1. Robust scope of eccentric heads provides intra-operative flexibility
2. Patented anterior-lateral fin – aligning fin with distal portion of bicipital groove establishes version^{1, 2, 3}
   
3. A/P handles and cerclage hole – a) stable base holds tuberosities; b) easy to thread for cerclage suture technique
4. Multiple fin holes with rounded edges provide suturing versatility
5. Asymmetric tuberosity beds address primary failure mode of complex fractures following hemiarthroplasty – tuberosity nonunion^{1, 2, 3}
   
6. Grit blast encourages bone ongrowth
7. Fully integrated with Equinoxe reverse implant options
8. Grafting window promotes tuberosity apposition
9. Satin finish and distal grooves facilitate cement fixation
