Palmar plate
Palmar Plate
The Palmar Plate (pronounced: PAL-mar PLATE), also known as the volar plate, is a thick, fibrocartilaginous structure found in the hand. It is located on the palmar side of the metacarpophalangeal joints (MCP) and interphalangeal joints (IP) of the fingers.
Etymology
The term "palmar" is derived from the Latin word "palma", meaning the palm of the hand. The term "plate" is used to describe the flat, plate-like structure of this part of the hand.
Function
The primary function of the palmar plate is to prevent hyperextension of the MCP and IP joints. It also serves as an attachment site for several important ligaments in the hand, including the collateral ligaments and the accessory collateral ligaments.
