Observational Study
Musculoskeletal Ultrasonography to Diagnose Dislocated Shoulders: A Prospective Cohort.
Shoulder dislocations are a common injury leading to emergency department presentations. Point-of-care ultrasonography has the potential to reduce radiation and time to diagnosis. We determine the accuracy of a novel point-of-care ultrasonographic technique to diagnose dislocated shoulders. We also investigate its accuracy to detect fractures, time to image acquisition, the optimal cutoff for the glenohumeral distance, and compare the time to diagnose dislocations from triage between point-of-care ultrasonography and radiography. ⋯ A posterior approach point-of-care ultrasonographic study is a quick and accurate tool to diagnose dislocated shoulders. Ultrasonography was also able to accurately identify humeral fractures and significantly reduce the time to diagnosis from triage compared with standard radiography.

In the current era of frequent chest computed tomography (CT) for adult blunt trauma evaluation, many minor injuries are diagnosed, potentially rendering traditional teachings obsolete. We seek to update teachings in regard to thoracic spine fracture by determining how often such fractures are observed on CT only (ie, not visualized on preceding trauma chest radiograph), the admission rate, mortality, and hospital length of stay of thoracic spine fracture patients, and how often thoracic spine fractures are clinically significant. ⋯ Thoracic spine fracture is uncommon. Most thoracic spine fractures are associated with other thoracic injuries, and mortality is more closely related to these other injuries than to the thoracic spine fracture itself. More than half of thoracic spine fractures are clinically insignificant; surgical intervention is uncommon and neurologic injury is rare.
