ABSTRACT:
A suture-wire device for fracture fixation is composed of a metal pin and a segment of wire. The anterior part of the device is a metal pin with sharp tip and a hole at the end where one segment or multiple segments of flexible wire is connected. The wire is embedded in the hole and tightly fixed by mechanical methods into one piece. An impactor is a metal cylinder with conical end having a trough which is slightly wider than the diameter of wire along the core of the impactor. After reduction of the fracture, two suture-wires are drilled across the fracture line in parallel. The impactor is applied onto a blunt end of the pin with the wire in the trough. The remaining part of the pins are then hammered into the bone by applying a force to the impactor. One of the wires of the two suture-wires is then bent and looped behind the tips of the pins which protrude from the other end of fractured bone. The two wires are then brought together and tightened, and the protruding ends of the pins are cut.
