A distal ulnar fracture occurs when there is a break in the ulna, one of the two bones in the forearm, near its wrist end. This type of fracture can happen due to trauma, such as a fall onto an outstretched hand or a direct blow to the forearm. 

At Palms Physiotherapy & Allied Health, our experienced team of physiotherapists, occupational therapists, and exercise physiologists is dedicated to helping you recover fully from a distal ulnar fracture, restore movement, and get back to your usual activities.

Symptoms of a Distal Ulnar Fracture

The symptoms of a distal ulnar fracture vary depending on the severity of the injury. Common signs include:

1. Pain and Tenderness

• Pain is typically felt along the little finger side of the forearm, near the wrist.

• Tenderness may be present at the fracture site when touched.

2. Swelling and Bruising

• Swelling around the wrist and forearm is common, often accompanied by bruising in the area.

• The wrist may appear deformed if the fracture is displaced.

3. Limited Range of Motion

• Difficulty moving the wrist and forearm, especially when trying to rotate or grip objects.

• Inability to bend or extend the wrist fully.

4. Weakness and Numbness

• Numbness or tingling in the hand or fingers may occur if the fracture impinges on nearby nerves.

• Reduced grip strength and difficulty with daily tasks like writing, holding utensils, or turning door handles.

Causes of Distal Ulnar Fractures

Distal ulnar fractures typically occur due to high-impact trauma. The most common causes include:

1. Fall onto an Outstretched Hand (FOOSH)

• Falling onto an outstretched hand is one of the most common causes of distal ulnar fractures. The force from the impact can cause a break at the distal end of the ulna, especially if the wrist is extended.

2. Sports Injuries

• Contact sports such as football, rugby, or martial arts can lead to distal ulnar fractures from falls or direct hits to the forearm.

3. Motor Vehicle Accidents

• A high-impact accident or collision can result in direct trauma to the forearm, leading to fractures of the ulna.

4. Osteoporosis

• People with weakened bones, such as those with osteoporosis, are at increased risk for fractures from even minor trauma or falls.

Diagnosing a Distal Ulnar Fracture

Accurate diagnosis of a distal ulnar fracture requires a physical exam and imaging tests. Your physiotherapist or doctor will typically use:

1. Physical Examination

• Your healthcare provider will examine your wrist and forearm for signs of swelling, bruising, and tenderness.

• Specific tests to check the range of motion and strength may be performed.

2. X-rays

• X-rays are the primary diagnostic tool for confirming a distal ulnar fracture. They can show the location, type, and severity of the fracture.

• In some cases, X-rays may reveal a fracture that is not immediately visible, so follow-up imaging may be necessary.

3. CT or MRI Scan

• In cases where the fracture is complex or difficult to see on X-rays, a CT scan or MRI may be used to get a more detailed view of the fracture.

Treatment for Distal Ulnar Fractures at Palms Physiotherapy & Allied Health

Treatment for a distal ulnar fracture depends on the type and severity of the break. At Palms Physiotherapy & Allied Health, our multidisciplinary team provides individualized care to help you heal and regain optimal function in your wrist and forearm.

1. Non-Surgical Treatment (For Non-Displaced Fractures)

• Immobilization: Non-displaced fractures are typically treated with a cast or splint to immobilize the wrist and forearm, allowing the bone to heal in the correct position.

• Rest: Rest is important to avoid further injury and ensure the fracture heals properly.

• Pain Management: Over-the-counter pain medications such as NSAIDs may be recommended to reduce pain and swelling.

2. Surgical Treatment (For Displaced or Complex Fractures)

• If the fracture is displaced (the bones are misaligned), surgery may be required to reposition the bones and hold them in place with plates, screws, or pins.

• Open Reduction and Internal Fixation (ORIF) may be recommended if the fracture is unstable and cannot heal properly without surgical intervention.

3. Physiotherapy and Rehabilitation

• Once the bone begins healing, physiotherapy is essential to restore function, flexibility, and strength in the wrist and forearm.

• Range of motion exercises are introduced to improve mobility and prevent stiffness in the wrist joint.

• Strengthening exercises are designed to restore grip strength and promote the use of the wrist and forearm for daily activities.

• Manual therapy may be used to help reduce pain and improve the mobility of the forearm and wrist.

4. Occupational Therapy

• Occupational therapy may include the use of splints or braces to support the wrist during rehabilitation.

• Adaptive strategies for using the wrist while it heals can be provided, ensuring that you can perform necessary tasks without risking further injury.

Recovery and Rehabilitation

The recovery timeline for a distal ulnar fracture can vary depending on the severity of the injury and the treatment method used. For non-displaced fractures, it may take approximately 6-8 weeks for the bone to heal. Displaced fractures or fractures requiring surgery may take 3 to 6 months for full recovery, depending on the complexity.

During the rehabilitation phase, it is essential to follow a structured program that includes:

• Range of motion exercises to restore flexibility.

• Strengthening exercises to regain muscle strength in the forearm and wrist.

• Functional training to help you return to your normal daily activities, including tasks that require wrist mobility and strength.
