Brief Answer:

Can be a trigger finger or muscle spasm.

Detailed Answer:

Hello,

The locking up of the finger joints can be due to trigger finger. Trigger finger happens when tendons in the finger or thumb become inflamed. Tendons are tough bands of tissue that connect muscles and bones.

Arthritis also leads to joint locking because as cartilage wears away, the ends of the bones that form a joint become rough.

Spasms, or cramps, are other causes of such locking of the fingers.

The most common causes of spasms are overused muscles (in the hands that might be due to writing or typing) and dehydration.

Other causes of muscle cramping include low levels of calcium and magnesium.

You need to get it examined by an orthopaedic and start with proper supplements or exercises as needed.

Hope I have answered your query.

Take care
