# Pelvic Fracture

Pelvic fracture management hinges on early mechanical stabilization, rapid identification of competing bleeding sources, and pathway selection between laparotomy, preperitoneal packing, and angioembolization. Hemodynamic instability demands simultaneous damage-control resuscitation and definitive hemorrhage control at a trauma-capable center.

**Clinical question:** How should physicians stabilize, evaluate, and control hemorrhage in patients with suspected pelvic fracture?

## What matters in practice
- Apply a pelvic binder promptly when pelvic injury is suspected in a patient with tachycardia, hypotension, or a compatible high-energy mechanism; early splinting limits fracture motion and supports clot preservation. [10][20]
- In hemodynamically unstable pelvic fracture, use FAST to identify hemoperitoneum requiring exploratory laparotomy; manage suspected pelvic retroperitoneal bleeding with pelvic stabilization plus institution-specific packing and/or angiographic pathways. [2][12][23]
- Consider pelvic angioembolization for CT contrast extravasation regardless of hemodynamic status and for persistent hemorrhage after preperitoneal packing; repeat embolization is appropriate when bleeding continues after initial pelvic embolization. [23]
- For pelvic fracture urethral injury, initial urinary diversion should generally be percutaneous or open suprapubic tube placement rather than urethral instrumentation. [7]
- Transfer patients with pelvic fractures rapidly to a trauma center capable of urgent trauma surgery, orthopedic stabilization, interventional radiology, and critical care. [17][18]

## Stabilize suspected pelvic injury while determining whether the pelvis is the bleeding source

Treat hemorrhage and competing injuries in parallel.

Use an ABCDE trauma assessment and initiate resuscitation concurrently with pelvic assessment. Apply a pelvic binder early when the mechanism suggests pelvic disruption or when tachycardia or hypotension raises concern for pelvic hemorrhage. Early pelvic splinting reduces motion and helps protect clot formation. [8][10][20]

A pelvic fracture is a high-risk trauma marker rather than an isolated orthopedic diagnosis. Hemodynamic instability occurs in approximately 5% to 20% of pelvic fracture patients, with reported mortality of 18% to 40% in unstable presentations; prioritize hemorrhage control, associated abdominal injury assessment, and early trauma-center resources rather than waiting for definitive fracture characterization. [2][12]

Do not presume hypotension is pelvic in origin. Perform FAST during initial reassessment to identify hemoperitoneum. A positive FAST in an unstable patient directs exploratory laparotomy; when laparotomy is not indicated, proceed through the institutional pelvic hemorrhage pathway using mechanical stabilization and rapid access to pelvic packing and/or angiography. [2][12]
- Maintain the binder until mechanical stabilization or procedural positioning requires its removal; remove it before pelvic angiography or operative management in protocols using external fixation, and reassess after hemodynamic stabilization. [21]
- If the pelvis is adequately stabilized with a sheet or binder, immediate hardware fixation is not required solely for initial mechanical control. [23]
- Arrange rapid transport or transfer to the highest available trauma-center level when pelvic fracture is identified or strongly suspected, because urgent surgical, orthopedic, interventional radiology, and intensive-care resources may be required. [17][18]

*Initial branch points for suspected pelvic-fracture hemorrhage. [2][12][23]*

| Clinical branch | Immediate discriminator | Next action |
| --- | --- | --- |
| Suspected pelvic injury with tachycardia, hypotension, or high-risk mechanism | Clinical instability or mechanism compatible with pelvic disruption | Apply pelvic binder during ABCDE resuscitation and activate trauma resources. [8][10][20] |
| Unstable patient with hemoperitoneum | Positive FAST | Proceed to exploratory laparotomy; address pelvic hemorrhage with concurrent stabilization and damage-control measures as indicated. [2][12] |
| Pelvic fracture with no laparotomy indication | FAST does not direct laparotomy | Use local pelvic hemorrhage pathway: stabilization with preperitoneal packing and/or pelvic angiography with embolization. [2][23] |
| Persistent pelvic bleeding after embolization | Ongoing hemorrhage after prior pelvic angioembolization | Repeat pelvic angioembolization. [23] |

## Use CT and physiologic response to select hemorrhage control

Imaging should refine—not delay—the hemorrhage-control pathway.

