Volar Plate Avulsion Injury refers to an acute hyperextension of the dense ligament that covers the palm-side of each and every finger and thumb joint. Often accompanied by a shearing off of small pieces of the phalanges, this condition is marked by pain, swelling, tenderness and joint instability. The volar plate is a thick ligament that connects two bones in the finger. A volar plate injury is commonly called a jammed finger or sprain. This happens when the finger is bent backward too far hyperextended. These injuries can also lead to a fracture break called an avulsion fracture. Volar plate avulsion fractures of the distal phalanx that are seen acutely can be reduced and DIP joint stabilized by first obtaining a closed reduction and then securing the reduction with percutaneous pinning of the DIP joint. Splinting alone of the reduced fracture. Classification of avulsion fractures of the volar plate Avulsion fractures of the volar plate are very common injuries, often resulting from sporting injuries and usually involving the middle and ring fingers. Several classification systems for them have been proposed. The Eaton classification is very useful for practical purposes. Severity of Volar Plate injury can range from minor stretching sprain or tearing of the ligament, right up to an avulsion fracture where the ligament has pulled off a piece of bone from the joint surface of the middle phalanx. Clinical Examinations. Your hand therapist can.
