| Magnetic Resonance Imaging provides a detailed perspective on the navicular syndrome in horses |
| The navicular syndrome is a chronic bilateral forelimb lameness which is abolished by palmar digital nerve block. Its pathogenesis is not clearly understood. The aim of this study was to evaluate pathological changes in horses where chronic bilateral forelimb lameness was abolished by palmar digital nerve block. The experiment was performed on 20 horses. The animals were referred for 0.25 T MRI scanning with the use of T1-weighted, T2-weighted, STIR, X-bone and 3D HYCE sequences. In 15 horses (75%), the changes were localized in the area of the deep digital flexor. In nine horses (45%), changes were observed in the area of the collateral sesamoid ligament. In five horses (25%), the recess of the navicular bursa was enlarged and filled with large amounts of synovial fluid which was indicative of an inflammation. In 13 horses (65%), changes in the navicular apparatus were caused by widening of synovial membrane invaginations into the palmar aspect of the navicular bone. Magnetic resonance is an imaging modality which provides a detailed picture of pathological changes, supports the choice of optimal treatment, and facilitates prognosis for horse's return to use and performance. |
