The fibrocartilaginous volar plate of the thumb interphalangeal joint is anatomically quite similar to the volar plate of the digital proximal interphalangeal joint. Due to this similarity, Eaton's technique of volar plate arthroplasty may also be utilized in fracture-dislocations of the thumb Cited by: 1. Apr 29, 2018 · Volar Plate Injury: Thumb.
