Straddle Fracture of the Pelvis

    • Fractures of both superior and both inferior pubic rami
    • With straddle fractures, there is a 40% chance of injury to the genitourinary tract, especially the posterior urethra and the urinary bladder in men
    • They are usually due to strong vertical shear injuries such as a fall from a height or a motorcycle accident
    • There is frequently vertical offset of the pelvis, which require stabilization
    • 95% of those with bladder injuries have gross hematuria
    • 1/3 of those with straddle fractures require laparotomy
    • CT has replaced conventional radiography in classifying pelvic fractures