In a patient sufficiently stabilized for CT, obtain contrast-enhanced CT to define pelvic-ring injury, associated abdominopelvic trauma, and vascular contrast extravasation. Pelvic contrast extravasation is an indication to consider angiography and embolization even if current hemodynamics are stable. [23]

Use ongoing transfusion requirement, recurrent hypotension, and failure to stabilize after binder-based reduction as evidence of continuing hemorrhage requiring escalation. Preperitoneal pelvic packing, external stabilization, angiography, and embolization are complementary modalities; the initial sequence varies by local availability and institutional protocol. [1][2][23]

At angiography, selective embolization of the bleeding vessel is preferred when feasible. In severe injury or diffuse pelvic bleeding, embolization of the entire internal iliac system may be necessary. Persistent bleeding after preperitoneal pelvic packing is also an indication to consider angiographic embolization. [23]
- Do not use absence of hemodynamic instability to dismiss CT arterial extravasation; consider angioembolization based on the CT finding. [23]
- Do not delay exploratory laparotomy for pelvic angiography when FAST identifies hemoperitoneum in an unstable pelvic-fracture patient. [12]
- Coordinate trauma surgery, orthopedic surgery, anesthesiology, and interventional radiology early; severe pelvic hemorrhage commonly requires more than one hemostatic modality. [2][3]

### Mechanical pattern and binder precautions

Pelvic ring disruption on radiography or CT identifies mechanical instability and supports urgent volume reduction with binder or external fixation. Complete disruption patterns include iliosacral fracture or fracture-dislocation, pubic symphysis diastasis, and sacral fracture. [21]

Avoid assuming that binder compression is harmless in every pattern. One trauma-center protocol withheld binder use in lateral-compression injuries because of concern for additional injury; therefore, maintain early stabilization while obtaining orthopedic trauma input once the fracture pattern is defined. [21]

*Hemorrhage-control tools in pelvic fracture. [1][2][3][23]*

| Modality | Best-supported role | Escalation or limitation |
| --- | --- | --- |
| Pelvic binder or sheet | Immediate reduction of pelvic volume and fracture motion during early resuscitation. [10][20][23] | Temporary measure; remove or modify for operative or angiographic access and reassess once stable. [21] |
| External fixation | Mechanical stabilization used with hemostatic procedures in unstable pelvic fracture. [3] | May replace ongoing binder use after placement; does not eliminate the need to address arterial or venous bleeding. [21] |
| Preperitoneal pelvic packing | Damage-control hemorrhage control in unstable pelvic fracture, particularly within surgical pathways or when laparotomy is required. [1][2][22] | Persistent hemorrhage after packing should prompt consideration of pelvic angioembolization. [23] |
| Angiography and embolization | Control of arterial pelvic hemorrhage; consider for CT contrast extravasation regardless of hemodynamics. [23] | Repeat if hemorrhage continues; diffuse injury may require internal iliac rather than selective embolization. [23] |

## Choose packing, laparotomy, and angioembolization by anatomy and response

The operative decision is driven by competing abdominal and pelvic bleeding priorities.

