Revision total hip arthroplasty in patients with a nonsupportive superior acetabulum often requires secondary augmentation beyond a hemispherical cup to achieve reliable fixation. Treatment options include using a higher hip center, jumbo cup, custom triflange implant, cages, or filling the superior defect with a bilobed implant, structural allograft, or metal augments. We previously reported a cohort of 31 patients treated with porous-coated hemispherical cups and distal femoral allograft for Paprosky type IIIA acetabular defects.


The use of distal femoral allograft can be considered in young patients with type IIIA acetabular defects that could benefit from restoration of bone stock.

Revisión artroplastia total de cadera en pacientes con falta de apoyo en el acetabulo superior a menudo requiere el aumento secundario más allá de una taza semiesférica para lograr una fijación fiable. Las opciones de tratamiento incluyen el uso de un centro superior de la cadera, la taza jumbo, triflange implante personalizado, jaulas, o rellenando el defecto superior con un implante bilobulado, aloinjerto estructural, o aumenta de metal. Hemos informado anteriormente de una cohorte de 31 pacientes tratados con copas semiesféricas con recubrimiento poroso y aloinjerto femoral distal de tipo IIIA Paprosky defectos acetabulares.

El uso de aloinjerto femoral distal puede ser considerado en pacientes jóvenes con defectos acetabulares tipo IIIA  que podrían beneficiarse de la restauración de la masa ósea.
