Three-dimensional printed flexor tendon repair simulator promotes medical student surgical interest

Introduction: This study sought to determine whether hands-on exposure to a 3D printed flexor tendon repair simulator could help identify and promote early medical student interest in surgical subspecialties. Methods: A 3D printed flexor tendon repair simulator was developed and produced. Using this device, five flexor tendon repair workshops were held for preclinical medical students. Each workshop included a lecture on functional hand anatomy, physical exam findings, repair technique, and post-operative rehabilitation, and a hands-on training session where students practiced flexor tendon repairs on our 3D printed simulator. Outcome measures included pre- and post-workshop questionnaires to assess anatomical knowledge, perceived suturing skills, and attitude towards surgery. Results: Forty-four medical students attended the five workshops. Compared to baseline pre-workshop scores, anatomical knowledge scores increased by 57.25% on post-workshop evaluation (28.75% vs. 86.00%, p
