Abstract
INTRODUCTION: Three-dimensional (3D) preoperative planning and patient-specific instrumentation (PSI) improve accuracy of glenoid component implantation in reverse shoulder arthroplasty. STEP 1 PREOPERATIVE VIRTUAL 3D PLANNING VIDEO 1: Use a 3D software tool for virtual preoperative planning of glenoid component implantation. STEP 2 PATIENT POSITIONING AND SURGICAL APPROACH VIDEO 2: Place the patient in a semi-beach-chair position and perform a standard deltopectoral approach. STEP 3 HUMERAL PREPARATION VIDEO 3: Prepare the humeral side for implantation of the humeral component using standard instrumentation. STEP 4 GLENOID EXPOSURE AND PREPARATION VIDEO 4: Expose the glenoid and prepare the glenoid surface for component implantation. STEP 5 GLENOID PREPARATION AND IMPLANTATION OF THE GLENOID BASEPLATE USING 4 PSI GUIDES VIDEO 5: Use the 4 PSI guides to prepare the glenoid for component implantation according to the preoperative plan. STEP 6 DEFINITIVE IMPLANTATION OF THE COMPONENTS AND REDUCTION VIDEO 6: Implant the glenosphere and humeral component and reduce the prosthesis. STEP 7 POSTOPERATIVE REHABILITATION PROTOCOL: Start passive and active-assisted exercises immediately, and begin muscle strengthening and active exercises at 6 weeks. RESULTS: A recent prospective, comparative study assessed the influence of 3D preoperative planning and PSI guidance of glenoid component positioning in total shoulder arthroplasty and reverse shoulder arthroplasty18.
