Trigger Finger Release CPT
Trigger Finger Release Indications
- Trigger finger of thumb that has failed conservative management
Trigger Finger Release Contraindications
Trigger Finger Release Alternatives
Trigger Finger Release Pre-op Planning
Trigger Finger Release Technique
- Prep and drape in standard sterile fashion.
- Local anesthetic injected into skin and flexor sheath.
- Longitudinal incision over A1 pully between the distal transverse palmar crease and the base of the finger flexion crease.
- Blunt dissection under loop magnification down to A1 pulley. A1 pulley is clearely visualized and NV bundles protected.
- A1 pulley is sharply released with #15 blade starting proximally just proximal to the base of the finger flexion crease which ensures the A2 pulley is preserved.
- Tendons are pulled from the sheath and inspected. Full triggerless motion is verified.
- Irrigation.
- Close skin
Trigger Thumb Release Technique
- Prep and drape in standard sterile fashion.
- Local anesthetic injected into skin and flexor sheath.
- Radially based V shaped flap incision centered over the thumb A1 pulley ath the MP crease. Ensure thumb MCP joint is in slight flexion during incision to decrease risk of injury to radial digital nerve.
- Blunt dissection under loop magnification down to A1 pulley. A1 pulley is clearely visualized and NV bundles protected.
- A1 pulley is sharply released with #15 blade starting proximally just proximal to the base of the finger flexion crease which ensures the A2 pulley is preserved.
- Tendons are pulled from the sheath and inspected. Full triggerless motion is verified.
- Irrigation.
- Close skin
Trigger Finger Release Complications
- incomplete cure
- digitial nerve injury
- A2 pulley release with bowstringing (Heithoff SJ, J Hand Surg 1988;13A:567)
- stiffness
- wound maceration
- vascular injury
- tendon laceration
Trigger Finger Release Follow-up care
- Post-op: light dressing with webril/ace-bangage. Start gentle ROM exercises
- 7-14 Days: Remove sutures. Continue home ROM exercises
- Light Duty for 3-6 weeks.
- 6 Weeks: Begin strengthening exercises. MMI 4-8 weeks.
Trigger Finger Release Outcomes
- Generally resolves completely after release.
