Operation Definition
Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate
Procedure Overview
This family covers plain film x-ray imaging of the non-axial upper bones, a body system that includes the clavicle, scapula, humerus, radius, ulna, and the bones of the wrist and hand. A single exposure of external radiation passes through the limb and is captured on a photographic or digital plate, producing a flat two-dimensional image of bone alignment and density. It remains the first imaging study ordered for suspected fractures, dislocations, or growth plate injuries of the arm, wrist, or hand.
Because it is fast, inexpensive, and low in radiation dose compared to cross-sectional imaging, plain radiography is used both for initial injury evaluation and for follow-up checks during fracture healing, such as confirming that alignment has been maintained after a cast is applied.
A technologist positions the limb and takes one or more views, often front and side angles, so that the ordering clinician can assess the bone from multiple perspectives without needing a more elaborate study.
Anatomy & Axis Detail
Sternoclavicular Joint, Left
The left sternoclavicular joint links the medial end of the clavicle to the manubrium and first costal cartilage, forming the only true articulation between the arm and the trunk. Plain radiography of this joint is technically challenging because its oblique plane and the overlying sternum and mediastinal structures obscure standard frontal views, so angled projections are typically used to open the joint space for evaluation. This study is ordered after trauma such as a fall onto the shoulder, or when infection, inflammatory arthritis, or degenerative change is suspected at this specific joint rather than the shoulder or acromioclavicular joint more laterally. Specifying the left side matters because sternoclavicular pathology, particularly posterior dislocation, carries distinct risk to underlying mediastinal structures compared to the right.
Coding & Documentation
The code assigned depends on the exact bone or joint region imaged, so documentation needs to specify whether the study covered the shoulder girdle, humerus, forearm, wrist, or hand rather than a vague reference to "the arm." A frequent error is coding a two- or three-view series the same way as a single-view study when the number of views does not itself change the root operation but the body part selected must still match the anatomy actually described in findings, not just the order requisition. Coders should also confirm laterality is documented, since left, right, and bilateral studies carry distinct qualifiers.
Commonly Confused With
This family is commonly confused with fluoroscopy of the same bones, which produces a real-time moving image rather than a single static exposure and is used for dynamic assessment such as joint reduction or hardware placement rather than routine fracture survey. It is also confused with CT of the non-axial upper bones, which is reserved for more complex fracture patterns, surgical planning, or when plain films are inconclusive, and uses a different imaging modality value entirely.
