With the aid of a stabilizing shoe made of cartilage a total prosthesis can be positioned centrally and retained on the stapes footplate. In this way the surgeon counteracts a potential postoperative dislocation.

KURZ developed the Cartilage Punch in an effort to reproduce a more consistent option for stabilizing of total prostheses. The instrument enables the surgeon to make small oval cartilage slices intraoperatively, swiftly, and in a single step. The center perforation is intended for KURZ Total Prostheses with a circular hollow stem.
