A displasia coxofemoral caracteriza-se por incongruência da cabeça do fêmur ao articular-se com o acetábulo, acarretando em frouxidão e instabilidade articular. Este trabalho, tem como objetivo relatar o caso de uma canina diagnosticada com displasia coxofemoral bilateral. Após atendimento inicial, foi realizado exame radiográfico, o qual evidenciou alterações características de displasia coxofemoral, a partir de então optou-se pela intervenção cirúrgica inicial usando a técnica de colocefalectomia, no membro esquerdo, o qual apresentava-se mais acometido radiograficamente. A causa etiológica não foi determinada, porém acredita-se que por ser um animal de grande porte e de rápido crescimento, houve disparidade da musculatura adjacente. O exame radiográfico mostrouse eficaz, bem como o teste de Ortolani, como meios diagnósticos. O tratamento cirúrgico permitiu alívio da dor e função razoável da articulação, mas complicações a longo prazo não podem ser descartadas.Palavras chave: articulação coxofemoral, artroplastia, cães, osteotomia da cabeça do fêmur Use of the colocephalectomy technique in the treatment of hip dysplasia in canine: Case reportABSTRACT. Coxofemoral dysplasia is characterized by incongruence of the head of the femur when articulating with the acetabulum, leading to laxity and joint instability. This study aims to report the case of a canine diagnosed with bilateral hip dysplasia. After initial care, a radiographic examination was performed, which revealed characteristic changes of the hip, and the initial surgical intervention was performed using the colocephalectomy technique in the left limb, which was more affected by radiographs. The etiologic cause was not determined, but it is believed that being a large animal and fast growing, there was disparity of the adjacent musculature. The radiographic examination proved to be effective, as well as the Ortolani test, as diagnostic means. Surgical treatment allowed for pain relief and reasonable joint function, but long-term complications can not be ruled out.
This work was carried out in collaboration between both authors. Author RS designed the study, took the images, and wrote the discussion. Author NF managed the literature searches, and wrote the case presentation. Both authors read and approved the final manuscript.
