Study Overview
Brief Summary
This monocentric observational cohort study compares conventional instrumentation, patient-specific instrumentation, and augmented reality navigation in reverse total shoulder arthroplasty. The primary objective is to assess the accuracy of glenoid component positioning based on postoperative CT data. Secondary objectives include evaluation of functional outcomes and clinical performance at mid-term follow-up. Patients who underwent surgery between 2021 and 2024 are followed up clinically at 2 years postoperatively.
Detailed Description
This study investigates the accuracy and clinical relevance of different planning and implementation techniques in reverse total shoulder arthroplasty. Patients treated at a single orthopedic center between 2021 and 2024 were included. Three established surgical approaches were analyzed: conventional instrumentation, patient-specific instrumentation, and augmented reality navigation.
Initial data collection included retrospective and prospective assessment of preoperative planning parameters and their intraoperative implementation. Postoperative evaluation included low-dose CT imaging to assess glenoid component positioning accuracy.
The current phase of the study focuses on long-term clinical outcomes, with a standardized 2-year follow-up including clinical examination and validated functional outcome scores. No additional imaging is performed as part of the follow-up phase.
Patients were not randomized; group allocation reflects the surgical technique used at the time of treatment.
