Proper X-ray positioning is essential because rotation, poor centring, inadequate exposure or incomplete anatomical coverage can significantly alter the apparent alignment and pathology on musculoskeletal radiographs. Orthopaedic interpretation should always begin by confirming the correct patient, side, projection, anatomical coverage and overall technical adequacy before assessing the injury itself. Important adequacy criteria differ by region, such as condylar superimposition on lateral elbow and knee views, an adequately opened ankle mortise, near-superimposition of talar domes on lateral ankle views and visualisation of C7–T1 on cervical trauma films. Measurements such as volar tilt, Baumann angle, mechanical axis deviation and joint-space width are only reliable when obtained from standardised projections. A technically inadequate X-ray should be repeated or supplemented when it cannot safely answer the clinical question, particularly before reduction assessment, operative planning or comparison with serial imaging.
