A case of ipsilateral fracture-dislocation of the hip, knee, and ankle is presented. The patient had no neurovascular compromise or postoperative complications. A review of the literature produced no previous reports of this combination of injuries.

Computed tomography is used with increasing frequency to evaluate blunt chest trauma. Since traumatic aortic rupture (TAR) is a rapidly lethal condition, unnecessary CT scanning may not be justified. To determine the accuracy of chest CT scanning for TAR, we reviewed 17 patients who underwent both chest CT scanning and aortography. ⋯ The specificity was 23% and the sensitivity was 83% compared with aortography. The overall accuracy for CT scanning was 53%. From these data we conclude that in the presence of an unstable patient or where there is a strong clinical suspicion of TAR the patient should proceed directly to aortography.

Comparative Study
Combined hemorrhagic shock and head injury: effects of hypertonic saline (7.5%) resuscitation.
Hypertonic saline resuscitation was compared to isotonic fluid resuscitation in a large animal model combining hemorrhagic shock with head injury. Sheep were subjected to a freeze injury of one cerebral hemisphere as well as 2 hours of hypotension at a mean arterial pressure (MAP) of 40 mm Hg. Resuscitation was then carried out (MAP = 80 mm Hg) for 1 hour with either lactated Ringer's (LR, n = 6) or 7.5% hypertonic saline (HS, n = 6). ⋯ No differences were detected in the injured hemispheres. We conclude that hypertonic saline abolishes increases in ICP seen during resuscitation in a model combining hemorrhagic shock with brain injury by dehydrating areas where the blood-brain barrier is still intact. Hypertonic saline may prove useful in the early management of multiple trauma patients.

Review Case Reports
Isolated hyoid bone fracture: a case report and review of the literature.
Isolated hyoid bone fractures secondary to trauma other than strangulation are rare and have few, if any, complications. We report a case of an isolated hyoid bone fracture that resulted in sudden and severe upper airway compromise. Diagnosis of these fractures is difficult and usually can be made only with a strong degree of suspicion. Patients who suffer neck injuries in whom a hyoid fracture is diagnosed or strongly suspected should be observed for 48 to 72 hours, considered for endoscopy, and treated as warranted.

Based on the 242 consecutive surviving head injury cases and 132 general trauma cases, this study examined the contribution of brain and non-brain injuries to cognitive and psychosocial outcome 1 month postinjury. The study also examined the relationships among various head injury severity indices. ⋯ Psychosocial outcome related to both brain and non-brain injuries independently. When evaluating trauma outcome, it is important to consider the contributions of both brain and other system injuries.
