Summary
# Editorial Summary: Radiological and Clinical Considerations on Navicular Disease Navicular disease remains a complex diagnosis requiring integration of radiographic findings with clinical presentation, yet these two diagnostic modalities do not always align—a challenge this 1978 study of 130 horses sought to clarify by examining how radiological changes correlate with lameness signs across different age groups. The researchers investigated whether radiographic alterations of the navicular bone could predict disease development before clinical signs emerged, whilst also exploring how workload intensity influenced the relationship between imaging findings and observable lameness. Key findings indicated that radiological changes and clinical symptoms do not necessarily progress in parallel, with age and work demands significantly modifying this interaction; importantly, the study identified radiographic features that may precede clinical lameness, offering potential for earlier intervention. For modern equine practitioners, this work emphasises that neither radiographs nor clinical assessment alone provides a complete picture of navicular status—farriers and veterinarians must evaluate horses within their age, workload, and activity context, and consider that subclinical radiographic changes warrant careful monitoring and potentially preventative management strategies to forestall progression to overt disease.

Practical Takeaways
- •Evaluate both radiological and clinical signs together rather than in isolation, as their relationship varies with horse age and workload
- •Monitor younger or recently worked horses more closely for early navicular changes, as detection at early stages may allow intervention
- •Work-load management should be considered in conjunction with radiological findings when assessing navicular disease progression and prognosis
Key Findings
- •Radiological alterations of the navicular bone correlate with clinical symptoms in horses with navicular disease
- •Age of the animal influences the relationship between radiological findings and clinical presentation
- •Work-load significantly affects the interaction between radiological and clinical manifestations of navicular disease
- •Early-stage navicular disease may be predictable through combined radiological and clinical assessment
