LATERAL COMPRESSION (LC) INJURIES 

The hallmark of this injury is a transverse fracture of the pubic ramus (or rami), often best seen on an inlet view x-ray. There may also be a compression fracture of the sacrum. In its simplest form this would be classified as a LC-I injury. The ring is stable.

The LC-II injury is more severe; in addition to the anterior fracture, there may be a fracture of the iliac wing on the side of impact. However, the ring remains stable.

The LC-III injury is worse still. As the victim is run over, the lateral compression force on one iliac wing results in an opening anteroposterior force on the opposite ilium, causing injury patterns typical for that mechanism.

侧压（LC）损伤

这种损伤的特征是耻骨支（或分支）的横向骨折，通常最好在入路x线片上看到。也可能是骶骨压缩性骨折。在最简单的情况下，这将被归类为LC-I损伤。戒指是稳定的。

LC-II损伤较重，除前部骨折外，撞击侧可能有髂翼骨折。然而，环仍然保持稳定。

LC-III损伤更严重。当受害者被碾过时，一侧髂翼上的侧向压缩力会导致对侧髂骨产生开放性的前后向力，造成典型的损伤模式。
