Radial Head Fracture
What Is a Radial Head Fracture?
A radial head fracture involves a break in the radial head, which is the rounded top part of the radius bone that meets the humerus at the outer side of the elbow joint. It plays a critical role in forearm rotation (turning the palm up or down) and elbow stability.
These fractures are common, especially among adults, and often occur as a result of a fall on an outstretched hand (FOOSH). Depending on the extent of the fracture, it may range from a small crack to a multi-fragmented injury involving joint surfaces.

Causes and Risk Factors
- Falling onto an outstretched hand with the elbow partially flexed
- Sports injuries, particularly in activities with falls or impact (e.g., skateboarding, snowboarding)
- Motor vehicle accidents
- Direct trauma to the lateral aspect of the elbow
- Osteoporosis increasing bone fragility
Symptoms
- Lateral elbow pain (outer side of the elbow)
- Swelling and tenderness near the radial head
- Difficulty or pain with forearm rotation
- Limited elbow extension and flexion
- A clicking sensation or locking, particularly in complex fractures
- Inability to bear weight on the affected arm
Diagnosis
- Physical exam, checking for tenderness, range of motion, and mechanical block
- X-rays are the primary imaging modality
- CT scan may be needed for detailed assessment in comminuted or intra-articular fractures
- Evaluation for associated injuries such as:
- Elbow dislocation
- Coronoid process fracture (as part of the “terrible triad”)
- Ligamentous injury (LCL, MCL)
Treatment
Non-Surgical Treatment
- Suitable for Type I (non-displaced or minimally displaced) fractures
- Treatment plan includes:
- Short-term immobilization in a sling
- Early motion exercises to prevent stiffness
- Pain control with NSAIDs
- Return to full activity in a few weeks for uncomplicated cases
Surgical Treatment
- Recommended for Type II or III fractures that are displaced, fragmented, or cause mechanical blockage
- Surgical options:
- Open reduction and internal fixation (ORIF) with screws or plates
- Radial head excision in select cases (not typically in younger, active patients)
- Radial head arthroplasty (prosthetic replacement) for complex, non-repairable fractures
- Goal is to restore elbow stability and motion while minimizing complications
Recovery Outlook
Most fractures heal within 6 to 10 weeks, depending on severity and treatment
Physical therapy is key to restoring motion, especially supination and pronation
Patients typically return to normal function within 3 to 4 months, though minor stiffness or discomfort may persist
Early motion is essential to avoid long-term elbow stiffness

Patient Testimonials
highly skilled surgeon
“Dr. Kvitne operated on my shoulder 3 years ago and I had a perfect recovery and no problems since and I do not see a scar. He is kind with a great bedside manor and a highly skilled surgeon.”
Dr. Kharrazi truly got me back on my feet—literally.
One year ago, I tore several ligaments in my knee, and now I’m able to do the things I enjoy again.
His expertise, knowledge, and confidence are what made me choose him as my surgeon, and I will always be grateful to him and his entire team. Rudy, his assistant; Norma, who was always so prompt with all of my emails; and Blanca, who helped with forms—each of them made a difference. I can’t thank them enough for being there with me every step of the way.
