Pad corns: A pain for both dog and veterinarian

Surgical excision requires either a general anesthetic or heavy sedation with medetomidine and butorphanol together with a digital nerve block, for instance. Hemostasis is achieved by an assistant pinching the caudal aspect of the pad between the index finger and thumb. A full thickness elliptical incision is then made around the corn to include a small margin of normal pad tissue, allowing the corn to be teased out from the underlying fibro-adipose tissues. The pad margins are closed with simple absorbable sutures, the author’s (Guilliard’s) preference being polyglactin. The paw needs to be covered in a protective dressing for up to three weeks and changed frequently. The sutures soon wear through and disappear.
The role of toe amputation in the management of corns is typically considered to be the treatment of last resort, since it may alter weight distribution between the remaining toes, resulting in a new corn developing on one of them. However, in the authors’ experience, this rarely occurs. This consideration should be weighed against the possibility toe amputation can render a greyhound corn- and pain-free.
A distal digital amputation through either the distal interphalangeal joint or the distal second phalanx has been advocated. This technique is more likely to be successful in digits 2 and 5, as they are not the main weight-bearing digits. However, in the author’s (Guilliard’s) experience, this has shown mixed results.
The author (Guilliard) is currently conducting trials of a novel surgical treatment for corns that involves cutting the flexor tendons. He has postulated that if the affected toe is unloaded by this method, the mechanical trauma will cease, the dog will not be lame, and the corn will grow out and not recur. The corn is not excised, but pared down only if prominent.
Short-term results to date on a small number of cases are very encouraging, with all owners reporting great improvement after only two or three days. The longest follow-up period is six months with no lameness reported.
