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

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.
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.

Global Rating Scale (GRS) Score for Technical Performance
Overall technical performance score (range 6-36) assessed by two independent blinded orthopedic trauma experts using a validated Global Rating Scale. A higher score means better outcomes.
Time frame: Immediately after each training session
Procedure Time
Total time required to complete the screw placement procedure (minutes).
Time frame: Immediately after each training session
Fluoroscopy Time
Total duration of fluoroscopic use during the procedure (seconds).
Time frame: Immediately after each training session
Guidewire Reposition Attempts
Number of times the guidewire trajectory is adjusted during the procedure.
Time frame: Immediately after each training session
User Satisfaction (QUIS Score)
Participant satisfaction assessed using the Questionnaire for User Interaction Satisfaction (Likert scale). This score contains of 9-point bipolar Likert scale, the analysis focuses on Central Tendency (Mean) and Variability (Standard Deviation). A Higher mean of the score indicates better outcome.
Time frame: Immediately after each training session
