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.
摘要：
新生儿马的肌肉骨骼异常是一种常见的疾病，其中包括角状肢体畸形，有缺陷的腕骨/骨骨化，收缩的肢体和下颌/上颌前颌。本病例报告描述了骡子马驹中多种肌肉骨骼异常的表现和手术治疗。新生骡子马驹因几种肌肉骨骼异常而出现，例如与两个腕关节的矢状平面的角度偏差，后肢韧带松弛，和严重的下颌前突.然后通过应用张力正畸线来治疗下颌前突的手术治疗。术后,下颌错牙合畸形的矫正有显著改善,无需进一步矫正.其他异常情况的管理主要是保守的，有摊位休息和运动限制，生活的第一个月有了相当大的改善。因此，在骡子马驹中也可能观察到下巴畸形，并可能与多种先天性异常有关。早期识别,适当的管理，手术治疗是必不可少的。
