Trigger Finger (Stenosing Tenosynovitis)

Trigger Finger (Stenosing Tenosynovitis)

The cause of Trigger Finger (TF), also called Stenosing Tenosynovitis, is related to an injury of a joint in the finger called the A1 pulley which may thicken, making it difficult for the flexor tendon to move through it as the finger bends to pull a trigger, grab a ski pole or a tennis racket. This condition can occur in all of your fingers, including your thumb, which is called Trigger Thumb. When the finger releases from its contraction, you may hear a popping sound and feel some pain or the finger may not straighten at all.

What are the symptoms of Trigger Finger?

  • A small lump at the base of the finger
  • Pain when straightening finger
  • Stiff finger
  • Locked finger

Is there a natural, non-surgical alternative for treating a Trigger Finger Injury?

Dr. Greenberg has been treating TF Injuries non-surgically for over twenty years. He will perform a Comprehensive Kinetic Diagnosis, including a review of your most recent radiographs. TF is easily diagnosed. He will check for tenderness near the flexor tendon sheath and look for accompanying swelling in the palm at the base of the affected finger. He will examine your kinetic chain, hand, wrist, elbow.

If you are an appropriate candidate for Kinetic Regeneration Therapy, Dr. Greenberg will treat your trigger finger with the healing and synergistic cascade of Prolotherapy, Platelet Rich Plasma (PRP) and Stem Cell Treatments.

For trigger finger, he uses Platelet-Rich Plasma treatments, to activate the patient’s own healing components to initiate healing at the A1 pulley and the flexor tendon in the affected finger. A typical treatment course may call for several injections performed every 3 weeks, depending on the patient’s progress. Dr. Greenberg will discuss the objectives of each treatment and explain the therapeutic option that is most appropriate for your case.

In order to mitigate the spread of COVID-19 in our community, any patient that enters the building will be screened for the virus by having their temperature taken and filling out a questionnaire from Main Line Health. Once inside the office, patients will be asked to wash their hands immediately and may receive another temperature check. All patients will be able to maintain a safe social distance from others, as only one patient is seen per hour. The Greenberg Regenerative staff wears their masks at all times, and also ensures that all safety protocols and guidelines per Main Line Health and the CDC are being followed. Additionally, Dr. Greenberg is fully vaccinated, which further reduces possible COVID-19 transmission. At the end of the appointment, patients have the option to take a Greenberg Regenerative Medicine hand sanitizer to allow them to remain safe and healthy.
