ABSTRACT:
A fracture reducing apparatus for achieving and maintaining fracture reduction having three side arms which are threadedly connected to two main arms. A knob pivotally connects the two main arms and maintains their relative position with respect to one another. The side arms of the apparatus distribute the surgeon's manipulating force to three points along the surface of the fractured limb and when the reduction is achieved, the knob is tightened to maintain the reduction, thus freeing surgeon's hands to apply the fixation, or to completely move out of the field of x-ray exposure.
