Locked fingers, known as trigger fingers, are more common in diabetics than in the general population. increase. This research diabetes care.
A trigger finger means that one or more fingers (often the ring finger or thumb) are in a bent position that is difficult to straighten. This is due to the thickening of the tendons that flex the fingers and their connective tissue sheaths, meaning that the fingers are fixed in a bent position toward the palm. It is often a painful condition that can be treated with cortisone injections, but sometimes surgery is required.
“Hand surgery clinics have long noted that patients with both type 1 and type 2 diabetes are more frequently affected by the trigger finger. Patients who have or develop diabetes,” said Mattias Rydberg, PhD student at Lund University and resident physician at Skåne University Hospital, and lead author of the study.
To study whether hyperglycemia (glycemic dysregulation) increases the risk of index finger stroke, researchers examined two registers: the regional Skane healthcare database containing all diagnoses and the Swedish National Diabetes Register. is. Although 1-1.5% of the population is affected by bandolier finger, the diagnosis occurs in 10-15% of diabetics, with the phenomenon most prevalent in her type 1 diabetic group.
Newly published research reinforces the pattern that blood sugar levels are an important factor in increased risk of trigger finger effects. Both men and women had an increased risk of being affected by the trigger finger.
Blood glucose is less than 48 when adjusted as measured by HbA1C, also called long-term blood glucose. The group of men with the lowest adjusted blood glucose levels (HbA1C > 64) had up to five times his risk. Properly regulated blood glucose levels (HbA1 < 48) were more affected than men.
“But we don’t know for sure if any group seeks health care more often than others. That could be a factor influencing the results,” Mattias Rydberg said. says.
The mechanism behind the increased risk is unknown, but one theory is that high blood sugar thickens both the flexor tendons and their connective tissue sheaths, making them more prone to locking. It has long been known that nerves are easily trapped in the hands.
“It is important to pay attention to the complications of diabetes and how they arise. increase.
“In addition to nerve compression and index finger, there may also be an association with thickening of connective tissue in the palm (Dupuytren’s contracture), impaired joint movement, and risk of arthritis at the base of the thumb. These complications The mechanism behind is probably different in diabetes.
Lars B. Darling, professor at Lund University and consultant in hand surgery at Skåne University Hospital, said:
The next step in the study is to find out how effective surgery is in diabetic patients with index finger involvement.
“From our experience in the clinic, the surgery goes well with few complications, but it does take some time for patients with type 1 and type 2 diabetes to regain full movement and function. Another interesting idea is to see if the index finger is a warning signal for type 2 diabetes.
“Although not everyone affected by the index finger has diabetes, it will be interesting to see if the updated register can be used to detect people who are in the risk zone for developing diabetes. I guess.

Purpose
Trigger finger (TF) is a hand disorder in which the finger locks in painful flexion. Diabetes is a known risk factor. However, it is unclear whether tight glycemic control effectively reduces his risk of TF.Our aim was to find out if HbA is high1c It was associated with an increased risk of TF in diabetic patients.
Research plan and method
The Swedish National Diabetes Registry (NDR) is cross-linked with the medical registry of the Skåne region in southern Sweden. In total, 9,682 of her patients with type 1 diabetes (T1D) and 85,755 with type 2 diabetes (T2D) aged 18 years or older were included from 2004 to 2019.1c and TF were calculated with sex-stratified multivariate logistic regression models with 95% CI, adjusting for age, duration of diabetes, BMI, and systolic blood pressure.
result
In total, 486 women and 271 men with T1D and 1,143 women and 1,009 men with T2D were diagnosed with TF. elevated HbA levels1c was associated with TF among T1D patients (female OR 1.26 [95% CI 1.1–1.4], P. = 0.001, male 1.4 [1.2–1.7], P. < 0.001) and T2D (female 1.14 [95% CI 1.2–1.2], P. < 0.001, men 1.12 [95% CI 1.0–1.2], P. = 0.003).
Conclusion
Hyperglycemia increases the risk of developing TF in patients with type 1 and type 2 diabetes. Optimal treatment of diabetes appears to be important for the prevention of diabetic hand complications such as TF.
