前臂牵引台——一种新的牵引装置

The forearm traction instrument —a new traction device

桡骨远端不稳定骨折的治疗不论采用内固定或外固定方式,首先都要进行牵引复位,以恢复桡骨远端的长度、关节面的完整和关节的相对应关系。复位效果常常与牵引是否充分、有效密切相关。作者研制的前臂牵引台,简单、易操作,牵引效果可靠,为桡骨远端不稳定骨折手术治疗提供了稳定、持续、有效的牵引。在C型臂透视配合下,为术中骨折复位、固定提供了一个稳定的环境,有利于手术操作,缩短手术时间,提高手术质量,减少术者与X线的接触。操作中也应该注意避免牵引时间过长、过牵和暴力牵引。通过作者的临床使用经验,前臂牵引台是治疗桡骨远端不稳定骨折的一种有效的辅助器械。

Traction during reduction is essent ial for internal or external fixatio n of unstable distal radial fractures.Adequate and effective t raction is the key to the restoration of articular congruence,normal joint relation and the length of distal radius.The f orearm traction instrument develop ed by the authors is a simple,versatile and reliable device,from which stable,continuous and effective traction c an be expected during the surgery.The traction instrument is connected wi th the surgery-table before the operation.According to the needs of diff erent operations,many kinds of traction could be perfo rmed to support the operation.With t he help of the device,frac-ture reduction and fixation is signi ficantly improved during the surgery without excessively violent traction.The X-ray exposure and the operation hou rs can also be decreased as well.Over-traction or long-time violent traction could be avoided during the surgery.According to the author' s experience,the forearm traction i nstrument is an effective implemental device in the treatment of the unstable fractures of distal radius.[
