Monolithic percutaneous-screw system for spinal surgeries

A monolithic percutaneous-screw system for use in spinal surgery, the system comprising:

• a receiver having a distal base and a pair of opposing arms extending proximally from the base;
• a pair of opposing distal breakoff sections, each connected monolithically to a proximal end of a corresponding one of the pair of opposing arms;
• a pair of opposing proximal breakoff sections;
• a pair of opposing intermediate extenders each comprising an outer wall and an inner wall, the outer walls each extending from a distal end, connected monolithically to a corresponding one of the pair of opposing distal breakoff sections, to a proximal end connected monolithically to a corresponding one of the pair of opposing proximal breakoff sections;
• and
• a guide cap connected monolithically to both of the pair of opposing proximal breakoff sections, the guide cap defining a proximal opening having a circular cross-sectional configuration and a passageway in communication with the opening, the inner walls converging proximal to the opposing proximal breakoff sections to define a body that is positioned within the passageway;
• wherein:
• the pair of opposing proximal breakoff sections are each recessed inwardly from an outer surface of one of the pair of intermediate extenders and an outer surface of the guide cap;
• an outer lateral surface of each of the pair of opposing distal breakoff sections is setback from an adjacent outer surface of a corresponding one of the pair of opposing arms connected to the pair of opposing distal breakoff sections;
• each of two end surfaces of each of the pair of opposing distal breakoff sections is setback from an adjacent side surface of a corresponding one of the pair of opposing arms connected to the pair of opposing distal breakoff sections;
• an outer lateral surface of each of the pair of opposing proximal breakoff sections is setback from an adjacent outer surface of a corresponding one of the pair of opposing intermediate extenders connected to the pair of opposing proximal breakoff sections;
• and
• each of two end surfaces of each of the pair of opposing proximal breakoff sections is setback from an adjacent side surface of a corresponding one of the pair of opposing intermediate extenders connected to the pair of opposing proximal breakoff sections.
