Score: 4.6/5 (72 votes)
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). When the finger is bent back too far, one or more of the collateral ligaments can also be torn.
What is the volar plate and what does it do?
The volar plate prevents the finger from bending backwards and helps stabilize the proximal interphalangeal (PIP) joint, the middle joint of the finger.
How long does a volar plate injury take to heal?
Most volar plate injuries heal without any problems in about six weeks. You should regain movement quickly with regular exercise (within four weeks). However, it may take several months for your symptoms to settle completely – these can include pain or discomfort, stiffness, decreased strength and swelling.
Where is the volar plate located?
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.
How is volar plate injury diagnosed?
Diagnosis of volar plate injury is based on history and examination. There is tenderness maximally over the volar PIPJ, pain on passive hyperextension of the injured finger, possible PIPJ instability, and loss of pinch power.
Volar Plate Avulsion Fracture Emergency
What happens when you bend your finger back?
When the finger is bent back too far, one or more of the collateral ligaments can also be torn. If the collateral ligaments are torn, there could be an increase in side-to-side movement of the joint. As the volar plate is stretched and torn, it may also pull off a small piece of bone.
What causes Jersey finger?
A “jersey finger” occurs when the tendon responsible for flexing the tip of the finger is torn. The most commonly injured finger is the ring finger. The torn tendon can slide as far back as the palm. Athletes participating in sports requiring frequent grasping.
What is volar plate arthroplasty?
Volar plate arthroplasty (VPA) is a treatment option for comminuted and unstable dorsal fracture-dislocations of the proximal interphalangeal joint (PIP).
What is the volar?
: relating to the palm of the hand or the sole of the foot specifically : located on the same side as the palm of the hand.
What is the volar plate made of?
A new volar plate made of carbon-fiber-reinforced polyetheretherketon for distal radius fracture: analysis of 40 cases.
Will a chipped bone heal itself?
Bones are very flexible and can withstand a lot of physical force. However, if the force is too great, bones can break. A broken bone or fracture can repair itself, provided that the conditions are right for the break to heal completely.
What is a volar plate release?
This involves freeing up thickened scar tissue on the front of your finger to allow your joints and tendons to glide more normally.
What dislocated finger feels like?
Symptoms of a Dislocated Finger
A dislocated finger is usually obvious. The finger appears crooked, swollen, and is very painful. It may be bent upward or at strange angles. You probably won't be able to bend or straighten the finger if it is dislocated.
What causes mallet finger?
In a mallet injury, when an object hits the tip of the finger or thumb, the force of the blow tears the extensor tendon. Occasionally, a minor force such as tucking in a bed sheet will cause a mallet finger.
Can you hyperextend a finger?
What can cause a finger hyperextension injury? Hyperextension of the finger usually occurs at the knuckle joint (MCP) or at the tip of the finger (mallet finger). This often occurs from catching a fast paced ball and is therefore common in cricketers, goalkeepers and basketball players.
How did gamekeeper's thumb get its name?
Gamekeeper's thumb is an insufficiency of the ulnar collateral ligament (UCL) of the metacarpophalangeal (MCP) joint of the thumb. Campbell originally coined the term in 1955 because the condition was most commonly associated with Scottish gamekeepers (especially rabbit keepers) as a work-related injury.
What does volar angulation mean?
[17,18] A negative volar tilt indicates dorsal angulation of the distal, radial articular surface (see image below). The volar tilt, or palmar/volar inclination, is an angle between a line drawn perpendicular to the long axis of the radius and a tangential line drawn along the radial articular surface.
Where does the word volar come from?
volar (adj.)
1809, from Latin vola "the hollow of a hand or foot" + -ar.
What is a volar wrist ganglion?
Volar retinacular cysts are tender masses (ganglion cysts) that typically present near the base of the finger on the palm side (volar), and, although benign, can cause pain, especially when gripping an object.
What is Hemi hamate arthroplasty?
Hemi-hamate arthroplasty is a reconstructive option best suited for comminuted or chronic unstable fractures of the volar articular surface of the middle phalanx at the PIP joint. These fracture types often involve 50 % or more of the palmar articular surface or require 30° or more of flexion to maintain reduction [3].
What is arthroplasty in surgery?
Arthroplasty is a surgical procedure to restore the function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used. Various types of arthritis may affect the joints.
What is osseous avulsion?
An avulsion fracture is an injury to the bone in a location where a tendon or ligament attaches to the bone. When an avulsion fracture occurs, the tendon or ligament pulls off a piece of the bone.
What is swan neck?
Swan-neck deformity is a bending in (flexion) of the base of the finger, a straightening out (extension) of the middle joint, and a bending in (flexion) of the outermost joint.
What is a tuft fracture?
Distal Phalanx
A tuft fracture is frequently an open fracture due to its common association with injury to the surrounding soft tissues or nail bed. Even without surrounding soft tissue injury, the fracture is considered open in the presence of a nail bed injury.
What happens if you dont treat jersey finger?
If the Jersey Finger is left untreated it will have functional consequences on the whole hand. It can affect the grip strength and the capacity to handle objects. Initially rest and ice are suggested to help reduce inflammation and decrease pain but MD consultation should shortly follow the injury.
