Standardized Humeral Preparation

• The Equinoxe’s platform system enables a surgeon to convert from a total shoulder to a reverse without humeral stem removal.
• Using the same humeral stem, humeral instrumentation and humeral osteotomy for both indications standardizes the procedure and empowers the surgeon to intra-operatively decide ‘primary vs. reverse’.

Standardized Glenoid Preparation

• The offset bone cage of the glenoid baseplate is sized and positioned to be placed in the center of the glenoid to fill a central bone defect while distally shifting the glenosphere to ensure inferior overhang.
• The six screw holes of the glenoid baseplate are positioned to provide screw fixation, even when revising a pegged or keeled glenoid to a reverse shoulder.

Scapular notching is currently addressed in the marketplace with implant designs that either a) lateralize the center of rotation, which causes greater torque on the glenoid, or b) require additional bone-consuming surgical techniques such as inferiorly tilting the baseplate or pre-notching the bone.¹ Both of these options create the potential for long-term glenoid fixation challenges. The Equinoxe Reverse Shoulder, however, minimizes scapular notching exclusively in design while maintaining a medialized center of rotation without unnecessary bone consuming techniques. These critical attributes, along with the seamlessly integrated platform stem, differentiate the Equinoxe and provide a compelling reason for a surgeon to Experience the Power of the Equinoxe.
