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