<p num="1"><br/><br/><br/>An aiming guide aligns a surgical tool with a hole in a bone plate. The aiming <br/>guide includes an arm portion having a longitudinal axis, top and bottom <br/>surfaces, and first and second ends. The aiming guide further includes a <br/>handle portion having upper and lower ends. The handle portion is, at its <br/>lower end, connected to the bone plate. The handle portion is, at its upper <br/>end, connected to the arm portion. Bores extend from the top surface to the <br/>lower surface of the arm portion. Each bore is configured and dimensioned to <br/>receive a tool guide in at least two different preset positions which locates <br/>the channel in at least two different hole positions. The bore includes two <br/>diametrically opposed slots extending along at least a portion of a length of <br/>the bore, the slots configured and dimensioned to mate with diametrically <br/>opposed knobs extending radially outward from a tool guide. The tool guide has <br/>a head and a sleeve portion, which has a centered channel. The sleeve portion <br/>and channel are eccentric with respect to the head portion. The tool guide is <br/>inserted in a first preset position in order to align a surgical tool with one <br/>portion of a two-portion bone plate hole, or in a second preset position <br/>rotated 180~ from the first preset position, in order to align a surgical tool <br/>with the second portion of a two-portion bone plate hole.<br/> |
