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).
Acquired hand deformity refers to the structural or functional abnormalities that develop in the hand. There are multiple varying causes of acquired hand deformity ...
[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 ...
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.
A mallet finger, also known as hammer finger or PLF finger or Hannan finger, is an extensor tendon injury at the farthest away finger joint. [2] This results in the inability to extend the finger tip without pushing it. [3]
The earlier the condition is identified, the better the chance of getting full range of motion of the finger. However, finger stiffness, Boutonniere deformity, deep space infection, tendon necrosis, adhesions, persistent infection, and need for amputation of the finger can occur. Tendon adhesion and finger stiffness are caused by the violation ...
