What Causes Finger-locking While Bending It?
Can be trigger finger.
Thanks for posting your query.
The locking of the finger in the flexed position can be due to a trigger finger. It happens due to stricture of the tendon and inflammation. Not likely to be related to a nerve issue or diabetes.
You need to consult an orthopedician for proper examination. Regular physiotherapy and local steroid injection can help.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
