An implant assembly device for use in inserting a bone fixation implant includes: (a) a handle portion for manipulation by a user and (b) a shaft having a proximal end and a distal end. The proximal end of the shaft connected to the handle portion. The distal end of the shaft includes a screw engaging portion configured and adapted to engage and rotate a connecting screw. The device also includes (c) an elongated rod extended through the shaft from a proximal end to a distal end thereof The proximal end of the elongated rod is non-movably coupled to the shaft and the distal end of the elongated rod extending distally past of the distal end of the shaft. The elongated rod is configured and dimensioned to simultaneously pass through an interior portion of, and support, an implant insertion handle, the connecting screw and the bone fixation implant.
