A system for accurate closed reduction and external fixation of fractures

A new external reduction and fixation system has been developed in which the two processes are carried out by two pieces of apparatus - a reducer and a fixator. Schanz pins are inserted into the fractured bone in the conventional way and the reducer, which is free-standing, is placed adjacent to the limb and attached to the pins. During reduction the proximal bone segment remains stationary while the distal segment is moved to realign the bone. Its movements are carried out mechanically by the reducer and each plane is dealt with separately, the bone segment being moved both linearly and in rotation in that plane. Each movement is obtained by turning one of the three handles on the reducer, and is smoothly and rapidly accomplished with complete control. Once the best possible alignment has been achieved a simple, lightweight, single-side fixator is attached to the pins. The reducer is then unfastened and removed.
