Begin by understanding the anatomy of the wrist and the carpal bones. The carpal bones are a group of eight small bones that make up the wrist, connecting the hand to the forearm.
List the names of the carpal bones: Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, and Hamate.
Identify the names given in the problem: Scaphoid, Lunate, Talus, and Trapezium.
Compare the list of carpal bones with the names provided in the problem. Check which of these names is not part of the carpal bones.
Recognize that the Talus is not a carpal bone. It is actually a bone in the ankle, part of the tarsal bones, which are located in the foot.
