What is an Elbow X-ray Interpretation?
An elbow X-ray is a quick, painless imaging test that shows the bones forming the elbow joint — the humerus, radius, and ulna. CT Read helps you understand bone alignment, joint surfaces, and important fat pad signs in clear language.
Radial Head and Capitellum
The radial head and capitellum (lower humerus) form a key articulation. Subtle radial head fractures are a common cause of elbow pain after a fall on the outstretched hand.
Olecranon and Coronoid Process
The olecranon (back of elbow) and coronoid (front) of the ulna are evaluated for fractures and alignment, both of which affect elbow stability.
Fat Pad Signs (Sail Sign)
Anterior and posterior fat pad displacement (the 'sail sign') is an important indirect sign of joint effusion that often points to an occult fracture in adults.
Joint Alignment and Soft Tissue
Overall elbow alignment is checked along with soft tissue swelling, dislocation, or signs of arthritic change in the joint.

What conditions can an elbow X-ray detect?
Standard AP and lateral elbow X-rays evaluate the distal humerus, proximal radius and ulna, and the three articulations of the elbow joint. The "fat pad sign" on a lateral X-ray is one of the most sensitive findings in all of musculoskeletal radiology.
Radial head fracture (the most common adult elbow fracture)
Often subtle on AP view — look for cortical step-off and the elevated anterior or posterior fat pad sign on lateral view, which indicates joint effusion from an occult fracture.
Supracondylar fracture (most common pediatric elbow fracture)
In children, the anterior humeral line and Baumann's angle assessed on X-ray help detect subtle supracondylar fractures, which can compromise the brachial artery if displaced.
Olecranon fracture and elbow dislocation
Posterior elbow dislocation is the most common large-joint dislocation in adults. X-ray confirms the dislocation, identifies associated coronoid or radial head fractures (the "terrible triad"), and confirms reduction.
Lateral epicondylitis ("tennis elbow") and medial epicondylitis ("golfer's elbow")
Although primarily a soft-tissue diagnosis, X-ray helps rule out bony causes and may show calcifications at the common extensor or flexor origin in chronic cases.
Elbow osteoarthritis and loose bodies
X-ray shows joint-space narrowing, marginal osteophytes (especially at the olecranon fossa) and intra-articular loose bodies that may cause locking.
Pediatric ossification centers (CRITOE)
The six elbow ossification centers appear in a specific order (Capitellum, Radial head, Internal/medial epicondyle, Trochlea, Olecranon, External/lateral epicondyle). X-ray interpretation in children requires knowledge of these ages to avoid mistaking unfused centers for fractures.
When should you get an elbow X-ray?
Elbow X-rays are ordered for almost any acute injury or persistent elbow problem.
- 1
Acute elbow trauma — falls, sports, or direct blow
An X-ray is indicated for swelling, deformity, inability to fully extend, or significant tenderness after injury. The fat pad sign alone is enough to warrant orthopedic referral.
- 2
Pediatric "pulled elbow" or fall on outstretched hand
In children under 8, supracondylar fractures and lateral condyle fractures are common and may be subtle. X-ray with comparison views of the opposite elbow is the standard first-line exam.
- 3
Chronic lateral or medial elbow pain (epicondylitis)
X-ray is used to rule out arthritis, calcifications, or stress lesions in patients with persistent pain unresponsive to conservative care.
- 4
Locking, catching or restricted range of motion
These mechanical symptoms suggest loose bodies, osteochondritis dissecans, or advanced osteoarthritis — all visible on X-ray.
- 5
Post-operative or post-reduction follow-up
After fracture fixation or dislocation reduction, X-rays confirm alignment, hardware position, and progressive healing.
Elbow X-ray vs MRI vs CT vs ultrasound
X-ray is almost always the first imaging exam, but soft-tissue and complex bony evaluations need additional studies.
| Imaging modality | Best at showing | Limitations | Cost & access |
|---|---|---|---|
| Elbow X-ray | Fractures, dislocations, fat pad sign, arthritis, loose bodies, pediatric ossification | Cannot see ulnar collateral ligament (UCL), tendons, cartilage | Lowest cost; fast results |
| Elbow MRI | UCL tears (Tommy John injury), tendinopathy, OCD lesions, occult fractures | Long scan time; expensive | High cost |
| Elbow CT | Complex intra-articular fractures, surgical planning, post-op hardware assessment | Higher radiation; no soft-tissue detail | Mid-high cost |
| Elbow ultrasound | UCL evaluation under stress, common extensor tendinosis, joint effusion, guided injections | Operator dependent; cannot evaluate deep bone | Low cost, no radiation |
How to prepare for an elbow X-ray
Elbow X-rays need almost no preparation, but a few details help image quality.
Wear a short-sleeved or sleeveless top
The arm needs to be exposed from shoulder to hand for proper positioning of AP and lateral views.
Remove watches, bracelets and jewelry from the arm
Metal artifact can obscure subtle fracture lines or fat pads.
Inform the technician about any old hardware or implants
Plates, screws or wires from previous surgery should be documented in the request.
Position the arm exactly as instructed
A true lateral view (90° flexion, thumb up, beam parallel to humeral epicondyles) is essential to detect the fat pad sign — improper positioning can hide a radial head fracture.
Limitations of AI elbow X-ray interpretation
X-ray and AI cannot replace clinical examination and advanced imaging in many scenarios.
- Ligament and tendon tears are invisible: UCL tears (Tommy John), distal biceps ruptures, and triceps tears require MRI or ultrasound. AI report being normal does not rule out these injuries.
- Pediatric interpretation requires expertise: Unfused ossification centers in children can mimic fractures and vice-versa. Always confirm pediatric AI findings with a pediatric radiologist or orthopedic specialist.
- Subtle radial head fractures are easy to miss: The fat pad sign is the only X-ray finding in up to 25% of radial head fractures. Anyone with elbow trauma and a positive fat pad sign should be treated as if they have a fracture, even if no line is seen.
