[1] Position the patient so that the pronated forearm and hand are supported in a relaxed position on the table surface. To enhance examination and visualization, ask the patient to slightly flex the uninvolved fingers further into flexion than the involved finger. [3] This same test may then be reversed by distracting the proximal phalanx ulnarly to stress the radial collateral ligament. Again maintain the joint in 30 degrees of flexion while stabilizing the metacarpals with one hand. Use your other hand to ulnarly distract the proximal phalanx which stresses the radial collateral ligament of the metacarpophalangeal joint. While applying the stress, visualize and feel for abnormal opening of the joint as compared to the uninvolved contralateral joint. Again, there should be a slight opening with a firm end point. A sprain of the radial collateral ligament is indicated by the absence of a firm end point accompanied by associated sensations of pain or instability. [2] 
Assesses the radial collateral ligaments of the metacarpophalangeal joints.
