Intended Use

Biomet's Bipolar Shoulder Prosthesis is indicated for use in most cases where a conventional shoulder hemi-arthroplasty would be indicated. Typical indications include osteoarthritis, avascular necrosis, traumatic arthritis, rheumatoid arthritis, correction of severe functional deformity, revision procedures where other treatments or devices have failed, fracture, and cuff tear arthropathy. This device is a single use implant intended for cemented application only. It is intended for use with Biomet's humeral components previously cleared by the FDA for cemented application.

Device Story

Bipolar Shoulder Prosthesis is a self-retaining humeral implant; designed to articulate with natural glenoid surface, eliminating need for separate glenoid component. Device consists of outer metallic shell (40mm-52mm diameters) with inserted polyethylene liner and retaining ring; modular heads correspond to humeral stem geometry. Used in orthopedic surgery; implanted by physician. Bi-rotational nature allows for increased range of motion compared to standard hemi-arthroplasty. Intended for cemented application with previously cleared Biomet humeral stems. Benefits include joint restoration and correction of functional deformity in patients with degenerative or traumatic shoulder conditions.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design and functional comparison to legally marketed predicate devices.

Technological Characteristics

Metallic humeral prosthesis; modular design with outer shell, polyethylene liner, and retaining ring. Available in four outer diameters (40mm-52mm). Designed for cemented fixation to humeral stems. Bi-rotational articulation mechanism.

Indications for Use

Indicated for patients requiring shoulder hemi-arthroplasty due to osteoarthritis, avascular necrosis, traumatic arthritis, rheumatoid arthritis, severe functional deformity, failed prior treatments, fracture, or cuff tear arthropathy. Intended for single-use, cemented application.

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).
