Volar plate fractures are the result of hyperextension. This injury typically involve the proximal interphalangeal joint of the fingers. At this location, the volar plate (a dense fibrous band) forms a portion of the capsule. Typically, there is a small fragment of bone avulsed from the volar aspect of the base of the proximal phalanx. If not repaired, this can lead to instability.
A Wilson fracture refers to a volar plate injury to the middle phalanx of a finger.
