The talus bone, calcaneus, and navicular bone are considered the proximal row of tarsal bones. Naviculectomy or simply navicular excision represents a form of mid-tarsal resection arthroplasty. In navicular suspensory desmotomy, the ligaments supporting the navicular bone are severed. A preexisting navicular bone fracture was also repaired. The main portion of the muscle inserts into the tuberosity of the navicular bone. The tibialis posterior is the only muscle that attaches to the navicular bone. Osteochondrosis can also contribute to navicular syndrome and Wobbler disease. Knowledge of equine forelimb anatomy is especially useful for understanding navicular syndrome. Below the navicular bone is the navicular bursa. Both tarsal coalition and an accessory navicular can be confirmed by X-ray. It is most commonly used for animals suffering from navicular syndrome and suspensory ligament desmitis. Each hind limb of the horse runs from the pelvis to the navicular bone. Below these bones are the navicular bone and the distal phalanx. Another main factor is the tension placed on the ligaments that support the navicular bone. His season was cut short by a fractured navicular bone in his left foot.
