Middle Finger Stiff and Locking

Catching near the base of the finger, especially when making a fist, is a typical pattern of [Trigger Finger](/conditions/trigger-finger/). Painful joint swelling and reduced motion can occur with [Hand Osteoarthritis](/conditions/hand-osteoarthritis/), while inflammatory stiffness may involve several joints in [Rheumatoid Arthritis](/conditions/rheumatoid-arthritis/). A firm cord or gradual pull toward the palm can fit [Dupuytren's Contracture](/conditions/dupuytren-contracture/). These patterns overlap, so the timing of locking and the location of tenderness are useful details.

Limit repeated gripping, vibrating tools, and forceful pinching while the finger is irritable. Use gentle opening and closing movements without pushing through a catch. Warmth may help before movement, but do not force the finger past a lock or try to release it with a sudden pull. A hand clinician can consider activity changes, exercises, splinting, medication options, or other treatment based on the examination.

Seek an appointment if locking is recurrent, painful, worsening, or interfering with work, dressing, or sleep. Get prompt care after an injury when the finger is deformed, severely swollen, numb, pale, or impossible to move. Fever, spreading redness, or rapidly increasing pain also needs urgent assessment.

Ask whether the catch is coming from the tendon or a joint, whether a night splint could help, and which exercises are safe. Ask how to protect the finger during work and what change would mean that a locked position needs faster review.
