What is the purpose of a pelvic binder in traumatic pelvic fracture, and when should it be reassessed?

• A. To decrease pelvic volume and control pelvic hemorrhage; reevaluate with imaging and plan for definitive stabilization; remove only under guidance
• B. To immobilize the leg
• C. To limit chest movement
• D. To secure the head

Answer: (A)

The purpose of a pelvic binder is to compress the pelvis to decrease pelvic volume and help tamponade bleeding from a pelvic fracture, providing temporary stabilization to support resuscitation while definitive care is arranged. This reduction in space helps limit venous bleeding and reduces pelvic motion that can worsen hemorrhage.

Reassessment should occur after initial stabilization and imaging. Once the patient has been resuscitated and pelvic imaging (X-ray or CT) has been reviewed, plan definitive stabilization such as external fixation for the pelvic ring or angiographic embolization for arterial bleeding. The binder is a temporary measure and should be removed only under guidance from the trauma team or surgical team, typically once definitive stabilization is in place or bleeding is controlled, with ongoing assessment for skin integrity and limb perfusion.
