Simultaneous dislocation of both interphalangeal joints in a finger.

Unlike dislocations of the distal or proximal interphalangeal joints, the simultaneous dislocation in a single finger of both seems to be a rare occurrence. Reduction and checking of the collateral ligament, extensor tendon, and volar plate, followed by 3 weeks of splinting in the intrinsic plus position seems to be the treatment of choice.
