Abstract
In an embodiment, a system attaches a patient reference array of a computer-assisted surgery system to a patient. The system includes a fixation post having a shaft having proximal and distal ends that are offset from. A threaded fastener is coupled to the shaft at the distal end that rotates relative to the shaft so as to engage internal threads of a pedicle screw, thereby causing the distal end of the shaft to translate in the anchor seat and urge the pedicle screw to transition from an unlocked configuration to a locked configuration. The attachment assembly has an arm that supports the patient reference array, and a coupler supported by the arm. The coupler has a fixation body that defines a recess that receives at least a portion of the fixation post, and an actuator that secures the attachment assembly to the fixation post.
