Reliability of baseline scores for traumatically injured patients: advantages of using the patient-reported measurement information system (PROMIS) domains

Pelvic and acetabular fractures have a lower incidence (3% -5% and <1%, respectively) than other lower extremity fractures, but they have higher concomitance of other injuries, including injuries of the abdominopelvic organs, including the liver, pancreas, spleen, intestines and other genitourinary structures. For relatively low incidence, pelvic and acetabular fractures combined have more case-fatality between 8% -50% and poorer functional outcomes compared to other orthopedic traumatic injuries.
