Distal Radius Fracture: Understanding Broken Wrists and Treatment Options
Introduction
The wrist is one of the most commonly injured joints in the body, and many wrist fractures involve the distal radius. The distal radius is the end of the larger forearm bone closest to the wrist joint. A distal radius fracture is often referred to as a broken wrist and can occur after a fall, accident, or high-energy injury. These fractures typically occur about one inch from the wrist joint and can range from simple breaks to severe fractures involving multiple broken pieces.
What Is a Distal Radius Fracture?
The radius bone and the ulna make up the forearm. The distal radius is the portion closest to the carpal bones of the wrist. A distal radius fracture happens when this part of the bone breaks, usually after landing on an outstretched hand. Wrist fractures occur more often in adults over 50 because of osteoporosis, though they can affect patients of all ages.
Different Types of Distal Radius Fractures
There are many types of wrist fractures. Understanding the type helps orthopaedic surgeons choose the best treatment.
- Colles fracture: The most common, where the radius tilts upward after a bent wrist injury. A Colles fracture occurs when someone falls onto an outstretched hand, creating an obvious deformity.
- Smith fracture: A less common fracture where the wrist bends inward, opposite to a Colles fracture.
- Intra-articular fracture: The fracture extends into the wrist joint surface, often requiring surgical fixation.
- Extra-articular fracture: The fracture does not involve the wrist joint.
- Radial styloid fracture: A break at the pointed end of the radius bone on the thumb side of the wrist.
- Comminuted fracture: Severe fractures where the bone breaks into many pieces.
- Open fracture: The broken bone pierces through the skin, increasing the risk of infection.
- Buckle fractures: More common in children, where the bone compresses but does not break all the way through.
Causes of Distal Radius Fractures
Most fractures occur when someone falls onto an outstretched hand. Other causes include:
- High-energy injuries such as car accidents or sports trauma
- Minor falls in patients with poor bone health or osteoporosis
- Work-related wrist injuries
- Direct impact to the wrist bones during contact sports
Risk factors for wrist injuries include advanced age, osteoporosis, and other bone health concerns.
Symptoms of a Distal Radius Fracture
Patients with a broken wrist may notice:
- Immediate severe pain and swelling
- Bruising and tenderness around the wrist joint
- Obvious deformity, sometimes called a “dinner fork” appearance
- Limited wrist motion and inability to bear weight
- Numbness or tingling if soft tissue or nerves are affected
A broken bone in the distal radius often prevents normal wrist function and can interfere with forearm rotation, hand strength, and grip.
Diagnosing Wrist Fractures
A proper diagnosis begins with a clinical exam, followed by imaging.
- X-rays are the standard test, showing if bones are displaced or if unstable fractures are present.
- CT scans may be ordered for complex intra-articular fractures involving the joint surface or broken pieces that are hard to see on X-ray.
- Proper diagnosis is essential for optimizing outcomes and ensuring proper alignment.
Treatment Options for Distal Radius Fractures
Early treatment is critical for proper healing and to optimize functional outcomes. The choice of treatment depends on whether the bones are aligned, the severity of the break, and patient activity level.
Non-Surgical Treatment
For non-displaced fractures where the bones are aligned:
- Closed reduction may be performed to realign broken pieces without a surgical incision.
- Splints or casts hold the wrist in the correct position while the bone heals. A removable splint may be used initially until swelling improves.
- The healing process is monitored with follow-up X-rays to confirm bones remain aligned.
- Once the cast is removed, patients typically start physical therapy to restore wrist motion and strength.
Surgical Treatment
Surgical treatment is required for displaced fractures, unstable fractures, or fractures involving the joint surface. Surgical fixation options include:
- Open reduction and internal fixation with plates and screws to hold bones aligned.
- External fixation, where a stabilizing frame is placed outside the skin, often used when soft tissue is damaged.
- Pins or wires (often titanium or stainless steel) for temporary stabilization.
- Fragment-specific fixation for complex injuries involving multiple broken pieces.
A surgical incision allows orthopaedic surgeons to restore bony alignment, repair soft tissue if needed, and stabilize the fracture for proper healing.
Open Fracture Management
All open fractures require urgent surgery. The wound and bone are cleaned, antibiotics are given to prevent infection, and either internal fixation or a temporary external fixator is placed.
Healing Process and Recovery
Fracture healing takes weeks to months, depending on patient age, bone health, and severity of the injury.
- Most fractures require immobilization for six weeks.
- After surgery, sutures are removed within two weeks, and therapy usually begins within the first month.
- Starting physical therapy early helps restore wrist motion, grip strength, and functional outcomes.
- Good bone health and compliance with therapy are critical for recovery.
Possible Complications
While most fractures heal well, complications can occur:
- Complex regional pain syndrome, a rare but painful condition affecting wrist function
- Delayed healing or nonunion
- Arthritis from damage to the joint surface
- Permanent stiffness or weakness if therapy is not started promptly
- Infection or nerve damage after severe fractures or surgical fixation
Everyday Life After a Distal Radius Fracture
After treatment, patients gradually return to normal activities. Many wrist fractures heal completely, but some patients may notice minor stiffness or aching in cold weather. Early treatment and proper alignment help optimize outcomes and minimize long-term problems.
Other Wrist and Hand Injuries
Orthopaedic surgeons also treat related conditions such as scaphoid fractures, carpal bone injuries, ligament tears, and hand surgery for soft tissue damage. Addressing bone health is important for preventing future fractures.
