Two cases of feline ectromelia: autopodium ectromelia associated with humero-ulnar synostosis and zeugopodium ectromelia.

Congenital limb deformities are rarely reported in cats. This paper describes the radiographic findings of congenital forelimb malformations in two cats. The radiographic changes were suggestive of an autopodium ectromelia associated with humero-ulnar synostosis in one case and zeugopodium ectromelia in the other case. Congenital feline limb deformities are poorly documented and, to the authors' knowledge, this is the first time that humero-ulnar synostosis has been reported in cats.
