Abstract：
OBJECTIVE: To explore clinical effect of precast curvature internal fixation with Kirschner needle in treating forearm fracture in children.
METHODS: From October 2019 to December 2022,32 children with forearm fractures were treated with precast curvature internal fixation with Kirkler\'s needles,including 25 males and 7 females,aged from 3 to 15 years old with an average of (8.0±0.5) years old,18 patients on the left side and 14 on the right side,24 patients with double fractures of radial and ulna,3 patients with Monteggia fractures,and 4 patients with Galeazzi fractures,and 1 patient with radial neck fracture of crooked cap. Operation time,intraoperative blood loss,C-arm fluoroscopy,fracture healing time and complications were recorded,and disabilities of arm,shoulder and hand (DASH) scale and Grace-Eversman forearm double fracture evaluation system were used to evaluate clinical efficacy of precast curvature internal fixation with Kirschner\'s needle for forearm fracture in children.
RESULTS: All 32 patients were followed up for 2 to 12 months with an average of (7.16±2.51) months. Intraoperative blood loss was (20.68±5.50) ml,C-arm fluoroscopy was(5.80±2.50),and operation time was (24.34±5.10) min,fracture healing time was (8.82±1.62) weeks. Two patients occurred complications,including postoperative rupture of extensor pollicis longus tendon in 1 patient and obvious displacement of fracture caused by rotation of prefabricated curvature Kirschler needle on bone marrow cavity in 1 patient. DASH scores ranged from 0 to 16 scores with an average of (8.32±1.50) scores. According to Grace-Eversman double fracture evaluation system,28 patients got excellent result,2 good and 2 fair.
CONCLUSIONS: The treatment of forearm fracture with Kirschner\'s needle prefabricated curvature internal fixation has advantages of less trauma,less bleeding,good reduction,stable fixation,fast fracture healing and good functional recovery.

摘要：
目的：探讨克氏针预制曲率内固定治疗儿童前臂骨折的临床效果。
方法：从2019年10月至2012年12月，32例前臂骨折患儿采用Kirkler针预制曲率内固定治疗，包括25名男性和7名女性，年龄在3至15岁之间，平均（8.0±0.5）岁，左侧有18名患者，右侧有14名患者，24例桡骨尺骨双骨折,3例Monteggia骨折患者，和4名Galeazzi骨折患者，1例桡骨颈弯曲帽骨折。操作时间,术中失血,C型臂透视检查,记录骨折愈合时间和并发症,和手臂残疾，采用肩手(DASH)量表和Grace-Eversman前臂双骨折评价系统评价克氏针预制曲率内固定治疗儿童前臂骨折的临床疗效。
结果：32例均获随访，随访时间2～12个月，平均(7.16±2.51)个月。术中出血量(20.68±5.50)ml,C臂透视结果为(5.80±2.50),手术时间(24.34±5.10)min,骨折愈合时间为(8.82±1.62)周。2例患者发生并发症,其中1例患者术后发生长伸肌腱断裂，1例患者骨髓腔预制弯曲克氏针旋转导致骨折明显移位。DASH评分为0~16分,平均(8.32±1.50)分。根据Grace-Eversman双骨折评价体系,28例患者取得优异成绩，2个好，2个公平。
结论：克氏针预制曲内固定治疗前臂骨折具有创伤小的优点，出血少,良好的还原，稳定的固定，骨折愈合快，功能恢复好。
