About Ultrasound-Guided Trigger Finger Release
Each finger tendon runs through a series of tunnels, called pulleys, that hold it close to the bone. In trigger finger, the first pulley at the base of the finger thickens, and the tendon catches on it, causing clicking, locking, or pain when bending and straightening the finger.
A steroid injection often helps as a first step. When triggering returns or persists, the pulley can be released. With ultrasound guidance, Dr. Gruner or Dr. Chen watches the tendon, pulley, and nearby nerves and arteries while releasing only the tight pulley through a needle-sized opening.
Because there is no open incision, recovery is usually quick, and most people can move the finger fully right after the procedure.
Where we use Trigger Finger Release
Watch: Trigger Finger Release explained
What happens during treatment
- 1.
Your physician examines the finger and uses ultrasound to see the thickened pulley and nearby structures.
- 2.
The palm at the base of the finger is numbed with local anesthetic.
- 3.
Under live ultrasound, a needle or small blade is used to release the tight pulley.
- 4.
You bend and straighten the finger to confirm it glides smoothly, and a small bandage is applied.
Who may be a good candidate
- People with trigger finger or trigger thumb that has not improved with a steroid injection.
- People whose triggering returns after an initial injection.
- People with a finger that locks or requires the other hand to straighten it.
- Patients who prefer an office procedure instead of open surgery.
Recovery
Most people use the hand for light tasks the same day. The palm may be sore for several days, and we suggest avoiding heavy gripping for a short period. Gentle finger motion is encouraged to keep the tendon gliding.
Risks and limits
Risks include soreness, bruising, bleeding, infection, incomplete release that leaves some catching, and rarely injury to a nearby nerve or tendon, which ultrasound guidance helps avoid. Some fingers, such as the thumb, are near delicate nerves and need careful planning. If your finger is stiff and cannot fully straighten, or has other hand conditions, open surgery may be a better choice, and we help coordinate referral.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Clinical evidence
Published studies our physicians draw on. Results in studies do not predict any one person's outcome.
Questions about Trigger Finger Release
- Should I try an injection first?
- For many people, a steroid injection is a reasonable first step and may be all that is needed. If triggering persists or returns, a release is often the next option.
- Will I need stitches?
- Usually not. The release is done through a needle-sized opening, so a small bandage is typically all that is needed.
- Can more than one finger be treated at once?
- Often, yes. More than one finger can usually be released in the same visit. Your physician will discuss what makes sense for your hand and daily activities.
