RetroFusion™ PIP Joint Arthrodesis Implant

The RetroFusion screw is a headless implant designed for PIP arthrodesis that provides compression and strength across the joint. The implant’s proximal and distal threads are arranged in opposite directions to pull the joint together when the implant is inserted.

• Opposing threads on implant pull the joint together for maximum compression of the PIP joint
• Better fixation of the joint since actual compression is achieved
• Simple technique that also allows for flexed fusions and no violation of the DIP joint
