ABSTRACT
Musculoskeletal abnormalities in neonate equids represent a common condition, which includes angular limb deformities, defective carpal/tarsal bone ossification, contracted limb and mandibular/maxillary prognathism. The present case report described the presentation and surgical management of multiple musculoskeletal abnormalities in a mule foal. A newborn mule foal was presented for several musculoskeletal abnormalities, such as angular deviation from the sagittal plane of both carpal joints, hind limb ligament laxity, and severe mandibular prognathism. Surgical management of mandibular prognathism was then treated through the application of a tension orthodontic wire. Postoperatively, there was a significant improvement in the correction of mandibular malocclusion and no further correction was needed. Management of other anomalies was mainly conservative, with stall rest and exercise limitations, with a considerable improvement in the first month of life. Thus, jaw malformations might be observed also in mule foals, and might be associated with multiple congenital abnormalities. Early recognition, appropriate management, and surgical treatment were essential.
