curb(redirected from The Curb)
Also found in: Dictionary, Thesaurus, Financial.
a thickening on the posterior surface of the tarsal joint of the horse. It is expressed externally by distortion in the region of the lower part of the fibular tarsal bone. It is caused by overgrowth of the tendons and ligaments in that area; sometimes it is the result of a congenital forward inclination of the fibular tarsal bone. Severe curb is accompanied by lameness, which reduces the horse’s working ability. As a rule, treatment is ineffective.
