The central portion lies between the lateral cartilages and immediately under the coronary cushion.

The coronary cushion being continuous with the plantar, the backward and outward movements of the latter will tend to pull upon and tighten the former, especially in front.

The previous inflammatory changes in the adjoining sensitive structures have here led to an increased secretion of horn, and a greater or less deposition of inflammatory connective tissue in the wounded coronary cushion.

Neither is treatment of any use if any great loss of the coronary cushion has occurred.

Causes.—False quarter may result from any disease of the foot that involves destruction of a portion of the coronary cushion.
