1. An aiming arm system, comprising:
an aiming arm having 1) an aiming arm body and a guide hole that extends through the aiming arm body along a central guide hole axis, wherein the aiming arm is configured to be positioned such that the central guide hole axis is aligned with a target location of an anatomical implant, and 2) a retention element supported relative to the aiming arm body; and
a guide sleeve that extends along a linear central guide sleeve axis, the guide sleeve sized to be inserted into the guide hole, wherein relative rotation between the guide sleeve and the retention element transitions the aiming arm system between an unlocked configuration whereby the guide sleeve is movable in the guide hole along the central guide hole axis, and a locked configuration whereby the retention element applies a retention force to the guide sleeve that resists movement of the guide sleeve along the central guide hole axis, wherein the guide sleeve is an outer guide sleeve, and has an inner guide surface that defines an outer guide aperture that extends through the outer guide sleeve along the central guide sleeve axis, wherein the inner guide surface includes a first coupler, the system further comprising:
an inner guide sleeve that extends along a central inner guide sleeve axis, the inner guide sleeve sized to be inserted into the outer guide aperture, the inner guide sleeve having an outer guide surface that includes a second coupler,
wherein the first and second couplers are configured to couple to one another such that the inner guide sleeve is substantially prevented from moving within the outer guide aperture.
