Trigger Finger: A Treatable Tendon Problem With a Non-Surgical Solution Worth Exploring.
Trigger finger — medically known as stenosing tenosynovitis — occurs when inflammation and thickening of the tendon sheath around a flexor tendon causes the finger to catch, lock, or snap when bending or straightening. It is a common, painful, and often progressive condition.
At Palm Beach Regenerative, Dr. Ghattas offers image-guided orthobiologic treatment as an alternative to corticosteroid injections and surgical release in appropriately selected patients.
Results vary. Not all patients are candidates. Dr. Ghattas will discuss realistic expectations for your specific condition.
Understanding the Condition
What is trigger finger — and what causes it?
Each finger flexor tendon passes through a series of tight fibrous tunnels (pulleys) that hold the tendon against the bone as the finger moves. In trigger finger, the tendon sheath surrounding this pathway becomes inflamed and thickened — narrowing the tunnel. The tendon develops a nodule at the site of friction and can no longer glide smoothly through the sheath. The result is a catching, locking, or triggering sensation when the finger is flexed or extended — and in advanced cases, the finger becomes locked in a bent position.
Any finger can be affected, though the ring finger and thumb (trigger thumb) are most common. Trigger finger is more prevalent in patients with diabetes, rheumatoid arthritis, or hypothyroidism, and in individuals whose work or hobbies involve repetitive gripping.
GRADING
Severity grading — how bad is it?
| Grade | Presentation | Treatment consideration |
|---|---|---|
| Grade 1 — Pre-triggering | Pain and tenderness at A1 pulley; no triggering yet | Conservative care; orthobiologics may prevent progression |
| Grade 2 — Active triggering | Finger catches but can be straightened without assistance | Image-guided PRP or prolotherapy to tendon sheath; good candidate range |
| Grade 3 — Passive triggering | Finger locks; requires other hand to straighten | Orthobiologics in selected cases; surgical release discussed honestly |
| Grade 4 — Fixed contracture | Finger cannot be fully extended even passively | Surgical release typically more appropriate; referral provided |
Grade 1 — Pre-triggering
Presentation: Pain and tenderness at A1 pulley; no triggering yet
Treatment consideration: Conservative care; orthobiologics may prevent progression
Grade 2 — Active triggering
Presentation: Finger catches but can be straightened without assistance
Treatment consideration: Image-guided PRP or prolotherapy to tendon sheath; good candidate range
Grade 3 — Passive triggering
Presentation: Finger locks; requires other hand to straighten
Treatment consideration: Orthobiologics in selected cases; surgical release discussed honestly
Grade 4 — Fixed contracture
Presentation: Finger cannot be fully extended even passively
Treatment consideration: Surgical release typically more appropriate; referral provided
Catching or locking
Description: Finger catches during flexion or extension; may snap free
Morning stiffness
Description: Worse in the morning or after periods of inactivity
Nodule at base of finger
Description: Palpable tender nodule at the A1 pulley (palm base of finger)
Pain with gripping
Description: Discomfort with gripping, pinching, or prolonged use of the hand
Locked position
Description: In advanced cases, the finger becomes stuck in a bent position
Splinting
What it does: Resting the finger in extension overnight
Limitation: May relieve symptoms temporarily; does not address tendon sheath inflammation
NSAID medications
What it does: Oral anti-inflammatories
Limitation: Systemic side effects; limited local effect on tendon sheath
Corticosteroid injection
What it does: Steroid injected into tendon sheath
Limitation: Provides temporary relief in many patients; high recurrence rate; repeated injections may weaken tendon; diabetes patients respond poorly
Surgical release (A1 pulley release)
What it does: Open or percutaneous division of the pulley
Limitation: Effective but invasive; recovery time; risk of nerve injury, infection, bow string deformity; general/regional anesthesia required
SYMPTOMS

Conventional Options
Standard treatments and their limitations
Conventional treatment follows a stepwise approach from conservative measures to surgery. Each step has meaningful limitations that drive patients toward exploring alternatives.
| Treatment | What it does | Limitation |
|---|---|---|
| Splinting | Resting the finger in extension overnight | May relieve symptoms temporarily; does not address tendon sheath inflammation |
| NSAID medications | Oral anti-inflammatories | Systemic side effects; limited local effect on tendon sheath |
| Corticosteroid injection | Steroid injected into tendon sheath | Provides temporary relief in many patients; high recurrence rate; repeated injections may weaken tendon; diabetes patients respond poorly |
| Surgical release (A1 pulley release) | Open or percutaneous division of the pulley | Effective but invasive; recovery time; risk of nerve injury, infection, bow string deformity; general/regional anesthesia required |
THE PBRSS APPROACH
Image-guided orthobiologic treatment for trigger finger
Rather than mechanically dividing the pulley or suppressing inflammation with steroids, our approach uses image-guided orthobiologic injections to target the inflamed tendon sheath directly — supporting your body's natural tissue response while allowing the tendon to move more freely within the sheath.
1) Ultrasound-guided PRP to the tendon sheath
Platelet-rich plasma is delivered directly into the tendon sheath surrounding the affected flexor tendon under real-time ultrasound guidance. This allows precise placement at the A1 pulley — the site of maximum thickening — without the tendon-weakening risks associated with repeated corticosteroid injection. Many patients with Grade 2 and selected Grade 3 trigger finger respond well to this approach.
2) Tendon sheath hydrodissection
Image-guided hydrodissection uses a small volume of fluid injected under pressure to gently release adhesions between the thickened sheath and the tendon, restoring gliding freedom. This technique is particularly useful when the tendon is mechanically tethered within a fibrotic sheath and can be combined with PRP in the same procedure.
3)Prolotherapy to the A1 pulley region (selected cases)
In patients with significant ligamentous laxity or chronic low-grade inflammation around the pulley, prolotherapy to the fibrous structures of the A1 pulley region may complement the tendon sheath treatment. Dr. Ghattas determines the appropriate combination based on ultrasound findings at the time of evaluation.
4) Iatrogenic (post-surgical)
Slippage developing after spinal surgery, typically laminectomy, that destabilized the posterior elements. Adjacent segment disease after fusion is a related presentation.
AM I A CANDIDATE?CH
Candidacy for trigger finger treatment
The root problem in degenerative spondylolisthesis is instability—the segment’s supporting structures (facet joints, posterior ligaments, multifidus) are no longer holding the vertebra in position. Our FSU treatment approach targets each of these structures to support your body’s natural stabilizing capacity, reduce inflammation, and decrease pain without surgery in carefully selected candidates.
May be appropriate if you:
- Have Grade 1, 2, or selected Grade 3 trigger finger
- Have not responded adequately to splinting or conservative care
- Have had corticosteroid injections with recurrence or poor response
- Have diabetes (which reduces corticosteroid effectiveness)
- Want to explore options before considering surgical release
May not be appropriate / surgical referral recommended if you:
- Have Grade 4 fixed contracture that cannot be passively extended
- Have had multiple failed conservative treatments including prior injections
- Have significant tendon nodule causing mechanical block unlikely to resolve without release
- Have a condition requiring surgical correction of the pulley anatomy
- Prefer the high success rate and definitive nature of surgical release
