Además, presentó una hendidura con contenido de tejido blando entre el segundo y tercer metacarpiano. Los hallazgos fueron compatibles con ectrodactilia unilateral. Se realizó una cirugía reconstructiva mediante una artrodesis pancarpal, con relleno de hueso esponjoso y utilizando un sistema de fijación esquelética externa. Se restableció completamente la función del miembro a las 10 semanas.Palabras clave: Beagle; ectrodactilia; artrodesis; disostosis ABSTRACTThe case of a 5-month-old female Beagle with lameness of the right anterior limb and a separation defect between the second and third fingers is reported.
