Comparative Study
Can a day 4 bone scan accurately determine the presence or absence of scaphoid fracture?
To evaluate the accuracy of day 4 bone scans in predicting the presence or absence of fracture in patients with "clinical scaphoid fracture." ⋯ Day 4 bone scans are an accurate means of ruling out scaphoid fracture. However, because of a significant number of false-positive scans at day 4, they do not reliably confirm the diagnosis of scaphoid fracture. The bone scans also permitted identification of several other wrist fractures that had not been radiographically apparent.

Comparative Study
Paramedic injury severity perception can aid trauma triage.
To compare information contained in standard out-of-hospital trauma triage criteria and standard criteria plus advanced emergency medical technician (EMT) injury severity perception for determination of patient need for trauma center evaluation. ⋯ Standard out-of-hospital triage criteria benefit from inclusion of advanced EMT injury severity perception information.

To determine the spectrum of disorders in children younger than 6 years with upper-extremity injury or immobility and to identify clinical findings associated with specific disorders. ⋯ Most children with arm injury or immobility have bony or soft-tissue trauma, the majority being RHS. Clinical findings varied between diagnoses and may aid the clinician in deciding whether attempted reduction of RHS is indicated or whether radiographs are warranted first. Nontrauma diagnoses are unusual but should be considered, particularly in the child younger than 6 months old. Appropriate immobilization and follow-up are important for the management of children without a clear diagnosis at the initial evaluation.

To derive a highly sensitive decision rule for the selective use of radiography in acute knee injuries. ⋯ A practical, highly sensitive, and reliable decision rule for the use of radiography in acute knee injuries has been derived. Clinical application should await prospective validation of the rule.
