What it is
Trigger finger release involves dividing the A1 pulley to allow for smooth tendon glide. It is a short procedure performed under local anaesthetic for persistent locking or painful catching. The goal is reliable finger motion without snap or block.
Rehabilitation restores motion, reduces swelling, and builds grip endurance.
What happens when it occurs
A small incision or needle technique is used to release the pulley. Early motion prevents stiffness; scar care reduces tenderness. Strength and dexterity progress as comfort allows.
Common causes and indications
- Persistent painful catching despite splinting or injection
- Recurrent locking that interferes with work or sleep
- Coexisting conditions such as diabetes
Who is most affected
Adults in midlife and older; more common in women. The thumb and ring finger are frequent sites.
Typical symptoms before surgery
- Painful snap when bending or straightening
- Locking that sometimes needs the other hand to release
- Tender nodule at the base of the finger
When to seek care
When locking persists or returns after conservative care.
How we diagnose
History and examination of the A1 pulley with observation of catching. Ultrasound is used selectively.
Management
- Wound care and early finger motion
- Scar management and desensitisation
- Grip and pinch endurance progression
- Task practice and graded return to work
Rehabilitation milestones
Phase 1 days 0–7: motion and swelling control.
Phase 2 weeks 1–3: scar care, light strengthening, dexterity drills.
Phase 3 weeks 3–6: return to complete work and hobbies.
Readiness to progress
- Wound healed and smooth motion without triggering
- Grip endurance improving toward targets
- Tasks completed without next‑day soreness
Long-term care
- Vary gripping tasks and tool sizes
- Maintain forearm endurance
- Address coexisting tendon or nerve issues
Australia snapshot
- Standard day procedure with rapid return to light tasks
- Accessible in public and private settings
- High satisfaction when rehabilitation is followed
Latest insights
Early motion and scar care prevent stiffness and tenderness.
