When a peripheral tear of the TFCC is encountered there is a positive trampoline test noted. Probing the central portion of the TFCC demonstrates significant laxity because of the peripheral detachment that occurs with Palmer 1B tear. Significant synovitis is almost always encountered along the ulnar...
