Sex-related considerations

Acetabular and pelvic fractures occur in both men and women, but they are more common in men.

A low-energy fracture results in a fracture of the acetabulum without disrupting pelvic alignment (nondisplaced fracture), while a high-energy fracture may disrupt both the acetabulum and the overall alignment of the pelvic ring, and it is likely to lead to associated damage to the organs contained within the pelvis.

However, extension of force and subsequent tissue known to extend into the central, lower, and retroperitoneal portions of the pelvis will disrupt a different cadre of organs in men (posterior urethra, prostate, seminal vesicles) than occurs in women (posterior urethra, cervix, uterus, broad ligament, fallopian tubes and ovaries).

Of the 31,380 patients with pelvic fractures, 1,444 had genitourinary injury. Men more commonly sustained pelvic fractures with genitourinary injury than women (66.14% vs 33.86%). The incidence of urogenital, bladder, and urethral injuries for men and women was 5.34%, 3.41%, and 1.54%, respectively in men, and 3.62%, 3.37%, and 0.15%, respectively in women.
