“…However, in this case, the questions above did not befall according her. Although there are various suspicion about the causes of hemimelia, some authors state that its etiology is unknown (Macrí et al, 2009;Pisoni et al, 2012;Peres et al, 2013;Macrí et al, 2014), including in humans (Riaz et al, 2016). In this case, the presence of consanguinity, as reported by the owner, can be considered as a possible cause of dysostosis, in accordance with Prats (2005).…”

“…The denominations of malformations are rarely used in veterinary science, by the reason that there is not a uniform and accurate terminology for several species (Macrí et al, 2014). However, the congenital classification disorders in humans, described by Kay et al (1974) has been used to classify animal disostosis, as was done by Johnson, Kenneth, and Watson (2014).…”

-Hemimelia is a rare congenital anomaly, characterized by the absence of a part or the whole distal segment of a body member. It is usually unilateral and is classified according to the affected bone segments. In the transverse terminal hemimelia, there is the absence of the whole distal part of a body member, what is defined as congenital amputation. Several studies about cats and dogs concluded that radial hemimelia is the most usual. However, other types of this anomaly are rarely observed in dogs. Therefore, the aim of this study is to report a case of transverse terminal humeral bilateral hemimelia in a mixed-breed dog. In the physical exam was observed a bilateral malformation of the thoracic members. The radiographs revealed the presence of a well-developed scapula, humeral vestiges and the absence of other appendicular segments on the right and left antimeres, what made the hemimelia diagnosis possible. Consanguinity was the probable cause of the anomaly. Because of the scarcity of scientific reports about this pathology in dogs, further studies are needed to investigate the here observed.Keywords: canids; congenital amputation; bones.RESUMO -Hemimelia é uma rara anomalia congênita caracterizada pela ausência de parte ou todo o segmento distal de um membro, de ocorrência geralmente unilateral e classificada de acordo com os segmentos ósseos afetados. Na hemimelia transversa terminal toda a porção distal de um membro está ausente, sendo definida como amputação congênita. Diversos estudos em cães e gatos reportam a hemimelia radial, sendo esta a forma mais frequente. Não obstante, raras são as abordagens em cães acerca das demais apresentações da hemimelia. Assim, este estudo objetiva relatar um caso de hemimelia transversa terminal umeral bilateral em um cão mestiço. No exame físico, observou-se má formação dos membros torácicos. As imagens radiográficas revelaram nos antímeros direito e esquerdo a presença de escápula desenvolvida, resquícios umerais e ausência dos demais segmentos apendiculares, permitindo assim o diagnóstico de hemimelia. Como causa provável constou apenas o fator de consanguinidade. Devido escassez de abordagens científicas acerca deste tipo de patologia em cães, demais estudos são necessários para investigar o aqui observado. Palavras-

ABSTRACT:This article reports a case of a congenital unilateral forelimb defect in a two-month-old male puppy with clinical and radiographic findings. Congenital deformities are structural or functional congenital defects arising from errors during development, and they can affect an isolated portion of the body, the complete body or parts of several systems of the body. The congenital absence of a portion of the proximal epiphysis of the radius is an extremely rare condition in human and animal species. Although similar congenital limb deformities have been infrequently reported in dogs, the present case is, to the best of the authors' knowledge, the first report of this type of partial forelimb paraxial radial hemimelia in a puppy, and it represents an addition to the scant literature on this topic.
