Long bone fractures are common injuries caused by trauma. Some studies have demonstrated that ultrasound has a high sensitivity and specificity in the diagnosis of upper and lower extremity long bone fractures.
The aim of this study was to determine the accuracy of ultrasound compared with plain radiography in diagnosis of upper and lower extremity long bone fractures in traumatic patients.
This cross-sectional study assessed 100 patients admitted to the emergency department of Imam Khomeini Hospital, Ahvaz, Iran with trauma to the upper and lower extremities, from September 2014 through October 2015. In all patients, first ultrasound and then standard plain radiography for the upper and lower limb was performed. Data were analyzed by SPSS version 21 to determine the specificity and sensitivity.
The mean age of patients with upper and lower limb trauma were 31.43±12.32 years and 29.63±5.89 years, respectively. Radius fracture was the most frequent compared to other fractures (27%). Sensitivity, specificity, positive predicted value, and negative predicted value of ultrasound compared with plain radiography in the diagnosis of upper extremity long bones were 95.3%, 87.7%, 87.2% and 96.2%, respectively, and the highest accuracy was observed in left arm fractures (100%). Tibia and fibula fractures were the most frequent types compared to other fractures (89.2%). Sensitivity, specificity, PPV and NPV of ultrasound compared with plain radiography in the diagnosis of upper extremity long bone fractures were 98.6%, 83%, 65.4% and 87.1%, respectively, and the highest accuracy was observed in men, lower ages and femoral fractures.
The results of this study showed that ultrasound compared with plain radiography has a high accuracy in the diagnosis of upper and lower extremity long bone fractures.
长骨骨折是由创伤引起的常见损伤。一些研究表明，超声在诊断上下肢长骨骨折方面具有较高的敏感性和特异性。
本研究旨在确定与X线平片相比，超声诊断创伤患者上下肢长骨骨折的准确性。
这项横断面研究评估了2014年9月至2015年10月期间因上下肢创伤入住伊朗阿瓦士伊玛目霍梅尼医院急诊科的100例患者。对所有患者首先进行超声检查，然后对上下肢进行标准X线平片检查。采用SPSS 21版软件分析数据以确定特异性和敏感性。
上肢和下肢创伤患者的平均年龄分别为31.43±12.32岁和29.63±5.89岁。与其他骨折相比，桡骨骨折最为常见（27%）。超声与X线平片相比，诊断上肢长骨骨折的敏感性、特异性、阳性预测值和阴性预测值分别为95.3%、87.7%、87.2%和96.2%，在左臂骨折中观察到最高准确性（100%）。与其他骨折相比，胫骨和腓骨骨折最为常见（89.2%）。超声与X线平片相比，诊断上肢长骨骨折的敏感性、特异性、阳性预测值和阴性预测值分别为98.6%、83%、65.4%和87.1%，在男性、低年龄组和股骨骨折中观察到最高准确性。
本研究结果表明，与X线平片相比，超声在诊断上下肢长骨骨折方面具有较高的准确性。
