The authors report one case of overriding impacted symphysis by lateral compression injury of the pelvis. A 30 year old male presented a disruption of the symphysis pubis following a motor vehicle accident with lateral injury. Radiographs of the pelvis revealed a displacement of the right part of the symphysis behind the left one and a protrusion of the left pubic body through the right obturator foramen. CT scan did not show any sacro-iliac disruption but a fracture of the lateral part of the sacrum. An urethral injury with a complete urethral disruption was associated. Open reduction and internal fixation was necessary to reduce displacement. Urethral disruption was treated after retrograde urethrogram, four months after injury. Two years after injury, there was no pain in the pelvis and urinal function was normal. A sexual dysfunction remained. This lesion is secondary to lateral compression injury with internal rotation of the right part of the pelvis. It can be classified in type B2 of Tile's classification. It is a rare condition because this mechanism very often leeds to a fracture of the pelvic ring.
