Indications for Use
The Mosaic™ Non-modular Proximal Body and EAS Offset Modular Humeral Heads are for use in primary and revision shoulder joint replacement procedures in cases of: Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis Rheumatoid arthritis Revision where other devices or treatments have failed Correction of functional deformity Treatment of acute or chronic fractures with humeral epicondyle (elbow) involvement or humeral head (shoulder), which are unmanageable using other treatment methods Oncology applications
Device Story
Mosaic™ Non-modular Proximal Body and EAS Offset Modular Humeral Heads are orthopedic implants for shoulder joint replacement. Components are used in primary or revision procedures to replace damaged humeral structures. Device is implanted by orthopedic surgeons in a clinical/surgical setting. Implants provide structural replacement for bone, facilitating joint function and pain relief in patients with degenerative disease, fractures, or oncology-related bone loss. Device is used with or without glenoid components.
Clinical Evidence
No clinical data. Substantial equivalence established via non-clinical testing.
Technological Characteristics
Materials: Co-Cr-Mo alloy per ASTM F 75. Design: Non-modular proximal body and EAS offset modular humeral head. Intended for cemented use. Class II device (21 CFR 888.3650).
Indications for Use
Indicated for primary and revision shoulder joint replacement in patients with non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, acute/chronic fractures (humeral head/epicondyle), or oncology applications, including cases where prior treatments failed.
Regulatory Classification
Identification
A shoulder joint metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral 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).
