Clinical and radiographic evaluation of double pelvic osteotomy to treat canine hip dysplasia
The purpose of this study was to describe our initial experience with double pelvic osteotomy (DPO) in young dogs affected by hip dysplasia (HD) and to report their postoperative outcome. Seven dogs (four females and three males) were included in our study with mean age 8.3 (±1.7) months, and mean b...

Zusammenfassung: | The purpose of this study was to describe our initial experience with double pelvic osteotomy (DPO) in young dogs affected by hip dysplasia (HD) and to report their postoperative outcome. Seven dogs (four females and three males) were included in our study with mean age 8.3 (±1.7) months, and mean body weight 29.5 (±7.4)Kg. Breeds involved were: Rottweiler (n = 1), Labrador Retriever (n = 3), Golden Retriever (n = 1), Great Dane (n=1) and São Miguel Cattle Dog (n = 1). The most common history complaints were: pelvic limb lameness and pain at hip extension and hip abduction. All surgical procedures consisted of osteotomy of the ilium and pubis, acetabular ventroversion and iliac stabilization with a customized bone plate with seven screws, four screws placed at the cranial fragment and the remaining three in the caudal aspect. Average surgical time was 65.8 (±10.4) minutes and median follow-up assessment was 68 (±15) days. Fracture healing was observed within mean period of 26.3 (±8.9) days. Six patients (86%) had satisfactory outcome and one patient didn’t improve after surgery and had to undergo a total hip replacement. Our results showed that DPO is an effective treatment for HD due to the preservation of pelvic geometry and low postoperative morbidity. Since it is a recent technique, further studies are recommended.
RESUMO: O objetivo do estudo é a descrição da osteotomia dupla da pelve (ODP) em pacientes com displasia coxofemoral (DCF) e relatar a evolução pós-operatória. As raças acometidas foram: Rottweiler (n=1), Labrador (n=3), Golden Retriver (n=1), Dogue alemão (n=1) e Fila de São Miguel (n=1). O total foi de sete animais, sendo três machos e quatro fêmeas; a média de idade e peso dos cães foi de 8,3±1,7 meses e 29,5±7,4Kg, respectivamente. As queixas iniciais mais comuns antes da cirurgia foram: claudicação em membro pélvico e dor à extensão e abdução do quadril. A cirurgia constou em realizar a osteotomia do ílio e púbis, rotacão axial do acetábulo sobre a cabeça do fêmur e osteossíntese do ílio com a utilização de placa fixada com sete parafusos, quatro destes no segmento cranial e três no segmento caudal. Após a cirurgia um animal não apresentou melhora do quadro, caracterizado por agravamento da subluxação coxofemoral, sendo submetido à prótese total de quadril. O tempo médio de cirurgia foi de 65,8±10,4 minutos e o período de acompanhamento médio pós operatório foi de 68,0±15,0dias, visibilizando a reação osteoproliferativa no foco de osteo |
