Intended Use

The AETOS Shoulder System (when used with the AETOS Humeral Meta Stems) is to be used only in patients with an intact or reconstructable rotator cuff, where it is intended to provide increased mobility and stability and to relieve pain. The AETOS humeral stems (AETOS Humeral Meta Stems) and head may be used by themselves, as a hemiarthroplasty, if the natural glenoid provides a sufficient bearing surface, or in conjunction with the glenoid, as a total replacement. When used with the AETOS Humeral Meta Stems, The AETOS Shoulder System is indicated for use as a replacement of shoulder joints disabled by: Rheumatoid arthritis Non-inflammatory degenerative joint disease Correction of functional deformity Fractures of the humeral head Traumatic arthritis Revision of other devices if sufficient bone stock remains The AETOS Shoulder System (when used with AETOS Stemless Humeral Prosthesis) is to be used only in patients with an intact or reconstructable rotator cuff. When used with AETOS Stemless Humeral Prosthesis, the AETOS Shoulder System is indicated for anatomic total shoulder replacement of shoulder joints disabled by: Non-inflammatory degenerative joint disease Traumatic arthritis Revision of other devices if sufficient bone stock remains The coated humeral components are intended for uncemented use. The glenoid component is intended for cemented use only. In Reverse: The AETOS Shoulder System, when used with AETOS Humeral Meta Stems, is indicated for use as a replacement of shoulder joints for patients with a functional deltoid muscle and with massive and non-repairable rotator cuff-tear with pain disabled by: Rheumatoid arthritis Non-inflammatory degenerative joint disease Correction of functional deformity Fractures of the humeral head Traumatic arthritis Revision of devices if sufficient bone stock remains The humeral liner component is indicated for use in the AETOS Shoulder System as a primary reverse total shoulder replacement and for use when converting an anatomic AETOS Shoulder System into a reverse shoulder construct. This facilitates the conversion without the removal of the humeral stem during revision surgery for patients with a functional deltoid muscle. The component is permitted to be used in the conversion from anatomic to reverse if the humeral stem is well fixed, the patient has a functional deltoid muscle; the arthroplasty is associated with a massive and nonrepairable rotator cuff tear. The coated humeral stems are indicated for uncemented use. The coated glenoid base plate is intended for cementless application with the addition of screws for fixation. Note: All implant components are single use.

Device Story

Device replaces diseased shoulder joint surfaces; restores mobility/stability; relieves pain. Used in clinical settings by orthopedic surgeons. Implanted via surgical procedure; provides mechanical bearing surface for glenohumeral joint. Benefits include joint function restoration and pain relief for patients with degenerative conditions. Single-use implant.

Clinical Evidence

No clinical data; bench testing only. Performance data includes construct fatigue and corrosion resistance, post-fatigue stability, static disengagement, dynamic stability/loosening, and bone volume/contact analysis.

Technological Characteristics

Stemless humeral prosthesis; press-fit fixation; metallic/polymer construction; single-use; uncemented humeral components; cemented glenoid components; cementless glenoid base plate with screw fixation.

Indications for Use

Indicated for skeletally mature patients with degenerative glenohumeral joint disease requiring anatomic total shoulder replacement (intact/reconstructable rotator cuff) or reverse total shoulder replacement (massive/non-repairable rotator cuff tear, functional deltoid). Conditions include rheumatoid arthritis, non-inflammatory degenerative joint disease, functional deformity, humeral head fractures, traumatic arthritis, and revision of prior devices with sufficient bone stock.

Regulatory Classification

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).
