[0] Gamekeeper's Thumb Test [1] Position the patient with the forearm in neutral and the hand supported in a relaxed position on the table surface. [3] Grasp the medial and lateral aspect of the first metacarpal with your thumb and index finger. Use the thumb and index finger of your other hand to grip the medial and lateral aspect of the proximal phalanx, maintaining the joint in extension. Apply ulnar stress to the joint by abducting the proximal phalanx. While applying the stress, visualize and feel for abnormal opening of the joint as compared to the contralateral thumb. Normally, there should be a slight opening with a firm end point. The absence of a firm end point accompanied by associated sensations of pain or instability indicate a sprain of the ulnar collateral ligament. [2] 
Assesses ulnar collateral ligament stability at the thumb's metacarpophalangeal joint.
