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
Acromioclavicular Joints, Bilateral
The acromioclavicular joints sit at the lateral end of each clavicle where it meets the acromion of the scapula, a small synovial joint stabilized by the acromioclavicular and coracoclavicular ligaments that is a common site of injury from falls onto the shoulder or direct blows to its point. Bilateral radiography is frequently performed with weighted or stress views comparing both sides, since AC joint separation is graded by the degree of clavicular elevation relative to the acromion, and subtle widening is only apparent when measured against the uninjured joint. This approach is standard when grading traumatic separations or evaluating for os acromiale and degenerative changes affecting joint alignment. The bilateral coding reflects that both joints were imaged in the same study specifically to enable this side-to-side comparison.
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.
