Diabetes & Trigger Finger – Prevention and Treatment

Trigger finger is actually incredibly common in people living with diabetes. While it affects the non-diabetic population, too, the most effective treatment and the path to relief for those with diabetes has proven to be very different.

In this article, we’ll look at what trigger finger is, what causes it and increases your risk of developing it, and what the most effective treatment options are for people living with diabetes.

What is trigger finger?

This condition is an issue within your musculoskeletal system that affects the tendons and ligaments in your fingers, particularly the “tendon sheaths.”

Just as it sounds, trigger finger is characterized by your finger forming into a bent position as if you were pulling the trigger on a gun. It can develop in any of the tendons of any of your fingers.

The first signs and symptoms will include swelling, stiffness, and pain. You may eventually develop a bit of a “bump” around the joint(s) of that finger or where it connects to the palm of your hand.

What’s going on physically within that finger and it’s tissues is severe inflammation in the sheath of the tendon that acts much like a restraint. Instead of gliding back and forth, it becomes stuck, further inflamed and irritated, and eventually locked in that bent position.

 

What causes trigger finger?

The exact cause of trigger finger is still unclear. However, there are certain things that increase your risk of developing the condition.

Research has determined that most cases of trigger finger developing between the ages of 40 to 60 years old. Women are more likely to develop trigger finger than men.

You have an increased risk of developing trigger finger if you have…

  • a history of diabetes
  • a history of elevated blood glucose levels
  • a history of carpal tunnel syndrome
  • a history of rheumatoid arthritis
  • a previous incidence of trigger finger in another digit

In fact, patients with type 1 diabetes or carpal tunnel syndrome are twice as likely to develop trigger finger compared to the general population, according to a 2012 study from Massachusetts General Hospital in Boston, MA.

The 2012 study from Massachusetts General hospital also reported that 22 percent of patients who had been treated for trigger finger developed the condition in another digit within 2 years.

A 2010 study from Kakegawa City General Hospital, Kakegawa, Japan, concluded an even higher risk of trigger finger in the diabetes population, stating this population is 4 times more likely to develop trigger finger compared to the non-diabetic population.

This Japanese study also found that the risk of developing trigger finger was significantly higher in insulin-dependent patients.

Approximately 4 percent of patients with diabetes in the study had two or more affected fingers. And in patients with more than 3 affected fingers, there was a clear connection to their blood sugar levels and overall diabetes wellbeing.

 

Treatment options for trigger finger

Treating trigger finger in people with diabetes should be approached differently than in a non-diabetic patient.

The most common treatment options for all cases of trigger finger include:

  • Rest of the affected digit(s)
  • Physical therapy. Gentle stretching exercises can help improve flexibility and range of motion
  • Splinting the finger along with over-the-counter anti-inflammatory drugs (NSAIDs)
  • Multiple or ongoing injections of corticosteroids and/or lidocaine
  • Surgically releasing the locked tendon

While 66 percent of trigger finger cases in non-diabetic patients can be treated effectively with steroid injections, that’s not the case for the diabetes population.

Using steroids in people with diabetes can be tricky, as steroids lead to nearly immediate and prolonged increased blood sugar levels that are very difficult to combat with an increase in insulin doses.

 

Some patients may find they need as much as 50 percent more insulin in their system to counter the side-effects of steroids on their blood sugar levels. Since managing blood sugar levels as tightly as possible is a crucial part of recovering and managing trigger finger in people with diabetes, this creates a nearly impossible environment that will not promote healing.

Research has also found that steroid injections for trigger finger in patients with diabetes simply isn’t effective in treating the condition, according to a study published in The Journal of Hand Surgery. While approximately 28 percent of the non-diabetic population requires surgery to properly correct trigger finger, 56 percent of patients with diabetes will require surgery.

When it comes to the cost of treating trigger finger in people with diabetes, a 2016 study from Brigham and Women’s Hospital in Boston, MA took into account a 35 percent failure rate of treating with corticosteroid injections.

While one injection into a jointed area like the finger can cost as much as $300 per injection, it’s important to remember that a patient with diabetes would likely need multiple injections.

Considering the failure rate of steroid injections, the cost of surgical release for the tendon is generally $600 to $700. The failure rate of surgically treating trigger finger is nearly non-existent, and thus more cost-effective for the average patient with diabetes.

 

Preventing trigger finger

Very simply, the number one thing you can do to prevent trigger finger as a person with diabetes is to manage your blood sugars as healthfully as possible.

If that means talking to your doctor about additional medications or asking for help with persistently high blood sugars, don’t wait. Trigger finger can be a painful and frustrating condition.

While healthy blood sugar management alone does not guarantee you won’t develop trigger finger, it is the most important thing we can do as people with diabetes to greatly reduce our risk of developing the condition.

If you think you are developing trigger finger, avoiding repeated gripping motions and resting your fingers as much as possible can also help prevent the condition – but even total rest is not a guarantee that you won’t develop trigger finger.

    Trigger Finger, oh boy/girl!!!! I am a chiropractor in Evanston, IL and I use my hands all day. I am also an avid homebrewer, chef, cross stitcher, crossword solver and puzzle piece placer. All things that require me to use my hands. I have been diabetic for the past 26 years, and on some form of insulin the entire time. With the recent COVID keeping people home, I have had a lot of time on my hands, so I found a box of half started cross stitch patterns I wanted to finish. Now after 5 projects in 2 months, my index and thumb on my right hand are giving me trouble. These will be fingers 4 and 5 have experienced trigger finger. I found that a good stretching routine and scraping along the muscle and tendon, even with all the pain, helps to break up the adhesions in the sheath. You will have a lot of swelling after, but it goes away with movement and stretching.

    T1 43 years, insulin pumper. I’ve had trigger finger twice. I wholeheartedly agree with Joyce that you need activity to combat this! The first time, it lasted 1 1/2 yrs on my right hand ring finger. What cured it was intense note-taking for a week-long class. Part way through I noticed my finger was functioning normally again!

    I have also had frozen shoulder a few times. We have found the treatment for that is twice daily massages with arnica in cream or gel form. Arnica is an herbal remedy. The same will help trigger finger. This I’ve used for the 2nd experience, which did not last as long!

    Inactivity will NOT help, but only make things worse!

    I have had Type I for forty years and have been working on a computer since they were invented and type writers before that. I started developing triggers fingers a couple of years ago and have had nine out of 10 of my fingers surgically repaired along with bilateral carpal tunnel even though my A1cs have been bang on.

      That is frustrating. But also shows that no matter how well we manage our diabetes complications can still arise. Hope the surgery has helped you

      I had no idea it would eventually effect every digit. I had surgery on 1 finger in December. Now I have 3 more in splints. Very upsetting.

    I have had carpal tunnel surgery on both my hands, plus trigger release on both my thumbs 5 years ago. The procedure was entirely successful and I have no symptoms in my thumbs and no recurrence of the carpal tunnel. However, I now have trigger symptoms in my remaining 8 digits…I have found that resting definitely makes them worse. The best treatment is using them (in the gym doing strength training using weights) and just general activity diminishes the symptoms. Resting means that everything just gets tighter – this makes sense because that’s what bodies are designed to do! It’s a little depressing when you grip something and one of your fingers locks and it hurts but moving on and not dwelling on it is the best thing I’ve found to do.
    Oh and details about me – diabetic for nearly 50 years. Last 10 years my blood sugars have been near normal (best since I was pregnant in my 30s) so I’m obviously reaping a mis-spent youth when the internet wasn’t available to help!
