It may be due to trauma or avulsion, which results in tension failure because of the pull of the radiocarpal ligaments from the joint.īarton’s fracture is usually seen in young individuals, mostly males, and in elderly people, primarily females. The radiocarpal joint is fractured on the anterior side. Volar or Reverse Barton’s fracture: It is the most common wrist fracture compared to dorsal fracture. What Are the Types of Barton Fractures?īarton’s fractures are classified based on the direction of dislocation:ĭorsal or Posterior Fracture: The posterior aspect of the radiocarpal joint is fractured due to a high-velocity trauma. It occurs when a force of high velocity travels from the hand and wrist through the surface of the radius, forming the wrist joint and resulting in its subluxation or dislocation. Barton’s fracture is a shear type of fracture.

Smith’s fracture and Colles' fracture are also wrist joint fractures, but they are extra-articular in nature. It is an intraarticular fracture of the rim of the distal radius, wherein the fracture extends into the wrist joint surface. What Is Barton Fracture?īarton’s fracture is called so because it was first described by John Rhea Barton in 1938. Extrinsic radiocarpal ligaments, joint capsule, scaphoid, and lunate fossa of the radius help to stabilize the wrist joint. Eight carpal bones and two bones of the forearm, that is, the ulna and radius, constitute to form the wrist joint. It is responsible for flexion, extension, adduction, and abduction movements. Illustrations by Dr Bhargavi Sovani.The wrist joint is also called a radiocarpal joint, a complex, modified ball and socket joint connecting the forearm and hand.

Type I: These fractures are extra-articular (do not involve the joint surface) and have a simple or wedge-shaped pattern. Here are the types of fractures in the Smith classification system: The system classifies fractures based on the direction of displacement and the involvement of joint surfaces. The Smith fracture classification system, also known as the Thomas classification system, is a method used to categorize fractures of the distal radius.

Risk factors if any : High energy trauma.Ĭlassification System : Thomas Classification.

Age/Sex predilection: Younger age group.

Delayed : Malunion, tendon entrapment, carpal tunnel syndrome, complex regional pain syndrome.

May be associated with ulnar or median nerve compression.

Immediate: Pain, deformation of wrist joint, often called ‘garden-spade deformity’, swelling on the volar side.Symptoms : History of injury, followed by:.

Type 2 Smith’s fracture is a reverse Barton fracture

Reverse Barton fracture – Intra-articular distal radius fracture with volar displacement of radiocarpal joint.

Type 2 Smith’s fracture is a reverse Barton fracture (volar displacement)

Barton Fracture – Intra-articular distal radius fracture with displacement of radiocarpal joint dorsally.

You can read more about Colle’s fracture here: Colle Fracture – Distal Radial Fracture Mechanism Of Injuries In Smith And Colle Fractures Radiology Case Also a more common type of fracture overall, more common in patients with osteoporosis (thus females of old age.) Key differences in Smith’s fracture and Colles fracture owing to their mechanisms of injury, and their resultant deformities are as follows.

Colles’ fracture: Dorsal angulation of distal fragments.

If soft tissue injuries and disruption of triangular fibrocartilage complex is suspected: MRI.

In case of comminuted fracture and intra articular extension CT may be needed for planning surgical management.

For primary diagnosis and to differentiate from Colles fracture and other distal radial injuries: Wrist radiographs.

Need to check for concomitant other fractures and misalignment of other joints in the region of the wrist.

May be extra articular or may extend intra-articularly.

Distal radial fracture with volar displacement of distal fragment.

Pathophysiologyĭistal radial fracture occurring due to fall on outstretched hand, or force to dorsal aspect of distal forearm.
