Abstract

Objective

To evaluate the utility of three-dimensional (3D) anatomical models as an educational tool among Orthopaedic surgical trainees.

Methods

Seven types of 3D anatomical models - humerus, elbow, ankle, calcaneum, knee, femur, and pelvis- based on patients' computational tomography (CT) scans were printed in the study institution and used by surgical trainees preoperatively. Responses were collected in the form of a Likert scale questionnaire. Descriptive statistics of participants’ ratings were calculated. Non-parametric analysis using Wilcoxon test and Kruskal-Wallis test was performed to determine if effectiveness varied with gender, clinical experience, and anatomical model type.

Design

Observational cross-sectional study.

Setting

Single center study.

Participant selection criteria

All participants within a period of 16 months who were Orthopaedic surgical trainees within the study institution and utilised 3D anatomical models preoperatively were selected for this study.

Outcome measures and comparisons

Primary outcome was Likert scale ratings for three aspects - understanding of patients’ anatomy, learning of a patient-specific orthopaedic condition, retention of anatomical knowledge.

Results

This study revealed that 3D anatomical models were well-received as an educational tool among Orthopaedic surgical trainees. There were no significant differences between gender, clinical experience or anatomical model type regarding 3D models in improving understanding of patient anatomy and retention of anatomical knowledge (p < 0.05). There were significant differences among participants based on clinical experience regarding the use of 3D models in learning of the patient-specific orthopaedic condition (p = 0.0106).

Conclusions

Preliminary results from this study demonstrate overall effectiveness of 3D models as an educational tool in Orthopaedic surgery, but is limited by the qualitative nature of data collected. Higher quality evidence is required to demonstrate that 3D anatomical models are effective tools to impart critical knowledge of anatomy to surgical trainees.

Level of evidence

IV.

期刊介绍： Journal of Clinical Orthopaedics and Trauma (JCOT) aims to provide its readers with the latest clinical and basic research, and informed opinions that shape today''s orthopedic practice, thereby providing an opportunity to practice evidence-based medicine. With contributions from leading clinicians and researchers around the world, we aim to be the premier journal providing an international perspective advancing knowledge of the musculoskeletal system. JCOT publishes content of value to both general orthopedic practitioners and specialists on all aspects of musculoskeletal research, diagnoses, and treatment. We accept following types of articles: • Original articles focusing on current clinical issues. • Review articles with learning value for professionals as well as students. • Research articles providing the latest in basic biological or engineering research on musculoskeletal diseases. • Regular columns by experts discussing issues affecting the field of orthopedics. • "Symposia" devoted to a single topic offering the general reader an overview of a field, but providing the specialist current in-depth information. • Video of any orthopedic surgery which is innovative and adds to present concepts. • Articles emphasizing or demonstrating a new clinical sign in the art of patient examination is also considered for publication. Contributions from anywhere in the world are welcome and considered on their merits.
