Trigger Finger or stenosing tenosynovitis, is when a finger or thumb tendon becomes inflamed and develops a nodule. This results in difficulty in straightening the finger, often locking in a bent position. The condition is common in adults aged 40-60 and can be exacerbated by repetitive gripping or certain health conditions like diabetes or rheumatoid arthritis.
This video details the anatomy of the hand, explaining the role of tendons and sheaths in finger movement, and how thickening of these sheaths leads to Trigger Finger. It describes symptoms like pain, swelling, and a catching sensation, and the diagnostic process involving physical exams and possibly X-rays.
Treatment options vary from rest and medication to steroid injections. In severe cases, a Trigger Finger Release surgery, an outpatient procedure, is recommended. This surgery involves cutting the A1 pulley to allow the tendon to move smoothly. Post-surgery, patients usually experience quick recovery and relief from symptoms.
