A osteotomia dupla de pelve no controle da doença

Abstract

Hip dysplasia is a congenital and hereditary developmental joint disorder characterized by subluxation of the hip joint in dogs and other species. It can be identified in young dogs, but is commonly seen in older dogs due to consequent joint degeneration. It often occurs in dogs over 11 kg and its cause involves environmental and genetic factors. However, hereditary factors have been shown to be determinant for the occurrence of this disease. The present work presents a clinical case of hip dysplasia in a six-month-old Golden Retriever bitch that presented lameness in the left pelvic limb. The diagnosis was made through clinical and radiographic examination. On physical examination, the animal presented pain on extension and flexion of the coxofemoral joint and bilateral positivity in the performance of the Ortolani maneuver. The radiographic examination was performed with a PennHip™ distractor for positioning that allows determining the distraction index and confirming the diagnosis. The treatment chosen was double pelvic osteotomy, indicated for young animals without signs of joint degeneration, which improves the postoperative prognosis. After surgery, the patient had a quick and uneventful recovery. Early diagnosis, the cooperation of tutors and the correct execution of the technique are crucial for the successful treatment of hip dysplasia in young animals. Double pelvis osteotomy is one of the surgeries indicated to control dysplasia with a view to reducing the progression of the disease and maintaining the quality of life of dogs in adulthood.
