What vessels form the circumflex supply to the distal phalanx?

The distal phalanx is supplied by vessels that form a ring around it—the circumflex vessels. As the digital arteries course around the coffin bone, their circumflex branches (arteries) and accompanying veins encircle the bone to provide a continuous, circumferential blood supply to the distal phalanx and surrounding hoof structures. The terminal arch of the digital arteries is nearby and connects the digital arteries, but it isn’t the circumferential supply itself. Palmar arteries deliver more proximal blood flow, and paracuneal arteries are small branches near the coronary area, not the ring that encircles the distal phalanx.
