Sacral Fracture Evaluation

Immediate Assessment Priorities

The American College of Surgeons recommends documenting vital signs immediately, specifically looking for systolic blood pressure <90 mmHg, shock index >1, or requirement for bolus infusions/transfusions, to assess hemodynamic stability in patients with suspected sacral fracture 1, 2
The World Journal of Emergency Surgery suggests asking about any fluid resuscitation or blood products already administered, as transfusion requirement of 4-6 units within 24 hours indicates hemodynamic instability 2
Patients with suspected sacral fracture should be asked about symptoms of ongoing bleeding, such as lightheadedness, continued pain, or abdominal distension, to assess for hemodynamic instability 1

The Journal of the American College of Radiology recommends asking about lower back, pelvic, or sacral pain that worsens with weight bearing, as this is the classic presentation of sacral insufficiency fractures 3, 4
Patients with suspected sacral fracture should be asked about hip or groin pain, as sacral stress fractures can radiate to these areas 3, 6

The World Journal of Emergency Surgery suggests asking about blood in urine or at urethral meatus, as urethral injury occurs in 7-25% of pelvic ring fractures 1, 2
Patients with suspected sacral fracture should be asked about perineal or scrotal hematoma, and any difficulty voiding or catheter placement attempts, to assess for genitourinary trauma 1, 2

The Journal of the American College of Radiology recommends determining pregnancy status immediately in women of reproductive age, as pregnancy-related sacral fractures occur in the third trimester or postpartum period 5
Elderly or osteoporotic patients with suspected sacral fracture should be asked about previous fragility fractures, particularly vertebral compression fractures, and corticosteroid use, to assess for insufficiency fracture risk 3, 4, 6

The American College of Radiology suggests not relying solely on patient-reported symptoms to exclude sacral fracture, as clinical examination has only 81% sensitivity for spine fractures 2
The Journal of the American College of Radiology recommends not assuming isolated low back pain excludes sacral fracture, as presentation is often insidious, and not dismissing vague pelvic pain in elderly patients as "arthritis" without imaging 3, 4
