Purpose
[edit|edit source]
The purpose of the Thumb CMC Grind Test is to assess the integrity of the thumb CMC joint. Reproduction of the patient's pain and crepitus is a positive test for arthrosis and synovitis.
Technique
[edit|edit source]
The grind test is performed by gripping the patient's metacarpal bone of the thumb and moving it in a circle and loading it with gentle axial forces. A patient with thumb joint arthritis generally complains of a sudden sharp pain at the CMC joint.
