Infectious tenosynovitis in 2.5% to 9.4% of all hand infections. Kanavel's cardinal signs are used to diagnose infectious tenosynovitis. They are: tenderness to touch along the flexor aspect of the finger, fusiform enlargement of the affected finger, the finger being held in slight flexion at rest, and severe pain with passive extension.
The technique of thread trigger finger release is the application of Guo Technique [2] and the procedure is similar to that of the thread carpal tunnel release. [ 3 ] The successful rate of TTFR is high and there are almost no complications such as incomplete release, neurovascular or flexor tendon or A2 pulley injury, infection, bow string, or ...
Finkelstein's test was described by Harry Finkelstein (1865–1939), an American surgeon, in 1930. [5]A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.
