Aims To evaluate the accuracy of ultrasound in pediatric distal forearm fractures as well as the effect on the ED waiting time for these patients. Methods Convenience sample of 42 pediatric patients presented with wrist injury. All patients underwent US examination followed by 2-views radiographs of the wrist with recording the time to US. In addition, the time to X-ray were calculated, retrospectively, on 95 pediatric patients for comparison. Results Forty-two patients were examined, 25 males (60%) and 17 females (40%), mean age 7.2 years. On X-Ray, 30 patients (71%) were confirmed to have a distal forearm fractures, of which, 28 (93%) were diagnosed by US. The sensitivity of ultrasound diagnosis was 93.3% (95% CI, 83%-100%), and the specificity was 92% (95% CI, 76%-100%). The positive and negative likelihood ratios were 11.6 and 0.07, respectively. Conclusions Ultrasound is a reliable diagnostic tool in the diagnosis of distal forearm fractures in children. Ultrasound has radiation free and decreases the length of stay in ED.
目的 评估超声在小儿前臂远端骨折诊断中的准确性以及对这些患者急诊等待时间的影响。方法 对42例因腕部损伤就诊的小儿患者进行便利抽样。所有患者均接受超声检查，随后进行腕部双视图X线摄影，并记录超声检查时间。此外，回顾性计算95例小儿患者的X线检查时间以作比较。结果 共检查42例患者，其中男性25例（60%），女性17例（40%），平均年龄7.2岁。X线检查显示，30例患者（71%）确诊为前臂远端骨折，其中28例（93%）经超声诊断。超声诊断的敏感性为93.3%（95%可信区间，83%-100%），特异性为92%（95%可信区间，76%-100%）。阳性似然比和阴性似然比分别为11.6和0.07。结论 超声是诊断小儿前臂远端骨折的可靠诊断工具。超声无辐射，可缩短急诊留观时间。
