Elbow Radial Head View

Overview

The radial head view profiles the radial head and neck to detect subtle fractures and impaction injuries. The projection is obtained with the elbow flexed and the beam angled to profile the radial head. This view complements standard AP and lateral elbow radiographs.

Technique

Position the elbow in partial flexion and rotate the hand to profile the radial head. Use a small focal spot and tight collimation for detail. Immobilize the limb to minimize motion artifact.

Clinical Indications

Radial head views are indicated for trauma with lateral elbow pain and suspected radial head fracture. They help detect nondisplaced fractures that may be occult on standard views. CT or MRI may be used for complex or occult injuries.

Image Assessment

Evaluate radial head cortical continuity articular surface and neck for fracture lines. Assess for joint effusion and associated capitellar injury. Report findings relevant to orthopedic management.

Rib Oblique

Overview

Oblique rib views rotate the patient to project ribs away from the spine and thoracic structures. This technique improves visualization of rib contours and fracture lines. Both anterior and posterior rib segments can be assessed with targeted obliques.

Technique

Rotate the patient toward the side of interest and center the detector to the rib region. Use appropriate exposure and include the costochondral junction when indicated. Obtain both ipsilateral and contralateral obliques if necessary.

Clinical Indications

Oblique ribs are used when AP views are inconclusive or when detailed assessment of a specific rib is required. They are helpful in trauma and persistent localized pain. Correlate with clinical exam and consider CT for complex injuries.

Image Assessment

Inspect the cortical margins for discontinuity and displacement. Evaluate adjacent soft tissues and lung fields for associated injury. Report fracture location relative to anatomic landmarks for surgical planning if needed.
