Paries ungulae
The hoof wall is the hard outer layer of the foot. It grows continuously from the coronary band and is composed of tubular and intertubular horn. It provides the main weight-bearing surface of the unshod foot and protects the internal structures. The wall is tightly attached to the coffin bone through the sensitive and insensitive laminae. This laminar attachment suspends the coffin bone inside the capsule and must withstand large mechanical forces during locomotion. Wall quality, thickness, and growth rate are influenced by genetics, nutrition, environment, and overall health. Cracks, flares, or thin, weak wall can compromise foot stability. In laminitis the laminar attachment fails, allowing the coffin bone to rotate or sink within the capsule.
Wall cracks that reach the coronary band or involve sensitive tissue can cause lameness. Flares and underrun heels alter loading. Laminitis produces characteristic changes in wall growth and the relationship between the wall and the coffin bone. Radiographs and careful farriery are central to management.
Inspect the wall regularly for cracks, flares, or abnormal rings. Keep the coronary band healthy and free of injury. Sudden lameness with heat or digital pulse in the foot needs prompt veterinary attention, especially if laminitis is possible.
