## Indications for use
Anatomical Shoulder System and ASHCOM Shoulder System Hemi or Total Arthroplasty Application of the Anatomical Shoulder Humeral Stems and Domelock System The Anatomical Shoulder Humeral Stems and Domelock System are indicated for • Advanced wear and tear of the shoulder joint resulting from degenerative, posttraumatic or rheumatoid arthritis. • Avascular necrosis. • Conditions consequent to earlier operations. • Omarthrosis. • Rheumatoid arthritis. • Revision of shoulder prosthesis. The Humeral Stems Cemented are intended for cemented use and the Humeral Stems Uncemented are intended for uncemented use. When used in a total shoulder application, the Anatomical Shoulder Pegged and Keeled Glenoids Cemented and the Biomet all-polyethylene Keeled Glenoid are intended for cemented use only. The Biomet Modular Hybrid Glenoid is intended to be implanted with bone cement. The optional porous titanium peg may be inserted without bone cement. The optional polyethylene peg should be inserted with bone cement. Reverse Application of the Anatomical Shoulder System and ASHCOM Shoulder System • The Anatomical Shoulder Inverse/Reverse System and ASHCOM Shoulder System are indicated for primary, fracture or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency. • The patient’s joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. The Humeral Stems Cemented are intended for cemented use and the Humeral Stems Uncemented are intended for uncemented use. When used with the Anatomical Shoulder Glenoid Fixation, it is intended for uncemented use and requires two screws for fixation. Fracture Application of the Anatomical Shoulder Fracture System The Anatomical Shoulder Fracture System is intended for use in prosthetic replacement of the proximal humerus and the glenoid articular surface of the scapula during total-, hemi and fracture shoulder arthroplasty in treatment of the following: • Complex 3- and 4-part fractures of the proximal humerus with subluxation of the head fragment • Complex 3- and 4-part fractures of the proximal humerus with loosening of the spongiosa in the head fragment • Complex 3- and 4-part fractures of the proximal humerus with additional cross split of the head fragment • Fracture instability after osteosynthesis of 3- and 4-part fracture fragments of the proximal humerus • Posttraumatic necrosis of the humeral head • Posttraumatic arthrosis after humeral head fracture The Humeral Fracture Stems are intended for either cemented or uncemented use. When used in a total shoulder application, the Anatomical Shoulder Pegged and Keeled Glenoids Cemented are intended for cemented use only. Anatomical Shoulder Combined System Advanced destruction of the shoulder joint resulting from: • Omarthrosis. • Rheumatoid arthritis • Post-traumatic arthritis • Avascular necrosis of the humeral head • Cuff-tear arthropathy (Bigliani/Flatow Heads with heights of 27mm or greater) • Conditions following earlier operations (including revision shoulder arthroplasty). The Anatomical Shoulder Combined System is intended for cemented or cementless use. When used with the following humeral stems the Anatomical Shoulder Combined System is intended for cemented use: • Anatomical Shoulder Standard Cemented Humeral Stem. • Anatomical Shoulder Revision Stem. When used with the following humeral stem the Anatomical Shoulder Combined System is intended for cementless use: • Anatomical Shoulder Standard Uncemented Stem. When used with the following humeral stems the Anatomical Shoulder Combined System is intended for cemented or cementless use: • Anatomical Shoulder Fracture Stem. • Anatomical Shoulder Fracture Long Stem. When used with the following glenoids the Anatomical Shoulder Combined System is intended for cemented use: • Bigliani/Flatow Glenoid (pegged and keeled). • Trabecular Metal™ Glenoid.
