The volar plate is a thick ligament that connects two bones in the finger. There are other ligaments to each side of the joint as well (collateral ligaments).
In the human hand, palmar or volar plates (also referred to as palmar or volar ligaments) are found in the metacarpophalangeal (MCP) and interphalangeal (IP) joints, where they reinforce the joint capsules, enhance joint stability, and limit hyperextension.
Volar plate injury can occur with an avulsion fracture, most commonly at the volar base of the middle phalanx (Fig 2)....Table 1.Eaton classification of volar plate injuries3Type 1Avulsion of the volar plate without a fracture or dislocation7 more rows•Jun 1, 2016
The volar plate is a small piece of ligament on the palm side of the middle joint (phalanx) on your finger. This structure helps to support the middle joint of your finger and prevents it being able to over straighten or dislocate.
The palmar carpal ligament (also volar carpal ligament or Guyon's Tunnel) is the thickened portion of antebrachial fascia on the anterior of the wrist.
Volar plating is indicated in nearly all unstable fractures of the distal radius. It is used in young and active patients for optimal reconstruction of the articular surface and restoration of bony anatomy while allowing nearly immediate, but protected, active range of motion.
The ulnar collateral ligament (UCL) is a ligament that runs on the inner side of the elbow to help support it when performing certain motions, such as throwing.
Volar plate arthroplasty is a surgical technique used to treat unstable dorsal fracture dislocations of the PIP with disruption of the volar plate complex, the collateral ligaments, and greater than 40% of the volar articular surface of the middle phalanx.
Symptoms of a volar plate injury include pain and swelling at the joint, tenderness on the palmar side of the joint, and joint instability. If the finger is dislocated, it may be noticeably out of alignment.
The collateral ligaments of the knee are located on the outside part of your knee joint. They help connect the bones of your upper and lower leg, around your knee joint. The lateral collateral ligament (LCL) runs on the outer side of your knee. The medial collateral ligament (MCL) runs along the inside of your knee.
Volar: Pertaining to the palm or the sole. For example, the volar surface of the forearm is the portion of the forearm that is on the same side as the palm of the hand.
The volar-radial zone is the front/inside of the wrist on the thumb side. Important not to miss: Carpal instability.
