Radial Head Fracture — AI-Powered Imaging Analysis
Upload elbow X-rays or MRI to evaluate radial head fractures. AI assesses fracture type using the Mason classification and associated injuries.
Overview
Radial head fractures are the most common elbow fracture in adults, typically resulting from a fall onto an outstretched hand. The Mason classification guides treatment decisions. Our AI consortium evaluates fracture pattern, displacement, comminution, and associated injuries including the terrible triad (radial head fracture + coronoid fracture + elbow dislocation).
Common Symptoms
- Lateral elbow pain after fall on outstretched hand
- Pain with forearm rotation (pronation/supination)
- Swelling over the lateral elbow
- Limited range of motion, especially extension
- Tenderness directly over the radial head
Key Imaging Findings
- Fracture line through the radial head or neck
- Mason classification: Type I (non-displaced), II (displaced), III (comminuted)
- Anterior or posterior fat pad sign on lateral X-ray
- Associated coronoid process fracture
- MCL or LCL injury on MRI
- Occult fracture visible on MRI but not X-ray
Frequently Asked Questions
What is the fat pad sign on elbow X-ray?
The fat pad sign indicates elbow joint effusion. A visible posterior fat pad (sail sign) is always abnormal and suggests an occult fracture even if no fracture line is visible. An elevated anterior fat pad is also suspicious. If the fat pad sign is present with a normal X-ray, MRI should be considered.
What is the Mason classification?
The Mason classification grades radial head fractures: Type I (non-displaced or minimally displaced, treated conservatively), Type II (marginal fracture with displacement, may need fixation), Type III (comminuted, often requires radial head replacement), Type IV (associated with elbow dislocation — the terrible triad).
