Langtidsoppfølging av Integra® Cadence™ Total ankelsystem i primær ankelleddserstatning
17. juni 2026 oppdatert av: Smith & Nephew, Inc.
Denne studien vil evaluere de langsiktige ytelses- og sikkerhetsdataene for Cadence™ Total Ankel System (CTAS) når det brukes til primær artroplastikk hos pasienter med primær artritt (f.
degenerativ sykdom), sekundær leddgikt (f.eks.
posttraumatisk, avaskulær nekrose, hvis minst 2/3 av talus er bevart), og systemisk artritt i ankelen (f.eks.
revmatoid artritt, hemokromatose)
