Abstract
A bone fixation assembly for securing a fixation device such as a bone plate, to bone includes a fixation device including a through hole; a bushing having a sidewall with a bore and a slot; a fastening screw with a threaded shaft and a head including a recess; and a locking screw with a body capable of being threaded into the head of the fastening screw to expand its radial wall. In use, the bushing is seated within the through hole of the fixation device at a selected angle and the fastening screw is inserted through the bore of the bushing such that its head fits in the bushing and its shaft is threaded into bone. The locking screw may then be threaded into the head of the fastening screw to expand the radial wall of its head resulting in the locking of the fastening screw, and bushing at a selected orientation within the through hole.
