Comparison of Conventional, Patient-Specific, and Augmented Reality Navigation in Reverse Total Shoulder Arthroplasty (STEP-AR)

Descripción detallada
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.

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Accuracy of Glenoid Component Positioning
Periodo de tiempo: up to 2years postoperatively
|
Comparison of preoperative planning parameters with postoperative CT-based measurements of glenoid component positioning, including inclination, version, implant size, and screw placement.
|
up to 2years postoperatively
|
Medidas de resultado secundarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Constant-Murley Score (Constant Score)
Periodo de tiempo: 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)
Periodo de tiempo: 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)
Periodo de tiempo: 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.
|
2 years postoperatively
|
|
Complications and Revision Surgery
Periodo de tiempo: Up to 2 years postoperatively
|
Occurrence of complications or revision procedures.
|
Up to 2 years postoperatively
