This retrospective study from two tertiary sarcoma centers compares outcomes of 78 cemented Harrington reconstructions versus 37 porous tantalum acetabular reconstructions performed for periacetabular metastatic disease between 2002 and 2015, examining reoperation rates, implant loosening, functional outcomes, and operative time.
When operating on periacetabular metastatic disease in a patient with reasonable life expectancy, porous tantalum reconstruction offers lower reoperation risk and durable fixation even with local disease progression — reserve Harrington technique for cases with complete ilial discontinuity or sacropelvic instability where tantalum osseointegration cannot be achieved.
