Efeito do ácido zoledrônico e do alendronato no edema ósseo e dor na osteonecrose espontânea do joelho: Um novo paradigma no manejo[*]
Article in several languages: português | EnglishResumo
Objetivo Determinar o efeito do tratamento combinado de ácido zoledrônico e alendronato no edema ósseo e na dor no joelho em casos de osteonecrose espontânea do joelho. A experiência dos autores com este tratamento é relatada.
Métodos Série de casos retrospectiva, incluindo 11 pacientes com osteonecrose espontânea do joelho confirmada por ressonância magnética. Os pacientes foram tratados com uma dose intravenosa única de 5 mg de ácido zoledrônico combinada com 35 mg de alendronato oral, 2 vezes por semana, por 16 semanas. Os escores da escala visual analógica foram aferidos antes do começo do tratamento, em 8 semanas e em 16 semanas de acompanhamento. O tamanho do edema da medula óssea adjacente à lesão foi medido em imagens de ressonância magnética coronal ponderadas em T2 no início do tratamento e em 16 semanas.
Resultados O escore médio da escala visual analógica em 0 semanas foi de 7,72, contra 0,81 em 16 semanas de tratamento, uma diferença estatisticamente significativa (p = 0,03). O envolvimento médio da medula óssea em 0 semanas foi de 80%, e foi reduzido para 11,81% em 16 semanas de tratamento, uma diferença também estatisticamente significativa (p = 0,03).
Conclusão Os dados mostram que a terapia combinada proporciona alívio da dor inicial e redução do edema ósseo, sendo segura, eficaz e bem tolerada em uma enfermidade dolorosa como a osteonecrose espontânea do joelho.
