The central portion of the HammerTube™ implant is uncoated allowing it to be cut at the joint space to facilitate removal. In order to streamline removal, dedicated easyouts and trephines are included in the removal system. Finally, the implant comes sterile packaged in four configurations to address varying patient anatomy and is intended to press fit on either side of the joint space following drilling.
