We report on a convenient intraoperative distraction technique, called the modified Dynamic Wire-framed Traction (mDWT) method, that assists in fracture reduction and/or is used as an external fixator in patients with unstable distal radius fractures and in other hand and forearm fractures. The mDWT device is easily assembled with wires at the time of surgery, and its configuration produces sufficient longitudinal distraction force that makes reduction easier and facilitates additional fixation procedures. Furthermore, the device can be converted into a simple unilateral external fixator that can be retained postoperatively. Our experience with 13 patients shows that the mDWT method is easy to apply and is a cost-effective technique when used as an intraoperative distraction device or as an external fixator.
我们报告了一种简便的术中牵引技术，称为改良动态钢丝框架牵引（mDWT）法，该技术有助于不稳定桡骨远端骨折患者及其他手部和前臂骨折患者的骨折复位和/或用作外固定器。mDWT装置在手术时易于用钢丝组装，其结构可产生足够的纵向牵张力，使复位更容易并便于进行额外的固定操作。此外，该装置可转换为简单的单侧外固定器，术后可保留。我们对13例患者的经验表明，mDWT法易于应用，作为术中牵引装置或外固定器使用时是一种经济有效的技术。
