Medial epicondyle fractures a prevalent injury, constituting 11% to 20% of all elbow fractures in children and adolescents. Common fixation strategies for displaced medial epicondylar fractures involve the use of K-wires and Lag-Screw fixation. The aim of this retrospective study was to compare 2 methods for treating medial epicondylar fractures in children. In this retrospective study, 26 children with displaced medial epicondyle fractures were included. Patients were divided into 2 groups after reduction: Lag-Screw (LS) group and K-wires group. We compared the operation time, range of motion (ROM), range of rotation (ROR), and Mayo elbow performance score (MEPS). A total of 26 patients were available for a long-term follow-up, with a mean age of 11.6 ± 2.5 years, follow up by 35.7 ± 5.7 months. The average operation time in K-wires group was shorter than the Lag-Screw group. The average ROM, ROR, and MEPS of the 2 groups are excellent in 3 months follow up after operation and maintained excellent results during the final follow-up. Regarding MEPS, ROM, and ROR, there was no significant difference between LS group and KW group. However, the LS group experienced fewer complications than the KW group. Both Lag-Screw and K-wires fixation for medial epicondyle fractures in pediatric patients yield favorable mid-term results when assessed in terms of ROM,ROR, MEPS. K-wires fixation, while having a shorter operation time and saving an additional anesthesia and surgery to remove the implants compare to fixed by Lag-Screw fixation, does come with a higher complication rate.
儿童和青少年肘部骨折中，占 11%至 20%的常见损伤为尺骨鹰嘴骨折。对于移位的尺骨鹰嘴骨折，常见的固定策略包括使用克氏针和 Lag-Screw 固定。本回顾性研究旨在比较两种治疗儿童尺骨鹰嘴骨折的方法。
在这项回顾性研究中，纳入了 26 例移位的尺骨鹰嘴骨折患者。患者在复位后分为两组：Lag-Screw（LS）组和 K-wires 组。我们比较了手术时间、关节活动度（ROM）、旋转活动度（ROR）和 Mayo 肘部功能评分（MEPS）。
共有 26 例患者获得长期随访，平均年龄为 11.6±2.5 岁，随访时间为 35.7±5.7 个月。K-wires 组的平均手术时间短于 Lag-Screw 组。两组术后 3 个月的 ROM、ROR 和 MEPS 均为优秀，最终随访时均保持优秀结果。
关于 MEPS、ROM 和 ROR，LS 组和 KW 组之间无显著差异。然而，LS 组的并发症发生率低于 KW 组。
当评估 ROM、ROR 和 MEPS 时，对于儿童患者的尺骨鹰嘴骨折，Lag-Screw 和 K-wires 固定均能获得良好的中期结果。与固定 Lag-Screw 相比，K-wires 固定虽然手术时间更短，并且可以节省一次麻醉和手术以去除植入物，但并发症发生率更高。
