NOTE: All hand casts are applied absent of pronation, supination, radial, or ulnar deviation unless
directed by physician.

NOTE: Placing the thumb and forefinger in opposition to one another assists the patient in maintaining
wrist in neutral position. This is commonly referred to as the can of coke position.
b. Place the stationary arm of the goniometer vertically, bisecting the ulnar.
c. Place the moving arm of the goniometer vertically, bisecting the lateral side of the 5th
