What should you know about pinky finger stiffness and locking?

A tendon can catch as it passes through a tight or irritated passage, producing the clicking or stuck feeling associated with Trigger Finger. Joint swelling or wear can also reduce smooth movement; Hand Osteoarthritis may cause painful stiffness. Rheumatoid Arthritis can inflame several joints, while Dupuytren's Contracture can gradually limit straightening because tissue in the palm tightens.

Notice whether the finger locks while bending or straightening, whether it releases by itself or needs the other hand, and whether the palm is tender. These details help distinguish a movement problem from a fixed bend or an injury.

Reduce repeated gripping, squeezing, and activities that provoke catching. Keep the hand warm, move the finger gently without forcing it through a lock, and avoid pulling it sharply into position. A clinician may suggest a temporary splint, targeted hand exercises, or another treatment after examining the tendon and joints. Do not inject, puncture, or alter the finger yourself.

Book an assessment when locking recurs, interferes with dressing or work, or leaves the finger increasingly bent. Get urgent help if the finger is suddenly deformed after an injury, cannot be moved, loses feeling, or becomes cold, pale, or blue. Rapid swelling, severe pain, or an open wound also needs prompt attention.

Ask whether the catching is coming from the tendon or a joint, whether a splint could help, and what exercises are safe. Ask what findings would lead to an injection or surgery, and how to manage symptoms if more than one finger becomes stiff.
