Interdigital fibroma is a condition most often observed in heavier weight beef breeds, particularly older bulls with widely placed claws. Occasionally, cows will develop fibromas as well. If the condition is allowed to persist, the “corn” can become ulcerated and infected due to continued contact with the ground (Figures 16.17, 16.18 and 16.19).

Figure 16.18 Interdigital fibroma can be misleading; this one does not appear to be significant until observed from the solar surface.

Surgical removal is necessary to resolve the fibroma. Anesthesia of the interdigital area can be provided by four‐point block or the use of a tourniquet and intravascular anesthesia. Removal of the prolapsed tissue is accomplished by sharp dissection followed by extraction of the fat pad. Cautery of the vascular bed is sometimes required to control excessive hemorrhage. A bandage is applied with a sterile gauze pack and changed after three days. As an aid to healing, especially in the individual with splayed toes, it is helpful to wire the toes together to reduce swelling and decrease granulation bed formation. The second bandage can be removed in 4 days, with complete healing expected within 10 days of surgery.
