CT neck, chest, abdomen-pelvis (NCAP protocol)
The CT neck chest-abdomen-pelvis protocol aims to evaluate the neck, thoracic and abdominal structures using contrast in trauma imaging. The use of contrast facilitates the assessment of pathologies globally whilst minimizing dose by potentially disregarding a non-contrast scan.
Note: This art...

Green and O'Brien classification of thumb metacarpal fractures
The Green and O'Brien classification of thumb metacarpal fractures is a commonly used classification system when assessing thumb metacarpal fractures.
However, since most types of fractures coincide with well-known eponymous fractures, the system itself is not usually used properly, giving pref...
Article
Posterior shoulder dislocation
Posterior shoulder dislocations are far less common than anterior shoulder dislocations and can be difficult to identify if only AP projections are obtained. A high index of suspicion is helpful.
Epidemiology
Posterior shoulder dislocations account for only 2-4% of all shoulder dislocations (t...

Herbert classification of scaphoid fractures
The Herbert classification of scaphoid fractures, also known as the Herbert and Fisher classification, is one of the most frequently used classification systems when assessing scaphoid fractures.
The Herbert classification is proposed to provide a guide to the management of these fractures.
