STATE OF THE ART IN CMC 1

Join leading hand surgeons from around the world for a two-day symposium dedicated to CMC1 osteoarthritis and prosthesis surgery.

Through six highly practical oriented sessions, we will examine patient profiling, treatment algorithms, implant evolution and design, and key surgical techniques from preoperative imaging to precise implantation.

Interactive debates will tackle complications, revision decision-making, and real case discussions, culminating in an exploration of emerging concepts and future innovations in CMC1 management.

Delivered by a distinguished international faculty, the programme offers exceptional scientific depth and a truly global perspective.

A premium learning experience providing hand surgeons with practical, evidence-based strategies for immediate use in operative room.

Please note that this symposium is conducted entirely in English.
