What anatomical structures should be visible in a correctly taken lateral oblique elbow?

In a correctly taken lateral oblique elbow view, the primary anatomical structures that should be visible include the distal humerus, proximal radius, and ulna. This positioning allows for optimal visualization of the elbow joint and essential surrounding anatomy, including the radial head and neck, which can be critical for assessing fractures or other pathologies.

The lateral oblique position is specifically designed to provide a clear view of the joint space and the alignment of the bones in the forearm. By positioning the elbow in this manner, the radiographer can distinguish between the bones, ensuring that the relationship between the radius and ulna is well-demonstrated alongside the distal humerus. This clear distinction is key for diagnostic purposes, allowing for accurate assessment of any injuries or conditions affecting these structures.
