Unrecognised entrapment of a herniated bladder at the pubic symphysis following reduction and external fixation of an unstable pelvic fracture

Abstract

Bladder injury is frequently associated with complex pelvic fractures with men being the predominant population to sustain such injuries. Entrapment of the bladder through the site of pelvic fracture is a rare clinical entity. We report a case of an entrapped bladder post closed reduction and external fixation of an unstable anteroposterior compression type 3 (APC-3) fracture. This report highlights the diagnostic difficulty with identifying an entrapped bladder and the patient’s functional outcome after 1 year of follow-up.
