Untreated or late-treated foot rot, complicated sole ulcer, white line abscess that extends into retroarticular structures, and puncture wounds may all result in necrosis and or infection of structures important for weight bearing. These problems have in common severe pain that is not relieved by hoof blocks or analgesic medication. Specific diagnosis of the problem may be aided by using a probe to explore fistulous tracts, by inserting a hypodermic needle (14 or 16 g) into joints or tendon sheaths, but rarely requires X-radiography. Cows suffering from deep sepsis are truly suffering and a decision should be made at the first recognition of this problem to either euthanize, slaughter, or perform surgery. Too many cases receive no treatment or systemic antibiotics in the hope that the problem will somehow resolve spontaneously. These cows deserve a more humane approach.
Surgery of the Digit
Anesthesia is most easily performed by intravenous infiltration of lidocaine distal to a tourniquet on the metatarsus or metacarpus. Lidocaine without epinephrine, 20 to 30 ml, is infused using a butterfly catheter (19 g, 15 to 25 cm). Any accessible vein will result in complete anesthesia of both digits after a few minutes. If no vein can be found, regional perfusion above the intended surgical site is an alternative. The distal limb is scrubbed and disinfected as for any surgery but usually not shaven as the hair is typically very short or absent. Surgical procedures are commonly done in the field and are considered "clean" procedures but not sterile. The goal is to debride necrotic tissues and provide drainage for pus and exudate. If a hoof block is to be used as part of the therapy it should be attached before the surgery since adhesives require dry hoof to bond. Injecting the lidocaine followed by applying the block or scrubbing the area insures adequate time for diffusion of the anesthetic to all tissues distal to the tourniquet.
