Description
Summary:The crab-eating fox (Cerdocyon thous) is the most common wild canid in South America. With a relative demographic stability, this animal is susceptible of being hit and falling into traps, and can suffer trauma in its thoracic limbs; therefore a specific anatomical knowledge about its muscles is necessary for medical and surgical procedures. The main aim of this research was to describe the anatomy of the extensor muscle of digit I and II of the C. thous reporting form, origin, insertion, innervation and irrigation. The forearms of six donated dead specimens from CORPOCALDAS to Caldas University were dissected from superficial to deep. In this research, the extensor muscle of digit I and II showed similar anatomical features to those reported for other species but with a variant tendinous distribution that forms from three to four branches distributed from digit I to III. Although sometimes this distribution does not exist for the digit III; this similar distribution must be reported for procedures which require this knowledge. KEYWORDS: Anatomy; Antebrachial; Canidae; Myology. El zorro perruno (Cerdocyon thous) es el canido silvestre mas comun en America del Sur, con una relativa estabilidad poblacional, pero susceptible de ser atropellado y caer en trampas, pudiendo sufrir traumas en sus miembros toracicos, por lo tanto se requiere un conocimiento anatomico especifico de sus musculos para intervenciones medicas y quirurgicas. El objetivo principal de esta investigacion fue realizar una descripcion anatomica del musculo extensor del I y II dedo del C thous, en la cual, se reporta forma, origen, insercion, inervacion e irrigacion. Se diseccionaron de superficial a profundo los dos antebrazos de seis especimenes muertos donados por CORPOCALDAS a la Universidad de Caldas. El musculo extensor del I y II dedo en este estudio presento caracteristicas anatomicas similares a las reportadas a otras especies pero con una distribucion tendinosa variante formando desde tres a cuatro ramas que se distribuyen del I al III dedo, incluso faltando a veces para el III dedo, pero de igual forma presenta una distribucion que debe ser conocida para procedimientos que requieran de su conocimiento.
