Barton Fractures: Causes and Treatment

Barton fractures represent a significant type of wrist injury that can have profound implications on hand function if not correctly managed. Named after John Rhea Barton, an American surgeon, this fracture involves the distal radius and is often accompanied by dislocation.

A Barton fracture is a break in the distal end of the radius bone in the wrist, accompanied by a dislocation of the radiocarpal joint. It is an intra-articular fracture, meaning that the break extends into the wrist joint. A Smith fracture is another type of distal radius fracture, but it typically involves a break at the wrist with the palm facing downward, often resulting from a fall on an outstretched hand.

There are two primary types of Barton fractures:

These fractures, including Barton wrist fractures, are typically high-energy injuries resulting from falls, motor vehicle accidents, or direct trauma to the wrist. Barton wrist fractures specifically involve a break in the distal radius with dislocation of the radiocarpal joint, leading to potential joint damage and complications if not treated properly.

Causes of Barton Fractures

The primary causes of Barton fractures are high-impact activities or traumatic events. Common scenarios include:

Symptoms of Barton Fractures

Recognizing the symptoms of a Barton fracture is crucial for prompt diagnosis and treatment. Common symptoms include:

---

Radiological Assessment of Barton Fractures

Radiology plays a pivotal role in diagnosing Barton fractures. Standard imaging techniques include:

X-rays

Initial assessment typically involves X-rays of the wrist. These images help determine the fracture's location, type, and severity. Both anteroposterior (AP) and lateral views are essential for a comprehensive evaluation. A Barton fracture X-ray specifically helps identify the break in the distal radius and the associated dislocation of the radiocarpal joint, which is crucial for planning the appropriate treatment.

CT Scans

For complex fractures, a CT scan can provide a more detailed view of the bone fragments and the extent of joint involvement. This is particularly useful in surgical planning.

MRI

While not routinely used for fracture diagnosis, MRI can be helpful in assessing soft tissue damage and any associated ligament injuries.

Treatment Options for Barton Fractures

Treatment of Barton fractures depends on the severity of the fracture and the degree of dislocation. Options range from conservative management to surgical intervention.

Conservative Management

For non-displaced fractures or in patients where surgery is not an option, conservative management may be employed. This typically includes:

Surgical Treatment

Most Barton fractures, particularly those with displacement, require surgical intervention. Common surgical options include:

Open Reduction and Internal Fixation (ORIF)

This is the most common surgical procedure for Barton fractures. It involves:

External Fixation

In some cases, external fixation devices may be used, particularly if there is extensive soft tissue damage. These devices stabilize the fracture externally using pins and rods.

Volar Barton Fracture Treatment

Volar Barton fractures often require specific surgical approaches due to their location. The use of volar locking plates is common to provide stable fixation and promote healing.

Complications of Barton Fractures

While many Barton fractures heal without issue, complications can arise. These include:

---

Barton Fracture Management

Managing a Barton fracture involves a multidisciplinary approach, including orthopedic surgeons, radiologists, and physical therapists. Key aspects of management include:
