What is the function of the distal interphalangeal ligaments?

The distal interphalangeal ligaments bind the bones of the coffin joint, linking the short pastern bone to the coffin bone. Their primary job is to stabilize this joint under load and keep the distal phalanx aligned with the middle phalanx, preventing excessive movement that could disrupt the coffin structure. This binding function directly matches the role of “binding the short pastern and coffin together.” They aren’t responsible for producing synovial fluid, charting fetlock stability, or directly supporting the navicular bone.
