EXERCISE 2: WHAT STRUCTURE IS THIS?
++
Exercise 2 Objective: Teach the user to recognize radiographic anatomy on the normal radiographs of the routine evaluation of the cervical spine hand and wrist.
++
Exercise type: 2: What Structure is This?
++
Instruction: User will look at the highlighted structure and identify it from a list of five possibilities.
++
View: Posteroanterior Hand
++
++
++
++
++
++
++
++
++
++
++
++
++
D. fif-5th digit proximal phalanx
++
++
E. articular surface of radius
+
++
Question Rationale: Sesamoids are a frequent reoccurrence at the metacarpophalangeal and interphalangeal joints of the thumb. The obliques view of the thumb on a posteroanterior view of the hand permits the sesamoids to be easily seen.

D. fif-5th digit proximal phalanx
++
++
E. articular surface of radius

D. fif-5th digit proximal phalanx
++
++
E. articular surface of radius
+
++
Question Rationale: The digits, or phalanges, are numbered the same as the metacarpals, 1st through 5th, starting from the thumb. Each finger has a proximal, a middle, and a distal phalanx.
