- Trigger Thumb Overuse Injury

- QUESTION: I have been having trouble with my right thumb. I went to the
- doctor and he says I have "trigger thumb". What exactly is that? He
- prescribed anti-inflammatory medication and said it might eventually mean
- surgery. Can you explain this diagnosis, please? Thank you, your column is
- most interesting and I read it every day.

- ANSWER: I am sure your doctor knows his medicine, but question his knowledge
- of fire arms. Ever try to pull a trigger with your thumb? I think he is
- applying another term "trigger finger" to a similar problem in your thumb. To
- flex your finger, the action that describes pulling a trigger, the flexor
- tendons are activated by muscles. These tendons pass through a sheath, a
- tunnel like structure that helps to lubricate and guide the tendons. When
- there is excessive use, the sheaths may become inflamed, causing pain and
- restricting motion. Treatment can consist of anti-inflammatory medication,
- injecting corticosteroids into the area, or eventually surgery. Surgery is
- necessary when there is scarring of the sheaths, the result of chronic
- inflammation, and opens the sheath to free the tendons and allow them to move
- freely. I must assume you have a flexor sheath problem in your thumb, and
- your physician is associating this with the more commonly described "trigger
- finger". Since the mechanisms and treatments are both the same, he is not
- that far off the target (hah!).
