190 – SURGICAL SIMULATORS AND HIP FRACTURES: A ROLE IN RESIDENCY TRAINING?



Abstract

Purpose: Orthopaedic residency training requires intellectual and motor skill development. In this study we aim to develop a model to evaluate junior resident proficiency and efficiency versus senior residents in the placement of a center-center guidewire during fixation of an intertrochanteric proximal femur fracture utilizing a computer-based haptic simulator. We hypothesize the junior residents will utilize more fluoroscopy and require more time to complete the task.

Method: Post-graduate year residents (PGY) 3–5s, labeled Group II, placed a single central guide pin into a femoral head utilizing a surgical simulator four times. PGY 1–2s, labeled Group I, completed the same task six times. The residents were then evaluated based on final tip-apex distance (TAD), fluoroscopy time, time to complete the task, total number of distinct attempts at pin placement for each femur construct as well as final three-dimensional location of the pin from the isometric center of the femoral head. This project was approved by the institutional IRB.

Conclusion: In this study we displayed that based on our simulator model there was no statistical difference between Group I and II in time to completion, final placement on AP view, and tip-apex distance. There was a statistically significant difference in the anterior/posterior placement of the wire between the two groups, fluoroscopy time, and number of attempts per trial. Our findings suggest a computer based surgical simulator can identify measurable differences in surgical proficiency between junior and senior orthopaedic residents.
