Anatomy Of Distal Radius

Anterior lateral posterior and medial. 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.

X Wrist Startradiology

The radius moves around the ulna at the wrist enabling us to turn our hands palm up and palm down 8.

Anatomy of distal radius. The end toward the wrist is called the distal end. The break usually happens due to falling on an outstretched or flexed hand. 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. A fracture of the distal radius occurs when the area of the radius near the wrist breaks. The distal portion of the radius has a quadrilateral cross section and includes the metaphyseal and epiphyseal regions.

Distal region of the radius. The ulna bone may also be broken. The bone also forms an ellipsoidal joint with the proximal carpal row that.

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. In younger people these fractures typically occur during sports or a motor vehicle collision. 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.

Distal radius fractures drf are common injuries. In the distal region the radial shaft expands to form a rectangular end. Anatomic features of the distal radius include the styloid process the dorsal tubercle and four surfaces.

Drfs in the times of hippocrates and galen were thought to be wrist dislocations. The wrist may be deformed. A cadaveric study of the volar distal radius was performed to better understand the anatomy relevant to the volar approach for distal radius fractures.

In the medial surface there is a concavity called the ulnar notch which articulates with the head of ulna forming the distal radioulnar joint. When the radius breaks near the wrist it is called a distal radius fracture. Distal end of radius.

The lateral side projects distally as the styloid process. What is a distal radius fracture. Symptoms include pain bruising and rapid onset swelling.

Functions of the radius it forms a hinge joint with the humerus bone which allows us to flex and extend the elbow 7. The distal end which tends to be turned slightly forwards has a somewhat triangular form. Distal radius fractures are very common.

The part of the radius connected to the wrist joint is called the distal radius. Many papers have been written about them with more than 200 having been published in the first 6 months of 2018 alone. General features of distal radius anatomy.

About 50000 occur each year in the united states. Three investigators separately or collectively dissected six cadavers and examined nine dried bones. In fact the radius is the most commonly broken bone in the arm.
