Certain acetabular fractures may necessitate distraction of the hip joint for removal of intra-articular debris and assessment of reduction. Distraction can be accomplished by manual traction, using a traction table or an AO universal manipulator (UM). The UM is a relatively simple and an inexpensive device that can provide focal distraction in a controlled manner without the risks associated with the use of a traction table. We describe a technique using the UM for hip joint distraction during acetabular fracture surgery through a Kocher-Langenbeck surgical exposure.
某些髋臼骨折可能需要对髋关节进行牵引，以清除关节内碎片并评估复位情况。牵引可通过手动牵引、使用牵引床或AO通用操纵器（UM）来完成。UM是一种相对简单且价格低廉的设备，它能够以可控方式提供局部牵引，而不存在使用牵引床相关的风险。我们描述了一种在髋臼骨折手术中，通过Kocher-Langenbeck手术入路使用UM进行髋关节牵引的技术。
