What is Trigger Finger?
Trigger Finger (stenosing tenosynovitis) is a condition in which the flexor tendon thickens and cannot glide freely through the A1 pulley. The finger "locks" in a flexed position and extends with a characteristic click or does not extend at all.
The condition affects 2-3% of the population, more commonly women aged 40-60. In diabetes, the risk increases to 10%. It may affect multiple fingers simultaneously.
Stages (Quinnell classification):
- I — pain, nodule, without locking
- II — click during movement, finger extends independently
- III — locking, finger extends only passively (with the other hand)
- IV — fixed flexion contracture
Symptoms:
- Clicking during finger extension
- Locking in flexed position
- Painful nodule at the base of the finger on the palm
- Morning stiffness, worsening after rest
- Pain when gripping objects
Facts
- ICD-10: M65.3
- Prevalence: 2-3% of population
- In diabetes: up to 10%
- Gender: women 2-6 times more often
- Most common: ring finger and thumb
How MIBRAR® treats Trigger Finger
Ultrasound Diagnosis
Sono Control Arm™ visualizes the thickened tendon, A1 pulley, and nodule presence — dynamically during finger flexion-extension.
Obtaining Concentrates
CGF — anti-inflammatory factors to reduce tendon swelling. Lipogems® — stem cells for regeneration and normalization of gliding.
Injection into Tendon Sheath
Under ultrasound guidance, concentrates are injected into the tendon sheath under the A1 pulley — precisely into the impingement zone. Multiple fingers are treated in one procedure.
Restoration of Gliding
Anti-inflammatory factors reduce tendon swelling, stem cells restore normal structure. The finger flexes and extends freely again without clicking.
