Primer reporte de necrosis avascular de cabeza femoral en una cabra (Capra aegagrus hircus) en el Perú

First report of avascular necrosis of the femoral head in a goat (Capra aegagrus hircus) in Peru

Se reporta el caso de una cabra macho de raza alpina de 7 meses de edad, que presentaba claudicación del miembro posterior derecho sin causa definida. Se realizaron los exámenes clínicos y radiográficos, sugiriendo luxación traumática o necrosis avascular de cabeza femoral con consecuente enfermedad degenerativa articular. Se realizó tratamiento quirúrgico mediante artroplastia por excisión de cabeza y cuello femoral. El estudio histopatológico mediante la coloración de hematoxilina y eosina describió: hueso necrótico, lagunas conteniendo osteocitos necróticos, además de médula ósea necrótica. Esta información comprobó el diagnóstico de necrosis avascular de la cabeza y cuello femoral. En el post quirúrgico, la recuperación clínica del paciente se consideró buena, mitigando el dolor y mejorando la función del miembro afectado. El presente caso se trata del primer reporte de esta enfermedad en caprinos en el Perú.
