“…A great variety of surgical techniques are described for canine HD treatment; among them are pectineal myectomy (Wallace & Olmstead 1995), intertrochanteric femoral osteotomy (Wallace & Omstead 1995, Piermattei & Flo 1997, total prosthesis of the hip joint (Perot 1984, Wallace & Omstead 1995, Minto et al 2008, arthroplastic excision of the femoral head and neck (Iamaguti 1981, Piermattei & Flo 1997, extracapsular acetabuloplasty (Iamaguti et al 1996, Ferreira et al 2007), femoral head ligament restoration using fascia lata grafts (Brandão 1999), and acetabuloplasty with femoral head ligament reconstruction (Bergamo 2001).…”

RESUMO.-[Aprofundamento do acetábulo no tratamento de displasia coxofemoral grave em cães.] Uma técnica para restituir a anatomia acetabular com aprofundamento da cavidade acetabular e reconstrução do ligamento da cabeça do fêmur e da cápsula articular, foi testada em nove cães, de raças de grande porte, portadores de displasia coxofemoral grave com subluxação acentuada ou luxação. O procedimento cirúrgico foi constituído de duas fases. Inicialmente, foi realizada a pectineotomia bilateral em todos os cães. A segunda intervenção nos mesmos cães incluiu abordagem e aprofundamento do acetábulo, reconstrução do ligamento da cabeça do fêmur e da cápsula. Em geral, 30 dias após a cirurgia, os cães apoiavam o membro operado para se locomover. Com exceção de dois cães, todos os outros recuperaram a função locomotora do membro pélvico dentro de 60-90 dias. É concluído que a técnica de acetabuloplastia é uma boa alternativa para o tratamento da displasia coxofemoral grave.TERMOS DE INDEXAÇÃO: Doenças de cães, cirurgia, displasia coxofemoral, acetabuloplastia. INTRODUCTIONHip dysplasia (HD) is the abnormal development of the hip joint (Fossum et al. 2002, Olmstead 2003. It can be bilateral and manifests as varying degrees of looseness of soft tissues adjacent to femoral head, acetabulum instability and malformation, and degenerative joint disease (DJD) (Brinker et al. 1999). It's a quantitative polygenic disease, influenced by non-genetic factors and characterized by well-defined phenotypic classes which includes normal and affected individuals with varying degrees of severity. Thus, some dogs may present HD-related genes without presenting the disease (Dal-Farra & Kilp 1998).HD generally manifests as painful, gradually incapacitating condition, mainly affecting large and giant canine breeds (Piermattei & Flo 1997 Júnior s/n, Botucatu, SP 18618-000, Brazil. E-mail: raquelsartor@yahoo.com.br A technique to restore acetabular anatomy by deepening the acetabular cavity and reconstructing the femoral head ligament and the joint capsule was tested on nine large breed dogs with severe hip dysplasia and acute subdislocation or dislocation. The technique consisted of two phases. First, all dogs were submitted to bilateral pectinotomy. In a second surgical intervention on the same dogs the acetabulum was approached and deepened, and the femoral head ligament and the joint capsule were reconstructed. In general, within 30 days of the surgery dogs could stand on the operated member to walk. Except for two dogs, all the others recovered pelvic member locomotive ability within 60-90 days after surgery. It is concluded that acetabuloplasty is a good alternative for treatment of severe canine hip dysplasia.INDEX TERMS: Diseases of dogs, surgery, hip dysplasia, acetabuloplasty.

BackgroundThis prospective experimental study evaluated the surgical procedure and results of modular hybrid total hip arthroplasty in dogs.MethodsTen skeletally mature healthy mongrel dogs with weights varying between 19 and 27 kg were used. Cemented modular femoral stems and uncemented porous-coated acetabular cups were employed. Clinical and radiographic evaluations were performed before surgery and at 30, 60, 90, 120, 180 and 360 days post-operation.ResultsExcellent weight bearing was noticed in the operated limb in seven dogs. Dislocation followed by loosening of the prosthesis was noticed in two dogs, which were therefore properly treated with a femoral head osteotomy. Femoral fracture occurred in one dog, which was promptly treated with full implant removal and femoral osteosynthesis.ConclusionsThe canine modular hybrid total hip arthroplasty provided excellent functionality of the operated limb.
