|What is it?
||Trigger Finger or Thumb is a condition that
impacts ones ability to bend and straighten the finger
because of swelling in the tendon of that finger. The normal
gliding of the tendon on the bone in the finger is sometimes
described as how a fishing line is guided along a fishing
pole. The fishing pole is like the bone in the finger, the
line is like the tendon, and the rings guiding the line
along the pole are like the pulleys found in the finger.
With trigger finger, the area of inflammation along the
tendon creates a nodule that gets stuck on the pulley. When
this area finally passes through the pulley it causes a
triggering or snapping in the finger.
|Signs and Symptoms of this
- Pain and a clicking sensation when the finger or
thumb is bent
- Pain upon bending or straightening the finger or
- A snapping release of the finger when straightening
- The finger or thumb becoming locked in the bent
- Rheumatoid arthritis
- Partial tendon lacerations
- Repeated trauma from pistol-gripped power tools
- Long hours grasping a steering wheel
- Congenital Defect
|Prevention / What You Can Do
Avoiding repetitive use of certain power tools can help
prevent trigger finger. However, it is most important to
seek early treatment when signs/symptoms begin to avoid the
need for surgery.
Prognosis is good with both conservative and invasive
Rest to allow the inflammation in the tendon to decrease is
often accomplished using splinting. If this is not
successful, a cortisone injection may be used. The most
invasive treatment involves surgery to cut the pulley that
the tendon is being caught on in half so that it no longer
causes the triggering. This may be followed by therapy
depending on how severe the condition was before surgery.
Range of motion exercises are typically given.
