The Anatomical Shoulder Fracture System treats complex 3- and 4-part fractures of the proximal humerus. With the unique features and anatomical design of this stem, a complex case is now simplified with this specially designed implant for tough fracture cases. The aggressive fracture spikes allow for stable anchoring of the tuberosities to the stem — increasing primary stability. Additionally, the system offers a left and right proximal configuration of the humeral head that optimizes suture hole orientation in order to aid in the repositioning of the tuberosities below the head, restoring the original anatomy.
