Magnetic Resonance Imaging and Scintigraphic Findings in Five Horses With Obscure Foot Lameness Associated With Penetrating Injuries

摘要

Magnetic resonance imaging (MRI) has diagnostic and prognostic value in evaluating acute and chronic penetrating injuries to the foot. The structures involved can be imaged in detail, and therapy can be planned and monitored. Penetrating wounds of thesole and frog in the hooves of the horse are common and potentially serious injuries.1'2 The exact location of penetration of the foot is a major prognostic indicator. Puncture wounds to the frog (Cuneus ungulae) and the collateral sulci have a much graver prognosis than similar wounds to the sole,2 because they put the deep digital flexor tendon (DDFT), the Bursa podotrochlearis, the distal sesamoid bone (DSB), the distal sesamoidean impar ligament (DSIL), the distal interphalangeal (DIP) joint, the digital flexor tendon sheath, and the distal phalanx at risk.
