Pulmonary contusion and laceration are injuries to the lung tissue. It occurs on severe contusion, stretch, or laceration. The pancreas may be injured in abdominal trauma, for example by laceration or contusion. A laceration of the spleen may be associated with hematoma. The surface of the spleen is examined for evidence of laceration and fracture. Nerve injury most often occurs from ischaemia, compression, direct neurotoxicity, needle laceration, and inflammation. Haynesworth's cleats caused a laceration requiring thirty stitches. She sustained a broken jaw, a laceration under her eye, and a torn ear. Another "gaping laceration" measuring in length ran longitudinally from the umbilicus to the suprapubic region. Redding received ten stitches for a back laceration but escaped major injury. There were five serious injuries, including a deep laceration in flight attendant Doreen Welsh's leg. Surgical revascularization may be used in the setting of trauma (e.g., laceration of the artery). Brown's injury was diagnosed as a laceration to the kidney. His right eye was battered and had a superficial laceration. The laceration can be so extensive as to involve the rectum and anus.
