Revision connectors, systems, and methods thereof

A modular connector system comprising:

• a connector having a body having an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface, the body having a first clamping portion and a second modular portion;
• the first clamping portion having:
• a first passage having a first longitudinal axis extending therethrough such that the longitudinal axis extends in a direction from the upper surface to the lower surface,
• the first passage being sized to allow a first rod to be inserted therein;
• a bottom portion having an opening in communication with the first passage;
• and
• a first securing mechanism comprising a set screw, a clamp having two opposing legs, and an opening defined between the two opposing legs, the clamp being connected to the set screw and the set screw being rotatably connected to the body, the first securing mechanism having an unlocked position configured to receive the first rod and a locked position configured to releasably secure the first rod in the opening between the two opposing legs of the clamp and in the first passage;
• and
• the second modular portion having:
• a post extending from the body away from the lower surface and having a second longitudinal axis that is parallel to the first longitudinal axis, the post having a partially spherical outer surface,
• wherein the legs of the clamp of the first securing mechanism do not extend beyond the lower surface of the body when the securing mechanism is in the unlocked position and the locked position,
• wherein the two opposing legs move inwardly toward one another as the clamp is driven upward in the body to the locked position by rotation of the set screw, and
• wherein the set screw is able to rotate independently from the clamp.
