Equinoxe ® Primary System

The Equinoxe Shoulder System redefines “anatomical.” The anatomic (primary) shoulder allows the surgeon to replicate a patient’s unique anatomy by independently adjusting parameters in situ.

Patented Replicator Plate

With its patented replicator plate, the Equinoxe system is the only system that provides in situ adjustment of retroversion, neck angle, medial and posterior offset of the humeral head – without the need for trials or back table assembly.1-3

Dual eccentricities (head and replicator plate) provide independent adjustability of both medial and posterior offset to empower the surgeon to anatomically orient the humeral head.2-4

Glenoid Solutions

The Equinoxe system offers a wide range of glenoid solutions, including pear shaped, pegged, keeled and augmented options. The cage glenoid pegs are designed to simplify removal and reduce operating room time.5

The Equinoxe 8 and 16 degree posterior augment glenoids are designed to preserve bone1 and address initial and biologic fixation in both straightforward and challenging cases.

Humeral Head

The anatomic stem enables surgeons to convert from a total shoulder to a reverse without stem removal5.

Multiple head heights for each diameter provides surgeon flexibility in patients with soft tissue challenges, and the alpha and beta glenoid curvatures enable any head size to be paired with any glenoid size while maintaining an optimal radial mismatch of approximately 5.5mm.6-8  Exactech offers the CTA Head for cuff tear arthropathy procedures.
