unstable pelvis
Pelvic fracture pattern that disrupts the pelvic ring and may cause life-threatening hemorrhage requiring immediate stabilization.
Full Definition
A classification of pelvic fractures involving disruption of both anterior and posterior elements of the pelvic ring, resulting in mechanical instability and potential for massive hemorrhage. These fractures typically result from high-energy trauma and may involve injury to major vessels, nerves, and pelvic organs. Emergency management focuses on immediate stabilization using pelvic binders or external fixation, hemorrhage control, and recognition that surgical intervention may be required for both fracture stabilization and management of associated injuries.
Usage
