Degloving injury to groin, scrotum and penis due to low-velocity handlebar injury.

Bicycles are a common cause of blunt abdominal trauma causing 5%-14% of injuries. However, impalement or shear injuries from low-velocity mechanism of injury are rare. We report a case of a 14-year-old boy presenting with an extensive left groin injury sustained while cycling one-handed along the pavement at walking pace. The laceration ran for 12-14 cm from the left groin across the pubis to the right and 10 cm inferiorly into the perineum. This inverted the left scrotum and partially degloved the penis. The corpus cavernosa and tunica vaginalis were exposed up to the level of the superficial inguinal ring. Literature on handlebar-impalement injuries is sparse and the majority of penile degloving injuries described in the literature result from alternative mechanisms. This unusual case demonstrates the potential forces involved, and potential damage resulting from handlebar injuries even at low velocity.
