CT-guided Navigation in Shoulder Arthroplasty

Abstract

Successful anatomic and reverse total shoulder arthroplasty require a detailed understanding of each individual patient’s pathology. Advances in preoperative imaging continue to give surgeons a greater ability to customize implants to recreate native anatomy. Technological advancements have attempted to harness this information in the form of patient-specific instrumentation and more recently computed tomography-guided navigation. However, goals of shoulder arthroplasty remain the same: precise implant placement in order to maximize glenohumeral range of motion and stability while minimizing impingement to increase implant longevity. This manuscript reviews current literature with regard to importance of anatomic restoration of the glenohumeral joint and how computed tomography-guided navigation can be applied to improve accuracy and reproducibility in total shoulder arthroplasty.
