Half pipe cannula for shoulder arthroscopy.

Abstract

Shoulder arthroscopy makes it possible to diagnose and to reconstruct different pathologies. This article describes the use of a half pipe cannula for changing instruments in shoulder arthroscopy without using a closed cannula system. The use of this new device is not an alternative to standard cannula systems, but it is very helpful for changing different arthroscopic instruments without altering the soft tissues, thus minimizing postoperative swelling.
