Scoliosis is a musculoskeletal alteration characterized by lateral deviation and abnormal rotation of the vertebral column, considered a three-dimensional deformity that may occur due to congenital alterations, hereditary factors, vertebral development disorders or acquired injuries. This report describes the case of a Creole male sheep with an evident spinal deformity compatible with scoliosis. During the anatomopathological evaluation through necropsy, structural alterations in the vertebral region were observed, as well as the presence of myiasis located in superficial tissues, evidenced by the presence of dipteran larvae in an injured area. The association between a locomotor alteration and a secondary parasitic infestation demonstrates the importance of complete clinical and pathological examination in production animals to determine the possible causes and consequences of the lesions found.

La columna vertebral constituye una estructura fundamental del aparato locomotor debido a que proporciona soporte corporal, protege la médula espinal y permite la movilidad del animal. Durante el desarrollo embrionario, la formación adecuada de las vértebras depende de procesos coordinados de segmentación y osificación; cualquier alteración durante estas etapas puede originar deformaciones vertebrales.
La escoliosis se define como una deformidad tridimensional de la columna vertebral caracterizada por una desviación lateral acompañada de rotación vertebral. Esta alteración puede presentarse por causas congénitas relacionadas con defectos en la formación o segmentación vertebral, así como por causas adquiridas asociadas a traumatismos, enfermedades neuromusculares o alteraciones del crecimiento.
Desviación lateral anormal del eje de la columna vertebral.
Debe distinguirse de la cifosis y de la lordosis, que alteran el eje en otros planos.
La forma de la columna no determina automáticamente el origen congénito o adquirido de la lesión.
