Corona (Margo coronalis)
The coronary band (coronet) is the specialized, highly vascular and innervated region at the proximal margin of the hoof wall. It is the site of continuous production of new hoof horn. The band encircles the top of the hoof capsule and is continuous with the periople. Because it is richly supplied with blood vessels and nerves, it is sensitive to trauma, inflammation, and infection. Damage to the coronary band (from overreaching, interference, abscesses that break out, or direct trauma) can produce permanent horizontal defects, cracks, or distorted wall growth as the damaged germinal tissue continues to produce abnormal horn. Severe injuries may also affect the underlying laminae and coffin bone.
Coronary-band lacerations or avulsions require careful cleaning, protection, and sometimes surgical repair or grafting. Infections (e.g., quittor involving the collateral cartilage) can extend to the coronary band. Horizontal “fever rings” or grooves often reflect a past systemic insult that temporarily affected coronary-band production.
Any cut, puncture, or severe bruise at the coronary band should be examined promptly; early treatment reduces the chance of permanent wall defects. Keep the area clean and protected while it heals. Horizontal rings in the hoof wall are a record of past stress; note when they appeared.
