## Intended Use

The Osteonics® All Polyethylene Shoulder Glenoid Components are single-use devices. They are intended for cemented fixation within the prepared glenoid fossa of the shoulder. The Osteonics® All Polyethylene Glenoid Shoulder Components, in conjunction with their mating humeral components, are intended for total shoulder arthroplasty.

## Device Story

The Osteonics All Polyethylene Glenoid Shoulder Component is a prosthetic implant for total shoulder arthroplasty. It is designed for cemented fixation into the surgically prepared glenoid fossa. The device features a spherical bearing surface with a larger radius than the mating humeral head to allow for translation, and a keeled fixation post for stability. It includes an embedded cobalt-chromium x-ray marking wire for radiographic visualization. The device is implanted by an orthopedic surgeon in a clinical/hospital setting. By replacing the damaged glenoid surface, the device aims to reduce pain and restore joint function in patients with severe shoulder pathology.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Material: ASTM F-648 UHMWPE body; ASTM F-90 cobalt-chromium alloy x-ray marking wire. Design: Keeled fixation post; spherical bearing surface geometry for translation. Fixation: Cemented. Sterilization: Not specified.

## Regulatory 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).

510(k) Premarket Notification

## Device Description

The keeled Osteonics® All Polyethylene Glenoid Shoulder Component is intended for cemented fixation within the surgically prepared glenoid fossa of the shoulder.

The Osteonics® All Polyethylene Glenoid Shoulder Component is shaped to conform to the geometry of the glenoid fossa. Its medial surface is curved so that, when placed against the prepared glenoid cavity, the device conforms to the shape of the cavity. This conformity allows less bone removal and may provide the component with added stability.

The spherical radius of the bearing surface Osteonics® All Polyethylene Glenoid Shoulder Component is larger than the spherical radius of the mating humeral head. This is intended to allow translation.

The Osteonics® All Polyethylene Glenoid Shoulder Component comes in a range of sizes. Each component features a pre-assembled, x-ray marking wire on its medial surface. Each component features a keeled fixation post.

The body of the Osteonics® All Polyethylene Glenoid Shoulder Component is manufactured from ASTM F-648 ultra-high molecular weight polyethylene (UHMWPE). The x-ray marking wire is manufactured from ASTM F-90 cobalt chromium alloy.

## Intended Use:

The Osteonics® All Polyethylene Shoulder Glenoid Components are single-use devices. They are intended for cemented fixation within the prepared glenoid fossa of the shoulder.

The Osteonics® All Polyethylene Glenoid Shoulder Components, in conjunction with their mating humeral components, are intended for total shoulder arthroplasty. The indications for use are as follows:

## Indications:

- Aseptic necrosis of the humeral head.
- Painful, disabling joint disease of the shoulder resulting from: degenerative arthritis, rheumatoid arthritis or post-traumatic arthritis.
- Proximal humeral fracture and/or dislocation.
- Revision of previous unsuccessful total shoulder replacement, resurfacing or other procedure.
- Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.
