By gently scraping back frog material, the farrier found the clear seam between the sole and the frog - the true apex - as shown in the bottom photo of the sole (brown line). This helped to guide the farrier's exploration of the true apex. A photograph of the sole taken at the time of the radiograph was adjusted to the same scale as the radiograph, and the brown line suggesting the position of the true apex projected onto the photo of the sole. On the radiograph a line was dropped down from the hairline at the toe (brown line) to indicate the approximate position of the true apex. On the radiograph the actual apex was clearly too far forwards - the true apex of the frog is always behind the tip of P3. Radiographs were taken with the actual frog apex marked with a drawing pin, and the hairline at the toe marked. In the diagram on the right, four months after laminitis and rotation the frog had stretched forwards. What is thought to be the apex of the frog should be marked when radiographs are taken so that the true and actual frog apex can be compared.

This transitional zone is marked by a color difference the frog is darker, the sole lighter.' Fig 1 in the paper illustrates this colour difference.įollowing laminitis, the frog often stretches forward.Ī line dropped down from the hairline at the toe will usually indicate the approximate position of the true apex of the frog.

In Page, Bowker, Ovenik & Hagen AAEP 1999 How to Mark the Foot for Radiography the authors find the true frog apex 'by trimming the superficial tissue at the apex of the frog to observe the frog blending to the sole. The true apex of the frog should be found by carefully trimming the frog until the line of dirt between the frog and the sole begins to disappear and the 'seam' between the sole and the frog is seen.
