Overview
The lateral elbow radiograph profiles the olecranon and distal humerus to assess alignment and displacement. The elbow is flexed 90 degrees with the forearm in neutral. This view is sensitive for detecting displaced fractures and joint effusion.
Technique
Position the elbow in true lateral with the humeral epicondyles superimposed. Use a short exposure time to minimize motion blur and include the distal humerus and proximal forearm. Ensure consistent positioning for follow up comparisons.
Clinical Indications
Lateral elbow is indicated for trauma suspected dislocation and evaluation of joint congruity. It helps identify olecranon fractures and posterior displacement. Correlate with AP and oblique views for comprehensive assessment.
Image Assessment
Evaluate the anterior humeral line and radiocapitellar alignment for pediatric fractures. Inspect the olecranon process and coronoid for cortical disruption. Document displacement and recommend orthopedic consultation when indicated.
