Steps to Deal With a Trigger Finger

Steps to deal with trigger finger

Steps that you can take to deal with or cure your trigger finger. We will first understand what exactly the trigger finger is. Why is your finger gets stuck in a bent position? Moreover, what are the reasons, different treatments, and exercises to deal with it?

Trigger Finger

  • A trigger finger is a condition where the involved finger will “catch” as it bends. The finger is straightening with a “pop” or a “snap”.
  • The flexor tendon becomes thick and inflamed as it passes through the tendon pulley, resulting in a thickened nodule and tendon triggering. The tendon does not glide smoothly.
  • Repetitive injuries or occupations are risk factors for trigger finger development.
  • In the trigger finger, the pain will be at the level of the A1 pulley. There will catching, clicking, and triggering with finger flexion and extension.

Symptoms of Trigger Finger You Must Know

There will be pain before triggering. Pain is typically non-specific and poorly localized. The patient will complain of catching, then locking that has fixed (typical stages of trigger finger).

  • When the tendon is unable to pass through the sheath, it might get locked. The tendon becomes tangled when it becomes inflamed.
  • However the condition is progressive and it may lead to a fixed, flexed finger.
  • It commonly affects the ring and long fingers.
  • The trigger finger is an A1 pulley problem.
  • The discomfort can found at the A1 pulley.
  • 60% or more of patients with trigger fingers usually have associated carpal tunnel syndrome.
  • Trigger finger occurs more in diabetics and more in females older than 50 years old.
  • Diabetics may experience problems with both hands and many digits.
  • Meanwhile, Nondiabetic patients have a better prognosis.
  • Diabetes is a poor prognostic indicator for non-operative treatment and these patients are prone to develop stiffness or recurrence of the condition after surgical release.

In addition to diabetes, there are some other medical conditions that can associated with trigger fingers such as:

  • Gout
  • Pseudogout
  • Rheumatoid arthritis
  • Sarcoidosis
  • Hypothyroidism

Treatment Of Trigger Finger

Conservative treatment

The duration of triggering before going to the doctor is the most important prognostic predictor for a positive outcome with non-operative treatment.

An irreducible locked trigger finger with PIP joint flexion contracture should not be treated conservatively or even with injection (it will need surgery).

  • Splinting.
  • Nonsteroidal anti-inflammatory medications (NSAIDs).
  • Rest.
  • Activity modification.


At least, this can give some relief to the patient!


Injection

  • Injection to the sheath, not into the tendon.
  • 60-80% of nondiabetic patients may get better with injection. In diabetic patients, injection is ineffective.
  • Also, try to obtain HbA1c (Hemoglobin A1c) in these patients before considering injection or any surgical intervention.
  • The injection can be given three times.
  • The majority of patients with trigger fingers get better with injection or surgery.


Surgery

  • Done if the non-operative treatment fails.
  • Involves release of the A1 pulley.
  • There is a high recurrence in diabetic patients with surgery.
  • The release of the A1 pulley can be percutaneous or open.
  • Percutaneous release of the A1 pulley can be done for the fingers but not for the thumb because the radial digital nerve almost crosses in the middle of the surgical field (it can be injured).
  • However, when releasing the A1 pulley, the release should be done at the level of the MP joint.
  • The A2 and A4 pulleys are vital structures that should not be interfered with, removed, or released.
  • Only the A1 pulley is cut and released, and the flexor tendon is released.


Surgical Release


How do you release the A1 pulley? The operation is performed under local anesthetic to allow for intra-operative examination and communication with the patient to ensure proper release.


Different Diagnosis of Trigger Finger

Lumbrical Plus Finger

When the patient tries to flex the fingers, the involved digit will be extended. Moreover, Paradoxical extension of the IP joint when attempting finger flexion.

Sagittal Band Injury

  • Sagittal band injury can give you triggering. In sagittal band injury, the snapping occurs due to subluxation and relocation of the extensor tendon.
  • You need to diagnose this condition of sagittal band injury in order to avoid unnecessary surgery for trigger finger release.
  • The snapping and subluxation of the tendon are noticed at the top of the knuckle when moving from extension to flexion.
  • The typical scenario is that the patient is unable to actively extend the finger from a fully flexed position, but the finger can be maintained in place once it is passively extended.
  • However, In both conditions of trigger finger and sagittal band injury, usually, the long finger is affected.

Joint contracture

The patient could have a trauma history. The patient will be unable to actively or passively extend the finger.

Flexor Tenosynovitis

The four positive Kanavel signs:

  • Fusiform swelling of the finger.
  • Flexed posture of the finger.
  • Tenderness along the sheath of the finger.
  • Inability to actively extend the finger with intense pain when attempting to straighten the finger.

Flexor Digitorum Profundus Avulsion

However, the avulsed tendon ends can retract proximally and may become entrapped at the level of the PIP joint, causing flexion contracture of the PIP joint.

Posterior Interosseous Nerve Syndrome

With posterior interosseous nerve syndrome, there will be a lack of extension of the fingers and the finger may have a flexed posture.


Tenodesis is present with nerve injury, but not with tendon rupture.


How Exercise Can Help


Trigger finger inflammation can cause discomfort, soreness, and reduced motion.


Other signs and symptoms include:


Therefore, a hump or lump at the base of your affected thumb or finger a clicking, popping, or snapping sounds or sensation when you move your finger inability to straighten your finger after bending it.
