Conditions
Brief summary
The goal of this clinical trial is to prospectively evaluate the potential benefits of injections with Augmented Reality enhanced Ulrasound versus standard Ultrasound or fluoroscopy participants where assigend for fluoroscopic joint injections oder for Ultrasound guided injection. The main question\[s\] it aims to answer are: * The primary objective is to evaluate the duration of the different interventions * the count of needle passes * assess the reduction of radiation exposure using AR US rather than fluoroscopic guidance for joint injections
Detailed description
Patients assigned for standard Ultrasound or fluoroscopic joint injection are informed about the trial. Participants are randomly assigned to the study or control intervention. 1:1 randomization is used. In both groups, data on duration of the intervention, count of needle passes, correctness of injection location and radiation exposure will be collected. The outcome measures will be compared between the groups.
Interventions
DIAGNOSTIC_TESTPuncture
Shoulder puncture with the newly designed technique using AR to overlie the US image to the imaged anatomical structures in comparision to standard US and flurosopic-guidance.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Augmented reality sonography is less time consuming | 10 minutes | Puncturing shoulders with Augmented reality sonography is faster (measuring the time in minutes and seconds) than when using standard sonography- from point of entry the skin until the target |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sonography is more efficient than fluoroscopic- guidance in shoulder puncturing | 10 minutes (ml aspirated) to 3 days (laboratory results) | More fluid (measured in ml) can be aspirated with lower false negative results (laboratory results) when puncutring shoulders with US-guidance in comparison to fluoroscopic guidance |
