BMC Vet Res 15 (1), 211 PubMed.Recent references from PubMed and VetMedResource.Once established the lesion is chronic and progressive.įurther Reading Publications Refereed papers.Chronic pain in the heels may → heel unloading → increased force over navicular bone → degenerative changes in navicular bone.Upright pastern conformation accompanied by long toe/low heel conformation (underrun heels) affects biomechanical relationship of the deep digital flexor tendon, navicular bursa, other soft tissue structure in the food (ie impar ligament) and navicular bone predisposing to navicular damage.

Thromboses within the navicular bone → hypertension → remodeling.

Interruption of circulation to and from navicular bone → remodeling.

Cumulative cyclic loading → sagittal bending of the navicular bone → microdamage → adaptive failure of the bone (low bone mass, poor osteocyte connectivity, low osteophyte density).

Repetitive trauma to the navicular bone during chronic repetitive loading by pressure from the deep digital flexor tendon → the development of a bursitis, tendonitis, adhesion formation within the bursa and between bursa and deep digital flexor tendon, and an inflammatory process → lameness.

Recently, advances in diagnostic imaging techniques, eg MRI scanning, have improved understanding of the pathological changes involved.

Trimming/shoeing which induces a broken-back axis to the hoof pastern region.

Soft tissue injury in the hoof misdiagnosed as navicular bone disease.

Conformation Musculoskeletal: conformation.

Unclear, repetitive trauma is a common history.
