Pelvic Ring Fractures
Stability, binders, and when to fix.

At a glance
Pelvic ring injury is a resuscitation problem before it is an implant problem. Unstable patterns can bleed into a huge retroperitoneal space. Mechanical stability and hemorrhage control come first; definitive fixation follows when the patient and soft tissues allow.
Read the AP pelvis for ring disruption, then decide binder, binder + OR, angio, or packing based on the bleeding pathway — not on habit.
Classification
- Young-Burgess mechanism language: APC, LC, VS (useful for associated injury patterns)
- Tile / AO stability language: stable vs rotationally unstable vs vertically unstable
- On call, say whether the ring is stable enough for mobilization and whether vertical instability is present
Decision-making
Hemodynamically unstable + pelvic ring injury → binder early, massive transfusion thinking, and a clear bleeding algorithm with trauma surgery. Do not remove a working binder for pretty films.
Stable LC patterns may be non-op. APC III / VS patterns and displaced symphyseal / SI injuries often need operative stabilization for bleeding control, pain, and mobilization.
Treatment
- Pelvic binder for unstable open-book physiology
- Temporary external fixation / C-clamp in selected patterns
- Angiographic embolization or preperitoneal packing per institutional protocol
- Definitive anterior and/or posterior fixation once resuscitated
- Open pelvic fractures need antibiotics and soft-tissue / perineal care urgency
High-yield / exam
- Binder early in unstable pelvic bleeding
- Vertical instability changes the fixation plan
- Open pelvis = soft-tissue and infection emergency
- Associated urethral / bladder injury screening
