Exploring the generalizability of wire navigation skills attained through simulator training.

Area of Science:

• Orthopaedic surgery simulation
• Surgical skills training
• Medical education technology

Background:

• Wire navigation is crucial for orthopaedic procedures.
• Previous simulators demonstrated skill transfer for specific tasks.
• Generalizability of simulator-trained skills across different procedures remained unstudied.

Purpose of the Study:

• To determine if simulator training for femoral neck fracture fixation improves performance in intertrochanteric fracture wire placement.
• To assess the generalization of surgical skills acquired through simulation.

Main Methods:

• 160 residents participated in a study at fracture courses.
• Baseline assessment of center-center wire placement was performed.
• Residents received simulator training on femoral neck fracture fixation.
• Post-training assessment evaluated wire placement on a simulated intertrochanteric fracture.

Main Results:

• 129 residents completed the study.
• Significant improvements in wire placement accuracy and efficiency were observed post-training.
• 91% of residents with below-average baseline scores improved, with an average score increase of 0.9.

Conclusions:

• Simulator training for femoral neck fractures enhances residents' ability to place guide wires accurately for intertrochanteric fractures.
• Generalizable wire navigation skills reduce errors and improve overall surgical performance.
• Training was most impactful for residents with the greatest initial deficits.
