Mini TightRope® CMC Technique


The Mini TightRope provides a unique method for stabilization of the thumb metacarpal following trapezial resection or removal for the treatment of CMC arthritis. The Mini TightRope can also be used as an adjunct and stabilizer in CMC instability and in the case of revision with proximal migration after tendon reconstruction.

The Mini TightRope supports and maintains the thumb and index metacarpals in proper relationship, while allowing for healing and scar tissue formation in the trapezial space. The construct consists of two strands of #2 FiberWire®, which are fixed with two oblong stainless steel buttons for cortical fixation.

For more specific information about the Mini TightRope CMC fixation technique, please see the Mini TightRope CMC surgical technique guide.
