Nowadays, osteoarthritis of the thumb is breakthrough time. Thaks to the new biomechanical findingswhich ligament is more important for stability, and the histological finding of tha mechanoreceptors in theligaments, that open up a new range of therapeutic possibilities with neuromuscular control. The classification ofEaton and Littler is still currently in force, although there are new proposals as the radiological index for osteoarthritisof the thumb. Treatment has changed little, the trapeziectomy remains as an option, but many techniqueshave been developed without any studies that confirm the superiority of one with the other ones. Recently, newtechniques such as arthroscopy, or use Tightrope® type devices are beginning to use, without yet having longtermstudies that tell us whether they are really effective.
