Navigation in Shoulder Arthroplasty Surgery

The indication of shoulder arthroplasties has increased progressively. Accurate positioning of the components may have significant implications for clinical results. The navigation used to aid in the performance of anatomical and reverse total arthroplasties has provided greater precision in implant placement, especially on the glenoid. The development of the technique, material, and prosthesis design have shown encouraging results and led to a trend toward its expansion. In this way, we estimate a higher survival of the arthroplasties resulting from lower rates of dislocation and early loosening. We aim to describe the current technique and to present the results of the literature with navigation. However, comparative clinical studies with long term follow-up are necessary to prove the efficacy in the final results of total shoulder arthroplasties.
