Study Overview
Brief Summary
This clinical trial aims to compare a Mixed Reality Viewer in the preoperative informed consent process to standard fracture visualization. The participants population are patients with an indication for surgery of a distal radius fracture, upper ankle fracture or proximal humerus fracture using plate osteosynthesis.
The main questions aim to answer are:
- Does the use of the Mixed Reality Viewer improve patient understanding?
- Does the use of the Mixed Reality Viewer improve patient satisfaction?
- Does the use of the Mixed Reality Viewer reduce patient preoperative anxiety?
Participants will have their fracture presented via the Mixed Reality Viewer. Researchers will compare standard fracture imaging using X-ray or CT scans to see if there is any difference in understanding, satisfaction and anxiety.
Detailed Description
In everyday clinical practice, patients receive a verbal explanation of their medical condition, optional treatment options, and information about the benefits, risks and complications of surgery during preoperative education. To visualize the respective fractures to the patients, they are shown using X-rays, CT scans or MRI images. However, these images are often difficult to understand without prior medical knowledge.
A better understanding of the fracture by the patients and a more comprehensible visualization of the operations can lead to better informed consent between the patients and the doctor. Consequential benefits for treatment and postoperative follow-up may follow.
The investigators hypothesis is that fracture visualization using a Mixed Reality Viewer can generate higher fracture understanding in patients. As a result of better education, this visualization method could lead to higher patient satisfaction and anxiety reduction.
Patients with an indication for surgery of a distal radius fracture, upper ankle fracture or proximal humerus fracture using plate osteosynthesis are randomized into the intervention group or the control group. Both study groups watch verbal education via a recorded video. The intervention group afterward receives a fracture visualization via mixed reality glasses. The control group receives fracture visualization via X-ray or CT scan.
In both the intervention group and the control group, the type of fracture, the extent of the fracture, the surgical method, and the benefits and risks of the surgery are explained to the patients during the visualization.

Outcomes
Primary Outcomes
Patient Understanding
Time Frame: Measurement is assessed via a questionnaire immediately after the procedure.
A questionnaire is used to determine the patients' level of understanding via content-related questions about their specific fractures. Patients answer questions on a 6-point Likert scale, with higher scores indicating better outcome.
Patient Preoperative Anxiety
Time Frame: Measurement is assessed via a questionnaire immediately after the procedure.
A questionnaire is used to determine the patient's anxiety regarding their upcoming surgical procedure. Patients answer the question on a 10-point Likert scale, with higher scores indicating worse outcome..
Patient Satisfaction with the educational process assessed by the 6-point Likert scale
Time Frame: Measurement is assessed via a questionnaire immediately after the procedure.
A questionnaire is used to determine the patient's satisfaction with the educational process. Patients answer questions on a 6-point Likert scale, with higher scores indicating better outcome.
