Device Story

Discovery™ Elbow - Mosaic™ Distal Humeral Replacement System is a cemented elbow prosthesis for distal humeral bone loss. System components include ulnar stem with pre-assembled bearing, distal humeral component, humeral condyle kit, extramedullary modular distal segment, intramedullary humeral stem, soft tissue attachment sleeves, and canal cement plugs. Device functions as a hinge to replace the distal humerus. Used by orthopedic surgeons in clinical settings to restore joint function, correct deformity, or manage fractures/oncology cases. Output is a mechanical joint replacement; clinical decision-making relies on surgeon assessment of bone loss and joint pathology. Benefits include restoration of elbow function and stability in complex orthopedic cases.

Clinical Evidence

No clinical data provided.

Technological Characteristics

Metal/polymer constrained cemented elbow prosthesis. Components include ulnar stem, distal humeral component, humeral condyle kit, modular distal segment, intramedullary humeral stem, and soft tissue sleeves. Designed for use with bone cement.

Indications for Use

Indicated for patients with non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, acute/chronic fractures with humeral epicondyle involvement, or oncology applications requiring distal humeral replacement, including revision cases.

Regulatory Classification

Identification

An elbow joint metal/polymer constrained cemented prosthesis is a device intended to be implanted to replace an elbow joint. It is made of alloys, such as cobalt-chromium-molybdenum, or of these alloys and of an ultra-high molecular weight polyethylene bushing. The device prevents dislocation in more than one anatomic plane and consists of two components that are linked together. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).
