Navicular syndrome remains one of the most significant causes of chronic forelimb lameness in horses throughout the world.
The condition has historically been associated with degeneration of the navicular bone itself.
Although modern understanding recognizes that navicular syndrome is not a single disease entity, but rather a complex group of pathological changes involving the navicular apparatus.
These structures include the navicular bone, deep digital flexor tendon, navicular bursa, collateral sesamoidin ligaments, distal impar ligament, and surrounding soft tissues within the palmar region of the foot.
The syndrome is particularly important within farriery because hoof balance, foot conformation, and biomechanical loading all have a profound influence upon the development, progression, and management of the disease.
Navicular syndrome most commonly affects mature horses used for athletic disciplines such as show jumping, dressage, eventing, hunting, and pleasure riding.
Warmbloods, quarter horses, and Thoroughbreds appear predisposed, although the condition may occur in any breed.
Horses with upright feet, small feet relative to body size, long toes, and underrun heels are frequently associated with the disorder.
Chronic pain originating from the navicular region can severely compromise performance, welfare, and long-term soundness.
Successful management requires close collaboration between veterinary surgeons, farriers, physiotherapists, nutritionists, and owners.
Modern imaging techniques have transformed the understanding of navicular syndrome.
Historically, the condition was diagnosed primarily through radiographic changes within the navicular bone itself.
It is now understood that many horses exhibit severe lameness with minimal radiographic change, while others possess significant radiographic abnormalities without clinical signs.
Magnetic resonance imaging has demonstrated that pathology affecting the deep digital flexor tendon and navicular bursa often plays a major role in pain generation.
Appropriate trimming and shoeing techniques can reduce mechanical stress upon the navicular apparatus, improve breakover, redistribute weight, bearing forces, and enhance comfort.
Poor farriery may accelerate degeneration through excessive heel collapse, delayed breakover, and abnormal loading patterns.
