Trigger or tenosynovitis, results from inflammation of the tendons and synovium (tissue that surround the tendons) in your fingers or thumb. This makesit difficult to straighten the finger or thumb.
Repetitive use, arthritis, or injury to the palm of the hand can irritate and inflame tendons and synovium of the fingers, but often the cause of the trigger finger is unknown.
Symptoms of the trigger finger usually begin as mild stiffness and swelling that can develop into locking or active triggering of the finger on flexion/extension.
Most Common Symptoms:
- Triggering of the finger
- Conservative Treatment:
- Avoid repetitive gripping (ie: Stress Balls)
- Anti-Inflmmatory Medication (ie: Motrin)
- Steroid injections
When symptoms do not improve with non-surgical treatments, surgery may be elected to open the sheath that surrounds the tendon. This enlarges the space and allows the finger to bend and straighten more normally.
