Tendon Sheath Syndrome of Brown, also known as Stenosing Tenosynovitis or Trigger Finger, refers to a common condition characterized by the inflammation and thickening of the tendon sheath, which surrounds and protects tendons in the fingers or thumb. The condition is named after Dr. Norman T. Brown, who extensively studied and described this syndrome.
When affected by Tendon Sheath Syndrome of Brown, individuals experience difficulty in smoothly straightening or flexing the affected finger or thumb. The condition typically develops when the affected tendon becomes thickened or enlarged due to repetitive motion, overuse, or conditions like rheumatoid arthritis. The inflammation and swelling lead to narrowing of the tendon sheath, causing the tendon to get stuck or "catch" as it moves through the sheath.
Symptoms of Tendon Sheath Syndrome of Brown may include pain, tenderness, stiffness, a popping or clicking sensation, and a visible or palpable bump or nodule in the palm or finger. The condition is more prevalent in women and those aged between 40 and 60.
Treatment options for Tendon Sheath Syndrome of Brown range from conservative measures to surgical intervention. Non-surgical treatments typically include rest, splinting, applying heat or cold, and using anti-inflammatory medications. In some cases, corticosteroid injections may be administered to alleviate the inflammation. If conservative measures fail to provide relief, surgical intervention, such as a procedure known as Trigger Finger Release, may be necessary to widen the A1 pulley in the affected finger.
Overall, Tendon Sheath Syndrome of Brown is a condition that affects the smooth movement of tendons in the fingers or thumb, causing pain and functional limitations. Seeking medical advice is essential for accurate diagnosis and appropriate management.
