ABSTRACT

OBJETIVO: Verificar o remodelamento acetabular através dos métodos de Sotelo-Garza e Charnley e da Linha de Kõhler ou linha ílio-isquiática, de pacientes submetidos à artroplastia total do quadril com acetábulo rosqueado tipo CO-10. RESULTADOS: Com relação à classificação de Sotelo-Garza e Charnley, tínhamos no pré-operatório 6 pacientes no grupo I (leve) e 14 pacientes no grupo II (moderada), não classificando nenhum paciente com protrusão acetabular grave ou maior de 15 mm. No pós-operatório, o grupo I passou a ter 17 pacientes com somente 3 no grupo II, mantendo-se o grupo III sem nenhum paciente classificado. O paciente que apresentou o maior remodelamento acetabular foi o de maior seguimento da série (10 anos), diminuindo 9 mm pelo método LK e 5 mm pelo método de Sotelo-Garza e Charnley. MATERIAIS E MÉTODOS: Foram analisados de maneira retrospectiva e descritos 20 casos de pacientes com Otopelve tratados de 1996 a 2005, submetidos à artroplastia total do quadril com acetábulo rosqueado tipo CO-10. Verificamos o remodelamento acetabular através dos métodos de Sotelo-Garza e Charnley e da Linha de Kõhler ou linha ílio-isquiática. CONCLUSÃO: Verificamos ser significante o remodelamento do acetábulo com o método de tratamento proposto, o que fala a favor do uso de próteses não cimentadas de apoio acetabular equatorial para tratamento da Otopelve.


OBJECTIVE: To check the acetabular remodeling through the methods described by Sotelo-Garza and Charnley, as well as the Kõhler Line or ilio-ischiatic line on patients submitted to total hip arthroplasty with threaded cup CO-10. RESULTS: Concerning the classification by Sotelo-Garza and Charnley, preoperatively, we had 6 patients on group I (mild) and 14 patients on group II (moderate), not classifying any patient with severe acetabular protrusion or above 15 mm. Postoperatively, group I was constituted of 17 patients, and only 3 on group II, with group III remaining with no patients included. The patient who presented the best acetabular remodeling was the one with the longest follow-up time (10 years), reducing 9 mm by the LK method and 5 mm by Sotelo-Garza and Charnley's method. MATERIALS AND METHODS: 20 cases of Otto pelvis patients treated between 1996 and 2005 submitted to total hip arthroplasty with threaded cup CO-10 were retrospectively described. We checked for acetabular remodeling through the methods by Sotelo-Garza and Charnley and Kõhler or ilio-ischiatic line. CONCLUSION: We found a significant acetabular remodeling with the proposed treatment approach, which advocates the use of non-cemented prosthesis for equatorial acetabular support for treating Otto pelvis.
