Fracture of the transverse process of the fifth lumbar vertebra is caused by traction through the iliolumbar ligament by the vertically and proximally or medially dislocated hemipelvis. This fracture is therefore associated with the vertical shearing force of Malgaigne's fracture-dislocation of the pelvis or the lateral crush fracture-dislocation of the pelvis. In the absence of evidence on a radiograph of a fracture through the sacroiliac area or dislocation or subluxation of the sacroiliac joint, the fracture of the transverse process of the fifth lumbar vertebra may be the only radiological evidence for posterior instability of the ipsilateral hemipelvis.
第五腰椎横突骨折是由垂直向近端或内侧脱位的半侧骨盆通过髂腰韧带的牵拉所致。因此，该骨折与马尔盖涅骨盆骨折脱位的垂直剪切力或骨盆外侧挤压骨折脱位相关。在骶髂区域X线片上没有骨折证据，或骶髂关节没有脱位或半脱位的情况下，第五腰椎横突骨折可能是同侧半侧骨盆后方不稳定的唯一影像学证据。
