Anterior to the hand
May I touch your hand? (or point to the demonstrated area).
Please bring your thumb away from and toward your palm (or demonstrate and this is much easier when you demonstrate).
With the patient relaxed, gently place the fingers around the articulation of the trapezium with the metacarpal bone of the thumb. Either guide or demonstrate motions and observe as the patient moves through thumb carpometacarpal abduction and adduction.
Note that pure abduction is movement of the thumb away from the palm in a sagittal plane. Palmar abduction is movement of the thumb away from the palm and toward the little finger in a diagnonal plane. Radial abduction is movement of the thumb in a diagnonal plane away from the palm and away from the midline of the body.
