Background Closed reduction is of great benefit for fracture healing. However, achieving this without sacrificing the reduction accuracy and exposing the surgeon and patient to excessive radiation is difficult. Methods A novel parachute guiding system (ParaEx System) was developed for closed reduction of fractures based on computed tomography data. The system included two counter guides with stainless tubular markers that could be attached to the unilateral external fixator. Comminuted tibial diaphyseal fracture models were used to validate the ParaEx System. Results The mean errors (and standard deviations) of residual rotational and translational deformity were 0.67° ± 0.45°, 0.92° ± 1.00°, and 0.64° ± 0.50° in rotation and 1.30 ± 1.10 mm, 1.13 ± 0.70 mm, and 0.94 ± 0.92 mm in translation about the X, Y, and Z axes of the local coordinate axes, respectively. Conclusions The ParaEx System was useful for accurate closed reduction of fractures at low cost. Copyright © 2013 John Wiley & Sons, Ltd.
