Animal Chiropractic Module 4 – Extremities Practice Exam

The main concept is identifying navicular disease by its chronic, degenerative nature of the navicular apparatus and the specific front‑limb gait abnormalities it causes. This condition typically affects one or both front feet and progresses over time, leading to persistent pain in the navicular region. The signs described—shortened forelimb stride, stumbling, pointing the foot, toe‑first landing, and a shifting leg lameness—fit navicular disease well. Pain in the navicular area alters how the horse places its foot and distributes weight, resulting in a shorter stride, a tendency to land toe‑first to minimize heel impact, occasional stumbling, and shifting weight from one limb to the other as discomfort changes with movement. Laminitis (founder) presents with different hoof and systemic signs, such as a painful, hot hoof with strong digital pulses, reluctance to move, and potential rotation or sinking of the coffin bone. Windpuffs are simply swelling around the fetlock joints, not a degenerative hoof condition. Given the chronic, bilateral presentation and the specific gait changes described, navicular disease is the best match.
