【 摘 要 】

Category:Ankle ArthritisIntroduction/Purpose:Ten-year Total Ankle Replacement (TAR) survivorship improved from 80 to 90%. But periprosthetic osteolysis associated with implant subsidence remains the main problem, with difficult revision surgery by arthrodesis; bone defect requiring massive graft. We proposed an original approach using porous tantalum as spacer to fill the defect and reinforce arthrodesis-reconstructionMethods:From October 2013 to September 2015, eleven patients underwent TAR revision (7 AES TM, 2 Hintegra TM, 1 Salto TM, 1 Albatros TM) by ten TTC arthrodesis and one ankle arthrodesis using tantalum (with Zimmer Trabecular Metal Ankle Interpositional SpacerTM introduced in July 2013). All patients were followed up prospectively clinically and radiologically (X-rays and CT scan at 4-6 months, and 1 year); and a bone scan with SPECT- CT if residual pain at one year. Mean age was 53.2 yrs [37-82yrs] at TAR, 66.6 yrs [41–90 yrs] at revision-arthrodesis, with a mean interval of 7.2 yrs [2-12yrs...
