1. An apparatus, comprising:
- a bone screw having a proximal end portion and a distal end portion, the distal end portion including a threaded portion; and
a retention member coupled to the proximal end portion of the bone screw such that movement of the retention member relative to the bone screw is limited, the retention member configured to deform when moved from a first configuration to a second configuration.

Abstract
An apparatus includes a bone screw and a retention member. The bone screw has a proximal end portion and a distal end portion. The distal end portion of the bone screw includes a threaded portion. The retention member is coupled to the proximal end portion of the bone screw such that movement of the retention member relative to the bone screw is limited. The retention member is configured to deform when moved from a first configuration to a second configuration.

12. An apparatus, comprising:
-
a first shaft having an engagement portion configured to engage a first engagement portion of a bone fixation device such that axial movement of the bone fixation device relative to the first shaft in a distal direction is limited; a second shaft having an engagement portion configured to engage a second engagement portion of the bone fixation device such that rotation of the second shaft results in rotation of the bone fixation device; and an actuator movably disposed about the second shaft, the actuator configured to deform a portion of the bone fixation device when the engagement portion of the first shaft is engaged with the first engagement portion of the bone fixation device and the engagement portion of the second shaft is engaged with the second engagement portion of the bone fixation device. - View Dependent Claims (13, 14, 15, 16)

17. A method, comprising:
-
inserting a bone fixation device into a body, the bone fixation device including a bone screw and a retention member, the retention member fixedly coupled to a proximal end portion of the bone screw; disposing at least a distal end portion of the bone screw within a passageway defined by a bone tissue; and deforming the retention member without moving the bone screw relative to the bone tissue, the disposing being independent from the deforming. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
