Elbow AP
4
Feb

Overview

The AP elbow radiograph evaluates the distal humerus proximal radius and ulna. The patient extends the elbow with the palm up to obtain a true AP projection. This view is essential for detecting fractures and joint effusion.

Technique

Center the detector to the elbow joint and ensure the humeral epicondyles are parallel to the detector. Use appropriate exposure and immobilize the limb to reduce motion. Include the distal humerus and proximal forearm in the field.

Clinical Indications

AP elbow is indicated for trauma pain and limited range of motion. It helps detect supracondylar fractures radial head injuries and joint effusions. Additional lateral and oblique views complement the AP projection.

Image Assessment

Assess cortical continuity and joint alignment and look for fat pad signs indicating occult fracture. Evaluate the radial head neck and coronoid process for injury. Correlate with clinical findings and consider CT for complex fractures.

Elbow Lateral

Overview

The lateral elbow radiograph profiles the olecranon and distal humerus to assess alignment and displacement. The elbow is flexed 90 degrees with the forearm in neutral. This view is sensitive for detecting displaced fractures and joint effusion.

Technique

Position the elbow in true lateral with the humeral epicondyles superimposed. Use a short exposure time to minimize motion blur and include the distal humerus and proximal forearm. Ensure consistent positioning for follow up comparisons.

Clinical Indications

Lateral elbow is indicated for trauma suspected dislocation and evaluation of joint congruity. It helps identify olecranon fractures and posterior displacement. Correlate with AP and oblique views for comprehensive assessment.

Image Assessment

Evaluate the anterior humeral line and radiocapitellar alignment for pediatric fractures. Inspect the olecranon process and coronoid for cortical disruption. Document displacement and recommend orthopedic consultation when indicated.

Elbow Radial Head View
4
Feb

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.
