title: [Set-up, portals and normal exploration in wrist arthroscopy.]
abstract: Arthroscopy is an accepted technique for evaluation of intra-articular pathology and treatment of a variety of disorders even in the wrist joint. Dedicated miniaturized instrumentation is needed along with a specific traction system. The external distraction alone (dry technique) allows for complete joint exploration and several type of arthroscopic surgery, avoiding annoying leaking in the subcutaneous tissues, though further distension of the articular pouches can be achieved by saline infusion (fluid distension or wet technique). Knowledge of surface anatomic landmarks and careful surgical technique are required for proper portal placement and in order to avoid injury to the numerous noble structures crossing nearby. Description of radio- and medio-carpal portals is provided along with the different bony, condral, synovial and ligamentous structures that can be visualised or treated through each portal. Surgeon can choose the most suitable portal for scope or instruments, according to specific needs for diagnostic or therapeutic purposes.
