Area of Science:

  • Medical Education
  • Anatomy
  • Surgical Anatomy

Background:

  • Inguinal canal anatomy is crucial for understanding direct and indirect inguinal hernias.
  • Medical students frequently find inguinal canal anatomy challenging to comprehend.
  • Effective teaching aids are needed to improve understanding of complex anatomical structures.

Purpose of the Study:

  • To evaluate the effectiveness of a low-cost, low-fidelity inguinal canal model as a teaching and learning aid.
  • To assess the impact of the model on students' understanding of inguinal canal anatomy.
  • To gather student feedback on the usability and benefits of the model.

Main Methods:

  • A randomized controlled trial comparing a low-fidelity inguinal canal model (intervention group) with traditional methods (control group).
  • Students (n=106) participated in an anatomy tutorial on the inguinal region.
  • Assessment included a multiple-choice question quiz and a questionnaire for the intervention group.

Main Results:

  • Students using the model achieved higher mean quiz scores (88.31% vs 81.7%, p=0.087).
  • Positive feedback highlighted the model's simplicity and enhancement of three-dimensional understanding.
  • Students desired more hands-on interaction with the model during tutorials.

Conclusions:

  • Low-fidelity anatomical models are valuable adjuncts for teaching complex anatomical concepts.
  • The inguinal canal model effectively aids students' learning and three-dimensional spatial understanding.
  • Creating personal models may further enhance learning and retention of anatomical knowledge.
