Abstract
The implant fixation systems disclosed herein include an implant manufactured with, or coupled to, one or more implant fixation devices used to secure the implant to bone. Various implant fixation device embodiments have an engagement element with a concave engagement tip, a guiding element defining a planned trajectory along which the engagement element is configured to move, and an adjustment element configured to move the engagement element along the planned trajectory. Moving the engagement element along the planned trajectory causes the concave engagement tip to enter a bone in a first position and rotate within the bone to a second position. Continuing to move the engagement element along the planned trajectory may cause the concave engagement tip to undergo translational movement from the second position to a third position, thereby pulling the implant towards the bone and exerting compression forces on the bone.
