目的调查儿童桡骨远端骨折闭合复位后再移位发生率及其相关风险因素。方法 251例桡骨远端骨折患者,分为移位组(71例)和非移位组(180例),比较两组患者人口统计学资料和临床变量,评估危险因素包括年龄、性别、桡骨远端骨折的位置、术前骨折移位、尺骨骨折的存在、复位效果、术者水平、石膏类型、石膏的质量,及复位后移位畸形。结果 39例(28.3%)骨折复位后发生再移位,早期完全移位是再移位最重要的危险因素[(OR 6.13,95%CI(2.29,21.37),P<0.05)],且解剖复位的实现可降低再移位的风险[(OR 0.38,95%CI(0.11,1.12)],P<0.05)。结论完全移位的桡骨远端骨折不能完成解剖复位者存在闭合复位后再移位的高风险。
Objective To investigate the incidence of re-displacement and its related risk factors after closed reduction of distal radius fractures in children. Methods A total of 251 patients with distal radius fractures were divided into shift group (n = 71) and non-shift group (n = 180). Demographic data and clinical variables were compared between the two groups. Risk factors including age, sex, The location of the end fracture, the displacement of the preoperative fracture, the presence of the ulna fracture, the reset effect, the level of the surgeon, the type of gypsum, the quality of the gypsum, and the displacement deformity after the reset. Results All the 39 cases (28.3%) were re-displaced after the fracture reduction. The early complete displacement was the most important risk factor of re-transposition (OR 6.13, 95% CI 2.29, 21.37, P <0.05) The reduction achieved a reduction in the risk of re-transposition [(OR 0.38, 95% CI (0.11, 1.12)], P <0.05). Conclusion The complete displacement of distal radius fractures can not be completed anatomic reduction there is a high risk of re-displacement after the closure of the reset.
