When the tunnel that holds the tendons that move your fingers has a bump or is swollen it can’t slide smoothly. This can cause the finger or thumb to get stuck in the bent position. When it is unstuck it will pop back out like a trigger being released, but in severe cases cannot be straightened at all.
