Role of pelvic binders in unstable pelvic fracture.

• A. To reduce pelvic volume and limit hemorrhage.
• B. To immobilize the entire patient.
• C. To immobilize the arms.
• D. To treat infection.

Answer: (A)

Pelvic binders work by wrapping around the pelvis to compress the pelvic ring, which reduces pelvic volume and tamponades bleeding from pelvic vessels and bone surfaces. This stabilization helps control hemorrhage and improves the patient’s hemodynamics while definitive measures (like external fixation or angiographic embolization) are arranged. It’s a temporary measure focused on hemorrhage control and stabilization, not on immobilizing the entire patient, immobilizing the arms, or treating infection. Apply snugly at the level of the greater trochanters, monitor distal sensation and circulation, and reassess as definitive care proceeds.
