this reverse design is inverted compared to a traditional anatomic total shoulder prosthesis, where the articulating sphere is on the glenoid side of the joint, and the mating insert is fixed into the humeral stem implant.
This submission is to add semi-constrained polyethylene inserts to the R1 Reverse Shoulder System. The semi-constrained polyethylene inserts are a design modification of the polyethylene inserts cleared in K202611. The semi-constrained polyethylene inserts are not replacing the standard polyethylene inserts cleared in K202611 but are an additional option and are compatible with all components within the R1 Reverse Shoulder System.
Unfortunately, the provided document does not contain the information required to answer your request. The document describes a 510(k) premarket notification for a medical device (Catalyst R1 Reverse Shoulder System) and specifically states:
"Clinical testing was not necessary to demonstrate substantial equivalence of the R1 Reverse Shoulder System with semi-constrained polyethylene inserts to the predicate device."
This means that the device's clearance was based on demonstrating substantial equivalence to an already marketed predicate device, rather than on new clinical studies or elaborate performance validations with acceptance criteria and ground truth establishment as would be typical for AI/ML-based medical devices or devices demonstrating novel performance.
Therefore, I cannot provide details on:
- Acceptance criteria and reported device performance: No specific performance metrics for this device, beyond range of motion analysis (which is stated as "adequate for its intended use" without specific numerical criteria), are presented in the form of a table.
- Sample size, data provenance, ground truth experts, adjudication, MRMC studies, standalone performance, training set details: These elements are characteristic of studies evaluating the performance of diagnostic algorithms or devices where a "ground truth" needs to be established and compared against device output. Since clinical testing was deemed unnecessary for this particular 510(k) clearance, such studies are not described in the document.
The document focuses on:
- The device description and intended use.
- Comparison to predicate devices, highlighting similarities in design, materials, and indications.
- Non-clinical testing (range of motion analysis).
§ 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)
