Fluoroscopic visualization of anatomical fracture reduction and correct implant placement for the proximal forearm can be greatly facilitated using the following views:
The following represent ideal imaging with the patient placed in the supine position. The posture of the arm and forearm remain the same for patients in lateral decubitus and prone positions.
The orientation of the C-arm has to be adjusted accordingly.
In case the elbow cannot be fully extended (eg 20° flexion) the AP view can be compensated by extending the shoulder as illustrated (eg 20°).
The optimal view is obtained when the:
The following lines and landmarks can be observed:
This view is particularly useful to identify:
The optimal view is obtained when:
The following lines and landmarks are seen:
The radial head is superimposed on the proximal ulna and has to project posteriorly to assess the coronoid process.
The humerus is rotated internally until the olecranon, the tip of the coronoid and the anteromedial facet of the coronoid are visible.
Overlap of distal humerus with the tip of the coronoid can be avoided by bringing the elbow into extension.
