Clavicle AP is an anteroposterior X‑ray view focused on the clavicle, obtained with the patient upright or supine and the X‑ray beam directed front‑to‑back. It helps detect fractures, displacement, malunion, and bone lesions. A cephalic tilt of the beam may be used to project the clavicle clear of the chest wall. It’s a primary, quick imaging study for suspected clavicular injury.

An oblique view is an angled x‑ray projection taken between the frontal (AP/PA) and lateral planes to visualize anatomy obscured by overlapping structures. By rotating the patient or beam (commonly about 45°), it improves detection of fractures, joint alignment, small bone detail, and soft‑tissue relationships in areas like the spine, ribs, wrist, and ankle. Oblique views complement standard projections for clearer diagnosis.

The optimal x‑ray for the clavicle is an AP view with cephalic angulation (AP axial), typically 15–30° cephalad. This projects the clavicle above the thorax, improving visualization of the shaft and medial/lateral ends and better demonstrating displacement. Additional oblique or axillary views can be obtained for complex fractures or to assess the AC/SC joints if initial images are inconclusive.

A lateral X‑ray is a true side view taken at 90° to the front‑to‑back axis, showing depth, alignment and anterior‑posterior relationships to localize lesions. An oblique X‑ray is taken at an angle (often 30–45°) between front and side, highlighting anatomy hidden on AP/lateral views—useful for facet joints, certain ribs, scaphoid detail and detecting subtle fractures or joint space abnormalities.

A left shoulder AP is an anteroposterior X‑ray view of the left shoulder where the beam passes from front to back. It images the clavicle, acromioclavicular joint, glenohumeral joint and proximal humerus to evaluate fractures, dislocations, degenerative changes, infection or arthritis. It can be taken upright or supine with varying arm rotation to highlight specific structures.

An oblique radiographic position is one in which the patient is rotated so the X‑ray beam enters at an angle between frontal (AP/PA) and lateral planes. This angled projection separates overlapping structures, improving visualization of bones, joints, and soft tissues. Obliques are named by the side closest to the image receptor or by rotation direction (e.g., RAO, LAO, RPO, LPO) and aid in detecting fractures and alignment.
