Abstract Objective To compare the clinical effects of intramedullary elastic reduction of the “de-sharpened Kirschner wire and traditional three-dimensional manipulation in the treatment of Gartland type III posterolateral supracondylar fracture of the humerus in children. Methods A retrospective cohort analysis was made on 106 cases of Gartland type III posterolateral supracondylar fracture of the humerus treated in the Department of Orthopaedics of a Children’s Hospital from March 2020 to March 2022. According to different surgical technology, the patients were divided into two groups: intramedullary elastic reduction of the de-sharpened Kirschner wire group (experimental group, n = 50) and traditional three-dimensional manipulation group (control group, n = 56). The surgical operating time, intraoperative fluoroscopy times, postoperative Baumann angle changes, postoperative elbow function Flynn score, and complications were collected and compared between the two groups. Results All the enrolled cases underwent surgery successfully and were followed-up at least 6 months. The surgical operating time of the experimental group was 32.88 ± 3.69 min and that of the control group was 45.56 ± 10.13 min, and the difference was statistically significant (P 0.5). There were no complications such as osteomyelitis, compartment syndrome, iatrogenic vascular and nerve injury, and myositis ossificans in either group. Conclusions Good functional outcome can be obtained with both intramedullary elastic reduction of the de-sharpened Kirschner wire and traditional three-dimensional manipulation for Gartland type III posterolateral displaced supracondylar fracture of the humerus in children; however, the former does not need repeated manipulation, and the operation time is shorter, the number of intraoperative fluoroscopy is less, and the recovery of the Baumann angle is better.
