[Objective] To introduce the surgical technique and preliminary clinical results of closed reduction and internal fixation with elastic intramedullary nail rocker technique for the treatment of distal radius metaphyseal junction fractures in children. [Methods] A total of 28 children with distal radius metaphyseal junction fractures were treated with closed reduction and internal fixation using elastic in- tramedullary nail rocker technique. Under fluoroscopy, the "safe zone" of the proximal radius was located and marked with Kirschner wire or hemostatic forceps. A incision was made over the zone center to expose to the radius. An intramedullary nail selected in proper size and bended in shape was inserted into medullary cavity through an opening, and with controlling the handle of the nail to complete the coronal reduction of the fracture at the distal end. If there was still rotational displacement of the fracture, the "rolling pin" technique was used to correct it. [Results] All the 28 children were successfully operated on without serious complications, and followed up for 6 to 18 months, with an average of (8.4±4.6) months. At the latest follow-up, range of motion, grip strength, and local pain were significantly improved in all children. The modified Mayo scores ranged from 80 to 100, with an average of (92.6±7.9) at the latest follow up. The clinical results were marked as excellent in 20 cases and good in 8 cases, with the excellent and good rate of 100%. [Conclusion] The closed reduction and in- ternal fixation with elastic intramedullary nail rocker technique is minimally invasive, simple, safe for the treatment of distal radius metaph- yseal junction fractures in children.
