A radial head fracture is a break in the top of the radius, one of the two bones in the forearm. The radial head is the part that connects to the elbow joint and allows for rotation of the forearm (like turning a doorknob or palm up/down). When this area fractures, it can cause pain, swelling, limited elbow motion, and difficulty rotating the forearm.

An analogy…

Imagine your forearm bone (radius) as a screwdriver and the radial head as the handle that allows it to twist smoothly. If the handle cracks, you lose smooth movement, that’s exactly what happens in a radial head fracture.

What causes a radial head fracture?

The radial head sits on the outer part of the elbow joint and plays a key role in forearm rotation and elbow stability. A fracture usually occurs when someone falls onto an outstretched hand, and the force travels up the forearm to the elbow. It may also occur from a direct blow to the elbow. Sometimes, it happens along with other injuries like elbow dislocation or ligament sprains.

What are the signs and symptoms of a radial head fracture?

• Pain on the outer side of the elbow
• Swelling and tenderness around the joint
• Difficulty bending, straightening, or rotating the forearm
• Clicking or catching during movement
• Bruising and stiffness
• Pain worsens with gripping, lifting, or pushing

What tests are used to diagnose a radial head fracture?

How long does a radial head fracture take to heal?

Recovery depends on how severe the fracture is and whether or not surgery is needed. If the fracture is non-displaced or minimally displaced, it usually heals with immobilisation and rehab in 4 to 6 weeks. If the fracture is displaced or involves multiple fragments, surgical fixation may be required, and full recovery may take 3 to 6 months, including a structured rehab program to restore strength and motion.

How does a radial head fracture happen?

• Falling on an outstretched hand
• Direct impact to the elbow during sports, accidents, or contact activities
• Work or sports that involve risk of falling or impact
• Osteoporosis or bone weakness, which increases fracture risk
• Poor protective reflexes or balance during falls

What treatment can help a radial head fracture?

• Short period of immobilisation with a sling or brace
• Pain management with ice and anti-inflammatories
• Early gentle movement exercises to prevent joint stiffness
• Manual therapy and rehab to restore function
• Return to activity gradually under guidance

What exercises or stretches can I do for a radial head fracture?

• Gentle elbow range of motio
• Wrist and grip strengthening
• Shoulder mobility and stability work to offload the elbow
• Forearm rotational exercises
• Gradual return to functional and sport-specific movements
