Mini TightRope® CMC Technique
The Mini TightRope® CMC Technique provides a unique means to suspend the thumb metacarpal after partial or complete trapezial resection for treatment of CMC arthritis, thumb CMC instability and in revision cases. The Mini TightRope implant supports and maintains the thumb and index metacarpals in the proper relationship, while allowing for capsular healing and hematoma and scar tissue formation in the trapezial space. The construct consists of 2 strands of #2 FiberWire® suture, which are fixed with 2 oblong stainless steel buttons for cortical fixation. The trapezial space may be left empty or filled with an autograft, allograft, or artificial spacer.
