Answer :
Final answer:
Flexion of the proximal interphalangeal (PIP) joint indicates boutonnière deformity.
Explanation:
Boutonnière deformity is a condition affecting the fingers, particularly the middle joint of the finger known as the proximal interphalangeal (PIP) joint. When a person experiences flexion at the PIP joint, it is a key indication of boutonnière deformity.
This condition is characterized by a central slip disruption, often caused by trauma, leading to the extension of the outermost joint (distal interphalangeal or DIP joint) and flexion of the middle joint (PIP joint), resembling the shape of a "buttonhole" or "boutonnière."
Understanding the specific joint involved in boutonnière deformity is vital for accurate diagnosis and appropriate treatment. The deformity can impair hand functionality and cause discomfort. Early identification and appropriate medical intervention, such as splinting and therapy, are essential to prevent further progression and improve outcomes for individuals with boutonnière deformity.
