Just call us the Poster Trigger Thumb Family. My oldest daughter has just finished much of her recovery from her bilateral trigger thumb surgery (both thumbs). I also have fraternal twin daughters. 18 months ago, when they were born, my husband and I jokingly checked the thumbs of the twins to make sure that they were both straight. Because really, what were the odds that we'd have another child with the same problem? Hee hee. Ha ha. Ho ho.
Fast forward 18 months later. I'm clipping one of the twin's fingernails. I noticed a bit of a pop when I try to get my daughter to hold her right thumb still. She cries a bit. Oh no! I thought. Could this be trigger thumb? I checked her left thumb. It was locked in a bent position, going nowhere. I felt the bases of each thumb and sure enough, they both have the tell-tale knob on the tendon. What of the other twin? She's good; no little knob-ies. I like to think she takes after me.
You'd think that because I have already gone through this with one daughter, it wouldn't really be a big deal to me. And it really isn't. It's not life threatening. It's no emergency. But... I start thinking: Am I producing genetically inferior children? I've got four and 50% of them have trigger thumb! Oh well, they are really super cute, so I can get over the fact that we don't have designer children.
So, I call my eldest daughter's orthopedic surgeon. I just want to know if there is anything we can do, or if we just wait. Really, I know the answer. In many cases, trigger thumb can correct itself by age two. But since my daughter has a left thumb that is already locked and the right thumb that is well on its way to becoming locked (I'll be surprised if it doesn't), surgery will be the only option for her if I want her to be able to straighten her thumbs. And depending on the surgeon, they don't like to do it until 2-4 years of age. So, for now, we wait.
