If the fracture is transverse, it may be reduced with manipulation using clamps on the bone ends. This may require excessive exposure. Percutaneous Schanz screws, or percutaneously applied pointed reduction forceps, as illustrated, are less invasive.
The technique with clamps is as follows:
Free up the ends of both fracture fragments. Align the crest of both fragments. This will assure proper rotation.
Flex the fracture to 45 degrees, or enough to place one fragment onto the other. Approximate the cortical edges, and gradually straighten the fracture, which compresses the fracture site. Recheck alignment.
