Radial Head Fracture

Q1. What is a radial head fracture?

A radial head fracture is a break or crack at the top of the radius bone, which is one of the two bones in your forearm. This specific break happens at the part of the bone that sits right at your elbow joint. It is a very common elbow injury, making up about one-third of all elbow fractures.

Q2. Where is the radial head located in my elbow, and what does it do?

Your forearm has two bones: the ulna (on the pinky side) and the radius (on the thumb side). The radial head is the knobby, disc-shaped top part of the radius bone where it meets the humerus (upper arm bone) and the ulna. It acts like a pivot, allowing you to rotate your forearm so your palm can face up or down, and it helps you bend and straighten your elbow.

Q3. What causes a radial head fracture?

The most common cause is a fall onto an outstretched hand. When you trip and put your hand out to break your fall, the force of the impact travels up your arm and jams the radius bone into the upper arm bone at the elbow. It can also be caused by a direct blow to the outer side of the elbow, or during high-impact sports and car accidents.

Q4. What are the common symptoms of a radial head fracture?

If you have fractured your radial head, you will likely experience:

• Sudden, sharp pain on the outside of your elbow.
• Swelling and bruising around the elbow joint.
• Difficulty and pain when trying to bend or straighten your elbow.
• Pain or inability to rotate your forearm (turn your palm up and down).
• Tenderness when pressing on the outside of the elbow.

Q5. How is a radial head fracture diagnosed?

Dr. Veillette or your healthcare provider will examine your elbow, checking for pain, swelling, and how well you can move your arm. To confirm the fracture and see exactly how the bone is broken, they will order X-rays. In more complex cases where the bone might be broken into multiple pieces or if there is concern about ligament damage, a CT scan or an MRI may be ordered.

Q6. Are there different types or severities of radial head fractures?

Yes, doctors use the Mason Classification system to group these fractures into four types:

• Type I (Nondisplaced): The bone has a small crack or break, but the pieces remain perfectly aligned.
• Type II (Displaced): The broken piece of bone has shifted out of its normal position.
• Type III (Comminuted): The bone is broken into multiple small pieces.
• Type IV (Fracture with Dislocation): The radial head is broken, and the elbow joint is also dislocated or has severe ligament damage.

Q7. What are the non-surgical treatment options for a radial head fracture?

Many radial head fractures (especially Type I and some Type II) can be treated without surgery. Conservative treatments include:

• Sling or Splint: A temporary sling or splint is used to keep the elbow still and support the weight of your arm for the first few days.
• Early Movement: Unlike other broken bones, it is important to start moving the elbow gently within a few days of injury to prevent permanent stiffness.
• Pain Management: Using ice packs and over-the-counter pain medications to reduce pain and swelling.

Q8. When is surgery needed for a radial head fracture?

Surgery is usually required if:

• The broken bone pieces have shifted significantly (displaced) and block you from rotating your forearm.
• The bone is broken into multiple small pieces (comminuted).
• There is a joint dislocation or severe damage to the surrounding elbow ligaments.
• The joint surfaces are no longer smooth, which could lead to early arthritis.

Q9. What does surgery for a radial head fracture involve?

Depending on how badly the bone is broken, surgery may involve:

• Open Reduction and Internal Fixation (ORIF): The surgeon puts the bone pieces back into their proper position and holds them together using small screws, pins, or a metal plate.
• Radial Head Replacement: If the bone is shattered and cannot be repaired, the broken pieces are replaced with a metal artificial radial head (prosthesis).
• Radial Head Resection: In rare cases, the broken radial head is simply removed, though this is usually done only if the elbow ligaments are stable.

Q10. What is the typical recovery timeline after a radial head fracture?

Recovery time varies based on the severity of the fracture and whether you had surgery:

• Non-surgical (Type I): Pain and swelling usually improve within 2 to 4 weeks. Most patients regain near-normal function and return to daily activities in 6 to 8 weeks.
• Surgical (Type II, III, or IV): Recovery takes longer. You may need a splint for 1 to 2 weeks, followed by physical therapy. A return to light activities takes about 6 to 12 weeks, while full recovery, heavy lifting, or sports can take 3 to 6 months.

Q11. How important is physical therapy or exercises during recovery?

Physical therapy is absolutely crucial for recovering from a radial head fracture. The elbow joint is highly prone to becoming stiff. Gently moving the elbow early on, under the guidance of Dr. Veillette or your therapist, helps restore your range of motion, strengthens the surrounding muscles, and ensures you can rotate your forearm normally.

Q12. How do I manage pain and swelling at home?

You can manage your symptoms using the R.I.C.E. method and medication:

• Rest: Avoid using the injured arm for lifting or carrying.
• Ice: Apply cold packs wrapped in a cloth to your elbow for 15-20 minutes every few hours.
• Compression: If advised by your doctor, a light compression sleeve can help manage swelling.
• Elevation: Keep your elbow elevated above heart level on pillows as much as possible, especially when resting or sleeping.
• Medication: Take pain relievers exactly as prescribed or recommended by your healthcare team.

Q13. What are the potential complications of a radial head fracture?

While most patients recover well, possible complications include:

• Elbow Stiffness: The most common complication, which is why early movement is emphasized.
• Malunion or Nonunion: The bone heals in an improper position or fails to heal completely.
• Chronic Pain or Instability: Ongoing discomfort or a feeling that the elbow is unstable.
• Early Osteoarthritis: Damage to the cartilage surface can cause wear and tear over time.
• Nerve Irritation: Temporary numbness or weakness in the hand due to nerve irritation near the elbow.

Q14. Can I expect a full recovery and normal range of motion?

For simple, nondisplaced fractures, most patients regain full or nearly full range of motion and strength. For severe fractures or cases requiring surgery, you may experience a very mild, permanent loss of extension (inability to fully straighten the arm) or rotation. However, this minor loss rarely affects your ability to perform daily activities.

Q15. When should I contact my doctor or seek immediate medical attention?

You should call your doctor or go to the nearest emergency room immediately if you experience:

• A sudden increase in pain that is not relieved by medication.
• Numbness, tingling, or a "pins and needles" feeling in your hand or fingers.
• Your hand or fingers feel cold, look pale, or turn bluish.
• Significant swelling, warmth, or redness around your elbow or incision site.
• Drainage, pus, or an unpleasant odor coming from your surgical wound.
