Ectrodactyly in a West Highland white terrier.

A case of monomelic forelimb ectrodactyly (lobster-claw deformity) in a West Highland white terrier is reported. Clinical and radiographic findings are described. The dog was treated with a soft tissue reconstruction of the cleft. It later developed a slight varus-type deformity at the carpus but remained sound with occasional bouts of mild lameness following vigorous exercise. To the author's knowledge, this is the first reported case of canine ectrodactyly treated by simple cleft reconstruction, and only the second report of ectrodactyly in this breed.
