Bilateral coxofemoral dysplasia in a Mangalarga Marchador foal.

Abstract

Coxofemoral dysplasia is a condition characterized by the abnormal development and flattening of the femoral head and deformities in the acetabulum, leading to joint instability. Although described in various animal species, it is uncommon and rarely reported in horses. This article presents a case of incapacitating coxofemoral dysplasia diagnosed in a four-month-old foal Mangalarga Marchador, which exhibited lameness in the hind limbs, thoracolumbar kyphosis, gluteal muscle atrophy, and pronounced sensitivity during pelvic limb flexion. The clinical diagnosis indicative of bilateral coxofemoral dysplasia was confirmed through post-mortem examination. This case report highlights the importance of awareness and monitoring for early detection of coxofemoral dysplasia in foals.
