What is a Volar Plate Injury?
It all begins with an idea.
Volar plates are fibrocartilaginous plates that span over the bottom of the fingers joints. They are held by ligaments and the volar plate’s purpose is to reinforce the connective tissue (capsules) of the finger and thumb joints. There are 3 volar plates for each finger and 2 for the thumb. They help support and stabilize the bones of each finger and thumb.
The main function of the volar plate is to prevent hyperextension (backward bending) of the fingers and thumb. Volar plate injuries most commonly occur when fingers or thumb are forced backward too far.
Initial treatment involves splinting on the top (dorsal) side of the finger. The affected joint will be positioned in approximately 30 degrees of a bent position (flexion). Over the next 3 weeks; the splint will be adjusted until full extension (straightening of the finger) is obtained. The client is allowed to bend the finger as far as they are able - aiming for full flexion. After reaching full extension, the splint will be used for protection during the day and night.
In certain situations, the hand surgeon may decide that surgery is required. In this case, reattachment of the volar plate to the bone will occur. After surgery, your finger/thumb will be splinting to protect the repair.
