[0] Mallet Finger Test [1] Position the patient with the forearm in pronation and the hand relaxed on the table surface. [3] Isolate the tendon by holding the involved finger at the middle phalanx. Begin with the D.I.P. joint relaxed in flexion. Instruct the patient to extend the D.I.P. joint. Inability to extend the D.I.P. joint is indicative of extensor tendon avulsion at its attachment on the base of the distal phalanx. [2] 
Assesses extensor tendon integrity at the DIP joint.
