RESUMEN
Objetivo. Valorar los resultados clínicos y radiológicos de un cotilo monobloque de tantalio con un seguimiento medio de 12 años. Material y método. Se siguieron prospectivamente 23 prótesis de cadera en 23 pacientes. Los diagnósticos más frecuentes fueron coxartrosis primaria (9 casos) y necrosis avascular (7 casos). Los resultados clínicos fueron valorados con la escala de Merle D¿Aubigne-Postel. Se midieron la orientación de los componentes, la integración de los cotilos y la presencia de hiatos postoperatorios o aparición de líneas radiolúcidas. El desgaste del polietileno fue medido con el método de Kim. Resultados. El seguimiento medio de la serie fue de 12 años. Todos los implantes se encontraban osteointegrados al final del seguimiento. Los valores medios de dolor, capacidad de deambulación y movilidad en la escala de Merle D¿Aubigne-Postel fueron 5,4, 5,2 y 4,4 respectivamente al final del seguimiento. En un cotilo un hiato postoperatorio no se había rellenado y 4 implantes tenían líneas radiolúcidas no progresivas en la parte de la zona 1 de DeLee. Conclusiones. Los cotilos monobloque de tantalio presentan una excelente supervivencia con seguimientos superiores a diez años en cirugía primaria de cadera (AU)
ABSTRACT
Objective. To evaluate the clinical and radiological results of a tantalum acetabular monoblock with a mean follow up of 12 years. Material method. A prospective follow up was performed on 23 hip replacements in 23 patients. The most frequent diagnosis was primary coxarthrosis (9 cases) and avascular necrosis (7 cases). The clinical results were assessed using the Merle D¿Aubigne-Postel scale. The orientation of the components, the integration of the acetabula, and the presence of post-operative hiatus, or the appearance of radiolucent lines were evaluated. The polyethylene wear was measured using the Kim method. Results. The mean follow-up of the series was 12 years. All the implants were osseointegrated at the end of follow-up. The mean values of, pain, ability in walking, and mobility on the Merle D¿Aubigne-Postel scale were 5.4, 5.2 and 4.4, respectively, at the end of follow-up. A postoperative hiatus had not been filled in one acetabulum, and 4 implants had non-progressive radiolucent lines in the area of the DeLee zone 1. Conclusions. Tantalum acetabular monoblocks have an excellent survival with follow-ups longer than ten years in primary hip surgery (AU)
