The elbow series is a set of radiographs taken to investigate elbow joint pathology, often in the context of trauma. It usually comprises an AP and lateral projection, although other non-standard, modified projections are utilized for specific indications.
Indications
Elbow x-rays are indicated for a variety of settings including:
- trauma
- bony tenderness
- suspected fracture of the proximal radius and ulna
- suspected fracture of the distal humerus
- radial head dislocations
- obvious deformity
- detecting joint effusions
- arthritis
- infection
Projections
Standard projections
- AP
- demonstrates distal humerus, proximal ulna, and radius
- shows both the medial and lateral epicondyles in profile
- lateral
- best demonstrates the ulna-trochlear joint, coronoid process, and the olecranon process
- used to assess both the anterior humeral line and the radiocapitellar line
Modified trauma projections
- horizontal beam lateral
- modified lateral projection that requires little to no patient movement
- produces a diagnostic lateral/AP projection without risking patient pain
- acute flexion AP
- modified AP projection when the patient cannot straighten the arm
- inferosuperior view
- modified elbow projection for patients in acute flexion greater than 90 degrees
Additional projections
- Coyle's view
- an axial projection that focuses on the radial head, used when radial head fractures are suspected
- external oblique
- an additional projection often performed to demonstrate the radial head free from superimposition
- medial oblique view
- projection demonstrating the coronoid process in profile
- supracondylar AP
