Ectrodactilia em cão: relato de caso

Abstract

RESUMODescreve-se um caso de ectrodactilia em um cão, sem raça definida e dois meses de idade. No exame clínico e radiográfico, foi verificada a separação óssea e de tecidos moles entre o segundo e o terceiro dígitos, estendendo-se proximalmente até a região distal do rádio e da ulna, e luxação do cotovelo ipsilateral. O animal foi submetido a procedimento cirúrgico para redução da luxação do cotovelo e reaproximação óssea e dos tecidos moles. Após 16 meses da cirurgia, o animal apresentava uso parcial do membro.Palavras-chave: cão, ectrodactilia, malformação congênita, luxação de cotovelo ABSTRACT A case of ectrodactyly is described in a 2-month-old male mixed Terrier dog. The defect was a complete osseous and soft tissue separation extending from between digits 2 and 3 proximally to the level of the radius and ulna. Radiography revealed elbow luxation. Treatment consisted of surgical reduction of elbow luxation and soft tissue reconstruction. Sixteen months after surgery, the dog was intermittent nonweight-bearing lameness.

Congenital deformity of the paw in a captive tiger: case report

“…However, in domestic cats a mode of inheritance due to a heterozygous gene with variable expression has been demonstrated [14]. Except for hemivertebra [15], other detectable congenital abnormalities have not been found in most of the reported cases of ectrodactyly in dogs and cats [4-10,12,13]. In the present case, the tiger was the first of his species to show such a deformity, and no other abnormality was observed.…”

“…In case of minor lesions of ectrodactyly that do not affect limb function no treatment is required; however, reconstruction is necessary in severe cases [5,7-9,12]. In the present case the malposition of the digit was inducing lameness, because of the constant trauma of the digit on the ground as confirmed by the worn nail and luxation between the metacarpal bone and proximal phalanx.…”

“…Axial separation between metacarpal bones; abnormal carpal, metacarpal and phalangeal bones; syndactyly; and separation between the radius and ulna are some of the radiological features reported [5,7,10,14]. In addition, elbow luxation has been associated with some ectrodactyly cases in dogs [5,7,10,12]. Clinical signs of deformity and lameness may progress with age, even if the malformation has been present since birth [3,7].…”

Ectrodactilia en un Beagle: manejo quirúrgico

“…Si bien la ED puede ser diagnosticada durante el proceso del examen clínico, es imprescindible realizar el estudio por imágenes del miembro afectado. Las radiografías deben tomarse perpendiculares entre sí y deben incluir todo el miembro anterior, ya que son muy frecuentes las complicaciones ortopédicas en hombro, codo y antebrazo (Ferreira et al, 2007).…”

“…La ED se caracteriza clínicamente por la presencia de un tejido blando anormal, que produce una separación o hendidura desde el extremo proximal de los dedos hacia los huesos metacarpianos. Esta separación puede extenderse incluso hasta la articulación antebraquiocarpiana (Ferreira et al, 2007). La ED se ha reportado en varias especies de mamíferos, incluyendo el humano (Elliott et al, 2006).…”
