Glenohumeral arthrodesis is an end-stage salvage operation that has traditionally been performed in an open fashion. In recent years an arthroscopic approach has been described. The purpose of this report was to present an arthroscopic glenohumeral arthrodesis technique with the assistance of O-armebased navigation. An illustrative case example is presented. This technique allows not only a minimally invasive glenohumeral arthrodesis but also precise screw fixation by navigation, which may be particularly useful in cases of limited bone stock and/or bony deformity.
Glenohumeral arthrodesis is an end-stage surgical option indicated in cases of permanent brachial plexus injury, post-tumor resection, unreconstructable glenohumeral arthritis, chronic infection, and refractory instability with rotator cuff and deltoid dysfunction. Traditionally, the procedure has been performed in an open manner with screw and/or plate fixation.
