Observations in Horses with Lameness Abolished by Palmar Digital Analgesia

Scintigraphic examination plays an important role in the diagnosis of lameness abolished by palmar digital analgesia, particularly in horses with negative or equivocal radiographic changes. While navicular disease was a common diagnosis, third phalanx (PIII) subchondral remodeling or trauma was an important finding, may lead to later fractures of PIII, and was most common in the left front lateral and right front medial aspect of PIII.
