Understanding navicular syndrome in horses, a common and challenging cause of forelimb lameness, and how welfare-conscious management can improve quality of life.
Navicular syndrome causes chronic pain that significantly affects horse welfare if inadequately managed. The insidious onset — gradual shortening of stride that can be mistaken for normal aging — means horses often work in pain for extended periods before diagnosis. The complexity of the condition, involving multiple structures in the caudal foot, means there is no single management approach; therapeutic success requires careful diagnosis, often with advanced imaging, and individualized treatment plans. Palmar digital neurectomy (nerve blocking) can provide pain relief but requires careful welfare monitoring thereafter, as the horse loses sensation in the affected foot and may not react normally to injuries. The welfare-positive approach balances effective pain management with honest assessment of whether continued work is appropriate, with retirement or career change considered when pain cannot be adequately controlled.
