“…The affected limb(s) are shortened with a varus deformity and are not functional or gaiting (Jonson, 1995). In our patient, the clinical signs were also similar with the previous reports of hemimelia in dogs (Lallo et al, 2001;Rahal et al, 2005), cats (Lewis and Van Sickle, 1970), goats (Corbera et al, 2002), minks (Rantanen and Hegreberg, 1982), and humans (Mo and Manske, 2004). The etiology of radial hemimelia is considered to be genetical, environmental or a combination of both factors.…”

A 9-month-old 10 kg intact male crossbred dog was admitted to The Animal Medical Centre, Chonbuk National University with congenitally malformed right forelimb. Physical exanimation of the limb showed varus deviation of the forepaw and flexion contracture of the interphalangeal joints. The survey radiographs revealed complete absence of the radius, poor congruency of the humeroulnar joint and 90° varus deviation of the ulnocarpal joint. A preaxial longitudinal intercalary radial hemimelia was diagnosed and the dog underwent 3 surgeries for correction of the deformity. During the first surgery, olecranon osteotomy and arthrodesis of the elbow were performed. Three months later, a second surgery was done to perform carpal panarthrodesis using bone plate and screws which was unsuccessful. Two weeks after, with a third surgery carpal arthrodesis was performed using acrylic frame, the distal portion of limb was straightened and the residual deviation of the forepaw was corrected. The surgical corrections resulted in satisfactory use of the limb and a better quality of life.

“…Radial hemimelia is a congenital abnormality characterized by the partial or complete absence of the radius (Corbera et al, 2002;Towle and Breur, 2004). If all or part of the middle bones of a limb are absent, with the proximal and distal portions being present, the hemimelia is called intercalary.…”

“…A forma mais comum de hemimelia em cães é a radial, caracterizada pela ausência parcial ou completa do rádio (CORBERA et al, 2002;TOWLE;BREUR, 2004), que provoca deformidade angular do membro afetado, acarretando severas limitações funcionais (MENDES; RAUSCH; CARAPETO, 2004).…”

Hemimelia bilateral de rádio em canino – relato de caso

ResumoHemimelia ou agenesia é uma alteração morfológica congênita que pode acometer o esqueleto apendicular. Esta anomalia rara consiste na ausência total ou parcial de um ou mais ossos pareados. Pode se apresentar de forma uni ou bilateral, sendo a unilateral mais frequente. Em cães, a forma mais comum de hemimelia é a radial, que provoca deformidade do membro afetado e severas limitações funcionais. Foi atendido no Hospital Veterinário da Universidade Federal de Mato Grosso (HOVET/UFMT), um canino, fêmea, sem raça definida, com 30 dias de idade, apresentando deformidade nos membros torácicos desde o nascimento, claudicação e dificuldade de apoio. Após o completo desenvolvimento ósseo o animal retornou para uma reavaliação e estabelecimento do tratamento adequado. O exame radiográfico revelou agenesia bilateral dos rádios, angulação das ulnas no sentido cranial, fusão dos ossos cárpicos das fileiras proximal e distal, luxação escapuloumeral bilateral e presença de estrutura óssea com limites bem definidos e formato retangular articulada com as escápulas. Devido à boa qualidade de vida do animal e ao reservado prognóstico de uma intervenção cirúrgica, optou-se pelo tratamento conservativo, sendo recomendada a castração e ambiente de piso macio. Palavras-chave: Canino, agenesia, membro, ausência AbstractHemimelia or agenesis is a congenital morphological change that may affect the appendicular skeleton. This rare anomaly is the total or partial absence of one or more bones matched. It may present unilaterally or bilaterally, with the most frequent unilateral. In dogs, the most common form of the radial hemimelia is that causes deformity of the affected limb and severe functional limitations. Was Veterinary Hospital of the Federal University of Mato Grosso (HOVET/UFMT), a canine, female mongrel, with 30 days of age, presenting deformity in thoracic limbs since birth, observed signs of lameness and difficulty support. After complete bone development the animal returned for re-evaluation and establishment of appropriate treatment. On radiographic examination, there was bilateral agenesis of radios, angulation of the ulnar cranially, fusion of carpal bones proximal and distal to the ranks, bilateral scapulohumeral dislocation and the presence of a bone structure with well-defined boundaries and rectangular articulated with the scapula. Due to good quality of life of the animal and reserved prognosis of surgery, we opted for conservation of members. The owner was recommended to keep the animal in an environment with soft ground and castration.

“…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). Despite the fact that there is little study concerning the consanguinity as a cause of these changes in dogs, some cases have already been observed in other species, as in caprines and equines (Corbera et al, 2002;Marchiori et al, 2014). Indeed, Marchiori et al (2014) describes a bilateral amelia of the forelimbs in an Arabian foal, daughter of parents with 25% of consanguinity.…”

-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-
