Brief Summary

The goal of this study is to find out if virtual reality (VR) training helps orthopedic residents improve their skills in placing screws in the pelvic bone. The study will also compare VR training with standard training to see which method is more effective and easier to use. The main questions it aims to answer are: Does VR training improve performance compared to standard training? Does VR training help reduce procedure time and X-ray use? Do participants prefer VR training? Researchers will compare VR training with standard training using a crossover design, where all participants receive both types of training. Participants will: Take part in both VR and standard training sessions Practice the procedure on a bone model Be evaluated by experts on their performance Complete a satisfaction questionnaire

  Immediately after each training session

• User Satisfaction (QUIS Score)

  Immediately after each training session

Study Arms (2)

ACTIVE COMPARATOR

Participants first undergo standard training, followed by VR simulation training after a washout period.

Device: Virtual reality based simulation training; Other: Standard Training

Interventions

Virtual reality based simulation training DEVICE

Participants train using a VR platform simulating antegrade anterior column screw placement. Three-dimensional pelvic models reconstructed from CT data are integrated into a virtual operating environment. Participants interact using a VR headset with simulated instruments and fluoroscopic imaging, allowing repeated practice with real-time feedback. Duration: up to 30 minutes.

Standard Training → VR Simulation Training (Sequence BA); VR Simulation Training → Standard Training (Sequence AB)

Standard Training OTHER

Participants perform screw placement on a pelvic sawbone model under fluoroscopic guidance using standard instruments, including a 2.0 mm K-wire. The setup simulates real operative conditions. Duration: up to 30 minutes.

Standard Training → VR Simulation Training (Sequence BA); VR Simulation Training → Standard Training (Sequence AB)