For unstable patients with a positive FAST, exploratory laparotomy takes priority because intraperitoneal hemorrhage requires direct abdominal control. When pelvic hemorrhage remains likely, add pelvic stabilization and consider preperitoneal packing during the damage-control operation rather than relying on angiography as the first procedural step. [2][12]

For an unstable patient without a laparotomy indication, rapidly select the locally available definitive pelvic hemorrhage pathway. Contemporary protocols use external stabilization with preperitoneal pelvic packing, pelvic angiography with embolization, or a staged combination; some centers add resuscitative endovascular balloon occlusion of the aorta in selected profoundly hemorrhagic patients. [1][2][3]

Do not frame packing and embolization as mutually exclusive. Packing addresses pelvic bleeding rapidly in operative damage-control pathways, whereas angioembolization identifies and treats arterial bleeding and remains appropriate for CT extravasation, persistent bleeding after packing, or recurrent hemorrhage after prior embolization. [1][2][23]
- If angiography is selected, seek selective embolization first when the bleeding vessel is identifiable. [23]
- Use nonselective internal iliac embolization when injury severity or diffuse bleeding prevents selective treatment. [23]
- After initial hemostasis, reassess for ongoing shock and pursue repeat pelvic angioembolization when bleeding persists after a prior embolization procedure. [23]

*Procedure selection by early hemorrhage scenario. [2][12][23]*

| Scenario | Preferred immediate procedural direction | Role of subsequent intervention |
| --- | --- | --- |
| Unstable pelvic fracture with positive FAST | Exploratory laparotomy for hemoperitoneum, with pelvic stabilization and packing as indicated. [2][12] | Perform angiography and embolization if pelvic hemorrhage persists after operative control. [2][23] |
| Pelvic fracture with CT contrast extravasation | Consider pelvic angiography and embolization irrespective of current hemodynamics. [23] | Repeat embolization for continued hemorrhage. [23] |
| Persistent bleeding after preperitoneal packing | Proceed to pelvic angiography and consider embolization. [23] | Use selective embolization when feasible; use internal iliac embolization for diffuse bleeding. [23] |
| Ongoing bleeding after pelvic embolization | Repeat pelvic angiography and embolization. [23] | Reassess for nonpelvic bleeding and adequacy of mechanical stabilization. [2][23] |

## Protect the urinary tract and plan trauma-center disposition

Associated visceral and genitourinary injury changes early procedural choices.

Suspect pelvic fracture urethral injury when the injury pattern and pelvic trauma raise concern for urethral disruption. For most patients with pelvic fracture urethral injury, establish initial urinary drainage with percutaneous or open suprapubic tube placement. [7]

Maintain a low threshold for multidisciplinary management because pelvic fractures are associated with abdominal, thoracic, vascular, neurologic, and genitourinary injury. In a preperitoneal packing cohort, associated chest injury and abdominopelvic injury were frequent, supporting deliberate reassessment for nonpelvic sources of shock rather than attribution of all instability to the pelvic ring. [21]

Patients with pelvic fracture require rapid specialized care because internal hemorrhage and associated injuries may require resources not available at every hospital. Field-triage guidance supports transport to a trauma center, where definitive hemorrhage control and coordinated orthopedic management can occur without delay. [17][18]
- Use suprapubic diversion as initial management for most confirmed or strongly suspected pelvic fracture urethral injuries. [7]
- Reassess shock after every intervention; continued hypotension may reflect unresolved pelvic bleeding, hemoperitoneum, thoracic injury, or another major hemorrhage source. [2][12][21]
- Defer definitive pelvic-ring fixation until hemorrhage control and physiologic stabilization have been achieved; initial binder or external stabilization provides temporary mechanical management. [3][23]

*Associated-injury actions that alter early pelvic-fracture management. [7][12][17][18]*

| Concern | Action | Reason for urgency |
| --- | --- | --- |
| Hemoperitoneum in an unstable patient | Perform FAST and proceed to exploratory laparotomy when FAST is positive. [12] | Intraperitoneal bleeding requires operative control and should not wait for pelvic angiography. [12] |
| Pelvic fracture urethral injury | Place a percutaneous or open suprapubic tube for initial urinary drainage in most patients. [7] | Avoid making urinary drainage contingent on immediate urethral reconstruction. [7] |
| Limited local trauma resources | Transfer rapidly to a trauma center. [17][18] | Pelvic fracture may require urgent trauma surgery, interventional radiology, orthopedic stabilization, and critical care. [17][18] |
