Barton's fracture

Introduction to Barton's fracture The longitudinal tibiofibular rupture of the distal humerus and the subluxation of the wrist are called Barton fractures, also known as Barton fractures. Depending on the mechanism of occurrence and the characteristics of the fracture line, it can be divided into the following two types: the back side type is less common, and when the palm is falling on the ground, the back of the distal radius of the humerus is caused by the back extension of the hand, and the fracture piece is multi-directional. Lateral displacement with a subluxation of the wrist. The palmar type is more common, and the hand falls on the back of the hand, so that the stress direction travels along the distal end of the humerus to the volar side, the fracture piece is displaced to the volar side, and the wrist joint also appears subluxation. Some people have included this type as a type of Smith fracture. basic knowledge The proportion of illness: 0.005% Susceptible people: adolescents and middle-aged Mode of infection: non-infectious Complications: swelling

Cause of Barton's fracture

(1) Causes of the disease

Mostly caused by indirect violence.

(two) pathogenesis

When the fall is over, the palms or hands are on the ground, so that the violence is transmitted upwards, and the joint surface of the humerus is broken by the impact of the proximal carpal bone. The fracture line is longitudinally inclined to the distal end of the humerus, and most of them are accompanied by subluxation of the wrist joint.

Barton fracture prevention

Prevention: The fracture patients are mainly adolescents and middle-aged and elderly people, followed by traffic accidents and work-related accidents and other injuries. This requires people to have a sense of prevention. When doing daily activities such as running, jumping, squatting, walking, etc., they must be psychologically prepared, concentrate, and not be numb, so that the coordination of the whole body's bones will reduce or prevent fractures. occur. Especially in the middle-aged and elderly people, osteoporosis, bones become brittle and hard, often inadvertent movements, and when the fracture occurs, immediately go to the hospital.

Barton fracture complications Complications swelling

The wrist is swollen and tender, and the joint is deformed.

Barton's fracture symptoms Common symptoms Pain in the radial part of the wrist joint Swelling and tenderness Wrist pain, wrist swelling and palmar flexion... Wrist contusion, joint swelling, wrist fracture

The wrist is swollen, mainly to the dorsal aspect of the distal radius of the humerus. The deformity is like the Coles's fracture, the tenderness is obvious, the wrist joint activity is limited, and there may be a bone rub.

Classification: According to its mechanism and fracture line characteristics, it can be divided into the following two types (Figure 1).

1. The dorsal type is more common. When the palm falls on the ground, due to the back extension of the hand, the fracture is caused by the dorsal lateral edge of the distal radius. The fracture piece is displaced to the dorsal side and accompanied by subluxation of the wrist.

2. The palm-side type is rare, and the hand falls on the back of the hand, so that the stress direction runs along the distal end of the humerus to the volar side. The fracture piece is displaced to the volar side, and the wrist joint also appears subluxation. Some people have included this type in the Smith fracture. type.

Barton fracture examination

The lateral X-ray film showed fracture on the dorsal side of the distal radius, including 1/3 of the articular surface, multi-directional dorsal and distal displacement, and the wrist joint showed a dorsal subluxation.

Diagnosis and diagnosis of Barton fracture

Traumatic history, local swelling, mainly on the wrist, protruding to the dorsal deformity, obvious tenderness, limited mobility, bone rubbing, lateral X-ray film showing fracture of the distal side of the distal bone, including 1/3 of the articular surface , more than the dorsal side and distal displacement, the wrist joint is a dorsal subluxation.
