What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Summary

This study looks at three different ways to place the implant during reverse total shoulder replacement: conventional tools, custom-made guides, and augmented reality navigation. Researchers will check how accurate the implant position is using CT scans and measure how well the shoulder works two years after surgery. The goal is to see which method gives the best results for patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help surgeons choose the best technique for more accurate implant placement in shoulder replacement.
What could go wrong
This is an observational study with only 50 patients, so results may not apply to everyone. It does not test a new treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients who underwent reverse total shoulder arthroplasty at a single tertiary orthopedic center (Ordensklinikum Linz - Barmherzige Schwestern, Austria) between 2021 and 2024. The study population includes individuals treated using conventional instrumentation, patient-specific instrumentation, or augmented reality navigation as part of routine clinical care. Only patients with available preoperative planning data and postoperative CT imaging, as well as those eligible for clinical follow-up, were included. All participants are invited for a standardized clinical and functional assessment at 2 years postoperatively.

Ages
