A traumatic rupture of the volar plate of the finger at the metacarpophalangeal (MCP) and interphalangeal (IP) joint is a common injury that can occur from a direct blow or hyperextension of the finger. The volar plate is a ligament that attaches to the base of the proximal phalanx and helps to prevent hyperextension of the joint.
Symptoms of a volar plate rupture include pain, swelling, and stiffness in the affected finger. The finger may also be unstable and feel like it's going to "pop out" of the joint. In severe cases, the joint may dislocate.
If you suspect that you have a volar plate rupture, it's important to seek medical attention right away. Your doctor will likely order an X-ray to rule out a fracture and may perform a physical exam to assess the stability of the joint.
Treatment for a volar plate rupture may include immobilization of the finger with a splint or cast to allow the ligament to heal. In some cases, surgery may be necessary to repair the ligament or reposition the joint.
If you have experienced a traumatic rupture of the volar plate of your finger at the MCP or IP joint, it's important to seek medical attention as soon as possible. With proper treatment, most people are able to fully recover from this injury and return to their normal activities.
