As it is mentioned in many studies that one major advantage of the backward sliding mechanism of lag screw is controlled compression of fracture with weight bearing which helps in healing of fracture.
正如多数研究所提到的拉力螺钉的一个主要优点是反向滑动机制，能在负重条件下对骨折施加控制性加压，促进骨折的愈合。
Objective: to provide anatomical basis for the placement of lag screw in the acetabular anterior column.
目的：为髋臼前柱拉力螺钉内固定提供解剖学基础。
Placement of an anteroposterior lag screw can also be complicated by screw traffic if there are a large number of screws fixing the primary fracture.
如果对骨折进行大量前后位固定的话，螺钉的位置安置也是问题。
