Final answer:
The statement "to exclude occult dislocation and concomitant injury, X-ray films must include the joints above and below the suspected fracture site is true.
So, the correct answer is A.True.
Step-by-step explanation:
To address the question of whether X-ray films must include the joints above and below the suspected fracture site to exclude occult dislocation and concomitant injury. When diagnosing bone fractures, it is crucial to assess not only the site of the direct injury but also the surrounding areas. This is because fractures can affect the stability and integrity of adjacent joints and bones.
For instance, in the case of an injury in the upper part of the ulna, which is just above the elbow joint, an X-ray might show that the bone has not only fractured but also requires stabilizing devices such as pins to align for proper healing.
Overexposure to X-rays is a concern, as it can increase the risk of cancer, but X-rays are pivotal for imaging due to their high penetrating energy compared to radio waves, making them suitable for identifying the extent and specifics of a fracture.
So, the correct answer is A.True.
