BACKGROUND Bone contusions are often identified at magnetic resonance imaging (MRI) in the acutely injured knee. Contusions of both surfaces of the joint are known as kissing contusions. OBJECTIVE To determine the frequency, type, and distribution of kissing contusions occurring in association with injuries of the knee joint. METHODS 255 MRI examinations in athletes with acutely injured kne...

Ninety-eight brain contusions in 17 patients served as a data base for a comparative study of MR and CT for defining brain contusions. MR was the more sensitive technique, detecting 98% of the brain contusions compared with only 56% by CT. CT was slightly better for showing hemorrhagic components, documenting 77% of hemorrhages compared with 71% for MR. The appearance of the contusions on MR wa...

What are the most common causes of spinal cord contusion? Most spinal cord contusion injuries are the result of highimpact motor vehicle accidents. However, athletes can sustain this injury as a result of contact while playing. Fortunately, the number of serious incidents involving spinal cord injury is low. That being said, more orthopedists are beginning to function as the team physician duri...

BackgroundPulmonary contusions are common injuries. Computed tomography reveals vast contused lung volume spectrum, yet pulmonary defined dichotomously (unilateral vs bilateral). We assessed whether there is stepwise increased risk of complications among patients without, with unilateral, and bilateral contusion.MethodsWe identified adults admitted rib fractures using the largest US inpatient d...
