## Indications for use
The Equinoxe Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases or fractures of the glenohumeral joint where total or hemi-arthroplasty is determined by the surgeon to be the preferred method of treatment. • The cemented primary humeral stem, long/revision stem, fracture stems, and all Equinoxe glenoids are intended for cemented fixation. • The press-fit humeral stems are intended for press-fit applications but may be used with bone cement at the discretion the surgeon. • The reverse humeral components are intended to be used in cemented applications or in revision cases when the humeral component is well-fixed/stable, as deemed by the orthopaedic surgeon. • Humeral Heads are intended for use in cemented and press-fit applications. Clinical indications for the PRIMARY (P), LONG/REVISION (L), and FRACTURE (F) humeral components are as follows: P L F Indications √ √ Rheumatoid arthritis, osteoarthritis, osteonecrosis or post-traumatic degenerative problems √ √ Congenital abnormalities in the skeletally mature √ Primary and secondary necrosis of the humeral head. √ √ Humeral head fracture with displacement of the tuberosities √ √ Pathologies where arthrodesis or resectional arthroplasty of the humeral head are not acceptable √ √ Revisions of humeral prostheses when other treatments or devices have failed (where adequate fixation can be achieved) √ Displaced three-part and four-part upper humeral fractures √ Spiral and other fractures of the mid-humerus (in combination with glenohumeral degenerative diseases) √ Revision of failed previous reconstructions when distal anchorage is required √ √ To restore mobility from previous procedures (e.g. previous fusion) The Equinoxe Reverse Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff. The Equinoxe Reverse Shoulder is also indicated for a failed glenohumeral joint replacement with loss of rotator cuff function resulting in superior migration of the humeral head. The Equinoxe Platform Fracture Stem is indicated for use in skeletally mature individuals with acute fracture of the proximal humerus and displacement of the tuberosities, displaced 3- and 4-part fractures of the proximal humerus (hemi-arthroplasty), or acute fracture of the proximal humerus with failure of the glenohumeral joint (primary total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is also indicated for acute fracture of the proximal humerus in combination with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is indicated for cemented use only.
