Can an Orthopedic Hip Fracture Simulator Advance Orthopedic Residents' Hip Fracture Fixation Skills to an Expert Level?

This study was undertaken to evaluate hip fracture simulator training and orthopedic resident skill attainment. We hypothesized that after 6 training sessions, improvement in post-training scores in junior residents would exceed that of senior residents and that senior residents would attain expert level proficiency sooner. Thirty orthopedic residents from a single institution completed 6 training sessions. Sessions included a pretest, 9 training modules, and post-test. An expert score was obtained from the average scores of 8 trauma fellows and attending orthopedic traumatologists. The primary outcome measure was overall score. A single academic institution. Orthopedic residents (postgraduate years [PGYs] 1-5). Twenty-six residents completed the study. The mean overall post-training score was 87% of the expert level. Factors associated with post-training score changes were additional training sessions (4.2% improvement [p < 0.01]), time between training sessions (0.3% decrease [p = 0.05]) and PGY5 class (12.1% improvement [p = 0.03]). Fifty-four percent of residents attained the expert overall score. Expert score attainment was not associated with an additional year of training or case log volume. Post-training scores plateaued for the PGY1s and showed linear improvement for the PGY5s. Differences in trends between training levels suggest this simulator is a useful adjunct to a 5-year orthopedic residency training program.
