Equinoxe Primary System

In situ adjustability. Infinite possibilities.

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.


Our alpha/beta curvatures allows use of any size head with any size glenoid. The 8° and 16° augmented glenoids offer bone preserving1 solutions for challenging glenoids. The new cage glenoid allows for initial fixation through a press-fit bone cage; its pegs are designed with features to simplify removal. 

Replicator Plate

The replicator plate provides in situ adjustment (± 7.5˚) for both version and neck angle 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

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.
