1. A system for bone fixation, comprising:
an instrument defining a guide axis and configured to be coupled to a bone such that the guide axis extends across the bone;
a bushing configured to be placed at least partially into at least one hole bored in the bone along the guide axis;
a nail configured to be placed along a medullary canal of the bone such that the nail extends through the bushing; and
a locker configured to lock the nail to the bushing,
wherein the instrument includes:
a guide portion defining the guide axis; and
one or more wire-receiving channels, wherein the one or more wire-receiving channels are separate from the guide portion,
wherein the one or more wire-receiving channels are configured to receive one or more wire members and direct the one or more wire members into the bone, to couple the instrument to the bone with the one or more wire members,
wherein the one or more wire-receiving channels are configured to direct a leading end of the one or more wire members on a trajectory through the bone that avoids the space in the medullary canal to be occupied by the nail,
wherein the one or more wire-receiving channels comprise:
a first wire-receiving channel having a first trajectory and configured to receive a first wire member; and
a second wire-receiving channel having a second trajectory and configured to receive a second wire member,
wherein a portion of the first trajectory overlaps with a portion of the second trajectory when viewed from the top of the instrument.
