Understanding Trigger Finger
The snap you feel when straightening your finger is the flexor tendon releasing past a thickened pulley. The cause is the pulley, not the tendon. That is what treatment needs to address.
The flexor tendons of the fingers run through a series of fibrous tunnels (pulleys) that keep the tendon close to the bone during movement. In trigger finger, the A1 pulley at the base of the finger thickens and narrows. The flexor tendon catches and snaps as it passes through the constriction.
Mild trigger finger produces catching and occasional snapping. Moderate trigger finger requires the other hand to straighten the affected finger. Severe or fixed trigger finger cannot be straightened at all. The appropriate treatment depends heavily on which stage you are in.
At Joint Freedom, we use ultrasound to assess pulley thickness and tendon sheath involvement, and treat mild to moderate presentations with laser and PRP before considering surgical referral.

Who Gets Trigger Finger?
Trigger finger is more common in middle-aged women, patients with diabetes, and anyone with repetitive gripping in their daily activity. The ring and middle fingers of the dominant hand are most commonly affected.
Common Risk Factors
- Repetitive gripping in occupation or sport
- Diabetes (significantly elevated risk)
- Rheumatoid arthritis
- Hypothyroidism
- Female sex (more common than male)
- Age 40 to 60 (peak incidence)
Symptoms and When to Seek Treatment
The locking and snapping pattern is distinctive. Severity determines which treatment is appropriate.
Common Symptoms
- A catching, locking, or clicking sensation when bending or straightening a finger
- Pain at the base of the affected finger, particularly with gripping
- A tender nodule at the base of the finger on the palm side
- Morning stiffness that improves with movement
- A finger that locks in a bent position and must be straightened with the other hand
See a Specialist If...
- Finger locks and cannot be straightened without manual assistance
- Symptoms are present in multiple fingers
- Cortisone shots have provided only temporary relief
- Underlying conditions such as diabetes or rheumatoid arthritis are present
Common Causes of Trigger Finger
Repetitive gripping, systemic conditions, and often no clear single cause.
MOST COMMON
Repetitive Gripping
Prolonged or repetitive gripping activities thicken the A1 pulley, the fibrous band that guides the flexor tendon in the finger. The tendon catches on the thickened pulley during movement.
SYSTEMIC
Associated Medical Conditions
Diabetes, rheumatoid arthritis, and hypothyroidism all increase the risk of trigger finger. In diabetic patients, multiple fingers are often affected and the condition is more recalcitrant to conservative treatment.
IDIOPATHIC
Spontaneous Onset
Many trigger finger cases develop without a clear identifiable cause. Middle-aged women and dominant-hand ring and middle fingers are the most commonly affected.
How We Diagnose Trigger Finger
Clinical exam grades severity. Ultrasound guides treatment decisions and injection placement.
Clinical Exam
We palpate the A1 pulley for tenderness and nodularity, assess the degree of triggering (mild catching vs. locking), and screen for underlying conditions that affect the approach.
Ultrasound Assessment
Ultrasound visualizes the A1 pulley thickness, the tendon nodule, and the degree of tendon sheath involvement. Guides injection placement for cortisone or PRP.
Treatment Plan
Mild to moderate triggering: laser series plus splinting. More significant triggering or recurrence after cortisone: PRP into the tendon sheath. Fixed locking: refer for surgical evaluation.

