Does the thumb have a volar plate?

Does the thumb have a volar plate?

The fibrocartilaginous volar plate of the thumb interphalangeal joint is anatomically quite similar to the volar plate of the digital proximal interphalangeal joint.

What is the volar plate of the thumb?

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.

Where is the volar plate of thumb?

The volar plate is a strong ligamentous structure on the underside of the finger at the point where the proximal and middle phalanx bones meet, called the proximal interphalangeal joint (or PIP joint).

What is the role of the volar plate?

The volar plate prevents the finger from bending backwards and helps stabilize the proximal interphalangeal (PIP) joint, the middle joint of the finger.

What is volar plate arthroplasty?

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.

How many volar plates are there?

In the MCP joints, the four volar plates of the fingers and the capsules within which they lie are blended with and interconnected by the deep transverse metacarpal ligament which ties the metacarpal heads together.

What is volar aspect?

The volar aspect of the wrist includes the radius and ulna. The carpal bones are the scaphoid, leonate, triquetrum, pisiform, trapezium,trapezoid,capitate,hamate. An important structure in the volar aspect of the wrist is the Carpal tunnel.

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.

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 plating?

Volar locking plates or distal volar radial anatomical plates are the most commonly used metallic device in the open reduction and internal stabilization of distal radius fractures. These devices allow immediate postoperative return of motion, and are good at preventing angular displacement.

What is the volar plate made of?

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 is volar Barton fracture?

Description. Barton fracture: Intra-articular fracture of the distal radius with subluxation or dislocation of the radiocarpal joint in the direction of the fracture fragment. Either the ventral (anterior/volar) or dorsal (posterior) aspect of the radiocarpal joint is fractured.

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 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.

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 surface of the hand?

Can an avulsion fracture get worse?

The pain in your injured limb gets worse even after you rest and take medicine. The skin, toes, or fingers of your injured limb become swollen, cold, or blue.

How do you treat avulsion fracture in finger?

Treatment of an avulsion fracture typically includes resting and icing the affected area, followed by controlled exercises that help restore range of motion, improve muscle strength and promote bone healing. Most avulsion fractures heal very well without surgical intervention.

What happens if you don’t treat jersey finger?

In some cases, the flexor tendon may only be partially torn. When this happens, it may still be possible to bend the finger but only slightly. These types of injuries are often the most difficult to diagnose and, if left untreated, may lead to a complete rupture.

How do you fix a jersey on your finger?

Will jersey finger heal on its own?

If the injury involves a full tendon rupture or a rupture with a bone chip attached, the finger will not heal on its own. Surgery will be required to repair soft-tissue damage and restore your finger’s ability to bend or move.
