Due to the current trend of decreasing contact hours and less emphasis being given to the basic science courses in the pre-clinical years of medical education, it is essential that new approaches to teaching gross anatomy are investigated to ensure medical students are being adequately exposed to anatomical content. This study retrospectively analyzed practical examination data from four medical gross anatomy classes (N = 569) to ascertain which pedagogical approach, student participation in the dissection process, or interaction with prosected specimens is best for teaching the anatomy of the hand and foot. Data analysis involved the use of propensity score matching, a nonparametric preprocessing statistical approach which ensures accurate representation of the true treatment effect by balancing cohorts prior to statistical analysis. Statistical analysis indicated that those students who were exposed to the anatomy of the hand through interactions with prosected specimens performed 5.6% better (P = 0.012) while for the foot, students who interacted with prosections performed 13.0% better (P < 0.001). Although limited, data from this study suggest that utilizing prosections of the hand and foot seems to be a more advantageous pedagogical approach for teaching these regions than requiring students to dissect them.
