DISRUPTION OF THE PUBIC SYMPHYSIS WITH OV ERRIDING IMPACTED SYMPHYSIS- A CASE-REPORT

Introduction The authors report one case of overriding impacted symphy sis by lateral compression injury of the pelvis. Material and methods A 30 year old male presented a disruption of the symphysis pubis follo wing a motor vehicle accident with lateral injury. Radiographs of the pelvis revealed a displacement of the right part of the symphysis behi nd the left one and a protrusion of the left pubic body through the ri ght 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 disr uption was treated after retrograde urethrogram, four months after inj ury. Results Two years after injury, there was no pain in the pelvis a nd urinal function was normal. A sexual dysfunction remained. Discussi on This lesion is secondary to lateral compression injury with interna l rotation of the right part of the pelvis. It can be classified in ty pe B2 of Tile's classification. It is a rare condition because this me chanism very often leeds to a fracture of the pelvic ring.
