Ultrasonography : Radiology
If MRI is not available, ultrasonography can contribute to a diagnosis in infrasesamoidean ligamentous pain.
Other than chronic navicular lameness, true lesions of the infrasesamoidean navicular apparatus can be challenging in diagnosis and therapy. Acute onset of higher degree lameness, that does not respond to the classical infiltrations, are suspicious. Even fracture mimicking disorders with marked turning pain and positive palpation can occur. Theses lesions remain a difficult differential diagnosis.
Like in fracture detection, changes in the enthesis of affected structures might be diagnosed. See also last blog.
This is the perfect tool for triage of syndromes in the field. Transcuneal approach is appropriate to assess infrasesamoidean affections.
Foot pain is very common in horses. In most cases the differential diagnosis is not too difficult. However, true ligamentous lesions are an emergency and proper management (shoeing!!!) is only possible with appropriate diagnostic imaging.
