[0] Pip & Dip Collateral Ligament Tests (These tests may be repeated in similar fashions to assess the collateral stability of the Distal Interphalangeal Joints or D.I.P. Joints.) [1] Position the patient so that the pronated forearm and hand are supported in a relaxed position on the table. [3] Grasp the medial and lateral aspect of the proximal phalanx 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 intermediate phalanx. While stabilizing the proximal phalanx with one hand, maintain the joint in 15 to 20 degrees of flexion. Use your other hand to radially distract the intermediate phalanx which stresses the ulnar collateral ligament of the proximal interphalangeal joint. While applying the stress, visualize and feel for abnormal opening of the joint as compared to the uninvolved joint of the other hand. 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 indicates a sprain of the ulnar collateral ligament. [2]
