In briefA male skateboarder experienced chest wall pain and splinting after striking a curb with the right side of his torso. X-rays revealed a nondisplaced fracture of the right ninth rib. Two days later, however, the patient returned with hematuria, and CT showed a renal laceration. This case illustrates that minor symptoms can accompany serious injury after abdominal trauma. Also, as skateboarding gains popularity, such injuries may become more frequent.
