Virtual Reality-Based Simulation Training for Antegrade Anterior Column Acetabular Screw Placement in Orthopedic Residents

April 20, 2026 updated by: Samrit Tanya, Bangkok Metropolitan Administration Medical College and Vajira Hospital

Virtual Reality-Based Simulation Training for Antegrade Anterior Column Acetabular Screw Placement in Orthopedic Residents: A Crossover Randomized Controlled Trial

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

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: VR Simulation Training → Standard Training (Sequence AB)
Participants first undergo VR simulation training, followed by standard training after a washout period
Device: Virtual reality based simulation training
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.
Other: Standard Training
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.
Active Comparator: Standard Training → VR Simulation Training (Sequence BA)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Global Rating Scale (GRS) Score for Technical Performance
Time Frame: Immediately after each training session
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.
Immediately after each training session

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Procedure Time
Time Frame: Immediately after each training session
Total time required to complete the screw placement procedure (minutes).
Immediately after each training session
Fluoroscopy Time
Time Frame: Immediately after each training session
Total duration of fluoroscopic use during the procedure (seconds).
Immediately after each training session
Guidewire Reposition Attempts
Time Frame: Immediately after each training session
Number of times the guidewire trajectory is adjusted during the procedure.
Immediately after each training session
User Satisfaction (QUIS Score)
Time Frame: Immediately after each training session
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. Minimum score =1, Maximum score = 9.
Immediately after each training session

Plan to Share Individual Participant Data (IPD)?

NO

IPD Plan Description

Individual participant data (IPD) will not be shared. The dataset contains sensitive information collected from a limited number of participants within a single institution, and there is a potential risk of participant re-identification despite de-identification procedures. Therefore, data sharing is restricted to protect participant confidentiality in accordance with institutional review board (IRB) requirements.
