The volar plate is a fibrocartilaginous structure firmly attached to the base of the proximal phalanx. Its origin, just proximal to the metacarpal head, is thin and diaphanous; this allows hyper-extension of the MCP joint, but it is also the part of the joint most susceptible to injury during dislocations. The deep transverse metacarpal ligaments further stabilizes the volar plates of the neighbouring MCP joint.
Volar plate sprains occur are common in sports (volleyball, basketball, rugby and football) and can cause pain for months (Chick, 2013).
Management involves using the PRICE regime, stabilizing the joint with splinting or bracing and avoiding aggravating activities. Surgical intervention may be required if injury is severe.
