Question

In the PA oblique projection of the wrist, which of the carpals will be demonstrated distal and lateral to the lunate? 1. Scaphoid 2. Trapezium 3. Trapezoid 4. Triquetrum A) 1 and 2 B) 2 and 3 C) 1, 3, and 4 D) 1, 2, and 3

Answer 1

In a PA oblique projection of the wrist, the Scaphoid and Trapezium bones are located distal and lateral to the Lunate. Understanding the carpal bone arrangement is crucial to correctly diagnosing and treating wrist injuries.

Step-by-step explanation:

In the PA oblique projection of the wrist, the carpals that can be demonstrated distal and lateral to the lunate are the Scaphoid and Trapezium. The Scaphoid is found proximal to the lunate while the trapezium is found distal to it but still in the lateral position.

The carpal bones comprised of eight small bones form the wrist's base. Two rows are formed, with a proximal row and a distal row, each containing four carpal bones. It is important to note the location of these bones because errors in identifying them correctly can lead to misdiagnosis and improper treatment of wrist injuries.
