The pelvic squeeze separation test is performed with the patient in supine position, and the examiner presses both sides of the anterior superior iliac spine with both hands and separates and squeezes outward and inward, and the presence of pain is considered positive, mostly for pelvic fractures. The clinical manifestations of pelvic fracture are pain, limitation of movement, hematuria, anuria and abdominal distension. The examination may reveal swelling of the pubic symphysis, inguinal ligament and perineum, subcutaneous bruising, abdominal distention and slowed bowel movement, positive pelvic compression and separation test, direct or indirect pressure pain in the pubic symphysis, impaired hip motion, pelvic deviation or significant displacement, and unequal lower limbs. Pelvic fractures generally do not pose a problem in clinical terms unless there is significant displacement, which affects function and stability, and importantly, their multiple injuries and complications can cause serious consequences such as shock or even death.
