What causes a volar plate injury?
The volar plate is a ligament which sits at the front of the middle joint. Volar plate injuries occur when the finger is hyperextended eg. catching a ball. The ligament can pull off by itself or with a piece of bone called and avulsion fracture.
What are the symptoms?
Volar plate injuries result in pain and swelling at the middle joint and difficulty with bending and straightening the finger.
How is a volar plate injury treated? 
A splint will be fabricated to prevent the finger from extending fully at the middle joint to allow the ligament to heal. This will need to be worn full time for 2-3 weeks but straps can be removed for exercises.
