The MultilockHumerusNail System is intended for the fixation of fractures and reconstruction of the humerus. It is indicated for use in treating proximal, diaphyseal, and distal humeral fractures, including comminuted, segmental, and pathological fractures, as well as nonunions and malunions. The system provides intramedullary stabilization with multiple locking options to ensure secure fixation and facilitate early mobilization.
