An atypical presentation of heterotopic ossification following pelvic ring injury.

Disruption of the pelvic ring is associated with great morbidity and mortality. The high-energy blunt trauma that often leads to these injuries is also responsible for the head, chest, spine, extremity, and genitourinary trauma seen concurrently. Urethral and bladder injuries have been reported in up to 25% of patients with pelvic fractures and can lead to a plethora of urogenital problems. Heterotopic ossification of the penis, presenting as erectile dysfunction, has never been described as a complication of pelvic ring injury. We present the first case of this type of heterotopic ossification, in a 46-year-old male who sustained an anteroposterior compression type II injury with no evidence of genitourinary tract damage.
