Radiological appearance of the navicular bone

Summary

# Radiological appearance of the navicular bone The navicular bone's complex anatomy and its role in weight-bearing and locomotion make radiological interpretation a frequent clinical challenge, particularly given the high prevalence of navicular syndrome in equine practice. Biggi's work draws on specialist expertise in diagnostic imaging to provide detailed guidance on recognising normal radiological variants versus pathological changes in the navicular bone across standard radiographic projections. Key radiological features discussed include the appearance of the sagittal ridge, the flexor cortex, and various degenerative patterns—distinctions that are critical given how subtle changes can influence lameness diagnosis and prognosis. For practitioners integrating radiographic findings with clinical examination, this resource clarifies which findings carry clinical significance and which represent incidental or age-related variations without immediate functional impact. Farriers, veterinarians, and physiotherapists involved in navicular cases will benefit from improved confidence in interpreting radiographs and communicating findings with colleagues, ultimately supporting more consistent and evidence-based management decisions.
