Opening from the diseased bone to the surrounding soft tissue is known as what?

A cloaca is the opening through which infected bone drains into the surrounding soft tissues. In chronic osteomyelitis, a cloacal opening can form in the bone (often through the cortex or involucrum), creating a drainage point for pus to escape to the soft tissues. This distinguishes it from a sinus tract, which is the channel that carries drainage to the skin, while a sequestrum is a piece of dead bone and involucrum refers to new bone forming around that dead fragment. So the direct bone-to-soft-tissue opening is the cloaca.
