Plain film radiography is often the initial imaging modality used to evaluate bones and joints. Key factors that determine the radiographic appearance of structures include composition, thickness, and contrast medium usage. Standard views such as anteroposterior, lateral, and oblique are used to demonstrate anatomy while minimizing radiation exposure. Interpretation of radiographs involves assessing alignment, bone density, cartilage spaces, and soft tissues for abnormalities that may indicate conditions such as trauma, degeneration, or disease.
