Navicular syndrome encompasses degenerative conditions of the navicular bone and surrounding structures in the equine foot, causing chronic forelimb lameness requiring long-term management.
Navicular syndrome causes chronic foot pain that significantly impacts mobility and quality of life. Affected horses show a characteristic shortened gait, toe-pointing at rest, and reluctance to work that reflect ongoing discomfort. Without treatment, the condition typically progresses. The welfare impact includes not only pain but reduced ability to move freely and perform normal activities. Management decisions involve complex tradeoffs — corrective shoeing and medication can reduce pain and maintain function, but some horses require nerve cutting (neurectomy) to remain comfortable, which carries its own welfare and safety implications since the horse loses sensation in the foot. Long-term management of navicular horses requires honest assessment of whether pain is adequately controlled and whether horses can engage in work without significant discomfort.
