Navicular syndrome, often called navicular disease, is a syndrome of lameness problems in horses. It most commonly describes an inflammation or degeneration of the navicular bone and its surrounding tissues, usually on the front feet. It can lead to significant and even disabling lameness. [1]
A lameness exam is used to try to pinpoint the cause of lameness in the horse, which subsequently guides treatment. It is the first step to evaluate decreased performance in an equine athlete, even if the horse does not appear overtly lame, to rule out any pain-associated cause. Lameness exams are also a key component of the pre-purchase ...
The treatment of equine lameness is a complex subject. Lameness in horses has a variety of causes, and treatment must be tailored to the type and degree of injury, as well as the financial capabilities of the owner. Treatment may be applied locally, systemically, or intralesionally, and the strategy for treatment may change as healing progresses.
Navicular syndrome may be responsible for as much as 1/3 of all cases of lameness in horses, but radiographic changes in the navicular bone do not always provide a definitive diagnosis. Newer imaging techniques have shown that damage to the soft tissues in the region may be significant contributors to lameness and that multiple causes may ...
A flexion test is a preliminary veterinary procedure performed on a horse, generally during a prepurchase or a lameness exam. The purpose is to accentuate any pain that may be associated with a joint or soft-tissue structure, allowing the practitioner to localize a lameness to a specific area, or to alert a practitioner to the presence of sub-clinical disease that may be present during a pre ...
Lameness in horses is movement at an abnormal gait due to pain in any part of the body. It is most commonly caused by pain to the legs or feet. Lameness can also be caused by abnormalities in the nervous system. While horses with poor conformation and congenital conditions are more likely to develop lameness, trauma, infection and acquired ...
Tiludronate has been used primarily for the treatment of diseases in horses that are associated with inappropriate osteolysis, such as navicular disease [4] and osteoarthritis. It has specifically been shown to improve lameness in horses with osteoarthritis of the distal hock joints (bone spavin) [5] and vertebral column. [6]
The severity of lameness is qualified using the Obel grading system: [16] Obel grade 1: Horse shifts weight between affected feet or continuously lifts feet up. It is sound at the walk but displays a shortened stride at the trot. Obel grade 2: Horse displays a stilted, stiff gait, although is willing to walk.
