Boutonniere deformity is a deformed position of the fingers or toes, in which the joint nearest the knuckle (the proximal interphalangeal joint, or PIP) is permanently bent toward the palm while the farthest joint (the distal interphalangeal joint, or DIP) is bent back away (PIP flexion with DIP hyperextension).
With conditions involving nerve damage, specific tests measuring nerve capacity can act as an indication of the deformity's status. [12] Such may include electromyography (EMG) , to assess coordination between nerves and associated hand muscles, as well as nerve biopsies or conduction tests [ 12 ]

Swan neck deformity has many of possible causes arising from the DIP, PIP, or even the MCP joints. In all cases, there is a stretching of the volar plate at the PIP joint to allow hyperextension, plus some damage to the attachment of the extensor tendon to the base of the distal phalanx that produces a hyperflexed mallet finger.
[4] [16] As a result of frequent tissue injury, there can be an early onset of advanced osteoarthritis, [45] chronic degenerative joint disease, [45] swan-neck deformity of the fingers, [46] and Boutonniere deformity of the fingers. Tendon and ligament laxity offer minuscule protection from tearing in muscles and tendons, but these problems ...

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.
He would blow off his homework and then ace his tests. By the 5th grade, at the red-brick Hamilton Avenue School in nearby Greenwich, he’d published three poems in the school newspaper. One, written after a class lecture about drinking and driving, described the thoughts of a driver as he was dying in a car crash.
