Instrument for prosthesis stabilization.Kurz Medical, Inc., offers its cartilage punch, a simplified and standardized solution for optimal stabilization of Kurz AERIAL total prostheses Prostheses A synthetic object that resembles a missing anatomical part.

The potential risk of postoperative dislocation exists, however, for all total reconstruction procedures. The Kurz cartilage punch produces a cartilage mounting with a central perforation, which stabilizes the prosthesis. The cartilage plate is placed in the oval niche in such a way that the opening is situated over the center of the footplate, and the opening exactly fits the stem end of a Kurz AERIAL total prosthesis. Moreover, the centered position on the footplate seems to be the ideal position for improved hearing results. Early experiments showed that such a cartilage fixation in the oval niche will not significantly impede the vibration of the stabilized prosthesis. A subsequent clinical trial in 22 patients (in press) showed that using the cartilage plate for stabilization improved average hearing results, and no dislocation was observed.
