What exactly is the internal brace in arthrex suspensionplasty with internal brace for cmc arthroplasty? and which is better, this or arthrex mini-tightrope? thanks?

You should search more info from this link: https://www.arthrex.com/ then discuss the option with a hand orthopedist.

You should discuss your options with your hand surgeon. Both the internal brace and the mini-tightrope can be used as part of the cmc arthroplasty procedure but neither is required. Excellent outcomes can be achieved by a skilled hand surgeon with any number of cmc arthroplasty techniques.
