Baseplate fixation in reverse shoulder arthroplasty: influence of intraoperative guidance on postoperative outcomes

Year: 2025

Type: article

Abstract: In reverse total shoulder arthroplasty, precise positioning of the glenoid baseplate is essential for optimizing biomechanics and implant longevity. This narrative review introduces modern guidance modalities (patient-specific instrumentation, computer-assisted navigation, and augmented reality intraoperative navigation) and compares available literature on implant alignment accuracy, patient-reported outcomes, and complication rates. Although patient-specific instrumentation and computer-assisted navigation consistently improve alignment with preoperative plans and reduce errors in guide pin and screw placement, short-term measures of strength, mobility, and patient-reported outcomes are similar to those achieved with conventional freehand methods. However, guided approaches demonstrate a reduction in the risk of complications in the short term. This suggests that the primary clinical advantage of these modern techniques is reducing complications and potentially improving long-term implant outcomes.
