A common condition when a finger, or thumb, gets stuck in a bent position, and straightening it causes a painful “snap.”
This happens when inflammation develops around the tendon inside the tendon sheath (a tissue “tube” surrounding the tendon), and is called tenosynovitis. The inflammation narrows the space between the tendon and its sheath, and the thumb or finger gets “stuck” in the bent position.
This painful condition often results from repetitive gripping motions with the hand(s).
My treatment plan includes gently adjusting the involved finger, anti-inflammatory management, and splinting of the finger in a straightened position while the inflammation resolves.
