All-Arthroscopic Treatment of Glenoid Rim Fractures.

We describe an arthroscopic technique for the management of glenoid rim fractures. It is performed with the patient placed in lateral decubitus position. The fracture is assessed through the anterosuperior portal, and the fragment is mobilized. A special glenoid guide is used from the posterior portal to reduce the fragment and to create 2 tunnels through the glenoid and through the glenoid rim fragment. Two pairs of round buttons are connected with high-strength sutures and are tightened posteriorly. This allows strong fixation of the fractured fragment and avoids all the anterior structures since all the instruments are inserted posteriorly.
