We're looking at an 8yo Saddlebred with navicular syndrome that had on and off lameness in the left front forelimb. A palmar digital nerve block was performed to localize the lameness. CT images show large flexor cortical erosion that communicates with the synovial invagination shown in the video. Other CT images show a large cortex defect with surrounding sclerosis and a deep penetrating synovial invagination.
