This document provides the surgical technique for using a proximal humerus implant system to treat fractures of the proximal humerus. It describes positioning the patient and plate, drilling fixation holes in the humeral head while avoiding the joint, determining screw length and location, and inserting screws into the head and shaft for fixation. Calcar screws are recommended for varus displaced fractures or medial comminution to add stability. The technique aims to preserve bone and nerves while stabilizing the fracture for healing.
