Ascension PyroSphere

Introduction

The PyroSphere prosthesis (PCS) is made of PyroCarbon, a material with high degree of biocompatibility and resistance against wear and fatigue. The spherical PCS prosthesis is designed for patients who have arthritis affecting the CMC joint and is available in 5 different sizes. The prosthesis could be used when the cartilage is damaged on both sides of the CMC joint.

Indications

The Ascension® PyroSphere should only be used in patients who have arthritis affecting the carpal metacarpal joint at the base of the
thumb. It is not designed for use in patients who have significant scaphotrapezial trapezoidal arthritis.
