Fracture of the distal radius can occur with injuries that exert much less force, e.g. falling from standing height. Pathophysiology. Force applied longitudinally or obliquely to the hand and wrist is absorbed by the distal radius because it is the load-bearing bone in the forearm. Structure The radius is between 8 to 10.5 inches long in adults. It averages 9.5 inches in men and 8.8 inches in women. 2  The distal epiphysis of the radius (far end at the wrist) averages about an inch wide.

In regards to distal radius fractures, it is important to be familiar with the anatomy around the distal radius and there are several places that must be observed on an x-ray when diagnosing a The radius is one of two forearm bones and is located on the thumb side. The part of the radius connected to the wrist joint is called the distal radius. When the radius breaks near the wrist, it is called a distal radius fracture. The break usually happens due to falling on an outstretched or flexed hand. A distal radius fracture almost always occurs about 1 inch from the end of the bone. The break can occur in many different ways, however.

The distal ulna articulates with the sigmoid notch of the radius. Type I: stable Avulsion fractures of the tip of the ulnar styloid and stable fractures of the ulnar neck have a good prognosis. Following reduction of the radius the DRUJ is congruent and stable. Extraarticular unstable fractures however, require plate fixation.

No need to register, buy now! Negative ulnar variance also increases as the X-ray beam moves proximally3. Finally, wrist deviation should be noted in the assessment of the PA view. In radial deviation, lunate is half on and half off the ulnar border of the radius, whereas in ulnar deviation, the lunate is completely congruent with the radius. Radius and Ulna Vidyadhar Upasani Henry Chambers INTRODUCTION Forearm fractures, especially about the wrist, are among the most common pediatric injuries. When a child falls off a bike, scooter, or skateboard, the upper extremity bears most of the force, particularly the forearm and wrist, because the arms are often used to brace one's fall: this… Forearm X-Ray.

The radius pivots around the ulna to produce movement at the proximal and distal radio-ulnar joints. Anatomy associated with distal radius fractures is the: radioulnar joint, the sigmoid notch, lunate fossa, the scaphoid fossa, and the ridge between the two fossa. X-ray films were then taken to define the margins and bony landmarks. The lunate facet surface area (53%) was found to be slightly larger than the scaphoid facet surface area (47%).
