A method includes inserting a bone fixation device into a patient's body.
The bone fixation device includes a first member and a second member
movably coupled to the first member. A passageway is defined within a
bone tissue after the bone fixation device is inserted and while the bone
fixation device is disposed within the patient's body. At least a portion
of the first member of the bone fixation device is disposed within the
bone tissue along the passageway. The second member of the bone fixation
device is moved relative to the first member of the bone fixation device.
