Finger stiffness and locking treatment: what to know

A catching finger may be assessed for Trigger Finger, while joint-line pain and swelling can point toward Hand Osteoarthritis or an inflammatory condition such as Rheumatoid Arthritis. A gradually bent finger with a palm cord may fit Dupuytren's Contracture. The clinician considers how long symptoms have lasted, whether the finger can be straightened, hand use, injury history and examination findings before recommending treatment.

Start with the plan provided for your specific cause: pacing aggravating tasks, prescribed pain relief, a night or activity splint, and controlled hand exercises may reduce irritation and maintain movement. A hand therapist can tailor exercises and teach safe tendon or joint mobility. An injection may be considered for selected tendon or joint problems. Persistent locking, a fixed contracture or failed non-operative care may lead to discussion of a procedure. Do not massage forcefully or repeatedly snap the finger open.

Get urgent help if locking follows an injury, the finger is visibly crooked, circulation or sensation changes, swelling rises quickly, or pain is severe. Fever, spreading redness, pus or a hot tender finger may signal infection and should be assessed promptly.

Ask which diagnosis is being treated, how long to try each option, how to use a splint, which exercises are safe, what side effects to watch for, and when a procedure should be reconsidered.
