Kirschner Wire Prying and Leverage Technique—— A New Closed Reduction Method in the Treatment of Pediatric “Irreducible Supracondylar Humerus Fractures”

Abstract Objective This paper is aiming at introducing a new closed reduction method in the treatment of pediatric“Irreducible Supracondylar Humerus Fractures”.And making a clear definition of this type of fracture. Study design The sample of our study is the 120 cases of “Irreducible Supracondylar Humerus Fractures” treated surgically in our department. We classified them into two groups according to the methods being used in the treatment.Group 1 referred to the cases that were fixed by Closed reduction and percutaneous pinning(CRPP), while group 2 were treated by Kirschner wire prying and leverage technique combined with CRPP.Then we collected and evaluated relative data of two groups during the follow-up. Results The operative time and intraoperative fluoroscopy times of group 2 were significantly shorter than those of the group 1, and the percentage of open reduction in group 1 was significantly higher than that of group 2. Meanwhile, age, time from injury to surgery, and initial deviation of the distal fragment were the risk factors that leads to the failure of closed reduction. Conclusion We reached a conclusion that CRPP with kirschner wire prying and leverage technique is safe and effective in the treatment of “Irreducible Supracondylar Humerus Fractures”. This new method can significantly shorten the operation time, reduce the number of intraoperative fluoroscopy times, and lower the percentage of open reduction without increasing the risk of complications.
