[Definitions and explanations on the topic of fracture reduction]

The process of reduction is a key step for successful fracture treatment. The goal of fracture reduction is the realignment of the displaced fractured fragments caused by muscle tension or impaction back into the original anatomic relationship. The reduction process includes not only the application of force at or remote from the fracture site to reverse the deforming forces but also the preoperative planning where to apply these forces and by what means. Furthermore, consideration should be preoperatively given on how to position the patient and the C‑arm and how to temporarily maintain reduction for intraoperative x‑ray control of the axis, rotation and lengths before definitive fixation.
