Abstract
A coupling device for coupling a rod to a bone anchor includes a receiving part configured to receive a head of the bone anchor, the receiving part having a first end and a second end, a central axis that extends between the first and second ends, and two legs at the first end that define a recess extending in a longitudinal direction transverse to the central axis for receiving the rod, and a monolithic pressure member positionable in the receiving part, the pressure member including a rod support surface and an engagement portion to adjust the pressure member to exert pressure on the head. The engagement portion is positioned farther radially from the central axis in the longitudinal direction than a first portion of the rod support surface, and extends closer axially to the first end of the receiving part than the entire first portion of the rod support surface.
