Avaliação radiográfica de cães com displasia coxofemoral tratados pela sinfisiodese púbica

Abstract

The radiographic findings in hip dysplastic or potentially hip dysplastic dogs treated by the pubic symphysiodesis were evaluated using 14 dogs - six males and eight females -, aging from four to six-month- old. After physical examination, the hip joint was evaluated by radiographic examination according to pattern established by the Colegio Brasileiro de Radiologia Veterinária. In addition, three dogs were evaluated by PennHIP method. According to medical history, nine (64%) dogs were admitted due to signs of locomotor difficulty in pelvic limbs, especially characterized by uni or bilateral lameness and stiffness on rising. Five (36%) dogs had no clinical signs. Radiographic examination was performed in four (29%) dogs as prevention. The most evident physical sign was pain on manipulation of the hip with Ortolani-positive in two (14%) dogs. Except for one dog that presented infection signs in the skin suture, no other postoperative complication was observed. The follow-up radiographic examination revealed progression of the degenerative articular changes in six (43%) dogs, and eight (54%) had no progression. In conclusion, the dogs treated by pubic symphysiodesis did not have improvement of the preoperative radiographic signs.
