The main conditions that cause this problem are repetition, rotating the forearm, or force. Unlike the tendons in the elbows, some are covered with a sheath. The tendons of the fingers, for example, are covered with a synovial sheath . The sheath is filled with a fluid that lubricates the tendon as it slides back and forth through the sheath. This fluid is called synovial fluid .
