Comparison of Conventional, Patient-Specific, and Augmented Reality Navigation in Reverse Total Shoulder Arthroplasty (STEP-AR)
Comparison of Conventional, Patient-Specific, and Augmented Reality Navigation in Reverse Total Shoulder Arthroplasty: CT-Based Glenoid Positioning Accuracy and Functional Outcomes

정황
상세 설명
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.

측정값 설명 |
기간 |
|---|---|---|
|
Constant-Murley Score (Constant Score)
기간: 2 years postoperatively
|
The Constant Score is a comprehensive shoulder function assessment.
The total score ranges from 0 to 100 points.
Higher scores indicate better shoulder performance and function; lower scores indicate greater functional impairment and symptoms.
|
2 years postoperatively
|
|
American Shoulder and Elbow Surgeons (ASES)
기간: 2 years postoperatively
|
Shoulder pain and function will be assessed using the American Shoulder and Elbow Surgeons Score.
The total score ranges from 0 to 100 points.
Higher scores indicate less pain and better shoulder function.
|
2 years postoperatively
|
|
Disabilities of the Arm, Shoulder and Hand Score (DASH)
기간: 2 years postoperatively
|
The Disabilities of the Arm, Shoulder and Hand Score measures disability and symptoms affecting the upper extremity, including the arm, shoulder, and hand.
The total score ranges from 0 to 100 points.
Lower scores indicate better upper-limb function and fewer symptoms; higher scores indicate greater disability and functional limitations.

Complications and Revision Surgery
기간: Up to 2 years postoperatively
|
Occurrence of complications or revision procedures.
|
Up to 2 years postoperatively
