Custom 3D Printed Jigs in Salvage Reverse Shoulder Arthroplasty for Failed Four-Part Proximal Humerus Fracture Fixation: A Case Report

摘要

Complications of open reduction and internal fixation (ORIF) in four-part proximal humerus fractures (PHFs) include non-union, malunion, avascular necrosis of humeral head, and glenoid defect due to implant failure. Reverse total shoulder arthroplasty is a salvage procedure for cases of failed fixation. In cases with significant abnormal glenoid anatomy, custom-made patient-specific 3D printed jigs play a major role in pre-operative planning and accurate positioning of the glenoid component, thereby improving the final outcome. We report a case of salvage reverse shoulder arthroplasty done using the patient-specific custom-made 3D printed jig.
