#$%^&*AU2006252075B220130926.pdf#####ABSTRACT A bone fixation assembly includes a side plate for mounting on a bone and a barrel for receiving a portion of a lag screw, and configured to be inserted into a hole in the side plate. A mechanical spring located at the upper portion of the barrel 5 biases a first detent portion toward a locking position with a second detent portion located on the side plate such that rotation of the barrel within the hole from a first position to a second position causes a compressing portion on the detent portion to contact a compressing portion on the second detent portion thereby compressing the mechanical spring so as to allow the barrel to be rotated to a third position wherein 10 the mechanical spring is allowed to bias the first detent portion into the locking position such that a retaining portion of the first detent is adjacent to a retaining portion of the second detent and rotation of the barrel with respect to the side plate is restricted. 04/12/06,16215 speci,21/8 ~~ lO 30 3 . 30 fILo FIG. 1
