What is it indicated for?

The Cadence Ankle PSI System is intended to be used as patient specific surgical planning and

instrumentation to assist in the positioning of total ankle replacement components intraoperatively,

Nephew's Cadence Total Ankle System and its cleared indications for use, provided that anatomic

landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging

CT scans.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
