Langtidsopfølgning af Integra® Cadence™ Total Ankel System i primær ankelledserstatning

17. juni 2026 opdateret af: Smith & Nephew, Inc.
Denne undersøgelse vil evaluere de langsigtede præstations- og sikkerhedsdata for Cadence™ Total Ankel System (CTAS), når det bruges til primær artroplastik hos patienter med primær arthritis (f. degenerativ sygdom), sekundær arthritis (f.eks. posttraumatisk, avaskulær nekrose, hvis mindst 2/3 af talus er bevaret), og systemisk arthritis i anklen (f.eks. reumatoid arthritis, hæmokromatose)

Tidsramme
Implant Survivorship at 5 Years and 10 Years
Tidsramme: 5 years and 10 years

  2. device tilting = present, OR
  3. device subsidence (tibial OR talar) = >4mm, OR
  4. device migration (tibial OR talar) = >4mm
