Abstract: Abstract: Objective: To determine the usefulness of closed reduction and internal ?xation（CRIF）as the initial treatment for completely displaced and rotated fractures of the lateral condyle of the humerus in children. Methods: We prospectively studied 51 completely displaced and rotated lateral condylar fractures of the humerus in children (JAKOB Stage 3, 40 boys and 11 girls) that were treated by three different surgeons from 2007 to 2011. In 51 fractures, we initially attempted CRIF. We assessed the preoperative degree of displacement and postoperative radiographic quality of CRIF. Clinical results were graded using the criteria suggested by Hardacre et al. Results: Three fractures were treated with ORIF initially because of lack of experience with it. Closed reduction to within 2 mm failed in eleven fractures, so ORIF was then performed. 37 of 51 (72.5%) completely displaced and rotated fractures were reduced within 2 mm of residual displacement using the CRIF. There were no signi?cant complications such as limited range of motion, pain, osteonecrosis of the trochlea or capitellum, nonunion, malunion, or early physeal arrest. Conclusion: CRIF is an effective treatment for completely displaced and rotated lateral condyle fractures of the humerus in children.
