Abstract

Background: Syndactyly, also known as mulefoot, is one of the most common physical extremity malformations. In pigs, syndactyly has been associated with genetic or environmental factors and occurs as an isolated defect or in association with other congenital anomalies.This case report aimed to describe a radiographically confirmed case of syndactyly in a piglet.

Case description: A 17-day-old 6.2 kg piglet showed syndactyly in all four limbs. Although this anomaly did not affect the patient's daily activities, it was a congenital malformation of clinical and zootechnical relevance. A complete blood count, morphometric measurements, and limb radiographs were performed. Radiographs revealed a fusion of phalangeal bones in the forelimbs and an accessory phalangeal element located axially between the principal digits in the hindlimbs. The complete blood count revealed mild leukocytosis.

Conclusion: Syndactyly occurs during embryonic development when the phalanges do not separate. Its severity can vary from a simple skin union to complete bone fusion. Syndactyly etiology is multifactorial and involves genetic and environmental factors.

猪的并指。

背景：并指，又称骡足，是最常见的肢体畸形之一。在猪中，并指畸形与遗传或环境因素有关，是一种孤立的缺陷或与其他先天性异常有关。本病例报告旨在描述一个放射学证实的猪并指畸形病例。病例描述：17日龄6.2公斤仔猪，四肢并指。虽然这种异常不影响患者的日常活动，但它是一种与临床和动物技术相关的先天性畸形。进行了全血细胞计数、形态测量和肢体x线片检查。x线片显示前肢指骨融合，后肢指骨间轴向有副指骨。全血细胞计数显示轻度白细胞增多。结论：在胚胎发育阶段，指骨未分离时发生并指畸形。其严重程度可以从简单的皮肤愈合到完全的骨融合。并指畸形的病因是多因素的，涉及遗传和环境因素。
