Many papers have been written about them with more than 200 having been published in the first 6 months of 2018 alone.

Anatomy of distal radius. The radius is one of two forearm bones and is located on the thumb side. Distal radius fractures broken wrist the radius is the larger of the two bones of the forearm. In fact the radius is the most commonly broken bone in the arm.

Anterior lateral posterior and medial. General features of distal radius anatomy. Distal end of radius.

A cadaveric study of the volar distal radius was performed to better understand the anatomy relevant to the volar approach for distal radius fractures. A fracture of the distal radius occurs when the area of the radius near the wrist breaks. The end toward the wrist is called the distal end.

The break usually happens due to falling on an outstretched or flexed hand. The distal end which tends to be turned slightly forwards has a somewhat triangular form. About 50000 occur each year in the united states.

The bone also forms an ellipsoidal joint with the proximal carpal row that. Three investigators separately or collectively dissected six cadavers and examined nine dried bones. The distal portion of the radius has a quadrilateral cross section and includes the metaphyseal and epiphyseal regions.

The wrist may be deformed. Distal radius fractures drf are common injuries. The part of the radius connected to the wrist joint is called the distal radius.

The inferior distal surface of the lower end of the radius bone provides a lateral triangular area for articulation along with the scaphoid and a medial quadrangular area for articulation with the lateral components of the lunate. Symptoms include pain bruising and rapid onset swelling. In the medial surface there is a concavity called the ulnar notch which articulates with the head of ulna forming the distal radioulnar joint.

Its distal carpal articular surface concave from before backwards and slightly so from side to side is divided into two facets by a slight antero posterior ridge. When the radius breaks near the wrist it is called a distal radius fracture. The ulna bone may also be broken.

Distal radius fractures are very common. In younger people these fractures typically occur during sports or a motor vehicle collision. The lateral side projects distally as the styloid process.

The radius moves around the ulna at the wrist enabling us to turn our hands palm up and palm down 8. In the distal region the radial shaft expands to form a rectangular end. A distal radius fracture also known as wrist fracture is a break of the part of the radius bone which is close to the wrist.

Functions of the radius it forms a hinge joint with the humerus bone which allows us to flex and extend the elbow 7. Drfs in the times of hippocrates and galen were thought to be wrist dislocations. Anatomic features of the distal radius include the styloid process the dorsal tubercle and four surfaces.
