American Board of Surgical Assistants (ABSA) Orthopedic Practice Test

Which type of fractures should be reduced before splinting without the aid of a physician?

1. Femur and/or tibia

2. Radius and/or ulna

3. Humerus and/or scapula

4. Tibia and/or fibula

The correct answer is: Radius and/or ulna

The correct answer focuses on the radius and ulna fractures, which are classified as forearm fractures. These types of fractures tend to have a higher risk of complications such as malunion if not properly aligned and stabilized in a timely manner. Reducing them before splinting can help to restore anatomical alignment, reduce pain, and prevent further injury. Forearm fractures are relatively common, particularly in children and in certain types of accidents where a person may try to catch themselves with an outstretched hand. By promptly reducing these fractures, one can also facilitate better blood circulation and prevent excessive swelling, which could complicate treatment later on. In contrast, other fractures, such as those involving the femur, humerus, or scapula, typically require more specialized care and intervention due to the complexity and potential for significant injury to surrounding structures. These fractures usually are associated with larger muscles and more substantial blood supply, which may necessitate physician intervention for both reduction and definitive treatment.