What You Can Do at Home
Night splinting and activity modification are the most effective home measures alongside clinical treatment.
What Helps
- Splinting the affected finger in extension, particularly at night
- Warm soaks before activity to reduce morning stiffness
- Avoiding sustained, forceful gripping during treatment
- Gentle active range-of-motion exercises to maintain tendon gliding
- Management of underlying conditions (diabetes, thyroid) with your primary care provider
What to Avoid
- Force a locked finger straight without clinical guidance
- Continue repetitive gripping activities without modification during treatment
- Accept that repeated cortisone shots are the only alternative to surgery
- Ignore trigger finger in multiple fingers without assessment
How We Treat Trigger Finger
Laser for mild to moderate cases and PRP as an alternative to repeated cortisone.
LIGHTFORCE XLi
Laser Therapy
Class IV deep-tissue laser reduces tendon sheath inflammation and can reduce the thickening of the A1 pulley that causes catching. Effective for mild to moderate trigger finger, often eliminating the need for injection.
REGENERATIVE MEDICINE
PRP Therapy
Platelet-rich plasma injected into the flexor tendon sheath supports recovery in cases with recurrent triggering after cortisone. An alternative to repeated cortisone for patients who have reached the safe injection limit.
Which Treatment Is Right for Your Finger?
Severity grade determines the appropriate starting point.
01
MILD TRIGGERING (CATCHING WITHOUT LOCKING)
Laser and Splinting
A laser series combined with night splinting and activity modification. Many mild cases resolve within 4 to 8 weeks without injection.
02
MODERATE TRIGGERING OR CORTISONE RECURRENCE
PRP into the Tendon Sheath
PRP delivered into the flexor tendon sheath to support recovery of the A1 pulley and tendon without repeated cortisone.
03
FIXED LOCKING
Surgical Referral
Fixed triggering that does not respond to conservative or regenerative measures is most efficiently treated with A1 pulley release. We refer appropriately when surgery is the right answer.
How Joint Freedom Compares
What you are actually weighing when you consider your options for trigger finger.
 | Cortisone Shot | Surgery | |
|---|---|---|---|
| What it does | Reduces tendon sheath inflammation, supports recovery of smooth tendon gliding without surgery or repeated cortisone | Reduces sheath inflammation temporarily | Releases the A1 pulley to allow free tendon gliding |
| Recovery time | None to minimal | None | Days for light activity; weeks for full function |
| Addresses root cause | Yes | No | Yes |
| Long-term results | Durable relief for mild to moderate presentations | High recurrence; tendon weakening with repeated injections | High success rate; minor procedure under local anesthesia |
| Risk of side effects | Minimal | Fat pad atrophy, tendon weakening with repeated use | Infection, stiffness, nerve injury (rare) |

Questions About Trigger Finger
Answers from our clinical team.
Yes. That locking-and-snapping sensation is the hallmark of trigger finger. The flexor tendon is catching on a thickened A1 pulley as it moves through the sheath. The snapping is the tendon releasing past the restriction.
Repetitive gripping, prolonged hand tool use, and conditions that thicken connective tissue (diabetes, rheumatoid arthritis, hypothyroidism) all predispose to trigger finger. In many patients, no single identifiable cause is found.
Yes. Class IV laser reduces inflammation in the tendon sheath and can reduce the thickening that causes catching. For mild to moderate cases, a laser series often resolves or significantly reduces symptoms without injection.
Most hand surgeons limit cortisone to 2 to 3 injections in the same tendon sheath. Beyond that, tendon weakening and fat pad atrophy become genuine concerns. If you have already had multiple shots with recurrence, it is time to consider an alternative approach.
A1 pulley release is typically an outpatient procedure under local anesthesia. Most patients return to light activities within a few days and full function within 4 to 6 weeks. For patients who prefer to avoid surgery, regenerative approaches are worth trying first.
Yes. Laser therapy treats multiple fingers in the same session. For PRP, we typically address the most symptomatic finger first and assess response before treating others. We build the plan around your individual presentation.
Many patients notice reduced catching and stiffness within 3 to 5 sessions. A full course typically runs 8 to 10 sessions. Severe cases with fixed triggering may require longer treatment or may be better candidates for PRP.

Related Conditions We Treat
Trigger finger often co-exists with other hand and wrist conditions, particularly in patients with systemic disease.
PARENT CONDITION
Wrist and Hand Pain
Trigger finger is one of the most common hand conditions at Joint Freedom. The wrist and hand pain overview covers the full range of conditions we treat.
RELATED HAND
De Quervain's Syndrome
De Quervain's involves the thumb-side tendons while trigger finger involves the flexor tendons. Both are tendon sheath conditions that respond to laser and PRP.
RELATED HAND
Carpal Tunnel Syndrome
Hand and finger symptoms from carpal tunnel are sometimes confused with trigger finger. We assess both at the same consultation when hand pain is the complaint.
RELATED
Arthritis
Rheumatoid arthritis increases trigger finger risk. When RA is the underlying driver, we coordinate care with your rheumatologist.
