[Shoulder arthroscopy in degenerative and inflammatory diseases].

A new concept of shoulder arthroscopy is presented based on experience with 800 shoulder arthroscopies. All open surgical procedure on the shoulder are preceded by arthroscopy. The procedure is performed with the patient lying on his or her side. The medium is CO2, and the advantages are less bleeding, a natural picture, no fluid edema. After diagnostic arthroscopy (with CO2), operative arthroscopy (with fluid) or open joint surgery follows. The surgery can easily be performed in the same position for good access with any approach. Preliminary diagnostic arthroscopy helps to plan the procedure (approach, additional surgery). Minimal exposure is beneficial for faster rehabilitation.
