A thorough analysis of the growth plates, or physes, is essential to distinguish a normal variant from a traumatic Salter-Harris fracture. The alignment of the three bones—the humerus, radius, and ulna—must be harmonious.
Normal Left Elbow X-Ray: Key Differential Diagnoses for Common Variants and Pathologies
Technical Execution and Patient Positioning Obtaining a diagnostic left elbow xray begins long before the exposure button is pressed. Accurate collimation to the joint line reduces scatter radiation and improves image contrast, allowing the radiologist to assess the integrity of the radiocapitellar joint.
The lateral view, often the most informative for assessing joint alignment, mandates that the elbow is flexed to exactly 90 degrees, with the humerus perpendicular to the image receptor. In a truly normal, non-pathological elbow, the anterior fat pad should appear as a thin, triangular lucency between the distal humerus and the anterior coronoid process.

The standard anteroposterior (AP) view requires the patient’s elbow to be fully extended, with the palm facing upward (supinated). Conversely, a posterior fat pad, which is normally not seen, is always pathognomonic for an intra-articular process, such as a fracture or significant synovitis.
