1. A surgical instrument for simultaneously engaging, aligning and maintaining displaced bone fragments of a fractured bone together in a reduced position in order to facilitate preparation and placement of a bone fixation device in an axis perpendicular to a fracture line between the bone fragments, the instrument comprising:
first and second lever arms pivotally attached to one another, wherein each of the first and second arms have a proximal end having a handle and an arm locking mechanism, and each of the first and second arms have a distal end with an engaging tip configured to grip the fractured bone fragments without interfering with the preparation and placement of the bone fixation device, wherein the arm locking mechanism is configured to hold the engaging tips in a desired position relative to the bone fragments in order to maintain the fractured bone in a reduced position, an alignment guide movably attached to one of the lever arms, wherein the alignment guide is movably mounted on the lever arm for rotation through multiple axes, and a removable guide sleeve for the alignment guide to guide the orientation of drill bits, tap tools, countersink tools, and the like used to prepare the bone fragments for placement of the fixation device along the axis perpendicular to the fracture line and as close as possible to an axis parallel with an axis through the engaging tips of the lever arms. |
