A bone fixation assembly comprising: a bone fixation plate defining at least two apertures, each aperture including an outer unthreaded region and an inner threaded region, the outer unthreaded regions defining a cross-sectional dimension that is greater than a cross-sectional dimension of the inner threaded regions; at least one permanent bone fixation member having a cross-sectional dimension such that the permanent bone fixation member is configured to be driven into one of the at least two apertures and into an underlying bone so as to permanently affix the bone fixation plate to the underlying bone; a temporary fixation wire (24; 124; 224) that is longitudinally elongate along a longitudinal axis, the temporary fixation wire (24; 124; 224) including a wire body (26; 126; 226) that has a cross-sectional dimension less than the cross-sectional dimension less of the permanent bone fixation member, characterized in that the temporary fixation wire (24; 124; 224) further includes an abutment member (32; 132; 232) that extends out from the wire body (126; 226) such that the abutment member (32; 132; 232) defines a distal surface (41; 141; 241) that extends out from the wire body (26; 126; 226) along a transverse direction that is perpendicular with respect to the longitudinal axis, a proximal surface (39; 139; 239) that extends out from the wire body (26; 126; 226) along the transverse direction, and an intermediate surface (43; 143; 243) extending longitudinally between the proximal surface (39; 139; 239) and the distal surface (41; 141; 241), a portion of the intermediate surface (43; 143; 243) having a cross-sectional dimension that is equal to the cross-sectional dimension of the outer unthreaded regions, wherein insertion of the temporary fixation wire (24; 124; 224) into a select one of the at least two apertures causes the abutment member (32; 132; 232) to temporarily compress the bone fixation plate against the underlying bone, such that the temporary fixation wire (24; 124; 224) prevents movement of the bone fixation plate relative to the underlying bone prior to subsequent permanent fixation of the bone fixation plate to the underlying bone. a bone fixation plate defining at least two apertures, each aperture including an outer unthreaded region and an inner threaded region, the outer unthreaded regions defining a cross-sectional dimension that is greater than a cross-sectional dimension of the inner threaded regions; at least one permanent bone fixation member having a cross-sectional dimension such that the permanent bone fixation member is configured to be driven into one of the at least two apertures and into an underlying bone so as to permanently affix the bone fixation plate to the underlying bone; a temporary fixation wire (24; 124; 224) that is longitudinally elongate along a longitudinal axis, the temporary fixation wire (24; 124; 224) including a wire body (26; 126; 226) that has a cross-sectional dimension less than the cross-sectional dimension less of the permanent bone fixation member, characterized in that the temporary fixation wire (24; 124; 224) further includes an abutment member (32; 132; 232) that extends out from the wire body (126; 226) such that the abutment member (32; 132; 232) defines a distal surface (41; 141; 241) that extends out from the wire body (26; 126; 226) along a transverse direction that is perpendicular with respect to the longitudinal axis, a proximal surface (39; 139; 239) that extends out from the wire body (26; 126; 226) along the transverse direction, and an intermediate surface (43; 143; 243) extending longitudinally between the proximal surface (39; 139; 239) and the distal surface (41; 141; 241), a portion of the intermediate surface (43; 143; 243) having a cross-sectional dimension that is equal to the cross-sectional dimension of the outer unthreaded regions, wherein insertion of the temporary fixation wire (24; 124; 224) into a select one of the at least two apertures causes the abutment member (32; 132; 232) to temporarily compress the bone fixation plate against the underlying bone, such that the temporary fixation wire (24; 124; 224) prevents movement of the bone fixation plate relative to the underlying bone prior to subsequent permanent fixation of the bone fixation plate to the underlying bone.
