Microsurgical Simulation Exercise for Surgical Training

Abstract:

Objective Initial training for orthopedic surgical residents (postgraduate years 1-5) in microsurgery using the Turkey wing model and evaluation of their proficiency. Design Residents were given a questionnaire on their comfort level with microsurgery and microsurgical knowledge, followed by a lecture on the subject. They watched a surgical dissection and repair of the Turkey wing's neurovasculature. Residents performed the dissection and repairs of the artery, vein, and nerve. A postquestionnaire was administered following the simulation exercise. Their performances on repairs were graded and results compared by academic year. Setting and Participants A total of 21 orthopedic surgery residents were recruited from Stony Brook University Medical Center, Stony Brook, NK. Results This training activity resulted in significant improvements in both microsurgical knowledge (41%) and comfort (37%). Senior residents scored significantly higher than juniors on 6 microsurgical parameters. The largest effect was in nerve repair showing 4 parameters that differed significantly between groups. Conclusion Microsurgical techniques require extensive training to master. The Turkey wing model for repair of the artery, vein, and nerve represents a realistic simulation of a human hand artery, vein, and nerve. It provides an inexpensive method for residents to practice on real tissue for improving microsurgical technique.
