Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Over the past decade, 3D printing has become increasingly accessible and cost-effective, offering systems and materials suitable for home use. 3D printing is a technology that streamlines production by translating computer-generated models into physical objects, layer by layer. In comparison to other tissue engineering and rapid prototyping methods, 3D printing boasts numerous advantages, such as exceptional precision, rapid production, cost-effectiveness, and seamless integration. Utilizing 3D models can significantly enhance the comprehension of intricate structures for medical professionals and students alike. Common materials used in 3D printing include robust nylon, aluminum, gypsum, textile components, polylactic acid, and resin. Among these, photosensitive resin stands out, as it enables the creation of higher-quality, more intricate structures that closely resemble real tissues, offering a smoother finish devoid of visible raw material textures.

This study's primary objective was to assess the suitability of tissues produced by a 3D resin printer in anatomy education, with the aim of enhancing hands-on training through direct manipulation of fractured bone models.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Two groups as intervention and control groups. Assessments will be performed before intervention, and after the theorical/practical lectures.

Primary Study Purpose

OTHER

Blinding Strategy

SINGLE

Outcome Assessors

Due to the study design, control group will not receive any fractured models for practical lectures therefore only outcome assessor will be blinded to group allocation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Fractured Model Group

All participants will receive 60 minutes training on anatomy and pathophysiology of theoric wrist fractures. After lecture completed, the Fractured Model Group will engage in a 2-hours hands-on practical session in the laboratory, working with wrist fracture models.

Group Type OTHER

Clinical Anatomical Education with Fractured Bone Models

Intervention Type OTHER

Participants will undergo a 2-hour training session, consisting of 60 minutes of theory and 60 minutes of practice. The theoretical lesson, supported by 2D images illustrating wrist anatomy, types of fractures, and rehabilitation based on fracture type, will be simultaneously delivered to both groups. Following this, the practical group will receive a 60-minute hands-on session using 3D-printed digital models of radius and ulna fractures. These training sessions will be scheduled in the morning hours, on a day when students have no other classes between 9 am and 12 pm, to minimize mental fatigue and exhaustion. In the practical session, anatomical structures, their relationships, and arrangements will be demonstrated to the practice group using a model of a fractured wrist.

Standard Anatomic Model Group

All participants will receive 60 minutes training on anatomy and pathophysiology of theoric wrist fractures.After lecture completed, the Standard Anatomic Model Group will engage in a 2-hours hands-on practical session in the laboratory, working with standard anatomical wrist models.
