9.1 Relationship Between Limb Region and Nature of Corresponding Lameness

Problems originating below the level of the fetlock joint(s) usually produce weight-bearing lameness. Pathology involving structures within the horse’s upper limb often generate non weight-bearing lameness. Issues affecting the horse’s mid-limb commonly manifest as combination lameness, comprising both weight-bearing and non weight-bearing components.

As you’ll learn in ssss1 (ssss1), there is also a close relationship between the nature of a horse’s lameness and the physical design of the structure that is causing it: structures that undergo load-bearing stress (i.e. bear weight) have the capacity to produce weight-bearing lameness, whereas structures that change their shape during movement tend to generate non weight-bearing lameness (fig. 9.2).
