Abstract：
UNASSIGNED: Ultrasound-guided manipulation and reduction (M&R) of the distal radius fractures (DRF) is believed to improve radiographic indices due to real-time feedback of fracture alignment. The objective of this trial was to compare volar tilt, radial inclination, and radial height on radiographs between Ultrasound guided and conventional (landmark-guided) M&R.
UNASSIGNED: A total of 79 distal radius extraarticular fractures in adults were randomised to Ultrasound guided and conventional (landmark-guided) M&R. The radiograph parameters described above were compared before and after M&R in both groups.
UNASSIGNED: Except for volar tilt (P=0.05 difference in difference), there was no difference in both the groups on radiograph parameters i.e. radial inclination and radial height. We estimated a reduction in the incidence of malreduction by 49% (Risk ratio 0.51) and an absolute risk reduction of 22% through USG-guided reduction. We evaluated a number needed to treat 4 through USG-directed M&R of DRF to prevent one unacceptable reduction. There were 9 (22%) and 18 (46%) (P=0.70) unacceptable reductions in USG-guided and landmark-guided M&R.
UNASSIGNED: Adding USG guidance to conventional landmark-based closed reduction methods is not beneficial for the accuracy of fracture reduction in Colle\'s fracture. However, improved volar tilt in sonographic-directed M&R needs further studies to determine the clinical significance.

摘要：
■由于骨折对齐的实时反馈，超声引导下桡骨远端骨折（DRF）的操作和复位（M＆R）被认为可以改善影像学指标。这项试验的目的是比较掌侧倾斜，径向倾角,超声引导和常规（地标引导）M＆R之间的X射线照片上的径向高度。
■共有79例成人桡骨远端关节外骨折被随机分为超声引导和常规（界标引导）M&R。比较两组在M&R之前和之后的上述X线照片参数。
■除了掌侧倾斜（P=0.05差异），两组的X线摄影参数即径向倾角和径向高度没有差异.我们估计，通过USG指导的减少，减少不良的发生率降低了49％（风险比0.51），绝对风险降低了22％。我们评估了通过USG指导的DRFM＆R治疗4所需的数量，以防止一种不可接受的减少。在USG指导和地标指导的M＆R中，有9（22％）和18（46％）（P=0.70）个不可接受的减少。
■在常规的基于界标的闭合复位方法中添加USG指导对于Colle\的骨折复位的准确性没有好处。然而,超声引导的M＆R中改善的掌侧倾斜需要进一步研究以确定其临床意义。
