The introduction section of a scientific article is one of the most essential components, as it establishes the scientific foundation of the study and connects the reader with its objective. This section defines the general context of the topic, presents the specific scientific or clinical problem, identifies the gap in the existing literature, and provides a logical rationale for the research. A practical introduction demonstrates the originality and scientific value of the study from the outset, offering a compelling entry point for the reader. This review article examines the structure of the introduction section in academic writing, highlighting key structural principles, narrative strategies, and common mistakes through example-based analysis. With a particular focus on orthopedic and traumatology research, it aims to guide young researchers and clinicians in crafting compelling and publishable introductions to their work.
