# the hind leg slants forward, in front of the plumb line, when viewed from the side. The cannon is unable to be put in vertical position. Also called “curby” hock, as it is associated with soft tissue injury in the rear, lower part of the hock.
# Limits the straightening and backward extension of hocks, which this limits push-off, propulsion, and speed. There is overall more hock and stifle stress.
# Closed angulation and loading on the back of the hock predisposes the horse to bone and bog spavin, thoroughpin, and curb.
