Abstract: Objective：To observe the clinical value of the mini-incision outside the elbow joint for children with severe humerus supracondylar fracture.Methods：Totally 38 cases of severe humerus supracondylar fracture were chosen at the Hunan Children's Hospital between January 2012 and January 2015. The children underwent surgical treatment with mini incision outside the elbow and fixation with Kirschner wire. The efficacy was assessed by the Flynn standard during the 1 to 2-year follow-up.Results：The surgeries for children were all successful and the incision wound healed smoothly. The elbow function recovered well with an average bone healing time of (2.7±0.4)months. The total percentage of patients rated as excellent(26 cases) and good(8 cases) was 89.47%(34/38), and the other patients were rated as not good(3 cases) and bad(1 case). During the perioperative period and follow-up, no patient had elbow loosening, neurological vascular damage or cubitus varus.Conclusion：The mini-incision outside the elbow joint should be recommended as a surgical procedure for children with severe humerus supracondylar fracture, due to its good safety, minor wound, simple operation and low expense.
