Unilateral forelimb partial aphalangia in a kitten

Area of Science:

• Veterinary Medicine
• Developmental Biology
• Genetics

Background:

• Congenital limb deformities are infrequently documented in feline populations.
• Aphalangia, the absence of phalanges, is a rare congenital defect across animal species.

Observation:

• A 2-month-old male kitten presented with a severely shortened forelimb ending in a stump at the carpus.
• Macroscopic examination revealed the absence of digits, with a single nail on the first phalanx and only two palmar footpads.
• Radiographic analysis confirmed the absence of phalanges, with malformed and shortened first metacarpal and incompletely ossified carpal bones.

Findings:

• The kitten exhibited a complete absence of phalanges in the affected limb.
• Skeletal abnormalities included reduced length of metacarpal bones and incomplete ossification of carpal bones.
• This represents the first reported case of congenital forelimb aphalangia in a domestic cat.

Implications:

• This case highlights the importance of recognizing rare congenital anomalies in veterinary diagnostics.
• Further research into the genetic and developmental factors underlying feline limb deformities is warranted.
• Understanding such conditions can aid in early diagnosis and management of congenital defects in cats.
