Ectrodactyly is a rare developmental anomaly of the distal part of the forelimb. It is characterized by the presence of an abnormal longitudinal soft tissue and osseous separation or cleft between the digits and the metacarpal bones. It can be associated with hypoplasia, aplasia and malformation of one or more bones of the antebrachium, carpus, metacarpus and digits. Unilateral ectrodactyly and moderate lameness were diagnosed in a young female dog. The dog was treated surgically with reconstruction of soft tissues and stabilization of the metacarpal bones by two nylon cerclage sutures. After three years a mild residual lameness was present. Radiographic signs of synostosis between the metacarpal bones II, III and IV with presence of a cleft between carpal bones II and III were observed.
缺指（趾）畸形是前肢远端罕见的发育异常。其特征是在手指与掌骨之间存在异常的纵向软组织和骨分离或裂隙。它可能与前臂、腕骨、掌骨和手指的一根或多根骨头发育不全、发育不全和畸形有关。在一只年轻雌性犬中诊断出单侧缺指（趾）畸形和中度跛行。对该犬进行了手术治疗，通过两根尼龙环扎缝线重建软组织并稳定掌骨。三年后仍存在轻度残留跛行。观察到第二、三、四掌骨之间有骨融合的放射学迹象，第二和第三腕骨之间有裂隙。
