SUPREME DISTRACTER

Abstract

A fixation device for internally or externally fixing fractures comprising at least one nitinol wire having an S-shaped section and two ends wherein each of said two ends forms a hook for hooking into a bone section of a fractured bone. This device can be made from nitinol, which has a transformation temperature between 25 DEG C, and 35 DEG C. In addition, this device can have a diameter between 0.6 mm and 5mm. The device can be inserted using the following process, which starts by cooling the wire to below a transfer temperature such that the nitinol wire forms in a martensite state. Next, the nitinol wire is inserted into an interphalangeal bone underneath a patient's skin. Next, the nitinol wire to heats up inside a patient's body above the transfer temperature.; Finally, the wire transforms wire from a martensite state to an austenite state wherein when the nitinol wire elongates in a longitudinal direction to generate a distraction force.
