Guided to Success: Optimizing Implant Positioning With Global Positioning System (GPS) Navigation in Total Shoulder Arthroplasty

We present the case of a 48-year-old male with severe right glenohumeral osteoarthritis who experienced progressive pain and functional loss despite extensive conservative management. Given his high activity level and preserved rotator cuff, he underwent a global positioning system (GPS)-navigated anatomic total shoulder arthroplasty (aTSA) using the ExactechGPS system (Exactech, Inc., Gainesville, FL). The procedure was uncomplicated, and postoperative rehabilitation progressed without limitation. Postoperative imaging demonstrated accurate component positioning with correction of posterior humeral head subluxation. This case highlights the short-term clinical and radiographic outcomes following navigation-assisted aTSA in a younger, active patient.
