Case Reports
The applicability of a computer model for predicting head injury incurred during actual motor vehicle collisions.
Head injury is a significant cause of both morbidity and mortality. Motor vehicle collisions (MVCs) are the most common source of head injury in the United States. No studies have conclusively determined the applicability of computer models for accurate prediction of head injuries sustained in actual MVCs. This study sought to determine the applicability of such models for predicting head injuries sustained by MVC occupants. ⋯ Although computer modeling accurately simulates experimental crash tests, it may not be applicable for predicting head injury in actual MVCs. Many complicating factors surrounding actual MVCs make accurate computer modeling difficult. Future modeling efforts should consider variables such as age of the occupant and should account for a wider variety of crash scenarios.

Comparative Study
Comparison of poly-N-acetyl glucosamine with commercially available topical hemostats for achieving hemostasis in coagulopathic models of splenic hemorrhage.
The hemostatic quality of the poly-N-acetyl glucosamine (p-GlcNAc) patch was compared with a fibrin sealant, fibrin bandage, and cellulose patch. ⋯ Poly-N-acetyl glucosamine was effective at controlling bleeding in animals with experimentally induced or genetic coagulopathic disorders.

This study sought to define the role of transiliac sacral rods used in combination with an external fixator for the management of unstable pelvic fractures. ⋯ For type C pelvic fractures without significant iliac bone involvement, surgical management with posterior transiliac fixation using sacral rods and anterior external fixation yields good radiologic results. The functional results correlated primarily with avoidance of complications and not necessarily with the radiologic results.
